Welders then compensate by putting more filler metal (thus, heat) into the joint to fill it. This added heat can lead to distortion and, with corrosion-resistant pipe like stainless steel, can reduce the corrosion-resistant qualities of the base metal. It can also lead to lack of penetration or excessive penetration.sp.info Non-Welded Piping Solutions for Oil and Gas Applications ...Apr 17, 2014 · Parker’s Dual Seal Flange Adapters improve the reliability of high vibration, high-shock hydraulic four bolt connections in critical oil and gas applications.
