Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
Application prospects of stainless steel pipes
Stainless steel pipe is a kind of economical cross-section steel. It is an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people on the market use it to make stair railings, window guards, railings, furniture, etc. There are two common materials, 201 and 304.
It accounts for about 8% to 16% of the total amount of steel, and it has a wide range of applications in the national economy. Because the steel pipe has a hollow section, it is most suitable as a pipeline for liquid, gas and solid transportation. At the same time, compared with round steel of the same weight, the steel pipe has a large section coefficient and high bending and torsion strength, so it has become a variety of machinery and building structures. Important material on the site. Structures and parts made of stainless steel tubes have a larger section modulus than solid parts under the same weight. Therefore, stainless steel pipe itself is a kind of economical section steel that saves metal. It is an important part of high-efficiency steel, especially in oil drilling, smelting and transportation industries. The second is geological drilling, chemical industry, construction industry, machinery Industry, aircraft and automobile manufacturing, as well as boiler, medical equipment, furniture and bicycle manufacturing also require large amounts of various steel pipes. With the development of new technologies such as atomic energy, rockets, missiles, and aerospace industries, stainless steel pipes have become more and more important in the defense industry, science and technology, and economic construction.
Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipes and the successful development of new reliable, simple and convenient connection methods make it have more irreplaceable advantages for other pipes, and more and more applications in engineering , Use will become more and more popular, and the prospects are promising.
As stainless steel has many ideal properties required by building materials, it can be said to be unique among metals, and its development continues. In order to make stainless steel perform better in traditional applications, the existing types have been improved, and in order to meet the strict requirements of advanced construction applications, new stainless steels are being developed. Due to continuous improvement in production efficiency and continuous improvement in quality, stainless steel has become one of the most cost-effective materials chosen by architects.
Stainless steel combines performance, appearance and use characteristics, so stainless steel will still be one of the best building materials in the world.
Application need of stainless steel pipe
Stainless steel is mainly used in the exhaust system, which accounts for more than 1/2 of the total amount of automotive stainless steel, and 80% is ferritic stainless steel. The exhaust gas generated by the automobile engine finally flows out of the muffler through the exhaust gas intake pipe, front pipe, hose, converter, and center pipe. Commonly used steel grades for exhaust systems are 409L, 436L, etc. Automobile mufflers mainly use stainless steel welded pipes. According to calculations, stainless steel pipes used in automobiles account for about 1.5% of the entire downstream consumption of stainless steel pipes, and the use ratio of stainless steel seamless pipes and welded pipes is about 2:1.
The petrochemical industry includes the fertilizer industry
There is a huge demand for stainless steel pipes. The industry mainly uses stainless steel seamless pipes. The specifications include: 304, 321, 316, 316L, 347, 317L, etc. The outer diameter is about ￠18-￠610, and the wall thickness is 6mm-50mm Around (usually select medium and low pressure conveying pipes with specifications above Φ159mm), the specific application areas are: furnace pipes, material conveying pipes, heat exchanger pipes, etc.
Transportation of fluids such as water and gas
Stainless steel pipes and their water delivery equipment are the most advanced basic water purification materials in the world today. They have strong anti-corrosion performance. Cast iron pipes, carbon steel pipes, plastic pipes, etc. cannot be compared with them.
The best choice for water industry such as water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand is about 25,000 tons.
Equipment manufacturing and maintenance
The annual consumption of stainless steel pipe is more than 20,000 tons. This type of industry mainly uses sanitary or antibacterial grade stainless steel pipes. The sanitary seamless pipe made of imported SUS304 and 316L can meet the special requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial performance. The demand for kitchen equipment, workbenches and utensils in the food industry, medical equipment, tableware and towel holders in daily life, and brackets for refrigerated cabinets is increasing.
