- Standard Reinforcement Pad shall be Adequate for sustaining the internal pressure.
Standard Reinforcement Pad shall be of twice the Outside Diameter of Branch NPS and of same Material
& of same thickness, as that of the Header or Run Pipe.
For lower Branch sizes, use of Integrally Reinforced Branch Outlet Fittings is recommended.
X - Standard Reinforcement Pad shall NOT be Adequate. Also, further check is required for
ascertaining the VALIDITY of d1 and d2 values, which may exceed Dh. User's check is required.
This decision flag may also appear for NO size / data defined. User must check.
Standard Reinforcement Pad of twice the Outside Diameter of Branch NPS and of same Material
& of same thickness, as that of the Header or Run Pipe is found to be insufficient.
In such specific cases, use of either Tees (Equal / Unequal, as applicable) or Integrally Reinforced
Branch Outlet Fittings is recommended.
ASSUMPTIONS:
1. The Run or Header Pipe Diameter-to-Thickness Ratio (Dh/Th) shall be less than 100.
2. For Run or Header Pipe with the Ratio (Dh/Th) greater than or equal to 100, the Branch Pipe
Diameter (Db) shall be less than on-half (1/2) the Run or Header Pipe Diameter (Dh).
3. The Branch-to-Run Pipe Diameter Ratio (Db/Dh) shall NOT be greater than 1.0.
4. The Smaller Angle between the axes of Branch and Run shall be at least 45°.
5. The axis of the Branch intersects the axis of the Run.
NOTES:
1. The calculation for Reinforcement of Welded Branch Connections has been carried out based on
ASME B31.3 paragraph 304.3.3.
2. This Branching Table has been calculated for Header-to-Branch Angle of 90° Beta Angle only.
3. Calculated Available Area is inclusive of the Area Available in the fillet weld of minimum size, as defined in
ASME B31.3 paragraph 328.5.4.
