|The principle is the same as that of the SOU250… the squeeze is carried out, the Top and Bottom beams are then mechanically locked together and then the hydraulic cylinders are ‘unclipped’ and used in conjunction with a second beam set.
Using this concept all four squeeze points are accomplished using just one pair of hydraulic cylinders.The Bottom Squeeze beam is fitted with ‘Pipe Stops’. These Pipe stops form a positive ‘stop’ between the Top and Bottom beams and hence optimise the squeeze gap in order to ensure the pipe is not over-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.
*Please note these sizes are for use with Mk1A Squeeze Off Units issued with Red Guide Tubes (as pictured). Please contact our technical department for further information.

Squeeze Off Stops are required in order to optimise the amount of compression (squeeze) of pipe wall. Squeeze off stops limit the amount of compression of the pipe wall to prevent damage to the pipe whilst ensuring that the optimum compression rate is achieved to limit the flow. Stops are available in sets of 8 (2 per Beam x 4 Beam Sets) in differing Diameter/SDR combinations. I.e. 315/11, 315/17.6, 400/17.6 and so on.
The Hy-Ram SOU400 Squeeze Off Unit complies with British Gas Engineering Standard PS/PL2: Part 7.
Final squeeze gap is not less than 90% of twice the minimum specified wall thickness.
