Import Di Pipe Fittings, Double Flanged Hatch-Boxes. — Buy in wholesale FOB from Supplier in China

These double flanged hatch-boxes are manufactured from ductile iron, conforming to ISO2531, BS EN545, BS EN598, AWWA C219, AWWA C110, and ASME B16.42 standards. The fittings are designed for pressurised water and wastewater systems, with operating temperature limits from -40°C to 125°C. Internal linings include cement mortar, sulphuric resistance cement, or combinations with epoxy, ensuring corrosion resistance in aggressive environments. External coatings range from zinc and bitumen to metallic zinc with dual epoxy layers, selected based on exposure conditions.

Ductile iron grade GGG-40 is used as standard, providing tensile strength above 400 MPa and elongation above 10%, consistent with international norms for pressure pipe fittings. The double flange design allows secure bolted connections without welding, reducing installation time and field risks. Packaging is plastic film over palletised units, suitable for sea freight and bulk handling. These fittings are not intended for high-vibration or seismic zones without additional support, as per standard engineering practice.

Buyers in municipal water utilities, wastewater treatment plants, and infrastructure contractors in Southeast Asia, Africa, and Latin America commonly source these fittings for pipeline rehabilitation and new network expansion. Trade terms are typically FOB China port, with minimum order quantities negotiated per project scale. Lead times depend on production scheduling and coating availability. Buyers should confirm coating thickness, lining adhesion, and pressure testing certificates before shipment.
