Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipes, ductile iron pipes ductile iron water pipe elbows, flexible cast iron pipe fittings, cast iron pit wells quality of our products quality. Due to the different circumstances of each point in the vicinity of the heat pipe flexible expansion joints weld heat-affected zone can be divided into the fusion zone and overheated zone, normalizing area and part of phase transition zones. Flexible expansion joints of pipe weld fusion zone and base metals is handover transition zone between the solidus and liquidus temperatures in this area, as part of the welding process, the temperature of the base material to melt, it is also known as semi-melted zone . At this point, to melt the metal solidifies into tissue ductile cast iron pipe manufacturers offer water, heated to melt the metal temperature is too high because of the formation of coarse-grained overheating at low double-flange steel dowel joints welded pipe flexible telescopic Although small soldering area (0.1-1mm) but because of its strength and toughness are decreased, and connector end faces here changes can lead to water stress concentration ductile iron pipe prices, so the fusion zone of welded joints determines to a great extent on performance. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of ductile iron pipe milling of cast iron water pipes, high-quality ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products. The ductile metal conductor tube electrolytic corrosion resistance is usually buried in the ground can be measured current capacity must, by the appearance of corrosion of a metal body as a result of this current is called electrolytic corrosion. Ductile iron pipe because the resistance was largely used for municipal water supply, pipelines, water consumption, etc., to meet customer needs in various industries. Flying ductile iron pipe water supply water _ ductile iron pipe manufacturers offer _ Shunxiang ductile pipe provided by Shunxiang ductile pipe.
