2. Differences between an ERW and spiral welded pipe tester

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.

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.
