Hammer union we manufactured is used to connect kinds of manifold and lines. It can be divided into three types: threaded connection hammer union, welded hammer union, anti-hydrogen sulfide hammer union. Sizes can be from 1 inch to 4 inch, cold working pressure from 7Mpa to 140Mpa(1000psi-20000psi).
Models of threaded connection hammer unions: fig 100, fig 200, fig 206, fig 400, fig 402, fig 602, fig1002, fig 1502.
Models of welded hammer union: fig 200, fig 602, fig 1002, fig 1502, fig2002.
Models of anti-sulfur welded hammer union: fig602, fig 1002, fig1502, fig2202.
Our hammer unions are exchangeable with FMC, WECO and Kemper hammer union.
