The elevation gradient, along with the location and volume of the water source, and the pipe design data should be used to determine the length and number of test segments. 3 2.0 purpose 4 3.0 scope 4 4.0 synopsis 4 5.0 reference documents 4 6.0 test equipment and facilities 4 7.0 calculation for hydro test 6 8.0 safety 10 9.0 selection and preparation of test section 10 8.1 selection of test section 10 8.2 preparation of the. If the stress value of the vessel material at design temprature is less than the stress value at test temprature then hydrostatic pressure should increase proportionaly.

By carrying out hydrotest at 1.5 times the mawp, we are thus taking the vessel skin to yield stress threshold. Asme b31 8 interpretations volume 15. An allowance should be made for the pipe design temperature. Rr= st/s for pipe and component without established rating but shall not exceed 6.5.
