Overtime, internal surface of steel pipelines are subject to the formation and buildup of aggressive corrosive deposits.  These deposits attack and destroy pipe steel and create surface friction that reduces throughput.

Internal coating services from RPS are proven to stop corrosion, increase throughput, extend pipeline life, and reduce maintenance and inhibitor costs all at a fraction of the cost of pipeline replacement.

ADVANTAGES OF OUR INSITU INTERNAL PIPELINE COATING PROCESS:

✔️ PREVENTS INTERNAL PIPELINE CORROSION

The RPS Insitu Coating process is guaranteed to stop internal pipeline corrosion.  It can be used to rehabilitate older pipelines or on new pipelines that are in corrosive service.  The multi-layered epoxy coating prevents the attachment of corrosive elements to the steel surface.

✔️ EXTENDS PIPELINE LIFE FOR A FRACTION OF REPLACEMENT COST

Insitu epoxy coating of an existing pipeline will stop future internal corrosion extending the life of the pipeline for many years, typically, at a fraction of the cost to replace the pipeline.  Reduction in inhibitor costs and maintenance costs, and increased throughput and energy savings offer additional benefits.

✔️ Preforms ON LONG PIPELINE SECTIONS

Performed in-place, segment lengths as long as 20 Kms can be cleaned and coated at a time. Access only to the ends of the pipeline segment is required.     

✔️ PROVIDES HOMOGENEOUS COATING

Insitu coating provides a uniform homogeneous coating throughout the pipeline including al field joints (welds) and bends. No other commercially proven process can make that claim.

RPS' INFIELD INTERNAL COATING PROCESS CONSISTS OF THE FOLLOWING STEPS:

  • Mechanical Cleaning

  • Chemical (HCL) Cleaning Surface Preparation

  • Surface Cleanliness Inspection

  • Passivation & Drying

  • Coating Application

  • Coating Thickness and Adhesion Testing

Suitable for CO₂ Pipelines

Internal pipeline corrosion due to carbon dioxide is a major challenge facing the oil and gas industry. Transmission of CO₂ gas can be highly corrosive for a pipeline, impeding its safe transport and storage. Our coating partner, Akzo Nobel can evaluate your process and select an appropriate coating suitable for the RPS insitu application.

Our proven epoxy coating system, backed by our supplier’s CO₂-resistant formulation, creates a robust barrier against corrosion and degradation—extending pipeline life and reducing the cost and complexity of CO₂ transport infrastructure. Whether you're preparing for CCS (Carbon Capture & Storage) projects or expanding into CO₂ EOR (Enhanced Oil Recovery), we provide a fast, cost-effective retrofit solution that meets today's operational and environmental demands.
