These double flanged hatch-box fittings are manufactured from ductile iron to meet international standards including ISO2531, BS EN545, BS EN598, AWWA C219, AWWA C110, and ASME B16.42. The fittings are designed for pressurized and gravity flow systems handling potable water, sewage, and wastewater. Dimensions and flange thicknesses align with the nominal pipe sizes specified in these standards, ensuring compatibility with standard ductile iron pipe systems.
Internal linings are available in four variants: cement mortar, sulphuric resistance cement, sulphuric resistance cement with epoxy, and H.A. cement. These provide corrosion resistance tailored to aggressive media. External coatings include zinc and bitumen, zinc with dual epoxy layers, metallic zinc with etching primer and dual epoxy, or zinc with polyurethane. The coating options are selected based on soil conditions and exposure, with metallic zinc and epoxy systems offering extended service life in corrosive environments.
These fittings are commonly purchased by municipal water utilities, wastewater treatment contractors, and infrastructure developers in regions with aging pipe networks. They are shipped in plastic film wrapped on wooden pallets, with no individual boxing. Bulk orders are typical, and lead times vary based on production scheduling. Buyers should confirm flange bolt hole patterns and lining selection at order stage, as variations affect installation compatibility and system longevity.

Before placing an order, verify the exact internal lining and external coating combination required for your system’s media and environmental conditions. Confirm the pressure class and flange bolt pattern match existing piping. Request material test reports for the ductile iron and coating certification documents, especially if used in potable water or industrial wastewater. Do not assume compliance based on standard names alone.
Lead time is typically 30 to 45 days after order confirmation, but this is unconfirmed by the supplier. Incoterms are not stated; buyers must specify whether FOB, CIF, or EXW applies. Payment terms are not listed - common arrangements include 30% advance with 70% against shipping documents. Confirm packaging integrity requirements, as pallets must be moisture-sealed for ocean transport.
Upon arrival, inspect fittings for coating damage, flange warping, or lining cracks. Use a thickness gauge to verify zinc and epoxy layers meet minimums. Conduct a visual inspection for internal lining defects under light. Retain samples from each batch for independent lab testing of tensile strength and lining adhesion. Ensure the supplier provides a packing list, test certificates, and a commercial invoice matching the order exactly.
