With the highest yield strengths among all API 5CT casing grades, P110 and Q125 are ideally suited for high pressure formations in deep wells. However, as steel becomes more susceptible to sulfide stress cracking the higher the yield strength, both grades should not be used in H2S environments.
Yield strength collapse. Yield strength collapse is based on yield at the inner wall using the Lam thick wall elastic solution. This criterion does not represent a "collapse" pressure at all. For thick wall pipes (D/t < 15), the tangential stress exceeds the yield strength of the material before a collapse instability failure occurs yield strength of k55

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.
API 5CT K55 oil casing pipe contains the sulfur and phosphorus contents of respectively less than 0.030%. Its chemical and physical properties are basically similar to J55. However, our product claims higher tensile strength than the J55 type. The minimum value is 95ksi.
This grade J55 oilfield steel casing pipe serves to protect the oil pipe. The national standard steel grade of J55 oilfield steel casing pipe is 37Mn5. Moreover, this type product can provide the elongation rate of 0.5%, the yield strength range from 55 to 80ksi, and the minimum tensile strength of 75ksi.
API K55 Minimum Yield Strength: 55,000 psi Maximum Yield Strength: 80,000 psi Minimum Tensile Strength: 95,000 psi Hardness Requirement: None Notes: General purpose pipe manufactured to API specification 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.
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.

Application Fileds of API 5CT Pipe Grades. K55: API grade K55 has the same yield as grade J55, but its minimum tensile strength is about 26% higher compared to J55. M65: Not used that often, M65 is the only steel grade among the general purpose casing grades with the requirement of a restricted maximum hardness.
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.
Fatigue Strength The fatigue strength is defined as the maximum bending stress amplitude which a material withstands for 107 load cycles under symmetrical alternate load without breaking. It is dependent on the temper tested and is about 1/ 3 of the tensile strength R m. K55 130 140 150 160 170 180 190 200 210 220 0 5 10 15 20 25 30 500 C 450 yield strength of k55
