stainless steel pipes

The most serious problem in the application of stainless steel pipes in soil and water treatment is the corrosion of the medium. In the soil, the corrosivity is usually classified by its resistivity. The experiment shows that if the soil pH is more than...

There are many ways of anticorrosive treatment on stainless steel pipes . By improving the surface treatment methods and processes of stainless steel pipes, many practical applications can be improved. The first is cleaning stainless steel pipe. It can...

When stainless steel pipes are cold-drawn or cold-rolled, some defects will inevitably occur. These defects will affect the quality of the finished stainless steel pipe products. Therefore, preventive measures must be taken for the formation of these...

The solution treatment of stainless steel pipes are very powerful, mainly reflected in three aspects. The following is a detailed description of austenitic stainless steel pipes. The austenitic stainless steel tube is softened by solution treatment. Usually,...

When do stainless steel pipe need passivation? Conventionally, when the stainless steel pipe is corroded after the welding process and subjected to strong pollution, it must be passivated. The preferred passivation method is as follows. In the case of...

Stainless steel pipes should have different forms of packing according to their product type, finish, size and transportation mode. Because the stainless steel pipe is usually the pipe, the pressure pipe, the mechanical pipe and the decorative pipe, and...

In the practical application of stainless steel pipes , there will be no other stainless steel pipes or flanges, fittings. At this time to meet the requirements of the use, it is necessary to ensure that the quality of the butt joint between the stainless...

During the welding process of stainless steel pipes , cracks sometimes occur in the weld zone. According to the time and temperature of formation, there are mainly three forms of cold cracks, hot cracks and reheat cracks; according to the formation site,...

In the welding process of stainless steel pipes , some defects may cause stress concentration, bearing capacity, shortened service life, and may even cause brittle fracture. Usually in the welding technical regulations, it is absolutely impossible for...

The finished stainless steel pipes , unless used under deep underground conditions, need to be polished to ensure that the surface is bright and beautiful. Currently used polishing methods mainly include mechanical polishing, chemical polishing, and electrochemical...
