The Largest Portal of Nondestructive Testing (NDT)

Abstract: Several NDE examination methods are currently being used to inspect heat exchangers and boiler tubes. The tube material of this equipment is made from various ferromagnetic and non-ferromagnetic alloys. The tubes' sizes vary from 0.5-3.5 inches in outside diameter and from 0.028-0.120 inches in wall thickness.

Tube Inspection - Eddy Current Testing, Eddy Current NDT

Tubes may be inspected using eddy current (ECT) non destructive testing(NDT) from the outer diameter (OD), usually at the time of manufacture and from the inner diameter (ID), usually for in-service inspection, particularly for heat exchanger inspection. ID Heat Exchanger Tube Testing

Tube Inspection Technologies Old | Irisndt

Eddy Current is used to inspect non-ferrous tubes. We detect and size cracks, corrosion, erosion and mechanical damage in austenitic stainless tubes and in copper alloys. RFT is used to readily detect erosion losses in low alloy steels (ferromagnetic) and in ferritic stainless steels. Pits, corrosion and mechanical damage can be detected.

Eddy current testing strategies for copper tube

Mar 11, 2008 · Eddy current testing, a nondestructive testing technique, is suitable for such applications. Testing copper tubes is particularly important because most of them are used for air-conditioning and refrigeration (ACR) applications, heat exchangers, and so on.

Remote Field Eddy Current (RFEC) Testing Very similar to eddy current testing, this technology is specifically designed to evaluate ferrous materials. This method is well suited to conveniently evaluate the wall loss or condition of inaccessible carbon steel boiler generating bank tubes, fire tube boiler bundles, and feed water heater tubes with consistently repeatable accuracy.

Boiler steel pipe hydrostatic testing and eddy current testi

Thus, as long as eddy current testing process the right way, for the thin-walled steel pipe, it is a variety of defects can be detected in the presence of metal section thickness, it can be said that the steel pipe eddy current testing is also a dense material test, and hydrostatic testing of steel tubes equivalence.

What are the applications and capabilities of eddy currents

Tube and wire testing. Automated eddy current test systems have been developed for inspecting tube, bar and wire at speeds up to 3 m/s. Once the operator has calibrated the instrument using a tube or wire with known flaws, the test installation runs automatically, ejecting defective pieces from the production line or marking them with paint.

High pressure boiler tube hardness testing should take into account its mechanical properties, which is related to stainless steel as raw material for the deformation, such as punching, cutting processing performance and quality. Therefore, all of the high-pressure boiler tubes need to conduct mechanical tests.
