For stainless steel decorative tube and stainless steel industrial tube, although both are stainless steel tubes, but there are certain differences between the two, it goes without saying that there is a gap in the application field, and the use of the two determine the material, process, surface, etc.. Next, here will be a detailed understanding of what is the difference between stainless steel decorative pipe and stainless steel industrial pipe.
1.Material
Stainless steel decorative tube for indoor use, generally using 201 stainless steel and 304 stainless steel. Outdoor environment is harsh or coastal areas using 316 stainless steel, as long as the use of the environment is not easy to oxidation rust.
Stainless steel industrial pipe is mainly used for fluid transfer and heat exchange, etc., so the pipe corrosion resistance, high temperature resistance, pressure resistance, etc. have certain requirements, generally will choose 304 stainless steel, 316 stainless steel, 316L stainless steel; heat exchange pipe on the pipe fittings pay more attention to the high temperature resistance of the pipe fittings, generally choose good high temperature resistance 310s stainless steel, 321 stainless steel.
2.Production process
Stainless steel decorative tube is welded from steel strip; stainless steel industrial tube is cold rolled or cold drawn process, the raw material is round steel, is round steel after perforation into billet, and then the billet and then one after another cold rolled or cold drawn from.
3. Surface
Stainless steel decorative tube is generally bright tube, the surface of the normal matte surface or mirror state. In addition, the decorative tube also uses electroplating, baking paint, spraying and other processes, so that its surface color is bright. Stainless steel industrial tube surface is normally acid white surface that is pickled surface, because the tube is used in a more humid environment, high temperature, some objects have corrosive properties, so the higher requirements for antioxidation, pickling passivation can form a dense oxide film on the surface of the tube, greatly improving the corrosion resistance of the tube. A small amount of black skin tube, sometimes according to the need for surface polishing treatment, but the finishing effect can not be compared with the decorative tube.
4. Use
Stainless steel decorative tube, as the name implies, is for decoration, commonly used in balcony protection windows, stair handrails, bus stop handrails, bathroom drying racks, etc.; stainless steel industrial tubes are commonly used in industry, such as boilers, heat exchangers, mechanical spare parts, sewage pipes, etc.. But stainless steel industrial pipe wall thickness, pressure resistance are much higher than stainless steel decorative pipe, so a large number of pipelines used to transport fluids, such as water, gas, natural gas, oil, etc.
