BEND TO ENSURE THE QUALITY OF THE PIPES CONNECTION

IMPORTANCE OF FLANGING TEST

Flanging Test is a test method for determining the ability of metallic tubes of circular cross-section to undergo plastic deformation during flange formation. The flanging test to ISO 8494 and ASTM A370 is a test method in which the end of a tube is bent by 90°. The flanging test is normally performed on tubes having an outside diameter of 150 mm and a wall thickness no greater than 10 mm.

WHY IS THE FLANGING TEST IMPORTANT FOR PIPE WELDING?

Like flaring tests, a flanging test is carried out by expanding a pipe section using an angled conical mandrel. However, in this test, the end of the pipe is formed until an angle of 90° is achieved, simulating a flange. Additionally, the flanging test shall be performed until the inner or outer diameter of the pipe is expanded as per relevant product specifications.

Traditionally, the method used to prove the integrity of a weld would involve flooding the pipeline to hydro test. This proves to be time-consuming and costly. The test determines, through plastic deformation, whether tubes are suitable for flange formation.

Our expert testing team will apply flange weld testers for hydrostatic testing of the integrity and tightness of new and / or old welds.

Benefit of flanging test

Timely completion of maintenance and modification activities

No requirement to flood and de-water gas systems

No need for full system pressurisation beneficial to 'mature' systems by decreasing the potential for spading / leakage

Timely completion of maintenance and modification activities

No requirement to flood and de-water gas systems
