Water pressure test should meet the requirements

(1) The hydrostatic test shall be carried out after the system has been flushed. (2) water pressure test should be per component, the collector as a unit, by group or by loop. (3) water pressure test should be carried out twice, respectively, before the pouring of concrete before the reign of rough rougers and the filling layer after the expiration of the maintenance of the filling tube; the best heating pipe laying before doing a test. (4) the test pressure should be 1.5 times the working pressure, and should not be less than 0.6Mpa. (5) test method: the test pressure, the regulator 1h, observe the pressure drop, if the pressure drop is not greater than 0.05Mpa, that qualified. (6) water pressure test should be used to slow down the manual pump, boost the process to observe and check the presence or absence of leakage. (7) in the case of freezing may test pressure, the pressure test pressure should be completed after the tube of water to dry, but only the air pump is blowing is not clean, it is recommended to use warm cleaning special tools, Each road tube, for drainage, so that the real guarantee of each tube, there will be no drop of water to ensure that no pipe freezing, practice has proved that there are many use of air pressure test.

PE-RTII Oxygen-resistant heating tube custom specifications manufacturers where?

PERTII-type oxygen to warm the pipe has been popular in foreign countries, the domestic pe-rtII oxygen to warm the current tube is still the ranks of high-end heating pipe, slowly will be popular; pertII oxygen to a good solution to solve the problem of oxygen permeation To warm the system in the installation and use of metal components to meet, such as valves and other metal parts, the general pert to warm the plastic and other plastic bite the body of the abundance of the agent by the ax of the hot water circulation process metal parts can easily be corroded, This will be detrimental to pe-rt to the long-term use of the warm-pipe system, the new pertII oxygen to warm the tube to solve this problem, so that the heating system to greatly improve the life of the heating system to ensure that the pe-rtII to warm the system safe use 50 Years or more.
