MH™ Plug Assemblies

View PDF version

for High Pressure Access Systems

The MH plug assemblies incorporate the following innovative design features which distinguish them from the HP plug assemblies and plug assemblies available from other major manufacturers.

  • A quick stab collet to facilitate easy attachment to the retrieval tool during removal and installation of the plug.
  • A coarse ACME plug thread to minimize the risk of galling or plug fouling.
  • A keyway feature to permit reproducible accurate orientation of installed hardware, coupon equipment, and injection nozzles.
  • A metal-to-metal back-up seal to minimize leakage, even if the access fitting assembly is subjected to high temperatures.
