Frequently Asked Questions - API 5CT Training

API Specification 5CT covers the manufacturing requirements for casing and tubing used in oil and gas well construction. It specifies material grades, chemical composition, mechanical properties, dimensional tolerances, heat treatment requirements, threading and coupling specifications, inspection methods, test requirements, and documentation and marking requirements. It applies to tubular goods that carry the API monogram and is widely referenced in oil and gas procurement, drilling engineering, and well completion specifications worldwide.

API 5CT training is valuable for quality engineers and inspectors at tubular goods manufacturers, procurement and supply chain teams who qualify and manage casing and tubing suppliers, drilling and completion engineers who specify API 5CT grades for well programmes, and third-party inspectors and auditors who witness testing or conduct mill audits. Anyone involved in the production, procurement, inspection, or compliance verification of API 5CT casing and tubing will benefit from this course.

API 5CT defines several casing and tubing grades, each with different mechanical properties, chemical composition requirements, and intended applications. Common grades include J55 and K55 (lower strength, general use), N80 (medium strength, two types: N80-1 and N80-Q), L80 (sour service - H₂S resistant), C90 and T95 (higher strength sour service grades), P110 (high strength, non-sour environments), and Q125 (highest strength grade). Grade selection depends on well depth, formation pressure, temperature, and H₂S content. This course covers the selection criteria, heat treatment requirements, and inspection differences between all major grades.
