MJ Forgings is a trusted name among hammer union manufacturers in India, supplying high-performance hammer unions designed for demanding oilfield, drilling, production, and pipeline applications. A hammer union is a critical connection component used to join manifold systems and flow lines where frequent make-up and break-out is required. Known for strength, reliability, and pressure integrity, hammer unions play a vital role in maintaining safe and leak-free operations.
Hammer unions are commonly used to connect various types of manifolds and flow lines. Based on application and service conditions, they are broadly classified into threaded connection hammer unions, welded hammer unions, and anti-hydrogen sulfide hammer unions. As an essential category of oilfield drilling equipment, hammer unions are available in sizes ranging from 1 inch to 4 inches, with cold working pressure ratings starting from 7 MPa up to 140 MPa (1,000 psi to 20,000 psi).
As one of the reliable hammer union manufacturers in India, MJ Forgings offers a comprehensive range of threaded connection hammer unions including Fig 100, Fig 200, Fig 206, Fig 207, Fig 211, Fig 400, Fig 600, Fig 602, Fig 1002, Fig 1003, Fig 1502, Fig 2002, and Fig 2202. These models are engineered to meet diverse pressure, temperature, and service requirements across oil & gas operations.
The Fig 100 hammer union is an economical, low-pressure solution rated at 1,000 psi, widely used for basic manifold and line connections. Fig 200 and Fig 206 hammer unions are rated at 2,000 psi and are suitable for general-purpose manifolds, suction service, and corrosion-prone environments, with O-ring designs that enhance sealing performance. Fig 207 and Fig 211 models offer improved sealing, insulation, and protection against electrolytic corrosion, making them suitable for production systems and critical connections.
For medium-pressure requirements, Fig 400 hammer unions are widely used in mud service, pump suction, and line connections, offering pressure ratings up to 4,000 psi. Fig 600 and Fig 602 hammer unions are designed for 6,000 psi applications, including steam service, boiler connections, and high-flow mud systems, with replaceable seals and compact designs.
High-pressure operations such as cementing, fracturing, acidizing, testing, and choke-and-kill lines rely on Fig 1002, Fig 1003, Fig 1502, and Fig 2002 hammer unions. These models handle pressures from 7,500 psi up to 20,000 psi and feature advanced lip-type or ball-seat sealing mechanisms to minimize turbulence and protect metal-to-metal seals. Fig 1003 misaligning hammer unions are specifically designed to accommodate pipeline misalignment without compromising sealing integrity.
For sour gas and corrosive environments, Fig 2202 hammer unions meet NACE MR-01-75 and API RP-14E standards. These hammer unions feature heat-treated components, fluor elastomer seals, and are clearly marked for sour gas service identification.
MJ Forgings supplies hammer unions that are fully interchangeable with FMC, WECO, and Kemper hammer unions, ensuring compatibility and ease of replacement. With strict quality control, precision forging, and adherence to international standards, MJ Forgings continues to support the oil and gas sector as one of the dependable hammer union manufacturers in India.
