Borehole sealing sleeve for Universal Hawlinger

Borehole sealing sleeves for Universal Hawlingers are used for drilling of cement-coated pipes. The time-consuming removal of the cement coating in the area of drilling as well as re-insulating is no longer necessary.

The borehole sealing sleeve is designed in two parts, with the inner sleeve with the sealing element in the borehole sealing the hole against the DCI pipe wall, and the outer sleeve with the O-ring sealing against the valve. On screwing the inner sleeve with the outer sleeve the sealing element is crimped and radially expanded in the bore.

After insertion of the sleeve, the pigging of the main line is possible only to a limited extent (slight internal projection).

Instructions for drilling and fixing the sleeve see operation manual.

Borehole sealing sleeves can be used only with Universal Hawlingers with FTHR 1 1/2" or ZAK 46.
