Shijiazhuang ductile iron water pipe _ Shunxiang ductile pipe _ ductile iron water pipe specifications provided by Shunxiang ductile pipe. Hebei ductile iron water pipe _ Shunxiang ductile pipe _ ductile iron water pipe fittings manufacturer is Liaocheng Shunxiang Building Materials Co. (www.lcsxjc.com) 2014 launch of Liaocheng been newly upgraded Building Materials Co., Ltd. mainly produces Shunxiang variety Ductile iron pipe, ductile iron pipe, ductile cast iron pipe fittings flexible water supply cast iron pipe fittings, cast iron pit wells and other premium quality of our products. Flexible pipe expansion joints GB/T12465-2007 national standard is the latest standard pipeline equipment, using the latest standard products manufactured steel expansion joints and pipe connections can adapt to compensate for valves and piping, valves for easy disassembly. Pipeline expansion joints shall meet all kinds of pressure ductile iron pipe fittings water pricing system that may be encountered due to the rapid closure of the valve ductile iron water pipe specifications, the system may encounter positive and negative pressure, respectively: maximum positive: 1.0MPa. Maximum vacuum:-0.10MPa. Brushing requirements for the two end-face, dry film thickness of not less than 210. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipe, high quality ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products. Corrosion resistance of ductile iron pipe fittings for ductile iron pipe transporting water and gas pipes, buried in the soil, the first being a tremendous impact on the surrounding soil chemical and physical function, when the tubes are arranged in long-distance pipelines constitute When a successive energization entity, is a serious corrosion of the pipe element, in other words, according to the soil buried pipeline corrosion is not the same, do not show the same characteristics of the layout according to this difference, the difference constituting the oxygen concentration cell, concentrated Some of the time difference between the batteries and other batteries can of water is strong ductile iron pipe fittings wholesale, thus laying a powered through the soil in such entities, long-term currents occur, some of which will constitute the anode current is very severe corrosion.
