CHECK FOR CRACK THROUGH CRUSH DEFORMATION
IMPORTANCE OF FLARING TEST ON WELDED STEEL PIPE
Flaring Test or Drift-expanding test determining the ability of metallic tubes of circular cross-section to undergo plastic deformation in drift expansion.°.
Testing approach
The flaring test verifies the formability of tubes by expanding on a mandrel up to a determined amount without forming initial cracks. It is to test the ultimate plastic deformation ability of seamless steel pipes under the given conditions and crush deformation without crack defects.
Flaring tests are performed to determine the ductility of the test specimen as an angled conical mandrel is inserted and plunged into the pipe specimen, which causes the pipe to expand. The extent of flaring is dictated by the expansion of the inner or outer diameter of the pipe stated in relevant product specifications. Flaring Tests are also mainly performed on sections of seamless and seam-welded pipes.
Welded tube is the basic element of diverse scaffolding system. Generally, flat strip steel will be firstly formed in tubular profile and then be welded to tubes.
As a result, the weld seam is always the most weakness spot when the welded tube is used in heavy-loading construction projects.
Therefore, weld seam is require to go through flaring test, which can help us to check whether our welded tube has met above requirements or not.
