Schedule60 300LB RF A105 WN flange

Our Schedule60 300LB RF A105 WN flange applied to pipe connection with carbon steel A105. 

Welding Neck Flanges (RFWN Flange) are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.

This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
