PRODUCTS DETAILS

It is a kind of long steel with hollow section and no joint around. The thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing cost will rise substantially. The process of the product determines its limited performance. General seamless steel pipe has low precision: uneven wall thickness, low brightness on the inside surface, high cost of sizing, and the inner surface has pitting and black spots that are not easy to remove; Its detection and shaping must be handled offline. Therefore, it has its advantages in high pressure, high strength and material for mechanical structure.A. According to gb14975-2002 "Stainless Steel Seamless Steel Pipe", the steel pipe is usually 1.5 ~ 10m in length (variable feet), and the hot extruded steel pipe is equal to or greater than 1m. Cold-drawn (rolled) steel tube wall thickness of 0.5 ~ 1.0mm, 1.0 ~ 7m; Wall thickness greater than 1.0mm, 1.5 ~ 8m. B. Hot rolled (hot extrusion) steel pipe diameter 54 ~ 480mm altogether 45 kinds; There are 36 kinds of wall thickness 4.5 ~ 45mm. 65 kinds of cold-drawn (rolled) steel tubes with diameters of 6 ~ 200mm; There are 39 kinds of wall thickness between 0.5 and 21mm. C. There shall be no cracks, folds, cracks, crackles, lamination and scarring defects on the inner and outer surfaces of steel pipes. These defects shall be completely removed (except for pipes used for mechanical processing), and the wall thickness and outer diameter shall not exceed negative deviations after removal. Other minor surface defects that do not exceed allowable negative deviations may not be removed. D. The allowable depth of the straight. Hot-rolled and hot-extruded steel tubes, with diameters less than or equal to 140mm, no more than 5% of the nominal wall thickness, and the maximum depth no more than 0.5mm; Cold-drawn (rolled) steel tubes shall not be greater than 4% of nominal wall thickness, and the maximum depth shall not be greater than 0.3mm. E. Both ends of the steel pipe should be cut at right angles and burrs removed.With the implementation of China's reform and opening-up policy, the rapid growth of the national economy, urban housing, public buildings and tourism facilities built a large number of hot water supply and domestic water supply put forward new requirements. Especially the problem of water quality, people pay more and more attention to it, and the requirements are constantly improving. Galvanized steel pipe this common pipe because of its easy corrosion, under the influence of the relevant national policies, will gradually withdraw from the historical stage, plastic pipe, composite pipe and copper pipe became the common pipe pipeline system. But in many cases, stainless steel pipe is more advantageous, especially the thin-walled stainless steel pipe only 0.6 ~ 1.2mm in high quality drinking water system, hot water system and safety, health in the first place in the water supply system, with safe and reliable, health and environmental protection, economic application and other characteristics. It has been proved by domestic and foreign engineering practice that it is one of the best comprehensive performance of water supply system, new type, energy saving and environmental protection type pipe, and it is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and improving people's living standards. In the construction of water supply pipe system, because galvanized steel pipe has ended a hundred years of brilliant history, all kinds of new plastic pipe and compound pipe have been developed rapidly, but all kinds of pipe also have some deficiencies in different degrees, far can not completely adapt to the needs of water supply pipe system and the state of drinking water and water quality requirements. Accordingly, concerned expert foretells: building feed water material material will restore the age of metal tube eventually. According to the application experience abroad, thin wall stainless steel pipe is considered as one of the best pipe with comprehensive performance among metal pipes.
