API 5CT standard specifies the technical delivery conditions for steel pipes casing, tubing, and pup joints, coupling stock, coupling material, and accessory material, and establishes requirements for three product specification levels i.e. PSL-1, PSL-2 & PSL-3. The requirements for PSL-1 are the basis of this standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3, for all grades except H-40, L-80 9Cr, and C110, are provided.
For API 5CT GRADE L80 Carbon Steel Pipes covered by this standard, the sizes, masses, and wall thicknesses, as well as grades and applicable end-finishes, are provided. API 5CT Grade L80 Line Tubing may be ordered as casing in accordance with API 5C6.
By agreement between the purchaser and manufacturer, Cold Rolled Carbon Steel API 5CT Pipe standard can also be applied to other plain-end pipe sizes and wall thicknesses. This standard is applicable to products including these grades: H40, J55, K55, N80 all types, L80 all types, C90, R95, T95, P110, C110, and Q125.
API L80 Seamless Line Pipes standard is applicable to many connections in accordance with API Spec 5B short round thread casing (STC), integral joint tubing (IJ), buttress thread casing (BC), extreme-line casing (XC), non-upset tubing (NU), external upset tubing (EU) and long round thread casing (LC),
