Product Description

 

Product Description

API 5CT oil casing can be divided into Seamless Steel Pipe and welded Steel Pipe.Welded steel pipe mainly refers to straight seam steel pipe.Large diameter oil casing is generally submerged arc welded straight seam steel pipe.The main application countries of this product are mainly distributed in the Middle East, Europe and America.The API5CT casing can be classified into R-1, R-2 and R-3 specifications according to its length. The main materials are H40,J55, K55, N80, L80, C90, T95, P110, Q125, V150and so on.Pipes made of oil casing have unique natural advantages in extreme high temperature and pressure environments. Under ISO9001, we own a set of complete and effective quality system in our factory. Furthermore, we has strict inspection and test system before shipping including dimensional inspection, strength test, tensile test, hardness test, hydrostatic test etc. Therefore, our API 5CT well casing has enough quality assurance to eliminate your worries.
Q125 is API 5CT standard oil pipe oil casing material, used for the manufacture of oil casing, oil well pipe, and petroleum machinery parts processing, strength of 125ksi/862Mpa above, is a kind of high strength oil pipe material.

Product Process

Steel ingot heating → hydraulic punching → reheating → extension → periodic rolling → reheating → sizing → cooling → straightening → pipe cutting → inspection

1. An annular heating furnace is required for ingot heating;
2. Punching and reheating with hydraulic press;
3. The oil casing plant uses a two-roller guide plate extension machine for extension;
4. Re-use a disc heating furnace for periodic rolling, and use a non-entry furnace for reheating, cooling, straightening, pipe cutting, and inspection.
