ISO2531 Ductile Iron Pipe Class K9/C40/C30/C25
ISO2531 ductile iron pipes from Jincheng Tianyi Foundry Co., Ltd. are engineered for municipal water supply, irrigation and sewage transmission, meeting ISO 2531, EN545 and EN598 standards. The pipes are supplied in pressure classes K9, C40, C30 and C25, with diameters spanning DN80 to DN2600 and standard lengths of 6 m for bulk shipments or 5.7 m for containerised loads. Joint types include push-on Tyton, K-type and self-restrained designs to ensure leak-free connections in high-pressure systems.
The material is ductile iron (SG iron), offering higher strength and lighter weight than grey iron, with corrosion resistance and minimal flow resistance for long service life. Internal lining is cement mortar per ISO 4179, while external protection includes zinc coating of at least 130 g/m² and bitumen painting of at least 70 µm, both to ISO 8179. Gaskets are NBR, natural rubber, SBR or EPDM rubber rings conforming to ISO 4633, with custom coatings like zinc-aluminium alloy or PU available on request.
These pipes are primarily used by water infrastructure contractors and distributors for municipal and industrial projects. Packaging options include bundling with steel belts or bulk shipment, with accessories such as 100% SBR rubber rings included. The pipes are inspected using automatic equipment to ensure consistency, making them a reliable choice for large-scale utility installations.

Sourcing ISO2531 Ductile Iron Pipe Class K9/C40/C30/C25 from Jincheng Tianyi Foundry Co., Ltd. - China Import Guide
Before ordering, verify the pressure class and diameter compatibility with your project requirements, as these directly impact the pipe’s performance and longevity. Confirm the joint type and gasket material to ensure compatibility with your existing system and environmental conditions, particularly for underground installations.
Logistics should be discussed with the supplier to determine the most cost-effective shipping method, whether bulk or containerised. Clarify Incoterms such as FOB or CIF and payment terms like L/C or T/T, as these will affect your total landed cost. Lead times may vary based on order volume and customisation requests.
Quality checks should include verifying the internal lining thickness and external coating weight, as these are critical for corrosion resistance. Request inspection certificates for material composition and joint integrity. Ensure all documentation, including ISO compliance certificates, is provided to avoid delays during customs clearance.
