Similar to K55 except the minimum tensile strength is lower. API K55 is a general purpose pipe manufactured to API specification 5CT. Usually, this grade is most often used in casing applications. API N80 Type I is a lower cost alternative to standard Quench and Tempered API N80 (walls less than 0.500 inch).
K55 and J55 have no significant difference in the yield strength and chemical compositions. But the tensile strength of K55 is higher than the J55 casing steel. API 5CT K55 has better thermal fatigue resistance and crack resistance. In case of thermal production, the heavy wall of K55 casing is appropriate instead of J55 casing. In oil drilling, API K55 casing or tubing is relatively common type.
API grade K55 has the same yield as grade J55, but its minimum tensile strength is about 26% higher compared to J55. Yield strength: 379-552 MPa (55-80 ksi), Minimum tensile strength: 665 MPa (95 ksi) API color code: 2 bright green bands.
For thick wall pipes (D/t < 15), the tangential stress exceeds the yield strength of the material before a collapse instability failure occurs. k55 pipe yield strength..(2) Nominal dimensions are used in the collapse equations.

PSL1: J55 and K55 on the tube did not do destructive testing mandatory requirements; PSL2: J55 and K55 for all pipe shall be one or more of the criteria specified in 10.15.5 tested to find the inner surface of the outer surface of the pipe and can receive the level of L4 longitudinal imperfections. The main steel grade of API 5CT:
API 5CT K55 mainly offers to protect the wall surface of a well and also protect against the oil and also gas from leak. Layer on its surface area supplies extra security versus the deterioration. There is no distinction in the chemical structure and yield strength, however the tensile strength of K55 is higher than J55 steel.

Minimum Yield Strength: 30,000 psi: Maximum Yield Strength: None: Minimum Tensile Strength: 48,000 psi: Notes: This grade may be used for standard pipe, line pipe, or conduit pipeas specified in the various ASTM and API specifications.
API 5CT seamless steel tubing. Peotroleum and natureal gas industies - Steel pipes for use as casing or tubing for wells. API 5CT is a standard on the oil casing by American Petroleum Institute, mainly for the oil pipe, tubing and casing.
The API pipe body strength is the axial load required to yield the tube. This equation does not reduce the body strength of a tubular for tolerances on dimensions or for the API yield point anomaly. Py = pipe body yield strength ; lbs
K55: yield strength of 379MPa ~ 552MPa; tensile 655MPa; minimum elongation of K55 is 15%. 3. Impact test J55 and K55 impact test must be done, the minimum size of the sample lateral impact energy 20J, the smallest full-size sample longitudinal impact energy 27J. 4. Wall thickness detection
Due to their lower price compared to other steel grades, casing pipes of steel grades J55, K55, and N80 are a popular choice for wells without stringent anti-corrosion or strength requirements. M65, and R95 are newer grades, each with their own field of application.
API 5CT K55 and J55 oilfield petroleum casing pipe is quite similar to J55, there is no considerable distinction within the chemical composition and yield strength, howeverhigher than J55 steel pipe, K55 or J55 pipe are 654MPa and 519MPa correspondingly.
K55: API 5CT GENERAL SCOPE: API 5CT grades are commonly used in casing, production tubing, coupling stock, pup joints, and various down hole accessories. Energy Alloys stocks a variety of sizes in tubular form for this grade category.

API 5L X42 line pipe and API 5L X52 line pipe (Seamless and welded pipe) of all grades have PSL1 and PSL2 two product specifications, they are different on chemical composition, manufacturing processes, mechanical strength, heat treatment, test records, traceability etc. Actually, X42 and X52 etc. denote the minimum yield strength of the pipe k55 pipe yield strength
Comparing to other steel grades, casing pipes of grades J55, K55 are a popular choice for wells without stringent anti-corrosion or strength requirements. Here, we will introduce you the difference between K55 and J55.
Due to the difference in tensile strength, the required minimum elongation J55 is 19% and K55 is 15%. 5. Impact test Body pipe: PSL1: No difference between J55 and K55; PSL2: J55 and K55 require a horizontal minimum impact energy of 20 J for a full-size specimen and 27 J for a full-size specimen.
The most common materials for OCTG pipes are API H40, J55, K55, L80, N80, P110, and Q125 (casing and tubing pipes). These API grades feature increasing mechanical properties (tensile and yield strength). OCTG casing and tubing pipes are available in the following material grades:
Thus L-80 grade steel has a minimum yield strength of 80,000 psi. In other words, it can support a stress of 80,000 psi with an elongation of less than 0.5%. The letter in conjunction with the number designates parameters such as the maximum yield strength and the minimum ultimate strength which for L-80 pipe are 95,000 psi.
