- Thread Gauging
Acme thread and line pipe threads are gauged by standard plug & ring gauges.
- Sealing Design
The conical and spherical surfaces of the female and male subs respectively form an effective metal-to-metal seal in case of low pressure services.
For medium pressure mostly an ‘O’ ring is provided in the male sub in addition to the metal to metal seal. For high pressure a Lip type seal ring is provided for primary seal in the female sub. The seal protects the secondary metal to metal seal from corrosion and limits fluid flow turbulence. For sour service applications Viton seals are provided.
