Liaocheng Shunxiang Building Materials Co., Ltd. (www.lcsxjc.com) located in Liaocheng City, Shandong Province Development Zone Industrial Park, Contact: Manager Ge Building Material Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling centrifugal ductile iron pipe pipe manufacturers, ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells and other premium quality of our products. Classification pipe joints flexible expansion joints with a single flange limited telescopic joint ductile iron pipe manufacturers, double flange limited telescopic joint, and other expansion joints. Pipe joints are flexible expansion joints of metal products, which have a higher tensile and compressive strength, excellent soft sealing performance, easy handling and other functions, is widely used in electric power, metallurgy, chemical industry, water supply and sewage treatment and other industries. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety GB milling cast iron pipe ductile iron pipe manufacturers, ductile iron pipe, cast iron pipe fittings of high quality flexible ductile iron pipe manufacturers ductile iron pipe, cast iron pit wells quality of our products. In the construction of the pipeline repair parts, due to the complexity and urgency of the situation, and 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.
