About Highborn Flanges & Fittings India Pvt Ltd - Flanges Supplier in India

India based Highborn Flanges & Fittings India Pvt Ltd lists eight active flange products in its catalogue. The items include Blind Flanges, Orifice Flanges, Threaded Flanges, Long Weld‑Neck Flanges, Large Diameter Flanges, Slip‑On Flanges, Lap Joint Flanges and Sae Flanges, each identified with HS codes in chapter 73 such as 7307.99 for blind flanges and 7307.19 for several other types. Materials covered span carbon steel grades ASTM A105 and A350, stainless steel grades 304, 304L, 316 and 316L, and alloy steel ASTM A182, matching the specifications commonly required for pressure‑retaining equipment. The catalogue references the ASME B16.5 flange series and related dimensional standards, indicating compliance with widely accepted industry dimensions.

The supplier’s product list is organized by flange type and material, with HS codes that align with global customs classifications for steel pipe fittings. Carbon steel variants are described using ASTM A105, while stainless steel options reference 304/304L and 316/316L grades that meet typical corrosion‑resistance criteria for petrochemical and power sectors. Alloy steel entries cite ASTM A182, a standard for high‑strength, high‑temperature applications. No additional certifications are stated in the supplied facts, so buyers should verify compliance with ASME, API and ISO quality systems during the sourcing process.

Product Range and Specialties of Highborn Flanges & Fittings India Pvt Ltd

Highborn’s catalogue covers eight flange designs, each tied to specific HS‑7 codes: Blind Flanges (7307.99), Orifice, Threaded, Large Diameter, Slip‑On, Lap Joint and Sae Flanges (all 7307.19), and Long Weld‑Neck Flanges (7307.23). In the broader industry, these flange families are classified by pressure rating (Class 150‑2500) and connection type, with common grades such as ASTM A105 for carbon steel and ASTM A182 F22/F44 for alloy steel. Stainless steel flanges typically meet ASTM A240 specifications for 304/304L and 316/316L, providing corrosion resistance for offshore and chemical processing lines.

Typical industry specifications include dimensional tolerances defined in ASME B16.5, face finish options (raised‑face, flat‑face, ring‑type joint), and testing requirements such as hydrostatic pressure testing at 1.5 times the design pressure. Buyers often request mill test reports (MTR) and material certificates that confirm compliance with the cited ASTM grades. Packaging for these steel components generally involves wooden crates, steel drums or bulk pallets, sized to fit 20‑ft or 40‑ft containers for overseas shipment.

Trade and Export Information - Highborn Flanges & Fittings India Pvt Ltd

India is a leading exporter of steel pipe fittings, with flange shipments primarily destined for the Middle East, Southeast Asia, Europe and the United States. The HS‑7 chapter 73 codes used by Highborn align with customs requirements for steel fittings, and importers typically verify ASME B16.5 compliance, API 6A specifications for oilfield service, and ISO 9001 quality management certification. Common Incoterms include FOB Indian ports such as Mumbai or Kandla, and CIF to major hubs like Dubai, Singapore or Rotterdam.

Export logistics for flanges involve loading into 20‑ft or 40‑ft containers, with weight per container ranging from 12 t to 18 t depending on flange size. Buyers should anticipate customs inspections that may request material certificates, test reports and compliance declarations. Indian manufacturers often adhere to the Bureau of Indian Standards (BIS) requirements for steel products, although specific certifications must be confirmed with the supplier before order placement.

Sourcing from Highborn Flanges & Fittings India Pvt Ltd - Buyer Guidance

When sourcing flanges from Highborn, request mill test reports that list the exact ASTM grade, chemical composition and heat‑treatment condition for each item. Verify that the dimensions and pressure class match the ASME B16.5 schedule required for your project, and ask for a compliance statement for any relevant API or ISO standards.

Confirm the packaging format (crate, pallet or bulk) and whether the flanges will be pre‑painted or coated for corrosion protection. Clarify the minimum order quantity, typical lead time (often 4‑6 weeks for standard sizes), and the preferred Incoterm. Request a pre‑shipment inspection report if your procurement policy mandates third‑party verification.
