Ductile Iron Fittings Double Flange Bend
The Double Flange Bend is a ductile‑iron fitting designed for water transmission and drainage pipelines. It is cast from spheroidal graphite iron and conforms to BS EN545 and ISO 2531 standards. The product is offered in four bend angles - 90°, 45°, 22.5°, and 11.25° - and covers nominal diameters from DN40 up to DN2600. All dimensions are listed in the supplier’s catalogue and match the stated size range.
The ductile‑iron matrix provides high tensile strength and good ductility, which is typical for municipal water infrastructure. Each fitting receives a bitumen coating on both the interior and exterior surfaces, a common corrosion‑resistant treatment for underground installations. In the industry, similar fittings are frequently supplied in the same standard grades and are compatible with polyethylene or steel pipe systems. The coating thickness is not specified by the supplier but follows standard practice of 0.5‑1 mm.
Typical applications include municipal water supply networks, industrial cooling loops and large‑scale irrigation projects. Buyers such as construction contractors, utility companies and engineering firms usually request OEM or ODM support, which the supplier lists as available. The fittings are shipped in plywood cases or on pallets, and the supplier accepts L/C or TT payment. Minimum order quantity is one piece, allowing small‑scale pilots as well as bulk procurement.

Sourcing Ductile Iron Fittings Double Flange Bend from Qingdao Valtech Manufacturing Co., Ltd. - China Import Guide
Before placing an order, verify that the fitting dimensions, angle and size match the project specifications and that the bitumen coating meets the required corrosion‑resistance level. Ask the supplier to supply material test certificates and, if necessary, a mill test report to confirm the ductile‑iron grade. Confirm that the product conforms to BS EN545 or ISO 2531 as claimed.
Logistics for these fittings usually involve sea freight from Qingdao ports. The supplier mentions L/C or TT payment terms and does not state a specific lead time, so buyers should ask for an estimated production and shipping schedule. Clarify the Incoterm to be used - commonly FOB Qingdao - and agree on any freight forwarder arrangements early in the negotiation.
Quality assurance is critical for infrastructure components. Request a pre‑shipment inspection covering dimensional tolerance, coating thickness and a hydrostatic pressure test. Obtain the inspection report together with the mill test certificate and warranty documentation before acceptance of the shipment. These steps help ensure the fittings meet the performance expectations of municipal or industrial water projects.
