A blind flange is a solid, round plate with full bolt-hole drilling and no central bore, designed to seal the end of a pipe, vessel, or equipment in high-pressure systems. Highborn Flanges & Fittings India Pvt Ltd manufactures these to ANSI/ASME B16.5 and B16.47 standards, covering pressure classes from 150# to 2500#. The flanges are forged or cut from plate stock, ensuring structural integrity under extreme thermal and mechanical loads.
Material options include carbon steel ASTM A105, stainless steel 304 and 316, and alloy steel ASTM A182. These materials are selected based on corrosion resistance, temperature tolerance, and service environment. Carbon steel is typical for general industrial use, while 316 stainless is standard in chloride-exposed applications. The outer diameter, thickness, and bolt hole alignment are controlled to within standard tolerances for flange mating surfaces, ensuring leak-free sealing with gaskets.
These flanges are commonly purchased by engineering contractors in oil and gas, petrochemical plants, and water treatment facilities for isolation during maintenance or pressure testing. Buyers typically require certification of material traceability and dimensional compliance. Packaging is in wooden crates with rust inhibitors, and shipment is FOB Mundra or Nhava Sheva. MOQ and lead time vary by size and grade; confirm directly with the supplier.

Before placing an order, verify the material grade and certification against your project specifications. Request Mill Test Reports for carbon steel and stainless steel flanges to confirm chemical composition and mechanical properties. Ensure the supplier can provide traceability from heat number to finished product, especially for high-pressure systems where material failure risks are high.
Confirm Incoterms, lead time, and packaging details directly with the supplier. Typical lead time is 4 to 8 weeks depending on size and grade. FOB Mundra or Nhava Sheva are common ports. Payment terms are usually 30% advance and 70% against shipping documents. Ask if flanges are packed with rust inhibitors and whether wooden crates meet ISPM-15 for international shipping.
Inspect flanges upon arrival for surface defects, correct dimensions, and bolt hole alignment. Use calipers and pin gauges to verify outer diameter and hole spacing against the ASME B16.5 tables. Check for markings indicating material grade, pressure class, and manufacturer. Retain inspection records and request third-party inspection if the flanges will be used in safety-critical systems.
