3.4.1. Determination of testing pressure:
Hydraulic testing pressure of boilers after being installed according to the following table:
Design pressure,MPa
p ≤ 0,5
p ≥ 0,5
Hydraulic testing pressure,MPa
2 p but not less than 0,2 MPa
1,5 p but not less than 1 MPa
Hydraulic testing pressure of boilers when testing regularly or irregularly depends on the permitted standard working pressure according to the following table:
