Large Diameter Flanges
Large Diameter Flanges are metal rings that join pipes, valves, pumps and other equipment in industrial pipeline systems. Highborn Flanges & Fittings India Pvt Ltd offers these flanges in Carbon Steel ASTM A105 and Stainless Steel grades 304 and 316. All sizes conform to ASME B16.5 and API standards for diameters above 24 inches (NPS 26‑60). The flanges are supplied in pressure classes 150, 300, 600, 900, 1500 and 2500 as required by the end‑use.
The product line includes both raised‑face and flat‑face designs, each equipped with a sealing gasket to prevent leaks. Dimensional tolerances are held within ±0.1 mm for flange thickness and bolt circle diameter, matching the typical requirements of heavy‑industry projects.

These flanges are commonly installed in offshore platforms, refineries, petrochemical complexes, water‑treatment plants and power‑generation facilities. Buyers often request custom configurations; Highborn can mill‑machine to specific dimensions on request. Pricing, minimum order quantities and lead times are not published in the listing and should be confirmed directly with the supplier.

Sourcing Large Diameter Flanges from Highborn Flanges & Fittings India Pvt Ltd - India Import Guide
Before placing an order for large diameter flanges from Highborn, importers should verify the exact material grade (ASTM A105, SS 304 or SS 316) and the pressure class required for the application. Request the latest mill test report and any applicable ISO 9001 certification to confirm compliance with ASME B16.5. Check that the flange dimensions, bolt hole pattern and face type match the engineering drawings, and confirm any custom machining tolerances in writing.
Highborn ships from the port of Mumbai or Nhava Sheva, so buyers should clarify the preferred Incoterm, such as FOB Mumbai or CIF destination. Lead times for standard sizes are typically 4‑6 weeks, but custom orders may require additional scheduling. Payment terms are not listed; common practice in the region includes a 30 % advance letter of credit followed by balance against documents. Importers must confirm the exact shipping schedule and any freight forwarding requirements with the supplier.
Upon arrival, the flanges should be inspected for dimensional accuracy, surface defects and proper gasket seating. An independent third‑party NDE inspection, such as ultrasonic testing, is recommended for pressure classes above 600. The supplier should provide a full set of documents including the mill test report, material certification, and a compliance declaration with ASME B16.5. Arranging a pre‑shipment inspection can further ensure that the product meets the project specifications before loading.
