Sanitary pipe surface polishing commonly used processing methods
Sanitary pipe surface is very smooth, very bright, not from the manufacturers to produce such a way, which have to be polished to become so good processing. So the surface of sanitary pipe fittings commonly used polishing method which? we make a simple introduction:
1, health-grade stainless steel tube bending method: There are three methods are more commonly used, a method called extension method, another method called stamping method, the third roller method, 3-4 rollers, two fixed roller, a Adjust the roller, adjust the fixed roller from the finished pipe is bent.
2, health-grade stainless steel tube bulging method: one is placed in the tube rubber, the top with the red sub-compression, the tube protruding forming; Another method is the hydraulic bulging forming, filling the tube in the middle of the liquid, the liquid pressure tube drum Into the desired shape, most of the bellows production is using this method.
3, forging method: the end of the pipe or part of the forging machine to red stretch, so that health-grade stainless steel pipe diameter to reduce the commonly used forging machine with rotary, connecting rod, roller type.
4, stamping method: in the punch with a taper of the health-grade stainless steel pipe fittings to expand to the required size and shape.
5, the roller method: placed in the tube core, the outer wheel with a push, for the round edge processing.
6, rolling method: generally do not have mandrel, suitable for thick-walled tube inside the circle.Health-grade pipe fittings industry to go for a better development of light space.
In recent years, people focus on the food hygiene to the above, which is invisible to the sanitary pipe fittings industry has brought tremendous pressure for sanitary pipe fittings enterprises, in the food processing industry downstream, should pay attention. The development of the industry, the competition is constantly expanding, as a modern society, is an era of information explosion, enterprise products in the face of competitors are inevitable, I believe that companies compete for consumers, but also A good thing. Because of competition, companies will enhance the quality, consumers can spend the least money to get more concessions.
During the second five-year period, Chinese sanitary valve fittings industry to implement industrial development trends, in accordance with resource-saving and environment-friendly society's development. Coupled with Chinese expanding market resources, oil, chemicals, electricity, especially health-pipe fittings industry continues to expand the development needs of butterfly valve in late October trading volume is relatively sluggish, only 19% of the market share in third place. Some backward production capacity to be eliminated, health-grade pipe fittings industry to go for a better development space.
