Outdoor water supply stainless steel pipe fittings, when the rain period construction should dig drainage groove, collecting well, ready to pump (submersible pump), pumping equipment such as rubber hose, so that the water pumping, should keep rain water bubble idler, avoid the accident of drift tube, after the completion of the construction should be timely backfill soil. Stainless steel pipe fittings
Winter construction, we should pay attention to:
(1) for asbestos cement interface, should use hot water mixing material, but not more than 500 c water temperature, such as expansive cement interface, the water temperature should not exceed 350 c;
(2) the temperature falls below – 50 c, unfavorable to the above two kinds of material interface,
(3) after the interface, can use brine mixing sticky mud off mouth maintenance, and cover a good grass curtain. Also can use warm (not frozen) landfill soil interface heat preservation;
(4) testing, the exposed tubes or interface should be cover tightly with careless, no outlet pipe shaft should be backfill, pressure test finished as soon as possible will put clean water, do the preparatory work before the pressure test and pressure testing of water, drainage, etc.
