18inch 150# Carbon Steel ASTM A105 RF Weld Neck Flange

  A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange. 18inch 150# Carbon Steel ASTM A105 RF Weld Neck Flange, typically manufactured from forging, are actually welded to pipes.

  The rim has numerous holes drilled into it that enables the flanged to be attached to a bolted flange. This design is far better because of the structural valve.
