Casing Pipe:
Petroleum casing pipes are steel pipes used to support the walls of oil and gas wells to ensure the normal operationPetroleum casing pipes can be divided into different steel grades according to the strength of the steel itself, namely
J55, K55, N80,L80, C90, T95, P110, Q125, V150, etc. Processing form of casing end: short round thread, long round thread,
partial trapezoidal thread,special buckle type, etc. Different well conditions and depths have different steel grades. In a
corrosive environment, the casing itself is also required to have corrosion resistance. In places with complex geological conditions,
the casing is also required to have anti-collapseperformance. It is mainly used to support the well wall during drilling and after
completion to ensure the progress of the drilling processand the normal operation of the entire well after completion.
The API casing is generally used for the borehole wall support in the drilling as well as after the completion of a well, so as to
make sure the smooth running of the drilling process and also the normal procedure of the whole oil well after well completion.
As a result of the advancement in recent years, making use of the product is much more substantial. It is generally utilized in oil,
gas, coal bed methane, water system, thermal electrical power generation, hydropower penstock, thermal electrical power generation,
dredging design, as well as other sectors.
This product generally makes use of smooth steel pipeline as the raw product. Some large diameter and special wall thickness items
make use of straight seam pipeline as the pipeline body. The body should be processed with screw strings at both ends. One end is
linked to the combining, while the other end is equipped with the string protector. Thread as well as coupling link are used between
the casings. In addition, the pipe body of various steel qualities ought to correspond to different couplings.
