oilfield TUBING pipe/j55 tubing/oil well CASING

High pressure oil pipe joints include a, d, c, b, f, g, h and k; Among them, various joints can be divided into direct, 90 degree bending and 120 degree bending. Type a is plane sealing type, and type d is spherical sealing type, which is generally used together with type c, and type c is 24.60 ° and 74 °; It is matched with 24 ° g type, type and 74 ° g type in turn; Type b is a ferrule type connector, matching with type c of 24 degrees; Type A is a disc type joint, which is fixed on a plane with two clips for sealing. Most of them are used in construction machinery; There are three types of g-type seals, 24, 60, and 74 degrees respectively, which are matched with c-type seals of the same degree. H-type seals with a seal groove machined on the conical surface of 24 degree g-type and 24 degree c-type seals; Type K is a quick change connector. It is not fastened with nuts. It uses a piston plus a Kashaw sealing method to facilitate replacement. It is commonly used in coal mines.

Casing 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
