Overview

API tubing is an oil-country tubular goods product used in well completion and production strings. It should be ordered as tubing under API Specification 5CT, not as structural pipe, line pipe, or casing. The RFQ should identify the API 5CT edition, grade, outside diameter and nominal weight or wall, length range, end finish, upset type, and connection. API EUE and NUE are tubing connection references; proprietary connections require the connection owner's exact designation and acceptance criteria. Buyers should also state drift requirements, hydrostatic or non-destructive inspection scope, marking, thread protection, quantity, and destination. Grade, size, connection, and inspection availability remain subject to technical review against the complete order. Service conditions such as sour service require additional project specifications and material qualification.

FAQ

What is needed to quote API 5CT tubing?

State edition, exact grade, OD and nominal weight or wall, length range, upset type, end finish and connection. Add drift and inspection requirements, well service, quantities and destination. Confirm the offered combination against the complete purchase specification.

Can EUE and NUE tubing be interchanged?

EUE and NUE identify different tubing end and connection arrangements. Specify the connection required by the completion design. A matching nominal size does not approve substitution; changes require the buyer’s technical acceptance.

Does an API 5CT grade alone confirm sour-service suitability?

Provide the well service specification, operating environment and any additional material qualification or testing requirements. A grade name or reference to API 5CT alone does not establish suitability for a particular well.

Which inspection documents should the order specify?

Identify the required inspection certificate, material and heat identification, dimensional results and applicable thread inspection records. Add product-specific tests, acceptance criteria and witness points. Confirm the scope and document availability before placing the order.
