1. Brief Introduction
A hydraulic tester is used to perform leaking and hydraulic
pressure test on ERW or spiral welded pipes. The test involves
sealing the two ends of the pipe, and filling the pipe with a
liquid, usually water, which may be dyed to aid in visual leak
detection, and pressurization of the vessel to the specified test
pressure. Pressure tightness can be tested by shutting off the
supply valve and observing whether there is a pressure loss.
Tengtian hydraulic tester reaches API standard.
2. Differences between an ERW and spiral welded pipe tester
Longitudinal weld pipe hydraulic tester employs outside diameter’s
sealing or sealing for big gaps; hydraulic tester for spiral
welding pipes uses polyurethane to seal the pi[e end faces, and has
the system to keep balance of oil and water.
3. Process flow
Pipe installation – Sealing – water filling – pressurization –
pressure relief – drainage – pipe uninstallation
