API Specification 5CT, 10th Edition. We are pleased to announce the publications of the 10 th edition of Specification 5CT, Casing and Tubing, and the 7 th edition of Technical Report 5C3, Calculating Performance Properties of Pipe Used as Casing or Tubing. These new editions provide technical updates that have reached consensus within API’s Subcommittee on Tubular Goods and will now give. API MPMS 11.1 V2 Manual of Petroleum Measurement Standards Chapter 11.1 - Volume Correction Factors Volume II Table 5B - Generalized Products Correction of Observed API Gravity to API Gravity at 60 Degrees F Table 6B - Generalized Products Correction of Volume to 60 Degrees F Against API Gravity at 60 Degrees F.

API SPECIFICATION 5L FORTY-THIRD EDITION, MARCH 2004 EFFECTIVE DATE: OCTOBER 2004 ERRATA DECEMBER 2004 American Petroleum Institute Helping You Get The Job Done RightM. SPECIAL NOTES API publications necessarily address problems of a general nature. With respect to partic­. API tubing, casing, and line pipe threads are governed by the Specification 5B. The Sixteenth Edition has made some major changes, including mandating the inspection of thread addendum. 5B 1.2 lists out the new inspection requirements including addendum. 5B 4.8 states that all threads shall be controlled in accordance with gauging practice.

API Spec 5CT – Specification 5CT/ISO 11960, Specification for Casing and Tubing, Eighth Edition, Petroleum and natural gas industries-Steel pipes for use as casing or tubing for wells.

Scope:

This 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 (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 contained in Annex H.
Peotroleum and natureal gas industies – Steel pipes for use as casing or tubing for wells.

The main steel grade of API 5CT:

· API 5CT J55, API 5CT K55, API 5CT N80, API 5CT L80, API 5CT P110.

Packing: Bare/bundles/crates/crate protection at the both sides of tubes or as per customers’ requirements .

This International Standard is applicable to the following connections in accordance with ISO 10422 or API Spec 5B:

· short round thread casing (STC);
· long round thread casing (LC);
· buttress thread casing (BC);
· extreme-line casing (XC);
· non-upset tubing (NU);
· external upset tubing (EU);
· integral joint tubing (IJ).

For such connections, this International Standard specifies the technical delivery conditions for couplings and thread protection.

For pipes covered by this International Standard, the sizes, masses, wall thicknesses, grades and applicable end finishes are defined.

This International Standard may also be applied to tubulars with connections not covered by ISO/API standards.
