API 5CT is a pipe specification for casing or tubing in industrial gas pipelines and tube wells. There are different levels of specifications such as PSL1, 2, and 3.
API 5CT tubing varies in diameter, wall thickness, and length. The outer diameter ranges from 6mm to 219mm, the wall thickness ranges from 1mm to 30mm, and the length ranges up to 12000mm.
API 5CT casing has different steel grades, including J55, K55, N80, L80, and P110, etc.
API 5CT pipe specifications include short round threads, non-upset tubing, integral joint tubing, externally upset tubing, extreme pipe casing, etc.
