The product categories of ductile iron pipes and fittings mainly include: water supply pipes, drainage pipes, thermal pipes, polyfluoroester lined pipes, argon resin lined pipes, epoxy ceramic lined pipes, PE lined pipes, zinc-aluminum alloy pipes, jacking pipes, drag pipes, self-anchored pipes, sewage pipes and matching pipe fittings.

This EN598 sewage ductile iron pipe has a zinc plus infrared anti-corrosion coating and a high-alumina cement inner anti-corrosion coating with good wear resistance and can cope with special soils and conveying media.

The lengths of our towing ductile iron pipes are 8.15m, 6.0m, 5.7m, can be customized according to customer requirements.

The self-anchored ductile iron pipe adopts a special mechanical design to weld the ring to the socket end to achieve reliable anchoring performance, while retaining the flexibility of the joint, with good flexural performance, which can replace the function of the constraint block and realize the design without constraint blocks.

The sealing principle of the GT type interface of GT type ductile iron pipe is similar to that of the T type interface. As the internal pressure of the pipeline increases, the tighter the contact surface between the rubber ring sealing sleeve and the socket, the better the sealing effect.

The T-joint ductile iron pipe has a simple structure, is easy to install and has good sealing performance.

Prefabricated insulated ductile iron Pipe integrates ductile iron’s strength with pre-installed polyurethane insulation and anti-corrosion layers. It minimizes heat loss for hot water or district heating, withstanding -40℃ to 130℃ temperatures. The prefabricated design skips on-site insulation work, cutting installation time by 60%. Used in municipal heating, industrial fluid transport, it resists corrosion and has a 50+ year service life. Applied in Harbin’s cold-region projects, it ensures stable operation in harsh conditions.

Guoming's Sewage Pipe, typically ductile iron-made, is designed for sewage transport. It resists corrosion from acidic/alkaline wastewater and hydrogen sulfide-induced "crown corrosion" . With reliable gasket seals, it prevents leaks and secondary pollution . Suitable for municipal drainage, industrial wastewater, and residential sewage systems, it handles gravity/pressure flow efficiently . Its robust structure ensures over 50 years of service, lowering maintenance costs for urban and industrial projects .

Special Coating Pipe is a ductile iron pipe developed by Guoming Ductile Iron Pipes Co., Ltd. to meet different customer needs, with various high-performance internal and external anti-corrosion coatings. Its coatings include zinc-aluminum alloy external anti-corrosion coating, polyurethane internal and external coating, epoxy resin layer, ceramic coating, etc. It is applicable to wet areas like ponds and swamps, saline-alkali land, clay with poor air permeability, industrial parks and other scenarios, effectively resisting corrosion and ensuring long-term stable use of the pipe .

Product Summary: PE Liner Pipe is a new type of ductile iron pipe of Guoming Ductile Iron Pipes Co., Ltd. It combines the advantages of ductile iron pipes and polyethylene pipes, with good sanitary performance and no easy internal-external delamination. It meets direct drinking water requirements, resists corrosion from special media like seawater and urban sewage, and is mainly used for drinking water and direct drinking water transportation, supporting Guoming's pipeline system.
