Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of new ductile iron pipe Ductile iron pipe manufacturer specifications, ductile iron pipe, flexible cast iron pipe fittings, cast iron pit wells quality of our products quality. Major role in the expansion joint between the pump valve and pipe connections. Expansion joints have a certain role in the multi-displacement pipeline operation, the pipeline in operation due to the heating or cooling, and crustal subsidence forces have an important role in the expansion and contraction of compensation, so expansion joints can ease the pipeline running blind thrust, the pipeline play a protective, especially for the installation and maintenance of the pipeline provides a great convenience. Building Materials Co., Ltd. mainly produces Liaocheng Shunxiang variety of milling of cast iron pipe ductile iron pipe factory price Jigang, ductile iron pipe, cast iron pipe fittings flexible flexible ductile iron pipe factory standard, high-quality cast iron pit wells quality of our products. Pipe expansion joints material, size, type, quality should comply with the design documents, and current national standards should be visually inspected, failure shall not be used. When properly applied thermal expansion joints between two expansion joints (usually 20 ~ 40m), and each expansion joints on both sides (refer to the far side) should be set to a fixed bracket. Should be attached to each batch of ductile iron pipe fittings factory quality certificate on which specify: the supplier (manufacturer) name; product names and specifications; trial to test the water pressure or air pressure; the standard number; should prevent break something. Warehouse space to store the tube should be flat, neatly. In the wave of market economy, companies rely on talent, technology and scientific management, continuing to explore the adjustment of development strategy, serious and realistic, solidarity, strong technical force, excellent equipment, perfect quality inspection system, to provide users with reliable products quality and satisfactory service to establish and develop long-term stability of the economic and technical cooperation.
