  • SMI Hammer unions are manufactured by steel forgings using appropriate materials to specific pressure ratings.
  • SMI Hammer unions are available in a choice of end connections. API line pipe threads are standard.
  • Butt Weld End is available. Customer needs to specify schedule of pipe while ordering.
  • H2S service is available and all H2S service parts of SMI unions conform to the latest NACE specifications.
  • All SMI Hammer union components can be interchangeble with WECO on the same size and figure.
  • All SMI Hammer union nuts have three hammer lugs.
  • SMI Hammer unions for low-pressure services(Fig 100 - Fig 200) feature a primary metal-to-metal seal.
  • This metal-to-metal seal remains leak-proof even one surface is slightly pitted or misaligned.
  • SMI Hammer unions for Medium-pressure services(Fig 400 - Fig 600) is designed supplement the metal - to
    - metal seal with a resilient O-ring in the male sub. The replaceable O-ring extends useful life for unoin and
    protects the metal - to - metal seal against corrosion.
