Cold Drawn Technology of Spiral Steel Pipe
Spiral steel pipe cold drawn, hot rolled tube defects, such as cracks or spiral steel high-precision cold drawn pipe after the tank, in the course of the fracture, almost no plastic deformation occurs, it is brittle fracture. Brittle fracture is caused by a variety of reasons. Such as: the precip...Read more -
There are spiral steel annealing process in use, mainly in the following three ways
1, To stress annealing Stress relief annealing, also known as low-temperature annealing (or tempering), which is mainly used to eliminate annealing casting, forging, welding, hot-rolled, cold-drawn pieces residual stress and the like. If not eliminate these stresses will cause the steel after a c...Read more -
Surface Treatment of Precision Steel Pipe
Surface treatment of precision steel pipe is by changing the precision steel surface tissue heat treatment to alter one surface properties.
