3pe anti-corrosion steel pipe testing means there is a hydraulic test, then the hydraulic test is the test of what? The following is an introduction.
 
Water pressure test is mainly used to test the 3pe anti-corrosion steel pipe pressure capacity and whether the leakage.
 
Anti-corrosion steel pipe for the reason of hydraulic test
3pe anti-corrosion steel pipe hydrostatic test should be no leakage to do each pipe hydrostatic test, according to the test pressure test pressure Mpa S - hydrostatic test, test pressure test to calculate P = 2ST / D, where the hydrostatic test in accordance with the corresponding standard provisions of the * small yield strip (Q235 is for 235Mpa), 60% of people choose.
 
Stabilization time: D < 508 test pressure time is less than 5 seconds, D ≥ 508 test pressure retention time of less than 10 seconds of steel pipe welded seam, reinforcement head and ring weld 4 nondestructive testing should be X-ray or ultrasonic inspection.
 
For ordinary combustible fluids transported to the spiral seam steel pipe should be 100% S X-ray or ultrasonic testing for water, sewage, air, steam and other general heating fluid transport pipeline spiral weld should be X-ray or ultrasonic flaw inspection (20%).
