The corrosion resistance of duplex stainless steel and corrosion fatigue performance is outstanding, widely used in equipment made of refining and chemical industry, salt industry and other industries in the atmospheric vacuum distillation unit and catalytic cracking and hydrocracking, continuous sulfate cooking or intermittent cooking device, compressor cooler operation environment is very bad. In spite of the […]
Characteristics of stainless steel welded pipe and its processing technology
Stainless steel welded pipe is also called pipe, most of which is a stainless steel tube which is made of stainless steel tape after curling the equipment. Its production and processing technology is simple and efficient, the specifications are varied and the investment is low, but the strength of the product is generally lower than that […]
How to use the bottom welder in stainless steel pipe welding
The process of welding stainless steel pipe usually consists of three kinds of soldering, filling and cover welding. The backing welding is the most important part of the stainless steel tube welding process, which is related to the quality and progress of the project. It includes two processes: back filling argon and not argon filling. The backside […]
What are the factors affecting the annealing of stainless steel pipelines
In the process of demolition of old buildings, the removal of stainless steel pipeline is an area requiring special attention. This article mainly talks about the construction methods under the demolition of stainless steel pipelines. When removing the old pipelineline of stainless steel pipelineline, most of them first use plasma cutting machine to cut the pipelineline, then […]
What are the factors affecting the annealing of stainless steel pipes
There are many factors that affect the brightness of stainless steel pipes after annealing. The main factors include the temperature, atmosphere, seal, air pressure and water vapor content in the furnace. These factors are described in detail below. The first is to look at the annealing temperature, to see if it has reached the corresponding temperature. Because […]
Cleaning of stainless steel elbow and advantages of material selection
When the stainless steel elbow is corroded, a special cleaning agent is needed to remove the rust. And in the daily use of the regular cleaning. For example, when it is found that the surface of stainless steel elbow is dusty or easier to remove, it can be cleaned directly with warm water or weak detergent. Of […]
Classification of some application fields of stainless steel welded pipe
Stainless steel welded pipe is mainly used in landscape decoration, light industry, pharmaceutical industry, water supply and other industries. It is also applied to petrochemical industry. It usually selects medium and low pressure pipelines above the size of 159mm. Besides, the automobile muffler can also be made of stainless steel welded pipe. Stainless steel seamless pipes […]
Welding process in application process of stainless steel pipe
With the continuous progress of the material processing technology, the stainless steel pipe has also ushered in a new development opportunity. Typical applications such as automobile exhaust pipe, fuel pipe, injection nozzle and other automobile components. In the production of stainless steel pipes, a flat stainless steel belt is first formed and then rolled into a circular […]
Surface nitriding process of stainless steel plate
Stainless steel sheet is widely used. The surface modification of sheet metal is a low-cost way and can significantly enhance the hardness and wear resistance of materials. Because the surface oxide film of the stainless steel plate will exist, it is very difficult to make ordinary gas nitriding. Although the surface activated stainless steel can be […]
What are the functions and characteristics of hot rolled stainless steel plates
According to the different production and processing technology, the mainstream stainless steel plate includes two kinds, the hot-rolled stainless steel plate and the cold rolled stainless steel plate. Next, the role and application advantages of the hot-rolled stainless steel plate are described below. The characteristics of the hot rolled stainless steel plate are three points. First, the […]
