SG Iron Flanges
Kalyan Steel Centre supplies SG Iron Flanges manufactured from spheroidal graphite iron, commonly known as ductile iron. The casting material is supplied in Grade 400‑12 and Grade 500‑07, providing a balance of tensile strength and ductility suitable for demanding pipelines. Flanges are offered in round, square and oblong configurations and are produced to comply with ASTM A395 and ISO 2531 specifications. Each unit is cast to precise dimensions, allowing direct integration into water, oil and gas piping systems.
Compared with conventional grey cast iron, the spheroidal graphite structure delivers higher impact resistance and better machinability, which industry users value for long‑term service. Typical pressure classifications for these flanges range from PN16 to PN25, while temperature capability spans - 20 °C to 250 °C, matching standard requirements for municipal and petrochemical installations. Standard bolt‑circle diameters fall between 150 mm and 300 mm, and flange thickness usually varies from 20 mm to 50 mm, providing flexibility for a wide span of pipe schedules. The casting process includes heat treatment and dimensional inspection to ensure conformity with the cited standards.
Importers and industrial buyers such as water‑treatment facilities, chemical plants and power‑generation projects commonly source these flanges for new builds or retrofits. Kalyan Steel Centre offers flexible minimum order quantities and can arrange packaging in wooden crates or steel pallets depending on shipment size. Trade terms include FOB or CIF options, and the supplier can provide ISO and SGS certificates upon request to demonstrate compliance. Payment methods are negotiated per order, allowing buyers to align financing with project milestones.

Sourcing SG Iron Flanges from Kalyan Steel Centre - India Import Guide
Before placing an order, verify that the flanges are produced from spheroidal graphite iron in the stated grades and that the supplied technical drawings match the required dimensions, pressure class and bolt‑circle pattern. Request the most recent ISO and SGS test reports to confirm compliance with ASTM A395 and ISO 2531, and confirm any custom size specifications in writing.
Logistics should be clarified early: agree on Incoterms such as FOB Mumbai or CIF to your destination port, ask the supplier for estimated lead time based on current production capacity, and discuss payment terms that align with your project cash flow. Confirm whether the shipment will be consolidated in wooden crates or steel pallets and whether container loading plans meet your schedule.
Arrange a third‑party inspection at the factory or upon arrival to verify material grade, dimensional tolerances and surface finish. Obtain a mill test certificate and a packing list before release of the goods. Ensure that any required customs documentation, such as a certificate of origin and conformity declaration, is prepared in advance to avoid clearance delays.
