Cangzhou Bohai Steel Tube Co. elbow production and supply, quality and cheap. Stamping elbow, welding elbow (elbow butt) and so on. 16mn elbow steel elbow first selected sales specifications proposed pipe material, for example, of 90 ° bend, the curvature can be calculated by how long the material can be processed at a bend of 90 °, then the length of a given feet were cut off. Finally, the hot material pushing. Pushing machine is a horn-shaped core head or mandrel, the mandrel by a fine thicker, pushing process is a process of expanding with a curved, behind a support, the cutting mandrel steel elbow pipe penetration, behind There is a fixed mandrel arch frame, the middle of a car, car and some by hydraulic transmission, some by mechanical transmission that is screw drive, then push the car forward, pushing the car forward tube along the mandrel, the mandrel outer there is an induction coil, the tube is heated, well heated, and then push the car down the tube, it is a good process. After a good push, elbow to shaping under heat this state, because some elbow treated properly, will twist, which is not allowed. In addition, the outer diameter of the front pusher generally, to be shaped by plastic molding. Plastic mold is actually a press, to have a mold, two and a half arc, up and down each one. After shaping the outer diameter of the finished size is reached. Here we were finishing step after shot peening, the inner and outer surfaces of the oxide scale removal elbow to carry out the groove for the welding process ends. Then after checking, 16Mn alloy steel elbow hit the word, spray paint, and packaging processes, you can factory up. Cangzhou Bohai Pipe Co., Ltd. specializing in the production of alloy steel elbow API SPEC5CT-1999 (casing and tubing specification) 15CrMo alloy steel elbow, the American Petroleum Institute (American Petreleum Instiute, referred to as the 'API') prepared and published all over the world-wide . Where: Casing: from the ground surface into his inner drilling, as the wall lining pipe, connected by a coupling between its tubes. The main material for the J55, N80, P110 and other steel grade, as well as anti-hydrogen sulfide corrosion of C90, T95 and other steel grade. Its low grade (J55, N80) may be welded steel pipe. Tubing: from the ground surface of the insertion tube until the reservoir inner sleeve, or integrally connected by coupling between its tubes. Its role then pumping oil through the pipeline will transport oil to the surface. The main material for the J55, N80, P110, and anti-hydrogen sulfide corrosion of C90, the American Petroleum Institute prepared and published all over the world-wide. Sales alloy steel elbow, steel elbow, Ltd. Cangzhou Bohai Bohai Sea by Cangzhou tube. Cangzhou Bohai Tube Co., Ltd. (www.czbh628.com) (www.hbbh628.com) strong, credible, three-way, etc. Hebei Cangzhou accumulated a large number of loyal customers.
