Among stainless steel products, stainless steel pipes are widely used in various industries because of their good ductility. As a hollow long cylindrical steel, stainless steel pipe is used as a pipeline for conveying fluid, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.
Stainless steel pipes are mainly divided into two basic categories: seamless stainless steel pipes and welded stainless steel pipes (referred to as welded pipes). The main difference between the two is whether there is a weld on the inner wall of the pipe.

Stainless steel seamless pipe
Stainless steel seamless steel pipe, like its name, has no weld seam. When it is made, it uses round tube billet as raw material for perforation, and is made by cold rolling, cold drawing or hot extrusion production process. There are no solder joints.
Stainless Steel Welded Pipe
The stainless steel welded pipe is welded by steel plate or steel strip after being crimped and formed by the unit and the mold. There is generally a weld on the inner wall of the pipe.

The smoothness of the inner wall of the stainless steel decorative pipe is good, which avoids the occurrence of impurity condensation. It is the most ideal material for construction. If the inner wall of the pipe fittings produced by cold-rolled coils is smooth, it can reach the industrial mirror level, and the flow resistance of stainless steel pipe fittings at low flow rates The coefficient is 2/5 of the carbon steel pipe, which reduces the transportation cost.
The temperature resistance of stainless steel decorative pipe is very good. Some pipes will precipitate harmful substances at 40 degrees, and produce peculiar smell. Some pipes corrode very fast on the inner wall at a certain temperature, which shortens the service life of the pipe fittings, and stainless steel can be used at minus 270 degrees to 400 degrees. It can work safely for a long time at a certain temperature, and its performance is very stable.
Stainless steel pipe application
Stainless steel decorative tubes have high tensile strength.
The stainless steel decorative tube has excellent wear resistance. If the pipe fittings are easily eroded by the water flow, it will become a killer of human health. Stainless steel fittings can withstand operating in fluid environments up to 20 m/s.
Stainless steel decorative pipe tonization effect is very unique. The pH value in water, air, dissolved oxygen, impurities, water treatment agents, etc. can cause corrosion of pipe fittings. The stainless steel pipe fittings have a thin and dense oxide film, and its function is to react with the oxidizing agent, thus preventing the further occurrence of the oxidation reaction. And other metal pipes have almost no such function of tonization.
