Design Pressure and Flow for thrust block design
Design Pressure and Flow for thrust block design
(OP)
Hi there,
I'm busy with the thrust block design for a bulk gravity waterline.
Do I use the operational (dynamic) pressure and flow as input for the calculation of resultant forces, or do I use the maximum pressures during surge conditions obtained from the surge analysis?
Any logic explanation would be appreciated.

RE: Design Pressure and Flow for thrust block design
The test pressure is generally 50% higher than the operating pressure.
The pipeline designer should attempt to minimize the maximum pressures from surge conditions through design.
The pipeline designer must decide if the maximum operating pressure, the line test pressure, or the maximum anticipated surge pressure should be used in calculating thrust restraint. Obviously, the higher the pressure, the more restraint required.
