This spreadsheet is about calculation on Pipe reinforcement of:
where:
Pressure Design Straight Pipe (Run Pipe)
- STRAIGHT PIPE THICKNESS UNDER INTERNAL PRESSURE (tm) , mm.
Formula used are:
tm =[(PDo)/2(SE+PY)]+A and tm =(Pd+2SEA+2YPA)/2(SE+PY-P)
P | Internal Design Gauge Pressure, N/mm2. | ||||
Doh | Outside Diameter of Pipe, mm. | ||||
S | Stress Value for Material, N/mm2. | ||||
E | Quality Factor For Longitudinal Weld Joints in Pipes. | ||||
Y | Coefficient for Materials. | ||||
d | Inside Diameter of Pipe, mm. | ||||
A | sum of mechanical, corrosion, erosion allowance,mm. |
Reinforcement of welded branch connections
Formula used are:
- d1 = [Dob - 2(Tb - A)]/sin α
- d2= greater of d1 or (Tb - A) + (Th - A) + d1/2
- L4 = lesser of 2.5(Th - A), mm or 2.5(Tb - A) + tr, mm.
h | subscript referring to run or header. | |||||
b | subscript referring to branch. | |||||
|
nominal thickness of run or header. | |||||
|
nominal thickness of branch. | |||||
d1 | effective length removed from pipe at branch, mm. | |||||
d2 | "half width" of reinforcement zone, mm. | |||||
L4 | height of reinforcement zone outside of run pipe, mm. | |||||
Tb | branch pipe thickness, mm. | |||||
Th | run pipe thickness, mm. | |||||
tr | minimum thickness of reinforcing pad, mm. | |||||
tmh | pressure design thickness of run pipe, mm. | |||||
tmb | pressure design thickness of branch pipe, mm. | |||||
α | smaller angle between axis of branch and run. | |||||
Dob | outside diameter of branch pipe, mm. | |||||
Doh | outside diameter of run pipe, mm. |
- A7 = (tmh - A)d1(2 - sinα), mm2
- A1 + A2 + A3 + A4 + A5 >= A7
where:
A1 | Area resulting from excess thickness in the run pipe wall, mm2. | ||||||||
A2 | Area resulting from excess thickness in the branch pipe wall, mm2. | ||||||||
A3 | Area provided by deposited weld metal beyond the outside diameter of the run & branch, mm2. | ||||||||
A4 | Area provided by a reinforcing ring, pad or integral reinforcement, mm2. | ||||||||
A5 | Area provided by a saddle on right angle connection, mm2. | ||||||||
Dr | Outside diameter of reinforcement ring, mm. | ||||||||
Sr | Stress value for reinforcement ring material, N/mm2. | ||||||||
ha | Height of the fillet weld between run pipe & reinforcement ring, mm. | ||||||||
hb | Height of the fillet weld between branch pipe & reinforcement ring,
mm. |
