9.Application:
Casing Pipe is widely used for fastening oil and gas well wall or borehold, with bigger diameter than tubing, including surface casings, technical casings and oil layer casings.

Technical parameters of casing pipe:
Pls see technical data page

T95 steel grade can be divided into T95-1 and T95-2.We have the ability to detect the whole process and fully guarantee the high quality of products.

 Oil casing is the important lifeline for maintaining oil wells’ operation. But geographical environment is totally different in different areas and the connection of underground force is very complex. A variety of forces acting on the pipeline together, for example: tension, pressure, bending and twisting stress, all of which require oil casing should reach a higher level of quality. Oil casing's damage for some reason will cause the oil wells'production decline; some time seriously it will make well abandonment. So our company produces C90 steel grade oil casing strictly according to the API 5 CT standards.
