Instruction:
casing pipe coupling is a large diameter pipe that serves as the structural retainer for the walls of oil and gas wells,
or wellbore.It is inserted into a well bore and cemented in place to protect both subsurface formations
and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Surface casing
-Protects the well from contamination in shallow water and gas layers.
-Supports the wellhead equipment and sustains the weight of the other layers of casing.
Intermediate casing
-Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.
-Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.
Production casing (oil string)
-It is the conduit through which oil and gas pass from a below surface reservoir.
-It protects the well and separates fluids into various layers.
First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to
ensure that the thread accurately connects to the coupling. The threading type includes STC/BTC/LTC.
The casing pipes are strengthened by surface treatment and are subject to various inspections, including
drifting and hydrostatic tests before they are coated and packaged into casing pipe coupling
Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm.
