TMT Wellhead Acid Plug

The TMT Wellhead Acid Plug is designed for an H4 wellhead.



Cost effective

Field proven

ROV operated

Low maintenance

The plug will seal around the top surface of the wellhead as well as seal the internal flowline. The internal seal depends on the length of the mandrel/stinger, at the base of the stinger there is a rubber flange.

A biological inhibitor (generally acid) is then injected through a hot stab in the top of the cap; this fills the cavity in between the two seals ensuring the wellhead internals will remain clean.
