what is piping?

Corrosion, leaks, and aging pipes are major threats to industrial operations. Epoxy piping has emerged as a powerful solution—restoring and protecting pipelines while minimizing downtime and cost. But what exactly is epoxy piping, how does it work, and is it the right choice for your facility? This guide from RAK Industrial Services delivers the facts you need to make an informed, confident decision.

What Is Epoxy Piping?
Epoxy piping is a pipe rehabilitation method where a high-performance epoxy resin is applied to the inside (and sometimes outside) of existing pipes. The epoxy starts as a liquid, coating the pipe interior before curing into a seamless, tough, and chemical-resistant lining. This process restores pipe integrity, blocks future corrosion, and stops leaks—all without the need for full pipe replacement.

How Does Epoxy Piping Work?

• Inspection & Assessment:
  Using advanced cameras or sensors, technicians evaluate the pipeline’s internal condition—identifying corrosion, blockages, or leaks.

• Surface Preparation:
  The interior is cleaned, usually via abrasive blasting or air scouring, to remove buildup and ensure the epoxy will bond effectively.

• Epoxy Application:
  The resin is applied by inversion, spray, or brush, thoroughly coating every surface.

• Curing:
  The epoxy hardens into a continuous, impermeable lining that returns the pipe to peak performance.

• Final Inspection:
  Inspections verify that the lining is uniform, at the right thickness, and free of defects—ensuring long-term results.

Benefits of Epoxy Piping

• Creates a seamless, corrosion- and leak-resistant barrier inside the pipe
• Trenchless application means minimal excavation or disruption to operations
• Extends the life of existing pipelines, often by decades
• Improves flow due to a smooth, non-porous interior lining
• Many systems are NSF 61 certified for potable water and food-grade use
• Fast project turnaround—ideal for facilities where downtime is not an option

Limitations of Epoxy Piping

• Not a structural reinforcement—pipes with severe wall loss or collapse may need carbon fiber, FRP, or replacement
• Requires expert surface preparation to ensure proper adhesion and durability
• Best suited for certain diameters and pipe geometries; extreme conditions may require specialty linings (vinyl ester, plural-component, etc.)
• High-temperature or aggressive chemical applications may call for alternative materials

Is Epoxy Piping Right for Your Facility?

Epoxy lining is an excellent fit for water, wastewater, compressed air, and many chemical process lines—especially when you need to extend asset life, control costs, and avoid shutdowns.

RAK Industrial Services always starts with a professional assessment—considering pipe materials, internal conditions, service environment, and operational needs. If epoxy isn’t the optimal solution, our experts recommend and install advanced alternatives to ensure true, maintenance-free performance.

Epoxy piping is a proven, cost-effective way to restore and protect pipelines—without the disruption or expense of full replacement. For industrial operators who need reliable, long-term results, RAK Industrial Services delivers expert application, advanced materials, and total peace of mind.
