introduction

API 5CT is a piping specification for casing or pipes in industrial natural gas pipelines and tube wells. It has different levels of specifications such as PSL1, 2 and 3. Api 5ct pipes have different carbon and chromium contents in different product specification levels, and Api 5ct pipe sizes vary in diameter, wall thickness and length. The outer diameter range is from 6mm to 219mm, the wall thickness range is from 1mm to 30mm, and the length range is up to 12000mm. Api 5ct casing is available in different steel grades, including J55, K55, N80, L80 and P110, etc. These are different mechanical performance oriented grades. Pipes also come in different connection types. Api-5ct pipe specifications include short round thread, non-thickened oil pipe, integral joint oil pipe, externally thickened oil pipe, extreme pipeline casing, etc. If it is a welded type, the weld should be heat treated to a minimum temperature of 540°C (1000°F), or a certain treatment method should be used to ensure that there is no untempered martensite structure in the weld.
