Stainless steel pipe is an economical section steel, and it is an important product in the steel industry. It can be widely used in life decoration and industry. Many people on the market are used to make stair handrails, window guards, railings, furniture and so on. The common materials are 201 and 304.

 

It accounts for about 8% to 116% of the total steel products, and it is widely used in the national economy. Because of its hollow section, steel pipes are most suitable for liquid, gas and solid pipelines. At the same time, compared with round steel with the same weight, steel pipes have large cross-section coefficient and high flexural and torsional strength, so they have become important materials in various mechanical and architectural structures. Structures and components made of stainless steel pipe have larger section modulus than solid parts under the condition of equal weight. Therefore, stainless steel pipe itself is a kind of economical section steel which saves metal. It is an important component of high-efficiency steel, especially in oil drilling, smelting and transportation industries. Secondly, geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing, as well as boiler, medical equipment, furniture and bicycle manufacturing also need a lot. All kinds of steel pipes. With the development of new technologies such as atomic energy, rocket, missile and aerospace industry, stainless steel tube plays an increasingly important role in national defense industry, science and technology and economic construction.

 

Stainless steel pipes are safe, reliable, sanitary, environmentally friendly, economical and applicable. The successful development of thin-walled pipes and new reliable, simple and convenient connection methods makes them have more irreplaceable advantages than other pipes. The application of stainless steel pipes in engineering will be more and more popular, and the prospect is promising.

 

Because stainless steel has many ideal properties required by building materials, it can be said to be unique in metals, and its development is continuing. In order to improve the performance of stainless steel in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the stringent requirements of advanced building applications. With the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials chosen by architects.

 

Stainless steel combines performance, appearance and service characteristics, so stainless steel will still be one of the best building materials in the world.

 

With the implementation of China's reform and opening-up policy, the national economy has been growing rapidly, and a large number of urban residential buildings, public buildings and tourist facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. Especially the problem of water quality, people pay more and more attention to it, and the requirements are constantly improving. Galvanized steel pipes, which are commonly used in pipeline systems, will gradually withdraw from the historical stage due to their corrosion resistance under the influence of relevant national policies. Plastic pipes, composite pipes and copper pipes have become common pipes in pipeline systems. But in many cases, stainless steel pipes have more advantages, especially thin-walled stainless steel pipes whose wall thickness is only 0.6-1.2 mm have the characteristics of safety, reliability, sanitation, environmental protection, economy and applicability in high-quality drinking water system, hot water system and water supply system which put safety and sanitation first. It has been proved by engineering practice at home and abroad that it is one of the pipes with the best comprehensive performance, new type, energy saving and environmental protection. It is also a very competitive water supply pipe material. It will play an incomparable role in improving water quality and people's living standards.

 

In building water supply pipeline system, because galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have been developed rapidly, but there are still some shortcomings in various pipes to varying degrees, which are far from fully adapted to the needs of water supply pipeline system and the requirements of the state for drinking water and related water quality. Therefore, experts predict that building water supply pipe materials will eventually return to the era of metal pipe. According to the application experience of foreign countries, thin-walled stainless steel pipes are considered as one of the best comprehensive properties in metal pipes.
