1. Measure the DACHENG PIPE PLUG diameter and length in meter.
2. Confirm PIPE PLUG inflation pressure in pa.
3. Confirm friction coefficient between the plug and pipe.
4. Confirm density ofm.
5. Confirm gravity acceleration of the medium.
The following is the calculation formula:
Working pressure=(D*L*inflation pressure*friction coefficient)/(density*gravity acceleration*r*r)
For Example :
DN380600 PLUG application for 500mm concrete pipe.
Plug Diameter : 0.38m
Plug Length ：0.8m
Inflatable Pressure : 55000pa
Friction coefficient : 0.5
Density : 1000kg/m3
Gravity Acceleration:9.8N/KG
Working pressure=(0.38*0.8*55000*0.5)/(1000*9.8*0.19*0.19)=23.6M
