The processing technology of stainless steel pipes also needs to pay attention to several points:

(1) Cutting of stainless steel pipes. In the process of cutting stainless steel pipes, special stainless steel cutting machinery should be used as much as possible according to the actual processing conditions, and the use of plasma machine flames to cut stainless steel should be avoided as much as possible. In addition, for the cut stainless steel blanks, carbon steel materials must not be used as the blank shelves.

(2) School pipe of stainless steel pipe. In the process of schooling stainless steel pipes, strict requirements must be placed on the schooling environment, and schooling must be carried out on a specific platform for stainless steel pipes. Remember that during the production process of stainless steel pipes, no contact with carbon steel materials is allowed. This is mainly because once the iron powder in Ji steel comes into contact with stainless steel, it will cause stainless steel contamination and cause varying degrees of corrosion.

(3) The connection between pipes and valves and other equipment. In stainless steel piping systems, butterfly valves are generally used to connect pipes to each other. Although the butterfly valve is relatively compact in structure and beautiful in appearance when connected, its strength is not very high. Therefore, when calibrating stainless steel pipes, special attention should be paid to the distance between pipe flanges, so as to avoid excessive stress on the stainless steel pipes during use, causing butterfly valve rupture or stress corrosion. When performing local repairs on stainless steel pipes, if there are difficulties in disassembly and assembly due to the rigidity of the pipes, the disassembly and assembly range of the stainless steel pipes should be expanded to avoid forced local disassembly and assembly, which may cause the connection of the stainless steel pipes to be insufficiently tight. During the welding process in the field, flanges should be used for connection as much as possible. The use of flange connection can effectively avoid the problem that the stainless steel pipe cannot be passivated after being pushed against each other. In addition, it is worth noting that ordinary hands can be used to tighten stainless steel pipes, but direct collision between the wrench and the pipe must be avoided to avoid scratches and corrosion.

(4) Surface treatment of stainless steel pipes. When passivating stainless steel pipes, in addition to passivating the surface and interior, strict passivation treatment is also required for each weld of the pipe. Generally speaking, infields that process stainless steel pipes have no way to passivate the pipes themselves and need to send them to specialized manufacturers for passivation.

(5) Requirements for the processing area of stainless steel pipes. Stainless steel pipes have relatively high environmental requirements during processing and storage. This is mainly to prevent stainless steel pipes from being contaminated and corroded. Therefore, appropriate protective measures must be taken during the production process of stainless steel pipes. During the transportation of stainless steel pipes, lifting tools that can be covered must be used. During the transportation process, neither the iron rope nor the chuck should be in direct contact with the stainless steel to avoid being contaminated by iron and causing corrosion. When using stainless steel coffins, try to take them directly from the hanging basket and try not to place them on the ground. If the pipe must be placed on the ground, non-gold and black insulation material needs to be laid on the ground. Stainless steel pipes have inherent dyes during the storage process. They must be cleaned in time to keep the storage environment clean and dry.
