In accordance with the cross-section and shape, spiral pipe is divided into the sub-shaped tubes and tube. Perimeter commensurate area of a circle is the largest, so you can transport more liquid. Therefore, the vast majority is circle tube, each spiral are tightly controlled after the hydrostatic t
The so-called seamless stainless steel pipe and carbon steel seamless pipe distinction, mainly refers to the difference in carbon steel and stainless steel design rules, which are a few differences are summarized as follows: First, the stainless steel produced during cold work hardening, for example
OCTG pipe are steel pipes used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after drilling and completion.
