Stainless steel pipe fittings various processing methods

Sanitary fittings on the market is actually said to be stainless steel fittings, now as long as it is said to be sanitary fittings, that is certainly said to be stainless steel fittings, because the material is stainless steel.

Stainless steel is widely used mainly because of his good performance, high quality stainless steel should have good high temperature resistance, corrosion resistance, oxidation resistance, light weight and appearance. It is because of these very practical performance makes stainless steel is widely used in various industries.

Above the medical treatment of many medical devices are also used to make stainless steel. In the food industry is also, it can be said that stainless steel is spread in every corner of life. So since it is so extensive, then in the installation of which problems need to pay attention to? Because if the installation is not properly operated, it will directly affect his service life.

Six methods of stainless steel pipe fittings processing：

1. Roller method: the core is placed in the tube, the periphery is pushed with a roller for round edge processing.
2. Forging method: the end or part of the tube with a forging machine to be punched stretch, so that the outer diameter is reduced, commonly used type forging machine has a rotary, rod type, roller type.
3. Bending and forming method: there are three methods more commonly used, a method called stretching method, another method called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the fixed roller distance, the finished pipe fittings are bent.
4. Rolling method: generally do not use the mandrel, suitable for thick-walled pipe inside the round edge.
5. Drumming method: one is placed in the tube rubber, above the punch compression, so that the tube protrudes into shape; another method is the hydraulic drum forming, in the middle of the tube filled with liquid, liquid pressure to the tube drum into the desired shape, the production of corrugated pipe most of the use of this method .

Stainless steel pipe fittings in the transportation should be avoided with other metals in direct contact, can be wrapped up or with other non-metallic things to isolate. If the stainless steel pipe fittings to be welded, then in the positioning of the weld, the weld must be protected with argon gas, in the continuous welding, the whole process of temperature is maintained at about sixty degrees Celsius this way. Then to cut stainless steel pipe fittings, must use stainless steel pipe fittings special stainless steel cutting wheel or plasma cutting machine to cut. After the welding is completed, the weld should be passivated.
