NEEDLE VALVES - Butt Weld type
  • Welding always Preferable to the piping systems to join tubes with valves where the end user has to avoid any leakage problem of fluids or gases at High Pressure.
  • Needle valves with Butt weld type connection are used for welding to tube end with valves in the Oil & gas industry to lower the risk of leakage of fluid at High pressure & lower rsk of leakage of viscous gases from the connections.
  • Needle valves with Butt weld type having Sqaure body Shape & socket hex adaptors screwed on both side of Body.

  • Seamless Tubes of the same Size of Socket has to be weld at both end of the Needle valve Butt weld type:
