Ductile Cast Iron Dismantling Joints
The Ductile Cast Iron Dismantling Joints supplied by Qingdao Valtech Manufacturing Co., Ltd. are precision‑engineered flange adapters designed for water, wastewater and industrial pipeline systems. They are cast from nodular graphite iron conforming to Grade 500‑7 as defined in ISO 1083, providing high strength and ductility. The joints accommodate axial movement and angular deflection while maintaining a leak‑free seal across sizes from DN50 to DN1200. The product originates from the manufacturing facilities in Qingdao, Shandong Province, China.
These joints are commonly specified under ISO 2531 and EN 545 standards, which set requirements for ductile iron pipe fittings. Typical pressure rating for this class of fittings is PN16, and standard operating temperatures range from - 20 °C to 120 °C. The corrosion‑resistant finish applied to the casting extends service life in aggressive environments. Manufacturers often offer a typical weight of about 5 kg for a DN100 joint, giving buyers a reference for handling and transport.
The components are sought after by water‑utility companies, municipal engineering firms and contractors involved in large‑scale infrastructure projects. While the listing mentions flexible minimum order quantities, exact MOQ, lead times and pricing are not disclosed and must be confirmed with the supplier. Prospective buyers should discuss packaging, shipping terms and any required certifications such as ISO 9001 before finalising the purchase.

Sourcing Ductile Cast Iron Dismantling Joints from Qingdao Valtech Manufacturing Co., Ltd. - China Import Guide
Before ordering, confirm that the joints meet the required ISO 1083 grade and that the supplied size matches your pipeline specifications. Request material test reports, hardness values and a certification of compliance with ISO 2531 or EN 545 to ensure suitability for your project. Verifying the corrosion‑resistant coating type and its thickness will help prevent premature failure in aggressive service conditions.
Discuss shipping arrangements with the supplier, specifying whether FOB from Qingdao Port or CIF to your destination port is preferred. Since lead times are not listed, ask for an estimated production schedule and transit duration to align with your construction timeline. Payment terms such as a documentary letter of credit or advance payment should be negotiated and documented in the sales contract.
Arrange a third‑party inspection at the factory to check dimensional accuracy, surface finish and the integrity of the dismantling mechanism before dispatch. Ensure that the commercial invoice, packing list and certificate of origin are prepared in accordance with your country’s customs requirements. Obtaining a final test report confirming pressure rating and temperature performance will provide additional assurance of product quality.
