/03/15· Each pipe sample used for the squeeze-off test has length of at least five times of its diameter, following the recommendation given in ASTM F1041. As shown in Fig. 1(a) and (b), the squeeze-off tool consists of two round bars of 19 mm in radius, as suggested in ASTM F1563. Puhui Pipe manufacturer in China
This paper is about the squeeze-off tests on pipes made of PE 80, PE 100 and PE-Xa of different dimensions. After having squeezed off the pipes to a rate of 0.8 the air and water impermeability of the squeezed point is examined at
that the long term durability of PE pressure pipe is dependent upon its resistance to inhibit the initiation and slow growth of cracks. This failure mechanism can also occur in all types of fusion joints. Early research of HDPE pipes4.
SQUEEZE-OFF AND REROUNDING OF PLASTIC PRESSURE PIPES We elucidated the creep failure behavior of polyamide pipes. We conducted the hydrostatic test and Notched Pipe Test (NPT) at 80 and 90 °C for up to 10000 h for PA pipes whose creep failure behavior has not been fully elucidated yet.

Regent Squeeze Tools Regent HDPE Squeeze tools, from 1/2” to our largest at 24,” squeeze off HDPE pipe. Originally developed in the 1950s for use on HDPE service and main gas systems, these rugged tools provide unsurpassed reliability for control in an emergency in the flow of gas, crude, water or industrial products.
Squeeze-off is used in routine and emergency situations, to stop or nearly stop flow in polyethylene pipe by flattening the pipe between parallel bars. Gas and water industry utilizing polyethylene pipe in their systems have designed
FooPE100 ISO9001e Tools Squeeze off tools are designed to squeeze MDPE and HDPE pipe from ½” to 12” and HDPE pipe from ¾” to 2” safely and effectively. The smaller squeeze off tools are operated Manually with the larger models operated hydraulically through a single sPE100 ISO9001e hydraulic hand pump,
