XCorr® Provides Mechanical Reinforcement for Pipeline Repair in Brazil

by InduMar Products, Inc.

A recent repair in Brazil outlines the strategic repair approach taken on a compromised pipeline. Following an inspection that identified multiple localized defects, a targeted repair process was implemented under challenging operational conditions. The project focused on restoring pipeline integrity using an advanced multi-layer repair system, while navigating operational constraints such as limited repair capacity and demanding environmental factors. Detailed aspects of the inspection findings, repair methodology, and operational parameters are discussed in subsequent sections.

Problems

  1. Internal Corrosion: Significant internal corrosion was detected, having caused to up to 40% wall loss in critical areas.
  2. Structural Degradation: The UT inspection revealed 28 spot defects, indicating widespread structural degradation that required immediate attention to prevent potential leaks or failures.
  3. Operational Stress: The pipeline’s high operating pressure (950 psi) and elevated temperature (125°F) exacerbated material stress, necessitating robust repair solutions to maintain safe operations.
  4. Limited Repair Window: With repairs constrained to one per day by a four-person technical crew, the process demanded precise planning and execution to minimize downtime while ensuring the quality and reliability of each repair.

Project Needs

  • Structural integrity: The pipeline exhibited significant wall loss due to internal corrosion, reducing its strength and pressure rating. A repair strategy was essential to addressing the degradation to ensure continued safe operations.
  • Mechanical reinforcement: A tailored composite wrap solution was important to restore the pipelines mechanical strength and operating capacity. The reinforcement required precise engineering to counteract the effects of corrosion and degradation.
  • Compliance: The repair process was required to meet ASME PCC-2 guidelines. This involved implementing robust mechanical testing protocols to verify that the restored pipeline adhered to industrial safety and performance standards.

Product: XCorr® 100
Composition: Two-part Novolac epoxy with fiberglass reinforcement.
Surface Preparation: SSPC-SP6
Working Time: 20-30 minutes, temperature-dependent.
Cure Time: 24 hours, temperature-dependent.

Provided Protection

  • Mechanical Reinforcement: XCorr® 100 was selected to restore wall loss and build back hoop strength that was lost due to corrosion.
  • Durability and Reliability: Engineered for high tensile strength, the durable repair solution offered long-term performance based on extensive testing.
  • Compliance: The XCorr® 100 repair complies with ASME PCC-2 guidelines as required by asset owners.
  • Tested Performance: XCorr® capabilities have been validated through rigorous testing including spool survival and burst tests to confidently confirm its effectiveness and reliability in high-pressure applications.

This case study highlights the XCorr® system’s ability to provide effective mechanical reinforcement for pipelines, emphasizing its strength, reliability, and compliance with industry standards. Results of the spool survival and burst tests demonstrating the system’s ability to perform under pressure are available upon request.
