Oil casing pipes are the lifeline which keep oil wells running. API 5CT Casing is a large-diameter pipe ,it serves as the structural retainer for the walls of oil and gas wells, or well bore. It has widely use in the oil industry.It is inserted into a well bore and cemented in place to protect both subsurface formations and the well bore from collapsing and to allow drilling fluid to circulate and extraction to take place. Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.
The API 5CT casing pipe‘s out diameter’s range is 4 1/2″- 20″ (114.3mm-508mm).And the types of the thread include LTC (Long Round Thread), STC (Short Round Thread), BTC (Buttress Thread) and other premium connections which can be made as per the given drawings.The casing pipe also has different length ranges.The length can be classfied into three kinds,they are R1,R2,R3 respectively.The length of R1 is from 4.88 to 7.62mm.The length of R2 is from 7.62 to 10.36mm.The length of R3 is from10.36 to 14.63mm. What’s more the API 5CT casing pipe also has different grades,such as H-40, J55, K-55, N-80, L-80, P110, Q-125.And the surface of casing pipe is Corrosion proofing water based paint.The Heat treatment of casing pipe include Normalized, Quencher, Temper.
