Cold-drawn precision welded pipe
Cold Drawn or Cold Rolled Precision Seamless Steel Pipe
Precision pipe is a kind of seamless steel pipe with high precision and brightness, which is produced by cold drawing or cold rolling process.Its inner and outer diameter size can be accurate to within 0.02 mm, precision steel tube inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks and ensure the bending and torsional resistance, relatively light weight, so widely used in the manufacture of precision machinery parts and engineering structures, pneumatic or hydraulic components of the product.
Precision steel tubes have seamless pipes and welded pipes.
In order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually in two roller mill, steel tube in variable cross section circular groove and immobility of the tapered plug is composed of an annular groove rolling. Cold drawing was usually in the 0.5 ~ 100T single chain or double chain drawbench.
Quality carbon structural steel cold dial seamless, with 10#、20#、35#、45#、20Cr、40Cr、15~42crmo﹑Q345、27simn、304﹑201、310s steel manufacturing, in addition to guarantee the chemical composition and mechanical properties to do pressure test, curling, expansion port, squash and other tests.
Precision tube feature
1.The outside diameter is smaller.
2. High precision can be used for small batch production.
3. Cold drawing products have high precision and good surface quality.
4. The transverse area of steel pipe is more complex.
5. Superior performance of steel pipe and dense metal.
Formula weight: cold drawn seamless steel tube (diameter - thickness) * wall thickness of *0.02466=kg/ meters (weight per meter)
