I am trying to determine the relief load required for overpressure protection of a natural gas system.
The system I am analyzing takes pipeline natural gas (800 psig), and uses a pressure reducing valve to lower the pressure to the equipment (400 psig). There is a safety valve on the downstream...
Hi,
I am working on a piping modification project that involves hot corrosive fluids (>200000 ppm chlorides, 200 F). The current piping is 1.5" sch 10, and the material is 6% moly (254SMO). Design pressure is 15 psig.
As part of the project, we will need to tie in new piping to the old...
Hi All,
I am trying to put together project documents for the control valves on a process piping project. The design will be issued to a number of contractors to bid on. I am trying to understand where the design responsibility is split between engineer and contractor for control valves, and...
Hi All,
I wanted to see what others were using to do construction cost estimating for industrial jobs.
We are a smaller EPC firm who usually hires an estimator to help bid jobs but we want to start taking this on ourself.
I'm looking for techniques, methods, or software to start to learn this...
Hi All,
I am working on foundation design for a Battery Storage enclosure and had some concerns. The design will go to a senior for review but for my own development I'm trying to take it to completion.
Background
The battery enclosure is a modified and braced shipping container, designed by...
Hi all,
I am a part of a project that involves adding a new mat foundation for a new skid (the foundation will only be about 12" deep). The location of the foundation is currently being decided, but we know it will be near an existing foundation.
At what point does an engineer decide to tie-in...
Hi all,
A project is coming up that involves moving a berm (roughly 5ft tall by 6ft wide, maybe 30 feet long). The project is mainly electrical but I understand that some civil will be involved because of this.
What sorts of civil studies/calculations should I expect to come from this task...
