Stainless steel pipe for safety, hygiene and environmental protection, economy, thin-walled pipe and new reliable, simple and convenient connection method successfully, so it has more advantages of other pipe irreplaceable, engineering application will be more and more, will become more and more popular, promising.
Since stainless steel already has many desirable properties required by building materials, it is unique in metals and continues to develop. In order to make the stainless steel better in the traditional applications, has been on the improvement of the existing type, and, in order to meet the stringent requirements of high-level architectural applications, is the development of new stainless steel, due to constantly improve production efficiency, quality improvement, stainless steel has become one of the most cost-effective material selection of architects.
With the implementation of China's reform and opening-up policy, the national economy grows quickly, urban housing, public buildings and tourist facilities construction, put forward new requirements for the water supply and water supply, especially the water quality problems, people pay more and more attention. The requirements are also constantly improving.
Galvanized steel pipe, a common pipe, because of its corrosion resistance, under the influence of relevant national policies, will gradually withdraw from the stage of history, plastic pipes, composite pipes and copper pipe has become a common pipe system. But in many cases, more superior stainless steel tube, especially the wall thickness is 0.6 ~ 1.2mm of thin-wall stainless steel pipe in high quality drinking water system, hot water system and the safety and health in the first place of water system, which has the advantages of safety, hygiene and environmental protection and economical characteristics. Domestic and international engineering practice has been proved to be one of the best performance of the water supply system of pipes, new energy and environmental protection, and is also a very competitive water pipe, is bound to improve water quality, improve the living standards of the people to play the role of There is nothing comparable to this.
Water supply system in the building, because of galvanized steel over a hundred years of glorious history, a variety of new plastic pipe and composite pipe has gained rapid development, but also a variety of pipe in different degrees exist some shortage, far can not fully meet the water supply needs and the State Department of drinking water and the water quality requirements. Therefore, experts predict: building water supply pipe will eventually revert to the era of metal pipes.
Market prospect is promising
The development of piped drinking water is rapid
With the development of the national economy, direct drinking water in the pipeline has developed rapidly in cities such as Beijing, Shenzhen, Shanghai and Chongqing. The moderately developed cities in the developed areas are also actively planning to catch up with them. In the direct drinking water, the stainless steel pipe system is undoubtedly second to none. At present, domestic hotels and public places have been equipped with or equipped with direct drinking water pipes.
Domestic alternative import has a bright future
In order to promote the stainless steel tube, China since 1990s from the reduced wall thickness, reduce the cost to solve the "thinstainless steel high diameter wall high precision" tube technology, make the stainless steel pipe application development quickly. A pipeline can be fully popularized and applied, and domestic production is indispensable. Some domestic manufacturers have the ability to produce and develop thin-walled stainless steel pipes and fittings.
The main use of stainless steel exhaust system, accounting for more than 1/2 of the total amount of stainless steel car, 80% of ferritic stainless steel. The exhaust gas from the automobile engine flows through the exhaust manifold, front pipe, hose, converter, and central pipe and finally flows out of the muffler. Commonly used in the exhaust system are 409L, 436L and so on. Automobile muffler mainly uses stainless steel pipe. According to estimates, the use of stainless steel pipes in the car accounted for the entire downstream of the stainless steel pipe about 1.5% of the amount, while the use of stainless steel seamless tubes and welded pipe ratio of about 2:1.
Fluid transport such as water and gas
Stainless steel pipe and its water conveyance equipment is the most advanced basic water purifying material in the world. Its corrosion resistance is strong, and the cast iron pipe, carbon steel pipe, plastic pipe and so on can not compare with it.
Abroad frequently came to China's stainless steel casting products "double reverse" message, the China stainless steel casting industry has great influence, most of the development of China's export is a stainless steel industry, a strong market share in the industry's development, in the face of the economic downturn, the slowdown in the pace of development. Under the condition of the development of China's stainless steel industry should continuously improve product quality, to suppress the development of overseas trade and trade protectionism will be better, and the products of environmental protection, energy resources, combine the human environment to enhance the competitiveness of products, stainless steel, the only way to achieve the indefectible position in foreign trade.
