Table 1: Classification of industrial Metal Pipe Fittings
Industrial Metal Pipe Fittings are mainly used in petroleum, petrochemical, chemical, natural gas, shipbuilding, electric power, medicine, gas, heat and other industries, especially in the industry, especially in the industrial, industrial, industrial pipe fittings products with strong special features, high added value and wide application characteristics. Rock gas, marine engineering and nuclear power and other emerging areas of great space, the prospects should be optimistic.
First, the status of industrial metal pipe industry development
China’s industrial metal pipe fittings industry, enterprises, small scale, relatively scattered production situation. As of the end of 2013, China has a total of more than 40,000 industrial metal pipe fittings business, small-scale enterprises, the majority of private enterprises, the annual production capacity of 1,000 tons in general; annual sales of more than 20 million yuan of about 200 enterprises. 2007-2013, China’s metal pipe production showed a year-on-year trend, but since 2011, growth has declined. Industrial metal pipe products mainly supply petrochemical, natural gas, ship, electricity, heat, medicine and other industries. With the national efforts to strengthen energy investment, the discovery of a large number of new oil fields and the strategy of West-East Gas Transmission, the “gasification strategy” of various provinces and cities in the country, deep processing of coal resources, strategic reserves and more use of aviation fuel will be greatly enhanced Pipe fittings industry’s sustainable development.
The main raw material of industrial metal pipe is steel products, including carbon steel and stainless steel and other materials, the industry’s upstream industry is steel ingot, steel pipe, steel manufacturing. With the development of materials technology, titanium-based alloys, nickel-based alloys and other new materials are also beginning to apply a large number of pipe fittings industry. The price, variety and quality of iron and steel products have an important influence on the industrial metal pipe fittings industry. China is a large steel producer, steel pipe, steel, ingot products sufficient supply of raw materials to ensure that the industry supply. But in recent years, with the rising prices of iron ore, steel prices continue to rise, reducing the domestic industrial metal pipe industry profits.
Industrial metal pipe industry is widely used in various fields, including petrochemical, shipbuilding, electric power, natural gas, medicine, food and many other industries. In the 12th Five-Year Plan, the State Council proposed to speed up the development of new energy sources, promote the clean and efficient use of traditional energy sources, actively develop hydropower under the premise of ecological protection, develop nuclear power on the basis of ensuring safety, strengthen power grid construction, Improve the oil and gas transmission pipeline network, expand oil and gas strategic reserves. Downstream energy, power industry development requires a lot of equipment investment, and equipment manufacturing performance, specifications, materials of different industrial metal pipe products. Downstream enterprises and industrial metal pipe fittings enterprises to establish long-term stable cooperative relations to ensure the safe operation of equipment and adequate supply. The development of the downstream industry to ensure that the industrial metal pipe industry has a stable and growing market demand.
The domestic industrial metal pipe fittings industry, the general market competition, such as ordinary carbon steel, small-caliber varieties of products such as adequate supply, but the large diameter, composite materials, high-performance (high temperature, low temperature resistance, high pressure, corrosion) and for special industries Demand for the development of new products in short supply. Oil and gas industry needs to build long-distance pipeline large diameter, high pressure pipe, oil cracking industry in urgent need of high temperature, high pressure collection of pipe fittings, chemical industry required for the production of stainless steel metal matrix composite pipe fittings, power industry required Can withstand supercritical or even ultra-supercritical working state of the alloy, thick-walled pipe, chemical, shipbuilding industry, the need for standardized pipe system modules are in short supply range of products.
Mainly due to cost factors, developed countries, the production of metal pipe less, need from China, India, Brazil, China Taiwan and other countries and regions, the Chinese metal pipe export market in the future have greater room for growth. In recent years, thanks to the huge demand of the downstream industry, industrial metal pipe industry, the overall market demand for rapid growth, the market supply is also increasing rapidly.
In the course of exploiting the downstream customer market, the major enterprises in the industrial metal pipe fittings industry rely on their unique advantages in customer resources to form a concentrated market in different directions, mainly in the petrochemical, shipbuilding, power and other industries.
Second, the industrial metal pipe industry competition
In the current metal pipe industry, small diameter, low pressure, mainly to carbon steel pipe fittings, mainly used in the metal pipe without special technical requirements of the operating environment, known as the general metal pipe; and large diameter, medium High pressure, the use of high-grade steel, alloy steel or special metal material manufacturing, its application of the industry has strong professional and targeted pipe fittings, known as the special steel pipe fitting industrys or high-end pipe fitting industrys. From the industrial metal pipe industry competition, the domestic production of metal pipe business is very large, but most of the smaller, mainly engaged in general metal pipe manufacturing, the real can produce high-quality, high-tech high-end metal pipe business is less. In the low-end pipe market, there is fierce competition. The supply and demand of high-end products such as large-caliber, composite materials and high-performance products are insufficient. The industry is in the low-end market and the high-end market is not perfect.
