Heat Shrink Pre-Insulated Pipe Sealing Cap - Single and Double Outlet (GPPC)

About Heat Shrink Pre-Insulated Pipe Sealing Cap - Single and Double Outlet (GPPC)

Where a pre-insulated pipe ends, the foam insulation between the outer casing and the carrier pipe is exposed. If water gets in, the insulation loses its value and the steel underneath starts to corrode. Gala's pre-insulated pipe sealing cap closes that end.

The cap is moulded from cross-linked polyolefin and lined with hot-melt adhesive (mastic). Its large body shrinks onto the outer casing, and its outlet shrinks onto the carrier pipe where it leaves the insulation. GPPC1 caps have one outlet for single-pipe systems; GPPC2 caps have two outlets for twin-pipe systems.

Installation is done with a propane torch. Clean and abrade the casing and the carrier pipe, pre-heat both to at least 60 deg C (checked with a temperature-indicating stick), remove the release paper, push the cap into place and shrink it: casing first, then the step and the outlet, until the cap is smooth with no air pockets or lifted edges. The caps can be fitted in the factory, so the pipe end is already protected while pipes are transported and stored on site.

Typical users are manufacturers and installers of pre-insulated pipe for district heating and cooling, water pipelines and oil and gas lines. The range runs from small single-outlet caps to a cap with a 570 mm supplied bore, and every size is listed with its supplied and recovered diameters so the right cap can be chosen from the casing and carrier pipe diameters. Gala is an ISO 9001, ISO 14001 and ISO 45001 certified manufacturer.
