Red Epoxy Coating Ductile Iron Flange Pipe One End Flange Other End Spigot
Flanged Ductile Iron Pipe:
Flange products are available within the range of DN80 to DN2600, with jointing in such forms as T, K, K2, NI, NⅡ, MJ and ES. The annual production capacity includes over 15,000 tons of straight pipes and special spheroidal graphite cast iron pipe fittings. Xingfeng’s achievements attribute to its market recognition, including the accolades by a number of national, ministerial and provincial honors.conform to the international standards such as the ISO2531, BSEN545 and the American standards ANSI/AWWI C153, C110and GB13295.The Standard Operating Procedures (SOP) has been set up for the molding process, from cultivation, molding, splicing to coating and drying. Likewise the implementation to a series of processes including packing, spheroidizing and vacuum casting etc, a thorough inspection comprises of various tests including metallographic examination, spectral analysis, chemical analysis, tensile experiment, hardness testing, hydrostatic test, ultrasonic wall thickness measurement etc is performed on each and every fittings to ensure the superior product quality. Pipe wall thickness compliance shall be demonstrated by the manufacturer; a combination of various means may be used, such as pipe weight control; direct wall thickness measuring or gauging by suitable equipment, such as mechanical or ultrasonic equipment. The frequency of testing is related to the system of production and quality control used by the manufacturer.
Packing: in wooden box or pallet, or in bulk
Shipment: in bulk or container

Ductile iron pipeline systems, including pipes, fittings, accessories and joints, consist of various materials.When used for conveying water intended for human consumption, the materials in contact with the water shall meet the relevant requirements of the national standards or regulations in the country of use with respect to effect on water quality. When used under the conditions for which they are designed, in permanent or in temporary contact with water intended for human consumption, ductile iron pipes, fittings and their joints shall not have detrimental effects on the properties of that water for its intended use.
There are lots of qualified managers and technicians, and a well-trained team of after-sales service, which provides all services of manufacture, package, transportation and installation. We are looking forward to cooperating with friends from abroad and home creating a brighter future.
