We can provide various hammer unions based on the introduced technologies from SPM, including thread connection type, welding type and H2S service unions. 1"~4" and CWP of 1000Psi~20000Psi(7MPa~140MPa) unions are available. For easy identification, unions with different pressure ratings will be painted in different colours, and there are evident marks indicating size, connecting mode and pressure ratings.
The model of conventional union (thread connection): FIG100、FIG200、FIG206、FIG400、FIG402、FIG602、FIG1002、FIG1502;rated: 1000psi(7MPa)～15000psi(105MPa).
The model of Welding Union: FIG20、FIG60、 FIG1002、FIG1502、FIG2002;rated: 2000psi(14MPa)～20000psi(140MPa).
The model of H2S welding union: FIG602、FIG1002、FIG1502、FIG2202、Tr120×6、Tr150×6、Tr180×8;rated: 5000psi(35MPa)～15000psi(105MPa).
Reliable Sealing performance
Seal rings are made of quality rubber compound which greatly enhance load-bearing capacity and sealing performance and protect connectors from erosion. Different pressures and applications have different sealing method.
Wherever they are, wing nuts and rigid ACME will ensure quick installation or dismantling without special tools.
All unions are made in English system, and can be interchanged with products in international market. Seal rings are fully interchangeable with SPM or FMC equivalent products; Marks of size and pressure in wing nuts are formed in die-forging model, same as international products.
Advanced Machining and Inspection Method
Spherical adapters machined by precision NC machine tools and LP thread machined by special cutting tools can ensure high sealing performance; Wing nuts machined by NC machines have high strength and load-bearing capacity; Welding materials and welding grooves conform to API 16C; Unions for sour gas environment are strictly manufactured to NACE-MR0175 and API RP-14E.
