Short answer: HXSCO supplies pipe flanges — weld-neck, slip-on, blind, socket-weld, lap-joint and orifice — in carbon, stainless, alloy and duplex steel to ASME B16.5 / B16.47, matched to your pipe schedule and facing so the joint is correct from the first bolt-up.

Flanges We Supply
We stock the full flange programme: weld-neck for high-pressure and cyclic duty, slip-on for economy, blinds for isolation and testing, socket-weld for small-bore high-integrity joints, lap-joint with stub ends for frequent stripping, and orifice/RTJ for metering and high sealing. Our flange line pairs directly with Steel Pipe Supplier, Stainless Steel Pipe Supplier and the butt-weld programme in Pipe Fittings Supplier; sizing follows Steel Pipe Fittings Flanges Guide.
Materials, Facing & Schedule
Materials span carbon and alloy per Astm A53 Vs A106 Steel Pipe, stainless 304/316 and duplex for corrosive service — the duplex step is in Duplex Stainless Supplier. We match the flange to your nominal pipe size, schedule, facing (RF, FF, RTJ) and end-prep, using the method in How To Measure Steel Pipe Size; for coated or black systems see Galvanized Steel Supplier.
Applications & Quality
Flanges carry the same corrosion and galvanic concerns as the pipe they join — plan with Galvanic Corrosion Guide — so we certificate every lot with material and heat number, PMI where specified, and mill documentation per Mill Test Certificate Guide, packed for export with bolt kits and fumigation marks on request.
