What is the difference between precision seamless steel pipe andseamless steel pipe? Precision seamless steel pipe and seamless steelpipe is the difference between:
1, seamless steel pipe is the main feature of non welded joints, can withstand greater pressure. The product can be a very rough casting or cold drawing.
2, precision steel pipe is the product that appeared in recent years, mainly in the inner hole, outer wall dimensions have strict tolerances and roughness. The characteristics of cold drawn precision steel tube:
1 outside diameter smaller.
2 high precision to do small batch
3 finished drawing high precision, good surface quality.
4 the transverse area of the steel pipe is more complicated.
5 steel tube performance is superior, metal is more dense. The difference between hot rolled precision seamless steel tubes: hot rolled precision seamless steel tubes with continuous casting round billet slab or tube as raw material, after reheating furnace heating, high pressure water in addition to scale into the roughing mill, roughing feed of the cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, eventually after rolling through the laminar cooling and coiling machine coiling, become straight hair volume. Head and tail hair straightener roll often forms a tongue shape and the fishtail shape, thickness, width of poor accuracy, edge has wavy, hem, tower and other defects. Its weight is heavy, the diameter of the steel coil is 760mm. The straight after the cutting head, tail cutting, cutting edge and multi-step straightening straight and flat finishing line treatment, cut into boards or heavy volume, that is, to become: hot rolled steel plate, flat hot rolled steel coil, slitting with other products. Hot finishing rolling by pickling descaling and oil is made by pickling hot-rolled coils. Precision seamless pipe main varieties: DIN series high-precision precision bright precision seamless tube, hydraulic system dedicated precision seamless pipe, automotive manufacturing precision seamless pipe
