Ductile Iron Couplings
The Ductile Iron Couplings supplied by Kalyan Steel Centre are cast fittings made from nodular (SG) iron. They are offered in sizes ranging from DN50 to DN600, covering a broad spectrum of pipe diameters used in water, sewage and industrial pipelines. The couplings comply with ISO 2531 and EN 545 standards, providing a recognised benchmark for dimensional and material performance. This grade of ductile iron delivers higher tensile strength and better corrosion resistance than conventional grey cast iron.
SG iron, also known as nodular cast iron, typically exhibits tensile strength between 400 MPa and 600 MPa and a hardness of 180 HB to 250 HB, values that are standard for these applications. Typical pressure ratings for couplings of this class fall in the 10 bar to 25 bar range, and operating temperatures usually span - 20 °C to 120 °C. Standard packaging for export is on pallets or in cartons, with individual coupling weights commonly between 2 kg and 30 kg depending on size. These typical parameters help engineers select the right fitting for system design.
The couplings are widely used in municipal water distribution, wastewater treatment plants and industrial process piping, where reliable pressure containment is essential. Importers often request mill‑test reports and conformity certificates to verify compliance with ISO 2531 and EN 545 before acceptance. While flexible minimum order quantities and shipping options such as FOB or CIF are advertised, exact quantities, pricing and lead times must be confirmed directly with Kalyan Steel Centre.

Sourcing Ductile Iron Couplings from Kalyan Steel Centre - India Import Guide
Prior to ordering, confirm the exact nominal size, pressure rating and material grade required for your pipeline. Request the engineering drawing and a mill‑test report that demonstrates compliance with ISO 2531 and EN 545. Because the supplier’s response statistics are blank, establish a reliable contact person and secure written agreement on any custom dimensions.
Discuss the preferred Incoterm - FOB from the Mumbai port or CIF to your destination - and verify that the couplings can be loaded onto standard 20‑ft or 40‑ft containers. Ask for an estimated lead time based on the selected DN size and any post‑casting machining. Payment methods such as L/C or T/T are referenced, but the exact terms should be negotiated and documented before shipment.
Arrange for a third‑party inspection or request a pre‑shipment certificate covering chemical composition, tensile strength and hardness. Ensure that the packaging on pallets or cartons meets your handling and storage requirements, and that the weight per unit matches the typical range provided. Confirm that all relevant certificates, including ISO and any material test reports, will accompany the goods to facilitate customs clearance.
