Baotou fluid tubes stock: fluid tube is a hollow cross-section, from beginning to end without weld pipe. The ring with a steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time acid phosphate seamless steel tubes, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material, barrel, barrel, etc. to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. Because in the perimeter of equal conditions, the largest area of ??a circle phosphide seamless steel tubes, with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the phosphate processing seamless steel tubes, the vast majority of pipe is pipe Liaocheng virtue Pipe Industry Co., year round to maintain inventory of about 60,000 tons , materials are: 20 #, 45 #, 20G, 16Mn, 27SiMn, 12CrMo, 15CrMo; execution GB for: GB8162-2008 (structural pipe), GB8163-2008 (fluid pipe), GB3087-2008 (low pressure boiler tubes) , GB5310-2008 (high-pressure boiler tubes), GB9948-88 (petroleum cracking tubes), GB6479-2000 (fertilizer tube) 304,304L, 316,316L, 310,310S, 321 stainless steel plate, stainless steel tube. 15CrMoG seamless steel pipe seamless steel 15CrMoG recyclable, environmentally friendly, energy saving, national strategies, national policy of saving resources to encourage the expansion of applications 15CrMoG seamless steel pipe. Half, 15CrMoG areas currently use our seamless steel pipe seamless steel 15CrMoG total steel consumption accounts only for the developed countries to expand the proportion of providing a broader space for development of the industry. 1. seamless steel pipe for its manufacturing process is different, is divided into hot-rolled (extrusion) two kinds of seamless steel tubes and cold drawn seamless steel (rolled). Cold drawn (rolled) pipe is divided into two kinds of circular pipe and shaped pipe. 2 a. Process Overview of hot-rolled (extruded seamless pipe): round tube → heating → perforation → three-roll rolling, rolling or extrusion → → set off pipe diameter (or reducing) → cooling → → straightening pipe billet → hydrostatic test (or testing) → mark → storage. Cold drawn (rolled) seamless steel pipe: round tube → heating → perforation → Heading → annealing → pickling → oiled (copper) → multi-pass cold drawn (cold) → billet tube heat treatment → → straightening → hydrostatic testing (testing) → mark → storage seamless steel pickling | virtues of Industry (certified) | Jining seamless steel pipe industry by virtue of Liaocheng Limited.
