Factory supplied threaded socket stainless steel couplings
The CASING
is threaded to shorten the running time. The casing is a disposable material. Once
problems occur in use, it will cause great losses, so the quality requirements for
the casing are extremely strict.
The special products of casing include
special button type casing and casing with special materials and properties such as
sulfur resistance, corrosion resistance and collapse resistance. Special button
casing is mainly used for deep well cementing where the tensile strength of ordinary
casing does not meet the requirements, and generally only one section is used at the
wellhead; Sulfur resistant and corrosion-resistant casing is mainly used in deep and
ultra deep wells of sour oil fields; Destructive casing is mainly used in deep wells
and ultra deep wells in oil fields due to its high collapse pressure and good
mechanical and collapse properties.
Couplings are used to connect two joints of TUBING COUPLING or casing pipe together.
Couplings are short length of heavy wall pipe with the same threads on each end.
manufactures TUBING coupling and casing tubing coupling strictly comply with API 5CT latest standard.
