We provide comprehensive hammer union solutions based on SPM technologies, available in thread connection, welding type, and H2S service configurations. Our unions cover sizes from 1" to 4" with working pressures ranging from 1,000 PSI to 20,000 PSI (7 MPa to 140 MPa).

• Conventional Thread Unions: FIG100, FIG200, FIG206, FIG400, FIG402, FIG602, FIG1002, FIG1502 (1,000-15,000 PSI / 7-105 MPa)
• Welding Unions: FIG20, FIG60, FIG1002, FIG1502, FIG2002 (2,000-20,000 PSI / 14-140 MPa)
• H2S Welding Unions: FIG602, FIG1002, FIG1502, FIG2202, Tr120×6, Tr150×6, Tr180×8 (5,000-15,000 PSI / 35-105 MPa)

• Reliable Sealing: Quality rubber compound seal rings enhance load-bearing capacity and protect against erosion
• Fast Installation: Wing nuts and rigid ACME threads enable quick assembly without special tools
• Full Interchangeability: English system manufacturing ensures compatibility with international standards and SPM/FMC equivalents
• Color-Coded Identification: Different pressure ratings feature distinct colors for easy recognition

Our advanced manufacturing processes include precision NC machining for spherical adapters, specialized cutting tools for LP threads, and welding materials conforming to API 16C standards. H2S service unions are manufactured to strict NACE-MR0175 and API RP-14E requirements.

All hammer unions are securely packaged in export-grade wooden cases or pallets to ensure safe transportation worldwide.
