Well Testing Flowheads


WOM has over the years gained considerable knowledge and experience in the design and manufacture of Well Test Products. These products include Flowhead, Surface Safety Valves (SSV), Choke Manifolds.
WOM have large share in market for well testing equipment design and Manufacturing. WOM can design Flowhead & Surface Test Trees to the customer’s specific need including multiple configurations, incorporating Lower Master Valve (LMV) integral to flowhead block, LMV below Swivel to various industry-standard pressure and temperature ratings and service requirements.

Product Features/Benefits

  • WOM’s flowhead incorporate Magnum Gate Valves which have set the industry standard for reliability
  • Designed with ACME Threads to accommodate high tensile load capacity.
  • API-17G analyzed ACME thread connections.
  • API-17G Qualified swivel.
  • Top Handling Sub compatible to standard elevator sizes.
  • An oil or grease filled swivel assembly below the central body of the Surface Test Tree enables tubing to rotate freely, providing a means to manipulate the tool string while the test tree remains stationary.
