Tubing and Casing Thread Helium Seal Test Bench

Description

1. Application Scope

Bonor helium seal test bench is designed for high-pressure helium tightness test on tubing and casing thread connections. The maximum test pressure reaches 140 MPa in accordance with standard SY/T 6872-2012. Test data can be collected and printed by computer automatically. The system is equipped with automatic pressure compensation function and optional monitoring cameras to realize unattended pressure test. Widely adopted in petroleum, chemical and natural gas industries, it verifies the sealing performance of pipe threads to guarantee safe and stable operation under high-pressure, high-temperature and harsh downhole working conditions.
