Quick Overview

General

requirements in sizes 1 to 12" with ratings up to 20,000 PSI cold working pressure. Unions for sour gas service are
manufactured in accordance with NACE MR-01-75 & API RP-14E.
Interchangeability
ACT's Hammer Unions are interchangeable with WECO or other manufacturers adhering to the industry standards.
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 '0' 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.

process is used to ensure better service and longer life in extreme conditions.
