Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, and economical. The thin-walled pipes and the successful development of new, reliable, simple and convenient connection methods have given them more irreplaceable advantages than other pipes, and their application in engineering will become more and more common. If there are more, the use will become more and more popular, and the prospects are promising.
Stainless steel seamless steel pipes are widely classified and used:
1. Stainless steel seamless steel pipe for structural use (GB/T8162-1999) is a seamless steel pipe used for general structures and mechanical structures.
2. Stainless steel seamless steel pipes for fluid transportation (GB/T8163-1999) are general seamless steel pipes suitable for transporting fluids such as water, oil, and gas.
3. Stainless steel seamless steel pipes for low and medium pressure boilers (GB3087-1999) are used to manufacture superheated steam pipes, boiling water pipes for low and medium pressure boilers of various structures, and superheated steam pipes, large smoke pipes, small smoke pipes and arches for locomotive boilers. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes for brick pipes.
4. Seamless steel pipes for high-pressure boilers (GB5310-1995) are high-quality carbon steel, alloy steel and stainless steel heating steel seamless steel pipes used for the heating surfaces of water tube boilers with high pressures and above.
5. Simple precision inner diameter seamless steel pipe for hydraulic and pneumatic cylinders (GB8713-88) is a cold-drawn or cold-rolled precision seamless steel pipe with precise inner diameter for manufacturing hydraulic and pneumatic cylinders.
6. Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-2000) is a cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment. Choosing Sichuan precision seamless steel pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and at the same time help improve product quality.
7. Stainless steel seamless steel pipe for structural use (GB/T14975-2002) is a hot-rolled ( Extruded, expanded) and cold drawn (rolled) seamless steel pipes.
Development prospects of stainless steel seamless pipes:
With the development of social economy and the rapid growth of the national economy, the construction of large numbers of urban residences, public buildings and tourist facilities has put forward new requirements for hot water supply and domestic water supply. Especially for water quality issues, people are paying more and more attention to them and their requirements are constantly improving. Due to its corrosive nature, galvanized steel pipes, a commonly used pipe material, will gradually withdraw from the stage of imitation under the influence of relevant policies of various countries. Material pipes, composite pipes and copper pipes have become common pipe materials in pipeline systems. But in many cases, stainless steel pipes have more advantages, especially thin-walled stainless steel pipes with a wall thickness of only 0.6~1.2mm in high-quality drinking water systems, hot water systems and water supply systems that put safety and hygiene first. , with the characteristics of safety, reliability, hygiene, environmental protection, economy and applicability. It has been proven by domestic and foreign engineering practices that it is a new, energy-saving and environmentally friendly pipe with the best comprehensive performance in the water supply system. It is also a very competitive water supply pipe and will surely play an incomparable role in improving water quality and improving people's living standards role.
