Product Description

CARBON STAINLESS ALLOY STEEL LONG WELDING NECK FLANGE

The long wn flanges connection is the lightest and most economical of FCI standard connections I offered for use where a minimum of reinforcing area is required. Long Weld Necks have a uniform barrel outside diameter that provides a nut relief clearance between the connection neck and the nut.

Lengths can be increased to allow for any offset, "hillside" or tangential location attachment on pressure vessel shells or heads. Contoured bottoms are available upon request.
