My engineering department are raising concerns that a Copper Nickel pipe system utilizing 16bar rated pipe, and ANSI 150# flanges will not be able to withstand a 25 bar surge pressure. Are they right to be worried or are they being overly cautious ?
How practical is it to glass flake epoxy coat small bore (4"nb) pipe work ? I have a fire fighting skid which i propose to FBE coat the pipework but the client seems insistent on glass flake. any advise much appreciated.
Can someone confirm or correct my understanding of the terms firetested and firesafe;
A firetested valve must be operable after the test but need not be seal tight whereas a firesafe valve must fully seal.
The reason for my question is a client is requesting a rubber lined firesafe butterfly...
i often see valves specified with 16 bar max working pressure and 24 bar design pressure.
Max working pressure is self explanatory but what exactly is meant by design pressure
im designing a mechanical skid package (pipework, valves, storage tank)with pressure and level transmitters included. The skid is located in a safe area. Why would the clients consultant want instruments certified as suitable for Zone 2 IIB T3 ?
Any problems/issues with clamping a lugged pattern b'fly valve between a flat face GRP flange on one side and a composite weld neck flange in CuNi on the other ?
i am trying to connect a fire fighting skid with all CuNi pipework to a GRP fire main. My contract terminates at the valve face but i...
Does anyone know of a fabrication 'norm' for steelwork fabrication estimating. I use JS Page Pipe manhours for my pipe fabrications but cannot find anything similar for steel fabs
I have a client spec asking for an atmospheric storage tank to be designed to ASME VIII div 1.
I understand this code is for pressure vessels not atmospheric tanks - any advise please ?
