Stainless steel welded pipe

Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made of commonly used steel or steel strips after being crimped and formed by a unit and a mold. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipes.

Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the advancement of welding and inspection technology, the quality of welds has been continuously improved, and the varieties and specifications of welded steel pipes have been increasing. Heat exchange equipment has replaced seamless steel pipes with pipes, decorative pipes, medium and low pressure fluid pipes, etc.
The use of stainless steel welded pipe
Stainless steel welded pipe is this kind of hollow strip-shaped annular stainless steel plate, which is mainly used for industrial production of gas pipelines and their mechanical structural components in crude oil, chemical plants, diagnosis and treatment, food, light industry, mechanical equipment instrument panels, etc. Nowadays, it is also widely used in decoration engineering, furniture making, landscape engineering and other projects.
The advantages of stainless steel welded pipe
1. Stainless steel decorative pipes are also in great demand for making furniture, because stainless steel has strong corrosion resistance and oxidation resistance. It is also very convenient and simple to clean, and its service life is much longer than that of wooden and iron furniture.
2. Stainless steel pipes are also used in conjunction with glass, marble and other materials when making furniture. There will also be bending for modeling, which is also very demanding in welding technology. Only a good stainless steel pipe can make stainless steel furniture with novel style and unique shape.
3. The advantage of the stair handrail made of stainless steel decorative pipe is that the surface is smooth and free of burrs, which is generous and simple and not easy to change color.
4. Stainless steel screen is a decorative product that has been gradually used indoors in recent years. The screens made of stainless steel decorative tubes are very good in various mechanical properties, high hardness, good toughness, rust and corrosion resistance, and are quite reassuring in ordinary use environments.
Stainless steel welded pipe decoration
1. If the stainless steel decorative pipe is used indoors, it is generally made of 201 and 304 stainless steel. In the harsh outdoor environment or in coastal areas, 316 material is used, as long as the environment used is not easy to cause oxidation and rust; industrial pipes are mainly used for fluid transportation. , heat exchange, etc., so the pipes have certain requirements for corrosion resistance, high temperature resistance, and pressure resistance. Generally, 304, 316, 316L corrosion-resistant 300 series stainless steel materials are used;
2. The stainless steel decorative pipe is normally a bright pipe, and the surface is normally matte or mirror. In addition, the decorative pipe also uses electroplating, baking paint, spraying and other processes to coat its surface with a brighter color; the surface of the industrial pipe is normally acid. The white surface is the pickling surface, the surface requirements are not strict, the wall thickness is uneven, the brightness of the inner and outer surfaces of the tube is low, the fixed size cost is high, and the inner and outer surfaces should have pitting and black spots, which are not easy to remove.
3. Stainless steel decorative pipes are used for decoration as the name implies, and are normally used for balcony protective windows, stair handrails, bus station handrails, bathroom drying racks, etc.; industrial pipes are normally used in industries, such as boilers, heat exchangers, mechanical parts, sewage pipes, etc. . However, because its thickness and pressure resistance are much higher than those of decorative pipes, a large number of pipes are used to transport fluids, such as water, gas, natural gas, and oil.
