Ductile Iron Drainage Pipe
The Ductile Iron Drainage Pipe is produced from EN‑GJS‑500‑7 (GGG 50) ductile iron and conforms to ISO 2531, EN 545 and BS EN 598 standards. It is supplied in nominal diameters from 80 mm up to 1600 mm and is available with socket, spigot and flanged joint configurations. Pressure classes cover PN10 through PN40, allowing the pipe to handle a broad selection of hydraulic loads in both water supply and sewage applications.
Ductile‑iron pipe of this grade typically exhibits a tensile strength of at least 350 MPa and a density around 7.1 t/m³, providing a robust alternative to steel while retaining good ductility. Standard wall‑thickness tables prescribe thicknesses from roughly 4 mm for the smallest diameters to 30 mm for the largest, ensuring sufficient hoop stress resistance. The material’s inherent corrosion resistance is enhanced by the iron‑silicon matrix, and the pipe can be laid in diverse soil conditions without extensive backfill.
Clients such as municipal utilities, civil‑engineering contractors and industrial plant developers select this pipe for gravity‑flow drainage networks, culvert installations and potable‑water distribution. While the supplier does not publish a fixed MOQ or price list, payment terms are negotiated directly with the buyer, and packaging for bulk orders is typically handled on wooden pallets or steel drums. The product’s versatility and compliance with multiple international standards make it suitable for both above‑ground and underground installations.

Sourcing Ductile Iron Drainage Pipe from Hebei Tongmao Pipeline Equipment Manufacturing Co., Ltd - China Import Guide
Prior to ordering, confirm that the pipe dimensions, wall‑thickness schedule and pressure class match the design specifications of your project. Ask for the latest mill test reports and certificates of conformity to ISO 2531, EN 545 and BS EN 598, and verify that the joint type selected aligns with installation requirements.
Discuss logistics early: agree on Incoterms such as FOB Cangzhou or CIF destination port, clarify lead‑time based on current production queues, and negotiate payment conditions that suit both parties. Verify the packaging format - whether wooden pallets or steel drums - to ensure compatibility with your transport and storage infrastructure.
Arrange an independent inspection either at the factory or upon arrival to validate dimensional tolerances, wall‑thickness uniformity and coating integrity. Request a full set of documentation, including the mill test report, material analysis and any applicable third‑party certification, to streamline customs clearance and subsequent quality assurance processes.
