Oilfield Tubing Pipe

Tubing Pipe is a pipe or hollow cylinder for the conveyance of fluids (liquids or gases).

The terms ‘pipe’ and ‘tubing’ are almost interchangeable, although minor distinctions exist (generally, “tubing” implies tighter engineering requirements than “pipe”).

Cold-Drawn Cold-Rolled Seamless Steel Pipe

Seamless Cold-Drawn or Cold-Rolled Steel Tubes for Precision Applications High precision cold drawn seamless steel tube identifies the precision steel pipe with high dimension precision (inside diameter and outside diameter), good surface finish, excellent roundness and straightness, and uniform wall occurrence. It can be very popular in mechanical structure and hydraulic gym equipment. This cold […]

API Steel Grade Category and Color

API standardized several grades of steel that have different chemical content, manufacture processes, and heat treatments and, therefore, different mechanical properties. API organized these tubing grades into three groups. Group 1 is for all tubing in grades H40, J55, and N80. Group 2 is for restricted-yield tubing grades L80, C90, and T95. Group 3 is […]

Premium Connection

Special connections are used to achieve gas-tight sealing reliability and 100% connection efficiency (joint efficiency is defined as a ratio of joint tensile strength to pipe body tensile strength) under more severe well conditions. Severe conditions include: High pressure (typically > 5,000 psi) High temperature (typically > 250°F) A sour environment Gas production High-pressure gas […]
