How To Press The Ductile Iron Pipe?

Dec 06, 2018

In this article, the professional Ductile Iron Pipes Fittings Manufacturer will explain in detail the specific steps of the ductile iron pipe pressing.

When the Ductile Iron Pipe is installed, the water pressure test should be unified and commanded, and the division of labor should be clearly defined. The back, the pier, the interface, the exhaust valve, etc. should be designated to be inspected by special personnel, and the contact signal when the problem is found should be clearly specified.

After the Ductile Iron Pipe joint is completed, the ends of the ductile iron pipe test pipe section and the tee are closed with short pipe armor, short pipe B and blind plate. The test ductile iron pipe section is filled with soil to the top of the pipe 1250px and compacted. . Reinforce the back and gates, tees and other High Quality Ductile Iron Pipe Fittings. From low point into the water, high point exhaust, after immersing for 24 hours after filling with water, the ductile iron pipe is qualified when the pressure drop is not more than 0.05Mpa under the test pressure for 10min.

The water pressure test should be gradually boosted. It is better to use 0.2Mpa for each boost. After each boost, the boost will continue to increase if there is no problem.

Antifreeze measures should be taken when water pressure is applied in winter. The ductile iron pipe can be backfilled with ductile iron pipe soil and heightened. The exposed interface is tightly packed with multi-layer straw curtains; the stringed water and the pressure test temporary pipeline are wrapped and insulated, and emptied in time without water.

At last, Ductile Iron Pipes Wholesaler suggest during the water pressure test, the person behind the back, the support, the pipe end, etc. Check that the ductile iron pipe should be stopped when the pressure is stopped.
