HYD series Pipeline hydrostatic pressure testing machine is designed according to ISO 1167, ASTM D1598, ASTM D1599. It’s mainly used to test the plastic pipeline, compound pipeline, such as PP-R, PP-B, PP-A, PVC, PE, PE-X etc. Under a stipulated constant hydrostatic pressure force, keeping provision time; or inside the pipe, apply a constant and rapid hydraulic pressure to make the specimen broken in a short period time, check the max. pressure force, then calculate the ring stress. This tester is necessary equipment for plastic pipe manufacturer.
 

Feature of HYD-B series:
Computer controlled tester, and LCD meter control, pressure 10Mpa (100bar), 20Mpa (200bar), 16mm to 2000mm HDPE,PE,PVC, PPR etc., pipe and pipe fittings.

Principle:
Test pieces are subjected to a specified constant internal hydrostatic pressure for a specified period of time or until a test piece or pieces fail.
Throughout the test, the test pieces are kept in an environment at a specified constant temperature: this is commonly in water (“water-in-water” test).
The following test parameters shall be specified by the standard or specification making reference to this part of ISO 1167:
a) the type of end cap to be used (see 5.1 and ISO 1167-2:2006, 4.1);
b) the test temperature;
c) the number of test pieces;
d) the duration of the test under pressure and the criteria for a failure;
e) the test pressure, p, or the circumferential (hoop) stress, σ, to be induced by the test pressure.
