Hi
We have a piping system that is buried now. These carbon steel pipes has 3inchs diameter and 3000meters length.
Can we use Dead weight tester to hydrostatic test?
These system piping must test with water at 22Bars pressure. which type of Dead weight tester we can use?
How we analyze results...
hi
I have a question about hydrostatic test of GRP PIPES, (Glass Reinforced plastic piping materials).
when PN number of a GRP pipe is (for example) 20, means maximum test pressure is 20 bars.
but these pipes test by hydrostatic test at 28 bars in the factory that is more than 20 bars. Why do...
