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.

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.

Groups of Grade
Group 1: All casing and tubing in Grades with H, J, K, N and R
Group 2: All casing and tubing in Grades with C, L, M and T
Group 3: All casing and tubing in Grade P
Group 4: All casing in Grade Q

 

J55 and K55 are similar material in chemical composition and mechanical properties, especially J55 has lower minimum tensile requirement and lower elongation, others specifications are same like heat treatment methods, NDE test, Charpy Impact test, hydrostatic test.

J55/K55 minimum yield strength: 379-552 Mpa;
J55 minimum tensile strength: 517 Mpa, elongation ≥ 19%;
K55 minimum tensile strength: 655 Mpa, elongation ≥ 15%.
