Stainless steel pipe is an economical section steel. It is an important product in the iron and steel industry. It can be widely used in living decoration and industry. Common materials are 201 and 304.
It accounts for about 8% to 16% of the total steel. It has a very wide range of applications in the national economy. Due to its hollow section, steel pipes are most suitable for liquid, gas, and solid transportation pipelines. At the same time, compared with round steel of the same weight, the steel pipe has a large section coefficient and high bending and torsional strength, so it has become a variety of mechanical and building structures Important material. Structures and components made of stainless steel tubes have a larger section modulus than solid parts with equal weight. Therefore, stainless steel pipe itself is a kind of economical steel with economical section. It is an important component of high-efficiency steel, especially in petroleum drilling, smelting and transportation industries. Secondly, geological drilling, chemical industry, construction industry, machinery Industry, aircraft and automobile manufacturing as well as boilers, medical equipment, furniture and bicycle manufacturing also require a large variety of steel pipes. With the development of new technologies such as atomic energy, rockets, missiles and the aerospace industry, stainless steel tubes 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, and economically applicable. The thinning of the pipes and the development of new reliable, simple and convenient connection methods have made them more irreplaceable advantages of other pipes, and they will be used more and more in engineering. , The use will become more and more popular, the prospects are promising.
Because stainless steel already has many of the desirable properties required for 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. As production efficiency continues to improve and quality continues to improve, stainless steel has become one of the most cost-effective materials of choice for architects.
Stainless steel combines performance, appearance and use characteristics, so stainless steel will still be one of the best construction materials in the world.
With the implementation of China's reform and opening-up policy, the national economy has grown rapidly, and a large number of residential buildings, public buildings and tourism facilities have been constructed, which has set new requirements for hot water supply and domestic water supply. Especially with regard to water quality issues, people are paying more and more attention, and requirements are constantly increasing. Due to its corrosive nature, galvanized steel pipes will gradually withdraw from the historical stage under the influence of relevant national policies. Plastic pipes, composite pipes and copper pipes have become common pipes in pipeline systems. However, in many cases, stainless steel pipes are more superior, especially thin-walled stainless steel pipes with a wall thickness of only 0.6 to 1.2 mm. In high-quality drinking water systems, hot water systems, and water supply systems that place safety and hygiene first, they have Safety and reliability, health and environmental protection, economical and applicable features. It has been proved by domestic and foreign engineering practices that it is one of the newest, energy-saving and environmentally friendly pipes with the best comprehensive performance of the water supply system. It is also a very competitive water supply pipe, which will definitely play a role in improving water quality and improving people's living standards. Comparable role.
In the building water supply pipe system, as the galvanized steel pipe has ended a century of glorious history, various new plastic pipes and composite pipes have developed rapidly. However, there are still some shortcomings in various pipe materials, which are far from fully adaptable to water supply pipes. System needs and national requirements for drinking water and related water quality. Therefore, relevant experts predict that the building water supply pipe will eventually return to the era of metal pipes. According to foreign application experience, thin-walled stainless steel pipe is identified as one of the best comprehensive performance among metal pipes.