China’s industrial metal pipe industry competition has the following characteristics:
① enterprises generally smaller scale. China’s annual production capacity of pipe fittings enterprises generally 1,000 tons in the following, most companies use small workshops, small factories type of production. On the one hand, the pattern of market demand caused by the other hand, most of the pipe fittings for private enterprises, by the capital, talent, market development and other factors, do not have sustainable development.
② enterprises lack the core technology competitiveness. The process of cutting, heat treatment, welding and anticorrosion of ordinary pipe production process is not high. The production process mainly depends on manual operation, basically do not use modern automatic control equipment, and do not have the technical innovation and product development ability.
③ product structure is irrational. China’s industrial metal pipe production capacity is mainly concentrated in the small and medium-diameter pipe fittings or carbon steel pipe fittings field, large diameter or high-end pipe production capacity is insufficient. China’s industrial metal pipe fittings enterprises from the product specifications, the main production of small-caliber tube; from the product material division, the main production of carbon steel pipe fittings.
The downstream market demand for large diameter products and high-performance alloy steel, stainless steel and new composite materials generally inadequate supply of the industry need to develop a number of carbon steel, stainless steel, alloy steel and other new composite pipe production capacity of enterprises, To solve the unreasonable product mix situation.
④ affected by the downstream industry fluctuations. The downstream industries of the industrial metal pipe industry are the lifeline industries of petrochemical, shipbuilding and electric power industries. These industries have high market concentration and some enterprises are monopolized or semi-monopolized, and can rely on huge demand to form buyer monopolies. The industrial metal pipe industry, market concentration is low, a single enterprise market negotiation capacity is limited, product sales by the downstream industry as a whole the greater impact of volatility.
Industrial metal pipe fittings mainly for supporting the use of downstream industries, industry enterprises are mainly distributed in the petrochemical, shipping, electricity and other downstream industries concentrated in the eastern region. The rapid development of the downstream industry will drive large diameter, composite materials, high performance and high reliability of the strong demand for pipe fittings, especially with China’s urbanization infrastructure to accelerate the development of the central and western regions, oil and gas field development, the world ship order transfer, Resource exploration, construction of nuclear power plants and other construction projects, will have been in short supply the market there is a greater gap between supply and demand. Therefore, large-diameter, composite materials, high-performance and high reliability of the pipe fittings production enterprises will gather in China’s industrial metal pipe the most competitive areas.
Industrial metal fittings industry regional agglomeration characteristics are obvious, mainly in the east and north China, the main industrial agglomeration area has four: Jiangsu Jiangyin, Yangzhou area; Hebei Cangzhou, Langfang area; Liaoning Yingkou, Fuxin area; Zhejiang Wenzhou area.
The following are the number of competition from the industry, industry growth rate, exit barriers, competition analysis of the existing competition in the enterprise. Analysis of available, the industry is in the mature stage, the quality of the industry as a whole uneven, most enterprises focus on low-end products, price war, the existing business competition.
Table 2: Competitive analysis of existing metal pipe fittings
With the international industrial gradient transfer, manufacturing has been to China, India and other developing countries. Therefore, foreign companies on the domestic industrial metal pipe fittings business a smaller potential threat. At the same time, China’s industrial metal pipe industry has matured, new entrants into the cost of a higher threshold. As a result, the potential threat to China’s industrial metal pipe fittings is small. Industrial metal pipe fittings is an essential part of industrial pipe, there is no substitute products; but with the downstream industry of industrial metal pipe product quality, material and other requirements, there are high-end products in the low-end products instead.
Third, the industrial metal pipe industry market prospects
The downstream applications of industrial metal fittings are extensive and involve the major industries of the national economy. Among them, petrochemical, nuclear power, thermal power, shipbuilding and military industries are the representative industries for their applications, especially the application of special metal fittings in these industries. .

As the long-term operation of petrochemical equipment in high temperature or low temperature, high pressure, strong corrosion and other special circumstances, special metal materials in the petrochemical equipment in the proportion of demand for high, the current petrochemical industry, industrial metal fittings in the proportion of special metal pipe is about 50 / RTI & gt; With the increase in the proportion of poor use of crude oil, hydrogenation technology to promote the application of long-distance oil and gas pipeline construction, new coal chemical industry to accelerate the development trend of the application of special metal fittings will be more and more widely. The traditional single anti-corrosion technology and materials can not meet the needs of the development of oil and gas fields, therefore, oil and gas fields on the high steel grade, high corrosion resistance, low temperature and other pipe needs continue to increase. As the oil and gas field medium composition, pressure, temperature and other large difference between the corrosion environment, a large number of high corrosion resistance alloy will cause increased production costs and corrosion of the waste of alloy materials, so the development of both oil and gas fields to ensure safety and transportation, A new type of bimetallic composite materials has become the focus of the major oil and gas companies, bimetallic composite pipe and pipe products, the market demand is also the market demand is very high. getting bigger. “Petroleum and chemical industry,” second five “plan” forecast, “second five” during the industry average growth rate will remain at 10% or more to petrochemical industry, industrial metal pipe industry, the average annual growth rate of 10% and special metal pipe fittings A conservative estimate than 50% in 2015, China’s petrochemical industry, industrial metal pipe fittings and special metal pipe market size will reach 40 billion yuan and 20 billion yuan.
