For stainless steel decorative pipes and stainless steel industrial pipes, although both are stainless steel pipes, there are certain differences between the two. It goes without saying that there is a gap in the application field, and the use determines the material, process, and Surface etc. In the next step, Shenlong Pipeline will learn more about the difference between stainless steel decorative pipe and stainless steel industrial pipe?

1. Material

---

Stainless steel decorative pipes for indoor use generally use 201 stainless steel and 304 stainless steel. 316 stainless steel is used in harsh outdoor environments or coastal areas, as long as the environment is not easy to oxidize and rust.
Stainless steel industrial pipes are mainly used for fluid transportation and heat exchange. Therefore, there are certain requirements for the corrosion resistance, high temperature resistance, and pressure resistance of the pipe. Generally, 304 stainless steel, 316 stainless steel, and 316L stainless steel are used; Pipe fittings pay more attention to the high temperature resistance of pipe fittings. Generally, 310s stainless steel and 321 stainless steel with good high temperature resistance are selected.

2. Production process

---

Stainless steel decorative pipes are welded by steel strips; stainless steel industrial pipes are cold rolled or cold drawn. The raw material is round steel. The round steel is pierced into a tube blank, and then the tube blank is cold rolled or cold drawn one after another Become.

3. Surface

---

Stainless steel decorative tubes are generally bright tubes, and their surface is normally matt or mirrored. In addition, the decorative tube also uses electroplating, baking paint, spraying and other processes to make its surface bright. The surface of the stainless steel industrial pipe is normally acid white surface, that is, the acid-washed surface. Because the pipe is used in a humid environment and high temperature, some objects have corrosive properties, so the anti-oxidation requirements are high. Pickling passivation can form a dense oxide film on the surface of the pipe. , Greatly improve the corrosion resistance of the pipe. For a small amount of black leather pipes, the surface is sometimes polished as needed, but the finishing effect cannot be compared with that of decorative pipes.

4. Purpose

---

Stainless steel decorative pipes, as the name suggests, are used for decoration. They are often used for balcony protective windows, stair handrails, bus station handrails, bathroom drying racks, etc.; stainless steel industrial pipes are often used in industries, such as boilers, heat exchangers, mechanical parts, sewage pipes, etc. However, the wall thickness and pressure resistance of stainless steel industrial pipes are much higher than those of stainless steel decorative pipes, so they are widely used in pipelines for conveying fluids, such as water, gas, natural gas, and oil.
