Ductile iron pipe and high resistance to internal pressure and corrosion resistant, full strength and toughness. High impact strength, mechanical joint flexibility and scalability to facilitate joint construction, for normal soil conditions. Do not need to make special sand tube group. and may use excavated soil backfill, more types of connectors, elbows original three-way fight at the required protective cemented station. has been newly developed slip off the elbow and tee main products are steel pipes, ductile iron pipe with water and fittings and building drainage W-type flexible cast iron pipe and fittings, accessories and boiler tubes grate accessories specialist. Companies in strict accordance with ISO9001: 2000 quality management system standard build quality system, use of advanced equipment and the latest technology at home and abroad casting products, provide users with reliable quality assurance. Products: the use of the production of seamless steel as a raw material for processing, in a relatively short period of time by a fine coarse seamless centrifugal ductile iron pipe, to the specifications required by customers. Quality ductile iron casting having low phosphorus, low sulfur, low manganese and other characteristics, several products were rated as excellent, Buyou, it was widely used precision casting large domestic enterprises. Companies to develop as a top priority, to upgrade the level of equipment and competitive strength, product quality as the fundamental survival of enterprises, the user as the business of God; to reform as a driving force to talent as a fundamental ductile iron pipe, Supported by the Culture forge ahead dn1600 ductile iron pipe, with the majority of users, the universal friend and mutually beneficial cooperation, join hands to seek common development and create brilliant tomorrow!
