FMC WECO STYLE HAMMER UNIONS
Hammer
unions, also called wing unions, are one of the most common connection types in
oil and gas industry as its reliable, heavy-duty, high-pressure for flow lines
at drilling sites. They are recommended to be used for manifold line
connections, pump suction & mud services, well test piping lines up to 2000psi
to run water, oil or mud. Subs and nuts of Fig.206 are interchangeable with
Fig.200. Fig.206 hammer unions have an additional O ring on the spherical
surface of the male sub to provide a leak proof seal. All dimensions of Fig.200
and Fig.206 are identical.Fig.211 is suitable for 2000 psi, but it has no metal
to metal contacts between subs, a resilient seal ring in the female sub provide
additional sealing to protection from corrosion.

WECO Hammer Union Seals
Lip type seal ring is an elastomer component, as a secondary seal to protect metal-to-metal against corrosion, which minimizes fluid flow turbulence while creating a pressure seal. Depending on the union figure it can be a lip type “seal ring” or an “O-ring”. Different material s are available to suit for different fluid service. Buna-N (NBR) is common for standard service, Viton (FKM) for H2S service.
When you want to buy the replacement hammer unions, please remember BETTER, BETTER is a one supplier focusing on the quality, all our hammer unions are API 6A approved, to deliver those high quality parts with a surprisingly low price is our advantage.Call to speak with one of our experienced sales to tell your request!
