Stainless steel seamless tube production process

　　Stainless steel welded pipe production process: raw materials - slitting - welding pipe - repair end - polishing - inspection (printing) - packaging - shipping (into the warehouse) (decorative welded pipe) Raw materials - slitting - welding pipe - heat treatment - straightening - straightening - repair end - pickling - hydrostatic pressure test - inspection (printing) - packaging - shipping (into the warehouse) (welded pipe industrial piping pipe)

　　Edit the application prospects of stainless steel pipe

　　Stainless steel pipe is safe, reliable, hygienic and environmentally friendly, economically applicable, thin-walled pipeline and the development of new reliable, simple and convenient connection methods successfully, so that it has more other pipe irreplaceable advantages, the project will be more and more applications, the use of more and more popularity, the prospect of a favourable outlook. With the implementation of China's reform and opening-up policy, the national economy to obtain rapid growth, urban housing, public buildings and tourism facilities built in large quantities, the hot water supply and domestic water supply has put forward new requirements. Especially the problem of water quality, people pay more and more attention to, and the requirements are constantly improving. Galvanised steel pipe this commonly used pipe because of its easy corrosive, under the influence of relevant national policies, will gradually withdraw from the stage of history, plastic pipe, composite pipe and copper pipe into the piping system commonly used pipe. But in many cases, stainless steel pipe is more superior, especially the wall thickness of only 0.6 ~ 1.2mm thin-walled stainless steel pipe in the high-quality drinking water system, hot water system and will be safe, hygiene in the first place to the water supply system, with safe, reliable, hygiene and environmental protection, affordable and so on. Has been proved by domestic and foreign engineering practice is a good water supply system comprehensive performance, new, energy-saving and environmentally friendly one of the pipe, but also a very competitive water supply pipe material, will improve water quality, improve people's living standards to play an unparalleled role. In the building water supply pipe system, as galvanised steel pipe has ended a century of glorious history, a variety of new plastic pipe and composite pipe has been the rapid development, but a variety of tubes are still varying degrees of some of the shortcomings, far from fully adapting to the needs of water supply pipe system and the country's drinking water and the quality of the water requirements. Therefore, the experts predicted: building water supply pipe materials will eventually return to the era of metal pipe. According to foreign application experience, in the metal pipe identified as thin-walled stainless steel pipe for the comprehensive performance of one of the pipe.

　　Domestic thin-walled stainless steel pipe to promote the application of time is ripe!

　　Thin-walled stainless steel pipe, domestic production in the late 1990s, the use of today's pipe field is the emergence of the newborn family, has been applied to a large number of building water supply and drinking water pipeline. Thin-walled stainless steel tube is durable, has been recognised by the engineering community, and the relevant parties are working to reduce the wall thickness, reduce the price, in order to facilitate further promotion. Especially small diameter stainless steel pipe, the price is not high, so supporting the connection method, the reliability of the fittings and price is the main factor determining its development. Domestic developers in Sichuan, Guangdong, Zhejiang, Jiangsu and other places have developed their own connection technology and fittings, is very promising pipe. The Ministry of Construction and relevant departments also attaches great importance to this new type of pipe, according to the Chinese technology market management and promotion centre, national science and city word [2001] No. 71 document, on the promotion and application of ‘high diameter and wall ratio of high-precision stainless steel pipe, high-pressure water supply and supporting pipe fittings and special technology’ in the notice was informed that the thin-walled stainless steel pipe this technology and product Promote the application of China's modern architecture to improve the grade, improve and protect the quality of water supply is of great significance. At the same time, the Ministry of Construction attaches great importance to the promotion and application of thin-walled stainless steel pipe. Thin-walled stainless steel water pipe’ industry standards have been released in 2001. Related pipeline engineering technical regulations and installation atlas, the Ministry of Construction has issued a document, is responsible for the preparation of Tongji University. At present, Sichuan, Guangdong, Zhejiang, Jiangsu and other places have professional manufacturers of thin-walled stainless steel pipe production, the product has become mature, and therefore, the time to promote the application has arrived.

　　Positive prospects for the domestic market

　?、?Building water supply pipe demand according to the ‘construction business’ Ninth Five-Year Plan and 2010 Visionary Goals Outline ‘estimates, 2001 ~ 2010, the annual demand for pipe for 50 ~ 60 million km, of which the demand for hot and cold water pipe in residential buildings for 400,000 km. It is believed that the development of stainless steel water pipe, to Improve the grade of modern urban buildings, is of great significance. ② Pipeline drinking water development rapidly with the development of the national economy, pipeline drinking water in the domestic Beijing, Shenzhen, Shanghai, Chongqing and other cities developing rapidly, economically developed medium-sized cities are also actively planning to catch up. In the direct drinking water, stainless steel pipe system is undoubtedly second to none. At present, the domestic upscale hotels, public places have been configured or in the configuration of the direct drinking water pipeline. Domestic replacement
