Ductile Iron Double Loose Flange Bend
The Ductile Iron Double Loose Flange Bend supplied by Qingdao Valtech Manufacturing Co., Ltd. is a cast‑iron fitting produced to BS EN 545 and ISO 2531 specifications. It is available in nominal diameters from DN 40 up to DN 1 000 and can be ordered with pressure ratings of PN 10, PN 16, PN 25 or PN 40. The bend features a double loose‑flange connection and both the external and internal surfaces are treated with bitumen for enhanced corrosion protection. The minimum order quantity is one piece, as indicated in the listing.
Ductile iron used for the bend typically contains 3.5 % - 4.0 % graphite, giving a tensile strength around 350 MPa and a density of 7.2 t/m³, which is standard for this alloy. In the pipe‑fitting market a wall thickness of 6 mm for DN 40 up to 25 mm for DN 1 000 is common, providing the necessary strength for the selected pressure class. The bitumen coating is a conventional method to guard against external moisture and internal water‑borne aggressors, and it aligns with typical practices for water‑supply infrastructure. The product can be supplied in a plywood case or on a pallet, matching standard export packing.
These bends are installed in municipal water distribution networks, irrigation schemes and industrial fluid transport lines, and are purchased by utility companies, civil‑engineering contractors and system integrators. Qingdao Valtech offers L/C or T/T payment options and can arrange shipment from Qingdao Port, though exact lead times and freight terms should be confirmed with the supplier. Prospective buyers are encouraged to request the manufacturing test report and to verify the bitumen coating thickness before finalising the order.

Sourcing Ductile Iron Double Loose Flange Bend from Qingdao Valtech Manufacturing Co., Ltd. - China Import Guide
Importers should first verify that the supplied bend conforms to the specified DN size, pressure class and bitumen coating thickness, and request the mill test certificate and coating inspection report. Confirm that the product is produced at the Qingdao facility in Shandong Province and that the class of ductile iron (SG 40/50) matches project requirements.
Shipping from Qingdao Port is usually arranged under FOB or CIF terms; buyers need to agree on the exact Incoterm, confirm container loading plans and ask for an estimated lead time, which can vary with size and any custom surface treatment. Payment can be made via sight L/C or telegraphic transfer after the bill of lading is issued, but the supplier’s response rate suggests that early communication is essential to lock in terms.
To ensure quality, a pre‑shipment inspection focusing on dimensional accuracy, wall thickness and coating adhesion is recommended. Obtain the third‑party inspection report together with the certificate of conformity before the cargo departs. Maintaining these verification steps will help secure reliable delivery of the ductile‑iron bend for water‑infrastructure projects.
