Virtues produce diameter steel pipe factory 10mm-377mm, wall thickness of 6mm-50mm seamless steel pipe. Cold rolled precision light tube 20mm-95mm thickness of 6mm-20mm bearing steel alloy pipe wall thickness of 20mm-377mm outside diameter of 5mm-50mm sales 6mm-820mm, wall thickness of 1mm-70mm and other specifications of seamless steel tubes; material: 20 # , 45 #, 16Mn, 27SiMn, 15CrMo, 35CrMo.12CrlMoV, J55, K55, N80, etc; the implementation of standards: GB8162-1999, GB8163-1999, GB3087-1999, GB5310-1995, GB6479-2000, ASTMA53, A106, API 5L / 5CT, DIN, JIS and so seamless. Our products are widely used in petroleum, chemical, power, coal, machinery, high pressure boiler tubes, hydraulic prop, shipbuilding and other industries, and take advantage of the right to export advantage, into the international market. Have been exported to South Korea, Canada, Iran, Italy, Brazil, the United Arab Emirates, Pakistan, Nigeria, India and other countries and regions. High-precision cold drawn precision cold drawn steel tube characteristics has the following characteristics: (1) high production efficiency: the traditional method of producing a 420 mm inner diameter, 12 m long cylinder need 154 hours, produced by cold drawing only 4 minutes. (2) Genuine rate: As boring rolling head and play the leading role in the cutting process, the blank tube produces deflection due to its own weight, causing rolling head and boring tool easy road, resulting in waste. Genuine rate can only reach about 60%, while the production honing cylinder with cold drawn tube method, genuine rate of 95%. (3) metal utilization is high: the traditional method of manufacturing a cylinder bore, metal utilization rate of only 50-70%. When using the drawing process for the production of metal being cut into not only the end of honing iron pipe, but you can get 30% of the extension, the metal utilization rate of 95%. (4) can improve the mechanical properties of the finished metal tube: produced by drawing, so that the blank to obtain more than 30% of plastic deformation, due to the strength of the finished pipe leaving the work hardening of metal limits greatly improved. Generally in the finished tube inner strength limit by up to 60 percent. High-precision cold drawn seamless hot-rolled steel pipe is, Longitudinal for billets, after chemical treatment on a dedicated drawing machine quilting thick tube mill, deformed by special mold design principles drawn Shandong honing tube production high precision tube. Its size accuracy of H10 ~ H8, straightness up 0.35 ~ 0.5mm / m, the surface roughness of Ra1.6-0.4. Thick-walled tube honing _ virtue of Industry (certified) _ honing tube is provided by virtue of Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd.
