The thick wall tube is also called pipe material. The pipe material mainly used for petroleum geology drilling pipe, petrochemical used cracking pipe,But do you know what is thick wall tube?
With the definition of the thick wall tube,which tube’s the outside diameter and wall thickness ratio less than 20 is called thick wall tube.The mainly usege of the thick wall tube is used for petroleum geology drilling pipe, petrochemical used cracking pipe.
In the production process,pipe inside diameter is determined by the outside diameter sizing mill drill length. After sizing the pipe into the cooling tower through spray cooling pipe after cooling, it is necessary to be straightened. After straightening the steel conveyor belt to the metal detection machine (or pressure test) for internal testing. If the internal pipe cracks, bubbles and other issues, will be detected. After the selection of steel but also through strict quality control manual. After the steel quality, spray paint on number, size, batch number and so on. The production process of the thick wall tube is completed.
