Product Description

High Quality 13 3/8 inch Api 5ct Grade K55 Steel Casing Pipe Buttress Thread Water Oil Well Casing Pipe



Casing and Tubing coupling

As we know, the coupling of steel pipes is a pipe or short pipe with threads on both ends and is used to connect pipes. The API coupling plays an important role in the connection of pipes and casings, since it requires more rigorous manufacturing processes than normal steel couplings. The recommended standard is API 5B.
