The model 50 Flarweld access fitting body is designed to be welded directly to the pipe or vessel. The corrosion access fitting incorporates a radius to match the curvature of the pipe or vessel, with a maximum 1/16” weld gap.

It also incorporates a thick body to provide adequate branch reinforcement area to help strengthen the weld joint. It is the most popular type of corrosion fitting mounting configuration.
