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. In the construction of the pipeline repair parts, due to the complexity of the situation and the urgency of the national standard ductile iron pipe manufacturers, sometimes need to take a flexible approach, but not necessarily stick to the normal maintenance procedures. For example according to the provisions generally are not allowed to use wedge plugging, but in case of emergency first with a wedge driven into the sealing leaks, loss of control of further expansion, then shut the door in the gate and then pull out the wedge, the use of welding repair. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipes, ductile iron pipes, ductile iron pipe manufacturers, high-quality flexible cast iron pipe fittings ductile iron pipe manufacturers, cast iron pit wells quality of our products. There are two ends of the flange and the Order of the disc-type expansion joints expansion joints, expansion joints casing retainer for town water towers, pumping stations, water meters and valves installed removable offer great convenience, as well as a result of long-distance pipelines Telescopic problems caused by temperature difference, played a good role to fill, replacing the U-tube. Casing bearing plate expansion joints can be used for water supply and drainage engineering, thermal engineering for the general temperature by 250 ℃, 1.6MPa pressure by the factory.
