Sanitary Valve is used in food, storage, transportation and medical industries. The material of sanitary stainless steel pipe is made of stainless steel. According to the classification, it can be divided into sanitary stainless steel seamless pipe, sanitary welded pipe and cold-rolled precision stainless steel pipe. Sanitary pipe fittings have different uses and different welding properties. Some tableware does not require welding performance, including some canning companies. However, most products require good raw material welding performance, such as second-class tableware, thermos bottles, steel pipes, water heaters, water dispensers, etc.

Thin-walled sanitary stainless steel pipe parts have poor rigidity and weak strength, and are easily deformed during processing, which increases the shape and position errors of parts, and it is difficult to ensure the processing quality of parts. Strict requirements are put forward for clamping ultra-thin-wall sanitary pipe fittings, reasonably selecting turning tools and selecting cutting amounts. The processed ultra-thin-wall sanitary pipe is a heat-resistant shock sleeve for product nozzles.

The workpiece belongs to a large-diameter ultra-thin-wall sanitary stainless steel pipe, the outer diameter of the pipe is 292mm, the material Z2CND17-12 is controlled by nitrogen, the wall thickness is 4mm, the total length of the workpiece is greater than 550mm (remaining margin), and the roundness is 0.05mm. The total surface roughness value Ra=6.3μm determines that the accuracy coefficient of the workpiece is very high.

Many stainless steel sanitary accessories have good corrosion resistance in food, for example, Class I and Class II tableware, kitchen utensils, water heaters, water dispensers, etc. Many foreign merchants have tested the corrosion resistance of sanitary accessories: NACL aqueous solution is heated to boiling, the solution is poured out for a period of time, sucked clean and dried, and then weighed to determine the degree of corrosion.
