I have to go to site to rectify the support system. Support design has been done considering the rigid couplings and now there is leakage of water during hydrotest.
The pipe is running in rectangular path inside the building (50mx30m)
My solution and understanding so far is like this -
1. I will provide rest+guide at both the ends of all the couplings to rigidify the system.
2. After providing this kind of supports if pipe expands due to pressure then the solution which i considered was to provide anchor at every change of direction but then the load coming is very high (120KN) and this pipe is GI so I cannot do any welding on pipe and now I am stuck what to do??
