Real-time digital radiography ensures quality on a 400+ km gas pipeline in Mexico

The scope of work focuses on the technical evaluation of circumferential welds, which connect each section of the pipeline and represent critical points where defects could compromise the integrity of the system if they fail to meet the required standards. To address this, Applus+ is implementing a specialized non-destructive testing (NDT) program using advanced Rayscan real-time digital radiography (RTR) technology.

This technology enables inspections to be performed directly in the field, even under demanding conditions such as trench operations, providing immediate detection of internal discontinuities including porosity, cracks, lack of fusion, and other welding defects. This approach not only verifies the quality of every weld but also ensures compliance with international codes and standards before the pipeline is commissioned.

From a technical perspective, the project combines Applus+ expertise in industrial inspection, asset integrity, and quality assurance for oil and gas projects, delivering real-time results, fully digital inspection records, and complete data traceability. This integration of advanced technology and technical expertise supports faster decision-making on site, optimizes construction schedules, and minimizes the need for costly rework.

One of the key project risks is the possibility of weld defects that could compromise pipeline tightness, operational safety, or regulatory compliance, potentially resulting in economic, environmental, and reputational impacts. Applus+ helps mitigate these risks through continuous inspection, rigorous technical quality control, and the generation of verifiable inspection records, ensuring that every pipeline component meets the specified acceptance criteria.

The project also incorporates strict safety protocols, particularly in the management of ionizing radiation. Certified personnel, continuous monitoring, and compliance with international radiation protection standards ensure that inspection activities are carried out safely without compromising operational efficiency.

As a result, the service helps ensure the mechanical and operational integrity of the pipeline, reduces construction deviations, minimizes costs associated with late-stage corrective work, and provides the client with reliable, auditable information to support long-term asset management.

Through projects such as this, Applus+ continues to strengthen its position as a trusted technical partner in non-destructive testing, advanced inspection, and asset integrity assurance for hydrocarbon transportation infrastructure, delivering value throughout the entire asset lifecycle while contributing to safer, more efficient, and more sustainable operations across the energy industry.
