|Pipe range: 250-400mm Diameter, PE100, 7 Bar
At the request of Transco (British Gas), Hy-Ram has developed a ‘special’ Squeeze Off unit for use on PE100 / SDR11 pipe at pressures up to 7 bar.
Designed specifically for this application, the ‘controlled release’ technique showed benefits over conventional squeeze off in terms of reducing the risk of pipe damage, specifically crack propagation on release of squeeze.
Tests were carried out by Transco up to 315mm diameter, however the unit has been designed to enable 400mm pipe to be installed.
The Unit is supplied with an electrically driven Hydraulic Power Unit.
The unique design is similar in principle to the SOU400. The pair of hydraulic cylinders are detachable and can be used on each of the four Squeeze points.
The Bottom Squeeze beam is fitted with ‘Pipe Stops’ to suit the diameter and wall thickness (SDR) of the pipe to be squeezed.
|Pipe Stops – A set consists of 8 x Stops, each Stop is unique for a fixed Diameter / SDR combination. Stops can be custom made for any specified pipe. Codes as follows are for individual stops (other sizes available on request):
