NON DESTRUCTIVE TESTS

The non-destructive tests (NDT) allow you to identify any defects present in a component without altering its structural integrity or modifying its properties. The techniques used are generically divided into superficial and volumetric. Sider Test is able to perform non-destructive tests according to the methods listed below, both at its own facilities and at client companies or places (construction sites or plants) where the components to be checked are installed. In addition to these techniques, there are also other types of non-destructive tests, such as the execution of metallographic replicas , the application of strain gauges and the detection of hardnesses using portable hardness testers.

For all the methods listed below, Sider Test has level II and III personnel qualified in accordance with ISO 9712 and SNT-TC-1A .

Ultrasonic-examination

ULTRASONIC EXAMINATION

Non-destructive method that is based on the propagation of ultrasonic waves in the object to be examined and on the analysis and interpretation of the transmitted signals, reflected or refracted by any defects

Radiography

RADIOGRAPHY

Volumetric control to highlight defects such as internal discontinuities, voids, blowholes or lack of penetration of the weld. On request also on worksite near the customer

magnetic-particles

MAGNETIC PARTICLES

Magnetoscopy to locate any surface or sub-surface defects (applicable only for ferromagnetic materials). Non-destructive method performed by qualified personnel also at the customer’s facilities

Penetrant-test

PENETRANT TEST

To identify any surface defects, such as discontinuities, cracks and failed fusions. The test involves the application of liquids and detectors that make the discontinuities visible

Visual-examination

VISUAL EXAMINATION

Conducted by highly qualified personnel to verify the surface quality of the components and to identify defects and non-conformities. With the naked eye or through endoscopes or micro cameras
