Figure 1502 | 10,000 PSI Sour Gas Hammer Union
C&C Industries
The C&C Figure 1502 Sour Gas Hammer Union is specifically designed for high-pressure applications involving corrosive and H₂S environments. Built to meet NACE requirements, it provides reliable sealing and material integrity in systems where standard carbon steel unions are susceptible to sulfide stress cracking and corrosion.
This version of the Figure 1502 is derated to 10,000 PSI for sour gas service, ensuring safe operation under conditions where material performance is critical. Utilizing the same turbulence-reducing design and lip-type sealing system, it delivers both pressure containment and protection of internal components.
Engineered for harsh environments, this union is essential for maintaining system integrity in sour gas and corrosive applications.
Typical Applications:
Sour gas systems, H₂S service, corrosive production environments, injection systems, high-pressure flowlines, and oil & gas processing

PERFORMANCE ADVANTAGES
Why the FIG 1502 Sour Gas Performs Where It Counts
PREVENTS SULFIDE STRESS CRACKING
IN H₂S ENVIRONMENTS
Standard carbon steel components can fail rapidly in sour gas service due to sulfide stress cracking. NACE-compliant materials are selected and controlled to prevent this type of failure, ensuring safe long-term operation.
MAINTAINS STRUCTURAL INTEGRITY UNDER
HIGH PRESSURE AND CORROSION
The combination of high-strength alloy construction and sour service material control allows the union to perform reliably under both pressure loading and corrosive attack.
PROTECTS SEALING SURFACES IN CORROSIVE
& HIGH-VELOCITY FLOW
The lip-type seal reduces direct exposure of metal seating surfaces to corrosive fluids and turbulent flow, extending sealing performance in aggressive environments.
REDUCES FAILURE RISK IN CRITICAL PRODUCTION SYSTEMS
In sour gas applications, failure is not just costly, it is a safety risk. This union reduces the likelihood of leakage or rupture, improving system safety and operational reliability.
