    It is well known that 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.
