What if... we can prevent degradation?

What is NDT?

NDT stands for non-destructive testing, which does not damage the object to be inspected. This inspection method assesses the usability and physical condition of assets without affecting them.

NDT is applied to assess the condition of objects. Within Intures we focus on concrete and steel structures in industry and the civil market, and we check for degradation.

The NDT methods in which we have a great deal of expertise include visual inspections, penetrating crack examination and ultrasonic examination. Intures can apply other forms of NDT in collaboration with third parties.

Visual inspection

One form of NDT that we perform as a baseline measurement is a visual examination. The method is based on the human sense, with or without the support of non-specialized equipment.

Visual inspections are often performed using checklists to ensure completeness. These checklists are based on predetermined criteria and/or standards.

Penetrant examination

Penetrant examination is an NDT method that is often used to map (possible) cracks. This research is mainly carried out on non-iron alloys.

By allowing penetrant liquid to penetrate into openings on the surface of the object to be inspected and then removing the penetrant with a layer of developer, a color contrast is created. The resulting colored spots indicate the position and shape of the cracks.

Ultrasonic examination

An NDT method in which inspection is carried out based on inaudible sound is ultrasonic examination. This allows all kinds of abnormalities to be detected on the inside of an object. This method is often used to map the residual wall thickness as part of research into the residual lifespan.

Using a probe, a device that generates sound waves, ultrasonic sound is emitted through the object to be inspected. At a defect or an edge of an object where there is an abnormality, the sound waves are reflected and detected by the probe. The probe then converts these waves into an electrical signal. We mainly carry out these studies on steel structures.

Why NDT?

NDT is required when an objective assessment of the condition of the material must be obtained without damaging the object. Specialist NDT methods are used to enhance visual inspections, for example to look deeper into the material. These objective observations can be used as part of studies into the residual life of assets.

Why NDT at Intures?

Intures distinguishes itself because we carry out the entire inspection process from A to Z ourselves. If necessary, we seek collaboration with third parties to ensure that we can deliver the highest quality.

NDT is only part of what we can offer. We relieve our customers as much of their worries as possible: including all preparation of inspections, drawing up work plans, analyzing measurement results and providing advice. We assess any identified defects for possible risks relating to integrity and safety.

Thanks to our service package, we can also offer our clients support after the inspection phase. If requested, Intures can further develop findings into a multi-year asset management strategy. Also we can provide support in planning and carrying out management and maintenance activities, including engineering and implementation guidance.
