SG Iron Unions are precision‑cast ductile iron pipe fittings produced by Kalyan Steel Centre in India. The fittings are made from spheroidal graphite cast iron, conforming to Grade 400‑15 / 500‑07 as stated in the supplier data. They are supplied in both threaded and socket‑weld configurations for connection to pipelines. The casting process controls carbon and magnesium levels to achieve the stated material properties.
Typical ductile‑iron unions of this grade exhibit tensile strengths around 400 MPa and impact energies near 30 J, which meet ASTM A536 and ISO 1083 requirements common in the industry. Standard nominal sizes for such unions range from DN 50 to DN 500, allowing use in water distribution, oil‑gas, and industrial piping. Kalyan Steel Centre uses spectrometer analysis to verify composition and reports compliance on request.
Importers often select these unions for municipal water networks, construction projects, and energy‑sector pipelines. Trade terms such as minimum order quantity, price, and lead time are not disclosed in the listing and should be confirmed directly with the supplier. Buyers should also agree on Incoterms and payment conditions before finalising the purchase.

Before placing an order, importers should verify that the supplied fittings match the stated Grade 400‑15 / 500‑07 and that the supplier can provide a mill test report or certificate of compliance with ASTM A536 and ISO 1083. Requesting a sample or detailed technical data sheet helps confirm dimensions, thread standards, and pressure ratings. Confirm that the supplier’s "harbor" trust tier reflects a vetted business and ask for references if needed.
Logistics must be clarified, including the preferred Incoterm (e.g., FOB Mumbai or CIF destination), expected lead time for casting and shipment, and the payment schedule acceptable to both parties. Because the listing does not disclose MOQ or price, the buyer should negotiate these points directly and obtain a pro‑forma invoice. Shipping bulk unions usually requires wooden crates; discuss container load plans and any special handling requirements.
Quality assurance should include a third‑party inspection at the factory or before loading, focusing on dimensional checks, wall thickness, and visual defects. Request hydrostatic testing results for the pressure class ordered, and ensure the inspection agency can provide a final report. Retain all certificates and test documentation for customs clearance and downstream project verification.
