Structural detailed solution of shell and tube heat exchanger

Structural detailed solution of shell and tube heat exchanger The shell-and-tube heat exchangers mainly include structural types such as fixed tube-plate heat exchangers, floating-head heat exchangers, U-tube heat exchangers, and packing-type floating-head heat exchangers. The structure of the fixed-tube heat exchanger is simple. The low manufacturing cost can obtain a smaller shell inner diameter. The tube process can […]

A brief introduction to the inner and outer diameter micrometer of steel pipes

The outer diameter micrometer and inner diameter micrometer are the most used in the production and inspection process of steel pipes, precision steel pipes and seamless steel pipes. Today we will talk about the inner and outer diameter micrometers. 1. Outside diameter micrometer Micrometer outside diameter often referred to as micrometer, it is more precise than the […]

Application of stainless steel pipe in petroleum and petrochemical industry

1 Application of Stainless Steel in Petroleum and Petrochemicals The most commonly used classification of stainless steel is classified according to the structure of the steel and can generally be divided into ferritic stainless steel, austenitic stainless steel, martensitic stainless steel, duplex stainless steel, and precipitation hardened stainless steel. In petroleum and petrochemical applications, austenite stainless steel, […]

Welding method of long-distance pipeline

Long-distance pipeline welding method: First, manual welding (1) Arc welding of electrodes is sensitive and cumbersome, and has strong conformability. At the same time, due to the continuous improvement of electrode performance, its deposition efficiency and mechanical properties can still meet the requirements of today’s pipelines. In particular, welding welding is more commonly used. . The […]

Effect of solid solution process on stainless steel pipe fittings

The production cost of pipe fittings should be taken into consideration in the production enterprises of stainless steel pipe fittings, but the factors of preventing corrosion and improving the quality of the products should be taken into consideration. Therefore, it is necessary to adopt the solid solution process in the production process of stainless steel pipe fittings […]

Manufacturing methods and product standards for stainless steel fasteners

There are different types of stainless steel fasteners that provide different levels of corrosion resistance and strength. They are used in corrosive industrial and marine environments, equipment, construction and construction applications. These products are available in all stainless steel designs and are used to join other metals such as copper, aluminum, carbon steel and zinc. The specifications […]
