Success Stories

1. A producer in mid michigan had been recieving odor complaints from sour low producing wells. They had already serviced the hatches(springs, gaskets, cleaning, ect. ) The ownerselected to install liners on this set of tanks themselves(quick and easy)

Result: The next morning the operator/guager called the owners and said “What did you guys do? these tanks are all pressured up!

 Conclusion: By simply installing the liner the hatches sealed properly. Later it was determined that the flame arrestor was restricted.

The hatch liner repairs the sealing surface of a thief hatch base, giving the pressure gasket a smooth surface to seal to.

1. Clean

Clean base, all oil, particles, moisture, etc. must be removed from base surface.

2. Apply Adhesive

Apply adhesive to bottom groove of the hatch liner (We usually use Loctite 5900) and place it onto the base. Turn slightly and at the same time apply a little pressure.

3. Close & Lock

Close top and lock the hatch, this will help keep the hatch liner centered and have equal amount of pressure being pushed onto it.
