FIg1502 Weco Seal Rings
Functionality
The primary function of the seal in a hammer union is to prevent leaks and maintain pressure within the piping system. It ensures a secure connection between different sections of pipes or hoses, even under extreme conditions.
Materials
Seals used in hammer unions are typically made from robust elastomeric materials, such as:
Nitrile Rubber (NBR): Known for its oil resistance, NBR is commonly used in moderate temperature and pressure situations.
FKM: A fluoroelastomer that offers excellent chemical and heat resistance, suitable for harsher environments.
HNBR (Hydrogenated Nitrile): Provides improved temperature and ozone resistance compared to standard NBR.
Design Features
Steel-Backed Rings: Many hammer union seals are designed with a steel backing, providing added strength and ensuring consistent pressure application across the sealing surface.
Profiled Sealing Surface: The design of the seal often includes a profiled surface to enhance sealing ability and accommodate slight irregularities in the mating surfaces.
Applications
Hammer union seals are used in various applications, including:
Drill stem testing and blowout preventers in drilling operations.
High-pressure mud and cement lines.
Manifold systems and pipelines that require quick, secure connections.
Performance Considerations
The effectiveness of a hammer union seal is determined by its ability to maintain integrity under pressure, exposure to different temperatures, and resistance to chemicals present in transported fluids.
Regular inspection and replacement are crucial, especially in high-wear environments, to avoid potential failures.
