Stainless steel pipe is 304 hollow, long, round steel, mainly used in 316 petroleum, mechanical instrumentation and other industrial transmission and welding pipeline and mechanical structural parts. At the same time, 316 in the precise bending and production with wall thickness and torsional strength of stainless steel pipe light weight. Therefore, it is also widely used in the manufacture of machine weights, mechanical parts and engineering structures, and is also commonly used in the production of conventional weapons of various thicknesses and artillery shells of various sizes.

304 stainless steel pipe can be divided into oil well pipe casing, oil pipe welding and drill pipe, welded pipe, size boiler tube, thickness mechanical structure tube, hydraulic branch welding column tube, 316l gas cylinder tube, 304 geological tube, precision chemical tube, high pressure fertilizer tube, oil cracking tube and ship thick ship tube. Stainless steel pipe is a seamless economic steel, is an important seamless product in the steel industry. It can be widely used by manufacturers for home decoration and industry. Many people in the market use sanitary grade material to manufacture stair railings, furniture, etc.

There are 201 and 304 manufacturers. 25% of the specifications can be reliably used in industries such as oil, boiler, pipe welding, aerospace, 316 nuclear power, and the manufacture of thick-walled large equipment. About 60% of the general pressure vessel manufacturing can be used in the food, urban environmental protection and other production industries, and about 20% of 316 products are not qualified or available. Electronics, metallurgy and other industries require stainless steel piping sanitary grade of about every 5,000 tons. Thick-walled used in light industry and printing and dyeing and other medical and pharmaceutical industries for the manufacture and maintenance of equipment, the annual consumption of stainless steel pipe more than 20,000 tons.
