The key of quality for pipe material should be thickness uniformity, pipe material’s wall thickness is not controlled directly affect the quality and usefulness of steel pipe, thick wall steel pipe, large diameter seamless steel pipe for general use in a variety of machining, thick wall parts processing, uniform wall thick-walled steel pipe will directly affect the quality of post-processed parts, pipe material wall is not controlled, the overall quality of steel is not strictly.
Pipe material are favored as oil tools material because they offer a combination of mechanical properties that are unique and not found among non-metals. Pipe Material are generally strong and many can be loaded or stressed to very high levels before breaking. One property of API pipe material of interest is their capacity to exhibit a high degree of elastic behavior in their early load-carrying capacity. This is a very important property for effective use of the pipe material as oil tools material.
This is the unique quality of pipe material ,its high quality is very popular in the oil industry.
