How to distinguish the difference between precision pipe and seamless steel pipe

Precision steel pipe and seamless steel pipe are two common steel pipe products on the market, with some similarities, but there are also differences. 1, the main feature of seamless steel pipe is no welded joints, can withstand greater pressure. The product can be very rough cast or cold drawn parts. 2, precision steel pipe is a product that has appeared in recent years, mainly the inner hole and outer wall size have strict tolerances and roughness. What is precision steel pipe: Precision steel pipe is a kind of high-precision internal and external bright seamless steel pipe material after cold rolling treatment. Because the inner and outer walls of the precision steel pipe have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening without cracks, etc., it can be done, so it is mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless pipes.
