ASME B31.8 - Reinforcement of Weld Branch Calculation (Demo)

Branch connections may be made by welded connections for pipeline systems designed in accordance with ASME B31.8. This tool was developed based on ASME B31.8 to help you determine if a reinforcement member is required. If yes, this tool can also verify your design to ensure it meets the minimum requirements of welded branch connection reinforcement.
