Yongzhou ductile iron pipe fittings _ Shunxiang ductile pipe _ ductile iron pipe fittings manufacturer provided by Shunxiang ductile pipe. Yongzhou ductile iron pipe fittings _ Shunxiang ductile pipe _ ductile iron pipe fittings manufacturer is Liaocheng Shunxiang Building Materials Co. (www.lcsxjc.com) 2014 been newly upgraded Building Materials Co. launched Liaocheng Shunxiang mainly produced all kinds of cast iron milling ductile iron pipe fittings prices, ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells and other premium quality of our products. Flexible expansion joints pipeline inspection standards before leaving the factory: 1, flexible pipe expansion joints to be done before leaving the factory hydrostatic test and inspection GB integrated flexible ductile iron pipe fittings, test pressure is 1.5 times the nominal pressure, pressure 20 minutes without leakage is qualified. 2, the flexible pipe expansion joints hydrostatic test shall notify the scene to witness the tender side of ductile iron pipe fittings manufacturer, after passing the factory. 3, the inner and outer walls of the pipe are flexible expansion joints should be corrosion paint brush in water quality to adapt to the requirements. 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. Ductile iron pipe fittings buried deep freeze should be based on the degree of ductile iron pipe every year there will be a new standard, a new standard developed countries also increased the demand for production processes, quality control, and use on the general view is technically a prance ductile iron pipe . The proposed new standard is also conducive to "energy saving" will help decrease cost of raw materials and engineering costs, conducive to the implementation and application of ductile iron pipe, which is the international cast pipe open trend.
