Use Stainless steel pipes's main three uses:
1. stainless steel decorative pipe
In fact, it is used as a decorative stainless steel pipe, mainly divided into 201,304 and 316 pipes, mainly in stainless steel anti-theft windows, stair guardrail, stair handrails and other widely used. According to the types, decorative tube can also be divided into ordinary tube, flower tube, color tube and so on.
Stainless steel ordinary pipe features: simple production process, specifications;
Stainless steel flower tube features: Stainless steel flower tube is upgraded above stainless steel ordinary tube, to make it more beautiful.
Stainless steel color tube features: Stainless steel color tube surface is coated with a layer of bright color coating, any specifications can be added to the ordinary pipe on the corresponding processing method.
2. stainless steel industrial pipe
Divided into seamless pipe and welded pipe.
Production process: Most of them are welded tubes, welded by stainless steel coil and electric welding, and inserted into a certain thickness of the sheet after hot melting, and then injected the required sheet. The tube cavity is decorated with stainless steel plate. Stainless steel seamless pipe is produced by cold drawing process, and the pipe wall is seamless.
Pipe surface: The welded pipe is a stainless steel pipe made by rolling processing, and the pipe surface is smooth and polishing. The surface of industrial seamless pipes is generally rough.
Thickness difference: 304 stainless steel decorative pipe thickness is thinner, about 0.2mm~5.0mm, and industrial seamless pipe is generally thicker.
Application: Because the stainless steel welded pipe is thin and the surface treatment effect is good, it is mostly used in architectural decoration products, civil decorative art stainless steel products and so on. The wall of stainless steel industrial pipe is thick and the surface is not smooth, the bearing capacity is strong, and it is mostly used for making large size, high strength, high toughness, mechanical systems and other products.
3. stainless steel products pipe
In general, stainless steel products pipe refers to the stainless steel pipe specially customized by the stainless steel pipe manufacturer, because the ordinary stainless steel decorative pipe does not meet its use requirements. Generally according to the different needs of users, a variety of optimization design methods are adopted. For example, stainless steel furniture pipe, sanitary ware pipe and so on. Pipes need high workmanship requirements, generally have specific pipe diameter, bending, flaring, shrinking, bending and other requirements.
