While casing coupling is utilized for connecting two casings. Compared to integral connections, our API couplings are much simpler and cheaper to produce. Besides, coupling stock is with less risk of leakage due to less geometric errors in the connection parts. Classifications 1. According to its grade, it can be divided into J55, K55, N80-1, N80-Q, L80-1, C90, T95, P110, Q125 and other grade API couplings.

Mar 06, 2018 · A short length of pipe used to connect two joints of casing. A casing coupling has internal threads (female threadform) machined to match the external threads (male threadform) of the long joints of casing. The two joints of casing are threaded into opposite ends of the casing coupling. Standards and Technical Conditions for Supply:API Spec 5CT and 5B
How many types of threads for casing pipe do you know?Mar 13, 2018 · For casing pipe, the most popular threading type is LTC (Long thread coupling), STC (Short thread coupling) and BTC (Buttress thread coupling). For all casing sizes, the threads are not intended to be leak-resistant when made up.In the design of those threading types, you can find them in API 5CT or API 5B.
Types Of Threads For Casing Pipe (LTC,STC,BTC)Types Of Threads For Casing Pipe (LTC,STC,BTC) Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For casing pipe, most popular threading type is LTC (Long thread coupling), STC (Short thread coupling) and BTC (Buttress thread coupling).For all casing sizes, the threads are not intended to be leak resistant when made up.The design of those
Sound Transmission Class (STC ) is an integer rating of how well a building partition attenuates airborne sound.In the USA, it is widely used to rate interior partitions, ceilings and floors, doors, windows and exterior wall configurations (see ASTM International Classification E413 and E90).
What are differences between STC, LTC and BTC in OCTG Nov 30, 2020 · Common threads of OCTG casing pipe can be divided into three kinds:STC, LTC, and BTC. STC is short for short-round thread casing, LTC long-round thread casing, BTC buttress thread casing. There are three specified lengths of API LTC casing:R-1 is 4.88 ~ 7.62m, R-2 is 7.62 ~ 10.36m, and R-3 is 10.36m to longer.

What Are The Differences Between Casing and Tubing?ManufacturingSpecificationsQuality ControlWhat is casing pipe? Casing pipe, also called encasement pipe, is used in underground construction. Casing pipes safeguard many kinds of utilities, like water mains, electrical high-voltage lines, natural gas lines and fiber-optic communication lines from damage. These utilities need protection from human activity and natural elements. The construction of deep foundations also makes use of steel casing pipes. Casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into aAPI 5CT tubing Casing & Tubings A519 tubing OCTG API J55 Casing Pipe. J55.
