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.
J55/K55 identification API color code
J55 Tubing: One bright green band, coupling bright green and no
bands.
J55 Casing: One bright green band, coupling bright green and with
one white band.
K55 Casing and Tubing: two bright green, coupling bright green and
no bands.
