A hammer union seal is a critical component used in the connection of pipes and equipment in the oil and gas industry, as well as other high-pressure applications. The primary function of the seal is to ensure a leak-proof joint between two sections of piping or between a pipe and a variety of equipment, such as valves, pumps, and manifolds.
Hammer unions are classified based on pressure ratings and intended applications (e.g., low-pressure, high-pressure, sour gas service).
Common types include FIG1502, FIG1002, and FIG602, which denote the pressure rating and design family.
Application:
1.Oil and Gas: Used extensively in drilling, fracturing, and production operations. They connect flow lines, choke and kill lines, and other high-pressure lines.
2.Industrial: Also found in industries where high-pressure fluid transfer is necessary, such as chemical plants and mining operations.