2. coal chemical industry
China’s coal reserves are rich, accounting for 11.60% of the world’s total coal reserves. Since the founding of the country’s primary energy production and consumption of coal in the long-term ratio of more than 70%. According to the Ministry of Land and Resources data, as of the end of 2010, China’s total coal resources forecast of about 5.6 trillion tons, of which 1340.83 billion tons of resources have been identified. Relying on the rich coal resources, China’s coal chemical industry has been a good development. “Eleventh Five-Year” period, China’s coal chemical engineering construction total investment of about 500 billion yuan, China’s nitrogen fertilizer, calcium carbide, coke and other traditional coal chemical products production capacity, continue to rank in the world. At the same time, with the role of oil substitution of new coal chemical technology has made great progress, driven by high oil prices, the emerging coal chemical industry is the emergence of rapid development momentum. “Twelfth Five-Year” period of coal chemical industry investment will be China’s coal chemical metal pipe fittings and special metal pipe to bring new market demand.
3. nuclear power industry
In the construction of nuclear power, fluid gas delivery requires the use of a large number of industrial pipelines, pipe connections to use a large number of pipe fittings. The medium of the nuclear tube is mainly composed of saturated steam, condensed water, radioactive water vapor heavy water, irradiation corrosive substance, radioactive medium, dilute sulfuric acid and lye, carbon dioxide, sodium, helium, oil and vacuum. Special, complex, harsh, coupled with a large amount of large, demanding, so a large number of nuclear power fittings using nickel-based alloys, titanium, zirconium and other special metal materials. In recent years, China’s nuclear power infrastructure investment accelerated. According to China Electricity Council statistics, in 2011 China’s nuclear power infrastructure investment reached 74 billion yuan, from 2007 to 2011, the average annual growth rate of nuclear power investment of more than 70%. From the perspective of China’s energy demand and supply situation, the development of nuclear power is an inevitable choice to ensure energy security in China. In October 2012, the State Council approved the “Mid- and Long-Term Development Plan for Nuclear Power (2011-2020)”, Kilowatts of nuclear power installed capacity of the target, under construction nuclear power installed capacity will be slightly more than 20 million kilowatts is expected in 2015 China’s nuclear power with industrial metal fittings and special metal fittings market capacity will reach 2.9 billion and 1.7 billion. The market of nuclear power fittings is divided into two parts: pipe fittings and pipe fittings. Many enterprises make petrochemical and thermal power market for a long time. The production technology is mature and it is easier to enter the nuclear power market after upgrading according to the nuclear power quality assurance system. At present, there are nearly 20 domestic and foreign manufacturers of pipe fittings which are qualified to participate in nuclear power projects. Chinese and foreign enterprises basically share half of the country, but foreign integrated group companies possess nuclear island main steam piping and fittings experience, Grade pipe market, the vast majority of domestic enterprises can only provide the nucleus level 2, level 3 of pipe fittings.
4. thermal power industry
Thermal power plants require a significant amount of pressure piping and fittings to carry high-temperature fluids. In order to improve the efficiency of coal-fired power generation and protect the ecological environment, China has vigorously developed super-critical thermal power units with low coal consumption, low pollution and high efficiency in recent years. Thermal power units Industrial metal pipe fittings, especially those used in the four major thermal power plant pipe (main steam pipe, reheat steam pipe hot section, reheat steam pipe cold section and high pressure water supply pipe) to be subject to long-term high temperature and high pressure steam and high-speed fluid substances Erosion corrosion, the quality of the four major pipeline operation is essential. With the development of large-capacity, high-parameter, ultra-supercritical and water-saving environment-friendly units, the four large pipe fittings are required to increase the caliber and have better performance of high temperature resistance, high pressure resistance and corrosion resistance. , The use of P91, P92, P22 and WB36 have excellent heat resistance, high pressure performance of special metal materials, special metal pipe fittings are used for a large number of supercritical, supercritical parameters such as thermal power units in the pipeline.
5. shipbuilding industry
As an important component of marine pipeline system, industrial metal pipe fittings are widely used in ships and offshore engineering equipment, and play the role of fluid and gas medium transportation. By the impact of the global economic crisis lag, the international shipping market downturn, China’s shipbuilding industry, industrial output growth slowed, but overall to maintain growth. The marine engineering equipment industry, as the material and technical foundation for the development and utilization of marine resources, has become the most promising field in the field of shipbuilding in the context of the increasing importance of continental shelf resources in China.
Marine and marine engineering in the fluid, gas medium, including crude oil, chemical gases and other corrosive substances, while the ship metal pipe fittings exposed to long-term humid air, marine equipment, pipe fittings need to be soaked in seawater, so strong corrosion resistance Of the special metal materials such as titanium, nickel-based alloys have been gradually applied to ship metal pipe fittings, especially marine equipment, metal pipe manufacturing.
6. the military industry
