my design engineer insist that pumps we are going to install produce 10 bars pressure hence test pressure should be 15 bars.
my opinion is that pipe of 24 Dia, 6.4 mm wall thickness, of steel with SMYS of 30000 psi should have working pressure of 26 bars and should be tested on 39 bars
dear littleinch
our pipe line carries water pumped by turbine pumps ,standards adopted are AWWA standards, thickness of pipe wall is 6.4 mm dia of pipe is 600mm, our specification shows test pressure as 1.5 times the maximum working pressure know problem is in my opinion maximum...
i am working with client on a project of pipeline for water 20 km long. our design engineer designed the pipeline according to API 5L grade b 600 mm pipe using carbon steel of minimum yield strength of 30000 psi. i m confused as design engineer has approved 218 psi as hydro static test however...
i working on water supply project we have to construct a pond which is four meters deep two meters below ground level and two meters above NGL so we have to construct embankment two meter high which will retain 1.5 meters water soil we from excavation is of A4 category

brimmer i not the owner of project i m employee of the organization my organization hired an design engineer who has designed the project and also the specifications
thank you littleinch
problem is according to our project specification contractor has to perform ut test of 10% of joints and 100 of tie joints ,bends,golden joints and if flaw is detected he will rectify the flaw .my opinion is what will be the condition of remaining 90% if flaw rate is such...
I AM WORKING ON PIPE LINE PROJECT 600 mm dia carbon steel pipe is being but welded .my problem is that we have to carry out 10% ut of weld .results show that 6 out of 10 welds are flawed our specifications suggest repair of flawed welds.i m insisting that test must be repeated with increased...
