Ductile Iron Universal Flange Adaptor
The Ductile Iron Universal Flange Adaptor offered by Qingdao Valtech Manufacturing Co., Ltd. is a cast‑iron fitting designed to join plain‑ended pipes in water, sewage and HVAC networks. It is produced from ductile iron (nodular cast iron / SG iron) and incorporates a sleeve and gland of the same material. The adaptor is supplied with bolts and nuts that can be electroplated zinc or hot‑dip galvanized, and it uses SBR or EPDM rubber gaskets for sealing. It meets the functional requirements of municipal and industrial pipeline projects and can be finished with fusion‑bonded epoxy or wet paint for corrosion protection.
Ductile iron provides a nodular graphite structure that delivers superior ductility compared with gray cast iron, a standard property valued in pipe‑fitting components. Typical pressure capability for this class of adaptor is up to 1.6 MPa, and standard size offerings cover DN 50 to DN 300, matching common pipeline dimensions. The use of EPDM gaskets is typical for applications requiring resistance to temperature fluctuations, while SBR gaskets are common for cost‑effective sealing. The adaptor’s bolt material is usually zinc‑electroplated or hot‑dip galvanised, providing additional corrosion resistance.
Project engineers in municipal water utilities, wastewater treatment plants and HVAC system contractors often select this adaptor for its robust construction and easy installation. Buyers should request the detailed drawing set, confirm the desired coating and ask for the supplier’s lead time and MOQ before finalising the purchase. The supplier indicates flexibility in order volume and can ship under FOB or CIF terms.

Sourcing Ductile Iron Universal Flange Adaptor from Qingdao Valtech Manufacturing Co., Ltd. - China Import Guide
Importers need to confirm that the adaptor’s material grade, coating and gasket type match the project specifications, and request the mill test certificate and coating thickness data to ensure EN‑GJS‑400‑15 compliance. Obtaining CAD drawings will help verify flange dimensions against existing equipment.
Shipping is usually arranged on FOB or CIF basis; buyers should clarify the port of loading, container size and any pre‑shipment inspections. Payment is commonly made by T/T in advance or via L/C, and the exact terms should be agreed upon based on order volume and the supplier’s credit policy.
