What Are API 5B Thread Gauges?

API 5B thread gauges are precision instruments designed to check and measure the threads of casing, tubing, and line pipes according to the specifications set out in API 5B.

The gauges ensure that the threads meet the dimensional requirements to provide a secure and leak-proof connection.

API 5B is a specification developed by the American Petroleum Institute (API) that covers threading, gauging, and inspection of casing, tubing, and line pipe threads used in the oil and gas industry.

The purpose of these gauges is to ensure the compatibility, interchangeability, and integrity of threaded connections in pipelines and drilling systems.
