Ductile iron pipe
Vortex Qingdao Co., Ltd. offers ductile iron pipe manufactured from nodular graphite iron conforming to ASTM A536 Grade 65-45-12. The pipes are produced in accordance with ISO 2531 and AWWA C151 specifications for pressure classes up to PN35. Available diameters cover DN80 through DN2000, with wall thicknesses selected to meet the required pressure rating. Each pipe is classified under HS Code 7303.00 and is supplied with dimensional and hydrostatic test certificates.
Joint configurations include socket-and-spigot as well as flanged connections, allowing flexibility in installation methods. A corrosion-resistant coating is applied as a standard finish, extending service life in water and wastewater environments. Typical industry practice for this pipe class uses a nominal wall thickness ranging from 5 mm for DN80 to 30 mm for DN2000, which aligns with the supplier’s catalogue. Standard pipe lengths are 6 m, with tolerances of ±0.5 mm on diameter and ±5 mm on length.
These pipes are commonly selected by municipal water utilities, irrigation scheme contractors, and industrial fluid-transport engineers. Vortex Qingdao lists the product for export with FOB or CIF options, but exact minimum order quantity and lead time are not disclosed in the public data. Prospective buyers should verify the coating type, pressure class, and certification documents directly with the supplier before placing an order.
