Precautions for Pressure Test of Ductile Iron Pipes

Ductile iron pipe pressure test is to ensure that after installation, to ensure the quality of its use, to prevent leakage of the state. At the same time doing pressure experiments, there are some areas need attention, once the bad deal will affect the suppression of the effect. The following ductile iron pipe manufacturers tell you what should be noted in the teeth of the process?




Ducting test


Attention 1: When the pressure experiment to clear division of labor, unified command, arrangements for the person responsible for checking the back, buttresses, interfaces, exhaust valves, etc., and clearly identified when the problem of contact signal.


Ductile pipe interface is completed, to do the back and gate, tee and other pipe reinforcement. From the low water, high exhaust, filled with water after soaking 24 hours after the test pressure 10min step-down is not greater than 0.05Mpa when qualified.


Note 3: water pressure test should be step-by-step, each step-up to 0.2Mpa is appropriate, after each step-up, the regulator checks no problem to continue to boost. Water pressure test, the back, support, pipe end and other nearby stations shall not be checked when the stop boost should be carried out.


Note: Four: cold weather in winter, it should take measures to prevent frost, the ductile pipe backfill appropriate increase, with multiple layers of grass curtain will be exposed to the interface package strict string of water and pressure test pipe wrapped wrapped insulation, Do not empty the water in time.


In summary, the suppression experiment is not very simple, you need to ask the professional staff to suppress the test to ensure that the results of the test, if the test time, in the event of a bad situation, so that we resolve in a timely manner. Ductile iron pipe manufacturers want to bring the information to help you!
