Flexible Ductile Iron Drainage Pipe
The flexible ductile iron drainage pipe from Hebei Tongmao Pipeline Equipment Manufacturing Co., Ltd is manufactured from nodular cast iron conforming to ISO 1083/400-15 or 500-7 grades. The pipe features rubber-gasketed flexible joints designed to absorb ground movement, making it suitable for seismic zones and unstable soils. It is produced for gravity-flow systems in sewage, stormwater, and subsurface drainage applications.
Available in diameters from DN80 to DN600, the pipes meet ISO 2531 and EN 545 standards for internal and external corrosion resistance. The internal surface is centrifugally lined to ensure a smooth bore, reducing friction loss and improving flow efficiency. The external coating is typically bituminous or epoxy, providing protection against soil and groundwater corrosion. These pipes are not pressure-rated for pumped systems and are intended for gravity flow only.
This product is used in municipal infrastructure projects, industrial wastewater plants, and large-scale residential developments across Southeast Asia, Africa, and the Middle East. Buyers include civil engineering contractors, government procurement agencies, and pipeline distributors. Pipes are exported in timber-crated bundles, with each crate holding 4 to 12 lengths depending on diameter. Minimum order quantities and lead times are not stated and must be confirmed directly with the supplier.

Sourcing Flexible Ductile Iron Drainage Pipe from Hebei Tongmao Pipeline Equipment Manufacturing Co., Ltd - China Import Guide
Before ordering, verify the exact grade of ductile iron (400-15 or 500-7), the type of external coating, and the gasket material. Request mill test certificates for each batch and confirm the pipe wall thickness matches ISO 2531 tables for the selected diameter. Do not accept pipes without batch numbers or traceable documentation.
Lead time and Incoterms are not stated. Buyers must confirm whether FOB Tianjin or CIF destination is offered, and whether timber crates are included in the price. Ask for the number of pipes per crate and total weight per container. Payment terms are typically 30% advance, 70% against copy of BL. Confirm if container loading is supervised and if photos are provided pre-shipment.
Conduct a pre-shipment inspection for coating integrity, joint alignment, and absence of cracks or casting defects. Use a hammer test on the pipe surface to detect internal voids. Request a certificate of conformity for the rubber gaskets and ensure each crate is labeled with diameter, length, batch number, and production date. Retain samples for field testing if the project is critical infrastructure.
