Stainless Steel Conical Union 316
AISI 316 welded conical unions for demountable stainless joints in chloride-rich or more corrosive process environments. Same cone-seat, maintenance-friendly design as 304 unions, with improved corrosion resistance for coastal, chemical, and hygienic duty. Quoted and sold per piece.

Applications & Selection Guide
Stainless steel conical unions in AISI 316 — the higher-alloy version of the DIN-style welded union with conical metal-to-metal seat, for demountable joints on welded 316/316L lines.
Specify 316 unions where chlorides, seawater atmosphere, or aggressive process media rule out 304: marine installations, chemical dosing, brine and coastal water treatment. Mixing grades at a demountable joint invites galvanic and crevice issues, so match the union grade to the line. Sizes are listed in the table above.
Quoted and sold per piece (complete set). Send size, quantity, and destination in a quote request for pricing and availability.
