Cold Drawn Tube or Cold Rolling Precision Seamless Tube (gb3639-2000) is used for mechanical structure pipe, hydraulic oil cylinder and equipment, with high precision and fine surface finish of cold drawing or cold rolled precision seamless steel tube.
Cold Drawn Steel Tube, cold rolled steel pipe unit is made of cold rolled, cold drawn or cold rolled and cold drawn pipe cold working methods of combining production of a complete set of gear combinations, the capillary billet or raw material tube expanding process of cold drawing for zhongtong too much processed is of deep processing of hot rolled steel tubes or welded pipe units. Cold drawn pipe: (1) the basic process pipe material used for hot rolling and rolling tube, (2) tube material inspection, pickling, phosphating, saponification (3) the cold drawing process to the specified inside diameter size (4) finished finishing: including the finished heat treatment, straightening, sampling, cutting head to tail, check (manual inspection and various testing), oil, packaging, warehousing, etc.
The company large seamless steel pipe material are all made of TPCO tianjin continuous process, after years of the galactic mature production technology, all steel pipe wall thickness, inner hole smooth level off, without bad spot and internal screw and height difference.
High-precision cold-drawn steel pipe is a new kind of high-tech energy-saving product. Its application can save steel, improve processing efficiency and save energy. The so-called high-precision cold-drawing tube is the inner and outer diameter of the precision (tolerance range), the inner and outer surface of the surface finish, the roundness, the straightness good, the wall thickness uniformity and other advantages. Internal diameter tolerance: H8, H9, straight line 0.3mm/ 1000mm, 0.5mm/ 1000mm.
The company adopts the 250T hydraulic cold-drawing machine for cold drawing, the inner diameter of product specification: 40mm- 630mm, outer diameter 50mm- 820mm, wall thickness: 5cm-40cm, cold-drawn tube single branch length is less than 13.5 meters
Steel tube weight calculation formula:
[(outer diameter - wall thickness) * wall thickness] *0.02466= kg/meter (weight per meter)
