Product Description

API 5CT J55 casing and tubing are used in a variety of well applications for the petroleum industry. The J55 casing pipe is a relatively common one in oil and gas drilling. Its relatively affordable price point and its ability to protect the well make it a popular choice among well operators. The J55 tubing is similarly well suited for petroleum operations. Its steel makeup gives it greater strength and durability than some of the other options on the market, making it ideal for high-pressure applications. When used together, API 5CT J55 casing and tubing provide an economical and reliable solution for well operators.API 5CT J55 and K55 casing and tubing are relatively low grade material pipe among all API 5CT pipes, they have same chemical composition and same yield strength 379-552 Mpa but in different tensile, J55 tensile strength minimum 517 Mpa which K55 is 655 Mpa. J55/K55 are lower grade than N80, L80, P110 or T95, so they are a cheaper option material and widely used in non corrosive oil well installation without high strength requirement.
