The SG Iron Couplings offered by Kalyan Steel Centre are fabricated from ductile iron conforming to EN‑GJS‑400‑15, also identified as SG Iron Grade 400‑15. Each coupling is supplied in nominal diameters ranging from DN50 up to DN600 and is classified under HS code 7307.19 for customs purposes. The product description highlights superior tensile strength and impact resistance compared with conventional gray iron, making it suitable for high‑pressure pipelines. Kalyan Steel Centre lists these couplings for global export without specifying minimum order quantities or pricing, inviting buyers to request a formal quote.
Ductile iron of the EN‑GJS‑400‑15 grade typically exhibits a tensile strength around 400 MPa and an impact energy of roughly 20 J, values that are standard for this material class. The material’s spheroidal graphite structure provides weight savings while maintaining mechanical robustness, a factor that many municipal and industrial projects consider when selecting pipe fittings. In the industry, such couplings are often finished with a machined bore to ensure alignment and are sometimes supplied with optional zinc coating for added corrosion protection. These characteristics align with the requirements of water transmission, sewage treatment, and oil‑and‑gas pipeline applications.
Primary users include municipal water authorities, sewage treatment facilities, and contractors involved in oil and gas infrastructure. Buyers typically assess the suitability of the couplings for their pressure class and verify that the supplied size matches the pipeline design. As the listing does not disclose lead times, incoterms, or payment conditions, interested importers should contact Kalyan Steel Centre directly to confirm trade terms and arrange sampling if required.

Before placing an order, verify that Kalyan Steel Centre can provide a mill test certificate confirming the EN‑GJS‑400‑15 grade and any additional material test reports. Request documentation on the manufacturing process, heat‑treatment records and, if applicable, the results of impact testing to ensure the couplings meet the required mechanical properties. Confirm that the supplied size and weight data align with your engineering specifications before finalising the purchase.
Import logistics should address the shipping method, typical lead times and the incoterm that will be applied. As the listing does not state an incoterm, buyers need to clarify whether FOB, CIF or another term is preferred and verify the associated freight costs. Payment terms are also not disclosed, so discuss whether a letter of credit, advance payment or other arrangement is acceptable to both parties.
Quality assurance is best supported by arranging a pre‑shipment inspection by a recognised third‑party agency. Inspectors should check dimensional tolerances, surface finish and any applied zinc coating, and compare the findings against the mill test certificate. Ensure that the final shipment includes a certificate of origin, the mill test report and, if requested, a conformity‑to‑standard declaration to facilitate smooth customs clearance.
