> Model no. 1411 The spiral pipe cutter is used for the preparation of samples to determine delamination between the various ma­te­rial layers of multilayered polyethylene pipes. The spiral pipe cutter enables carrying out both examinations to ASTM and DVGW stan­dards. According to ASTM, the angle of intersection must be 45°, while DVGW requires a section with a width of 5 – 10 mm. In both cases the straight length of the spiral must be at least 5 x the pipe diameter. To enable tests to be carried out in accordance with both stan­dards, the spiral pipe cutter offers an adjustable angle of intersection. The pipe can be cut both manually and with an electric drill.
