The Shandong Liaocheng Fu Kun Steel Pipe Co., Ltd. Tel :0635 -87,020,768,702,078 Mobile: 18865273166 13626358826 Fax 0635 -8702067 Manager: Wang QQ: 56,980,253 Website: http://www.si-bin.com Address: Liaocheng, Shandong Economic Development Changjiang Road and Airport Road Interchange NO.7777 the Beijing cold rolled precision steel pipe: cold drawn or cold rolled precision seamless steel pipe (GB3639-83) for the mechanical structure, hydraulic equipment, high dimensional accuracy and surface finish of cold drawn or cold rolled precision seamless steel tubes. Selection of precision seamless steel pipe manufacturing mechanical or hydraulic equipment, can be btrwe big big savings machining working hours, improve material utilization, and at the same time help to improve the quality of products. Beijing rolled precision steel is a high precision in the treatment of a cold drawn or cold rolled steel pipe material. Beijing rolled precision steel pipe inside and outside wall oxide layer to withstand high-pressure leak-free, high-precision, high-quality finish, cold-formed deformation, flaring, flattening cracks btrwe bit, so mainly used for the production of pneumatic or hydraulic components , such as the cylinder or cylinders, may be a seamless tube, welded pipe (after the cold rolling process). Beijing chemical rolled precision steel main component iron Fe carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, Chromium Cr ... Rolled precision steel pipe production process: tube - Inspection - Skinning - test - heating - perforation - pickling - grinding - lubricated air dry - welding head - cold drawn - solution treatment - Pickling - Pickling the passivation - NTYHY inspection, - cold - to oil - cut head - air-dry - polishing - outside polishing - Inspection - logo - finished packaging Beijing cold rolled precision steel tube and pipe joints distinction without btrwe seamless steel pipe main features is the welding seam, can withstand greater pressure. Products can be very rough cast or cold reversal pieces. 2, the Beijing cold rolled precision steel pipe products emerged in recent years, mainly within the hole, the outer wall of the tight tolerances and roughness size. Rolled precision steel cold rolling cold rolled precision steel pipe Usage: cold rolled precision steel pipe seamless steel tubes for precision mechanical structure, hydraulic equipment or reinforced sleeve high dimensional accuracy and surface finish of a good one without pipe joints. Company with a good reputation, high quality products, strong strength, the low price btrwe national reputation in more than 30 provinces, municipalities, autonomous regions, municipalities directly under the Central Government, the product won users rely. Perennial with a stock of more than 2,000 tons of alloy tube. Has been the formation of more than 4,000 tons of annual inventory turnover, more than 600 kinds of specifications. Cutting flanges and special parts according to user requirements, processing of finished or semi-finished products for delivery and arrange transportation for clients.
