We provide the most in NDT inspection
Nous allons aussi loin que cela est necessaire pour donner le meilleur
« All our technicians are trained according to the ASNT standards, and SAQCC COTEND »
We provide the most comprehensive technical methods available. Our inspectors are multi skilled and are certified to ASNT according to SNT-TC-1A and COTEND according to EN 473 and ISO 9712 in different NDT methods such as MT, PT, VT, UT, RT and ET. As a corporate partner of the American Society for Non Destructive Testing (ASNT) we follow strict guidance to code of practice with full commitment to revising our operating procedures to suit changes in NDT Standards. We regularly recalibrate our measuring and monitoring equipment as detailed in our technical document to meet industry best practice and to further ensure reliable results while conducting inspection on any equipment under examination.
This NDT method is accomplished by inducing a magnetic field in a ferromagnetic material and then dusting the surface with iron particles. Surface and near surface flaws produce magnetic poles or distort the magnetic field in such a way that the iron particles are attracted and concentrated.
This is a method that can be employed for the detection of surface-breaking defects in anyindustrial product made from a non-porous material. This method is widely used for testing ofnon-magnetic materials. In this method, a liquid penetrant is applied to the surface of theproduct for a certain predetermined time, after which the excess penetrant is removed fromthe surface. The surface is then dried and a developer is applied to it. The penetrant whichremains in the defect is absorbed by the developer to indicate the presence as well as thelocation, size and nature of the defect.
Visual Testing is a common method of quality control, data acquisition, and data analysis. Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non specialized inspection equipment.
In ultrasonic testing, high-frequency sound waves, created by a crystal in probe, transmitted into a material to detect imperfecor to locate changes in material properties.
Using a wall thickness gauge, we can easily measure the thickness of non-corroded metal. It is particularly practical when the back of the material is not available, which is the case with many hulls of boats and metal pipes.
The radiographic testing method is used for the detection of internal flaws in many different materials and configurations. An appropriate radiographic film is placed behind the test object and is exposed by passing X rays or gamma rays (Co-60 & Ir-192 radioisotopes) through it. The intensity of the rays while passing through the object is modified according to its internal structure and thus the exposed film, after processing, reveals a shadow picture known as a radiograph. It is then interpreted to obtain data about the present defects.
This method is widely used to detect surface defects, to sort materials, to measure thin walls from one surface only, to measure thin coatings and in some applications to measure case hardening depth. This method is applicable to electrically conductive materials only. In the method, eddy currents are induced in the object by bringing it close to an alternating current carrying coil. The alternating magnetic field of the coil is modified by the magnetic fields of the eddy currents. This modification, which depends on the condition of the object near to the coil, is then shown as a meter reading or cathode ray oscilloscope presentation.
