For pipe weld integrity

Advances in weld technology and techniques require equally advanced testing capabilities. Understanding the need to ensure weld integrity in oil and gas pipelines, Exova has developed one of the leading capabilities in Immersion Ultrasonic Testing (IUT). This enhanced version of Automated Ultrasonic Testing (AUT) improves accurate sizing and reduces the risk of missing defects in girth welds. Our capabilities will help you secure project quality and the assurance that pipelines are free from critical defects.

The devil is in the detail

Immersion Ultrasonic Testing is particularly relevant for discovering smaller defects, which helps improve Probability of Detection (POD). It also increases the number of indications that can be identified. From cracking to porosity, incomplete penetration and lack of sidewall fusion, each can compromise pipeline girth weld strength at critical parts within the weld. The process can also support a broad range of requirements as it can be applied to any kind of girth weld up to 48”, any wall thickness, as well as any material.

Innovative solutions for girth weld testing

Fusion flaws in narrow gap and shallow angle groove welds are difficult to detect with traditional radiographic testing methods. Automated Ultrasonic Testing was developed to address this, but accurately determining the size and location of these flaws has remained a challenge.

Exova has developed Immersion Ultrasonic Testing techniques that not only identify an increased number of defects, they increase the Probability of Detection and reduce both the risks associated with undersizing a flaw and the costs of needlessly fixing flaws which have been oversized.

Exova’s Immersion Ultrasonic Testing capabilities can help you identify:

  • Cracking
  • Inclusions
  • Incomplete penetration
  • Lack of sidewall fusion
  • Porosity
  • Other weld strength defects

Automated Ultrasonic Testing

A calibration process has also been to construct signal characteristics and thresholds closely mirroring those in the Automated Ultrasonic Testing system to ensure as near possible like for like examination conditions.

Exova’s new Immersion Ultrasonic Testing technique satisfies the functionality required for the Automated Ultrasonic Testing validation procedure for girth weld inspection.

Software solutions

Our team is constantly seeking to develop new technologies and software functionalities to further support the oil and gas industry.

The Immersion Ultrasonic Testing service provides exportable raw data (A-scans) which is supplied to the customer together with viewer software to review and analyse test results.
