TMT Acid Plug

 

 

The Wellhead Acid Cap is designed for a H4 wellhead. The cap 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 hotstab in the top of the cap; this fills the cavity in between the two seals ensuring the wellhead internals will remain clean.

 

TMT can customise the tool to suit your requirements.
