T h = T b = Thickness after deducting mill tolerance from nominal pipe thickness or ordering thickness of run and branch pipe respectively

Β = Angle between axes of the branch and header or run pipeĭ 1 = Effective length removed from the run or header pipeĭ 2 = Half-width of the reinforcement zoneĭ h = Outside diameter of run or header pipe Let’s see the nomenclature as per para 304.3.3 below-Ī 1 = Area removed from the header or run pipeĪ 2 = Extrathickness available in the header pipeĪ 3 = Extrathickness available in the branch pipe

The amount of reinforcement or strength required to sustain the pressure is determined in accordance with para. Unless the wall thickness of the pipe is sufficient to sustain the pressure, it is necessary to provide added reinforcement pad.

Reinforcement Pad Thickness Calculationįabricated Branch Connection NomenclatureĪ pipe having a fabricated or welded branch connection is weakened by cutting out some area from the header pipe to fit the branch pipe onto it.
