Main Objective
Onshore gas and liquid transmission pipelines play a critical role in delivering the energy resources needed to power communities for the national economy and society need, while effective protective coatings (along with cathodic protection), in terms of high resistance to corrosion, allow smoother operation and higher level of public safety. Much research on the fundamentals of corrosion of pipelines has been extensively studied and various methods have been used for corrosion control. However, PHMSA data revealed that corrosion is still one of the leading causes of failures of metallic pipelines in the United States and worldwide. Protective coatings on pipelines, as one of major corrosion control strategies, must be designed with sufficient resistance to corrosion. In most cases, a sound anti-corrosion coating design can be carried out to achieve this one specified performance level. However, considering that corrosion, fouling and wear problems are still of great relevance and interrelation in a wide range of corrosion-induced pipeline failures, either of them could trigger/accelerate others, thereby potentially speeding up the degradation and causing eventual failure in a short life. In a harsh conditions pipelines experience and particularly to extend the service life, it is often required that a protective coating achieves multiple performance/functional levels under corrosion, fouling and wear events. As emerging technology, high performance anti-corrosion coatings have recently demonstrated great potential and attracted significant interest for oil and gas pipeline corrosion control. Towards this endeavors, the combined efforts in new high-performance coating design with superior resistance to corrosion, fouling and wear must be made for enhanced prevention and mitigation of pipeline corrosion. The final deliverables of the proposed work are to develop and implement new multifunctional composite coatings for new-constructed or existing pipelines to achieve an acceptable and economical design with multiple performance/functionality levels. The integration of the anti-corrosion, anti-fouling and superior abrasion into one compact unit (composite coating) will make the acceptable/optimal solution cost effective as well. The specific aims of the work are: a) to develop a comprehensive and systematic study for formulation and characterization of the new high-performance coatings, b) to characterize the chemical activities at interfacial behaviors (bond and long-term durability) among coating layer and steel substrate, and experimentally validate the effectiveness of the new coatings in terms of anti-corrosion, anti-fouling and abrasive resistance using accelerated durability tests, and c) to characterize the performance of the new composite coatings in field
Public Abstract
Corrosion is one of the leading causes of failures of metallic pipelines in the United States and worldwide. Severe corrosion-induced pipeline accidents in recent years have raised more widespread attention to safety issue that brings high risk to people's life, and surrounding environments. This study aims to develop and implement new high-performance multifunctional composite coatings, striving for lifetime preventing and mitigating internal pipeline corrosion for onshore gas and liquid transmission pipelines. By taking advantage of the unique properties of high performance polymer primers and nanoparticles and nanofibers as additives, the new functionalized high-performance composite coatings will significantly reduce interrelated corrosion-fouling-wear issues, effectively elongate the performance life of metallic pipelines and ultimately protect them under severe corrosive environments. The new multifunctional composite coating will be highly paid off for next-generation pipelines lifetime protection in terms of superior ant-fouling resistance and abrasive resistance, and long- lasting corrosion resistance, thereby introducing tremendous economic benefits. The development and utilization of the coating technologies can dramatically enhance operational safety in metallic pipelines in terms of reduction of coating maintenance and repaint costs, as well as corrosion- related accidents, injuries, fire and delays, and will have a significant impact on U.S. PHMSA operations, support and implement corrosion control practices and will ultimately improve the quality and thus structural safety of constructed pipe structures.
Summary and Conclusions
This project provided a comprehensive investigation of the new high-performance coatings, from fabrication, characterization, to overall performance, striving for superior protective coatings for internal corrosion mitigation of oil/gas pipelines. The project proofs the proposed concept, and fulfills the targeted outcomes:
- Excellent corrosion resistance
- Significant improvement on mechanical properties
- High anti-fouling capacity
- The results obtained during the accelerated corrosion test revealed the proposed coating was durable, as its excellent corrosion resistance and superamphiphobicity remained undamaged after exposure.
