Coiled Tubing Manufacturing Technology
Coiled tubing is a single length of several kilometers and repeated bending, achieve multiple plastic deformation of the new oil pipe. Coiled tubing equipment and its operation is called “universal working machine” in the foreign countries such as the United States, Canada and other c...Read more -
High-frequency Welded Pipe on the Quality of the Welding Operation in Process
Welding pressure Frequency welded pipe welding pressure is one of the main parameters of the welding process, after the two edges of the tube is heated to welding temperature and squeezing produce welded under pressure to form a common metal grain that is mutually crystals. Since the tube width a...Read more -
Structural Steel Heat Treatment Technology
Structural steel workpiece in the heating and cooling process, due to inconsistencies cooling rate of the surface layer and the core section and time form a temperature difference, it will lead to volume expansion and contraction of the uneven stress that the heat stress. In the thermal stress du...Read more -
The Main Method of Straight Welded Steel Pipe
Forged: forging hammer use reciprocating impact force or press pressure so we need to change the blank shape and size of a pressure processing method. Extrusion: steel metal is placed in closed extrusion Jane, put pressure on one end of the metal from the die orifice to obtain a predetermined ext...Read more -
The Main Production Process of High-pressure Pipe
The main production process of high-pressure pipe: billet heating, perforated tube, pipe extension. High-pressure pipe rolling, pipe sizing and reducing, finishing and cooling pipe or the manufacturing method can be said Billet heating perforation heat tie pickling cold drawn carbon burning cutti...Read more -
Large-caliber Straight Seam Steel Pipe Production Process
1. Before molding work Raw materials that strip, wire, flux. We must go through rigorous physical and chemical testing before it is put. Strip head and tail docking, single or double wire submerged arc welding, in rolled steel by automatic submerged arc welding. 2. The molding process Electric co...Read more
