Failure Analysis & Material Evaluation Of Pipelines

Owners manage the integrity of above-ground and buried pipelines with numerous systems and processes. However, there can be unforeseeable circumstances or system breakdowns which precipitate failures of piping and auxiliary equipment. Acuren’s highly experienced engineers can perform failure analysis, evaluate material properties, suggest alternatives to materials, testing/monitoring procedures to help Owners prevent future occurrences. As part of the failure investigation / product evaluation, engineers assess the components in the field and/or laboratory which may include:

• Detailed analysis of pipeline fracture surface to determine failure mode/mechanism
• Determine if pipe meets the specified mechanical and chemical properties with laboratory testing
• Optical microscopy and scanning electron microscopy to evaluate material microstructure, flaws and fracture surfaces
• Determine presence of bacteria involved in microbiologically influenced corrosion (MIC)
• Identify type of corrosion scales and foreign debris using x-ray diffraction (XRD) or energy dispersive x-ray (EDX) spectroscopy
• Perform burst testing of pipe to predict failure pressures, strain and fracture mode
• Crack Tip Opening Displacement (CTOD) testing to determine critical allowable flaw sizes in pipe welds
• Provide independent failure analysis and reports for regulatory bodies

Committed To Excellence

Committed to delivering a higher level of reliability, Acuren provides an unrivaled spectrum of services to support the safe operation of industrial assets. Acuren’s commitment to safety, quality and professionalism spans four decades. We have programs to manage risk in all environments as well as robust programs to manage resources, equipment, personnel, environmental practice, audit, reporting, safety and customer stewardship expectations. Our expertise in weld inspection, crack sizing, corrosion mechanisms, and deformation has made us the first call for natural gas and liquid pipeline operators across all climates.

Our goal is to provide pipeline integrity programs, services and threat management programs to meet the increasing demands of our pipeline customers. Acuren has dedicated years of training and resources to ensuring the value we deliver through our pipeline integrity programs far exceeds that of our competition.

Execution Excellence: dedicated pipeline integrity operation ensuring safety, quality and scope execution excellence Specialization: technicians specifically trained and dedicated to supporting pipeline integrity programs rather than general NDE technicians Damage Mechanism Capabilities: technicians have specific and intimate damage mechanism identification capabilities Scalability: we have a pipeline integrity technician pool that spans North America Multiple Disciplines: our pipeline integrity technicians have experience in multiple disciplines: coatings, cathodic protection, soils geology, inline inspection and NDE Program Management: verification of log data, interpretation of inspection results and threat management
