To water polo refill tube 12 allow water seepage water pressure test? To water polo refill tube 12 allow water seepage water pressure test is 17. 60 m3 /( 24小时公里) 。 Indoor water supply pipeline hydraulic pressure test must meet the design requirements. When the design not specified, all kinds of test pressure of the water pipeline system are working pressure of 1. Five times, but shall not be less than zero. 6MPa。 Testing method: metal and pipe water supply piping system under the pressure test for 10 min, and pressure drop should not be greater than zero. 02 mpa, then checked to pressure of work, should not leak; Plastic pipe water supply system should be regulated under test pressure 1 h, pressure shall not exceed 0. 5 mpa, and then in the working pressure of 1. 15 times condition stabilized 2 h, pressure drop, shall not exceed 0. 03 mpa, at the same time check the joint leakage is not allowed. Ductile iron pipes to choose the main control parameters of the nominal diameter, working pressure, connection mode, etc. Mild, thin wall, high pressure, impact resistance, corrosion resistance, seismic resistance and other properties. Pipeline interface using the flexible interface, and there are certain elongation and the deflection Angle. He has the advantages of casting' target='_blank'>cast iron pipe and steel pipe materials, avoid the shortcoming of the iron and steel. ( The original from: http://www. xexfoundry。 com/)
