Internal and External Pipe Lining in Ohio
Before diving into why RAK is the top choice for internal and external pipe lining and coating, it’s important to first understand the distinction between the two. External pipe coating is used to protect the metal of a pipe from a corrosive environment. Internal pipe lining protects the pipe from corrosive fluids. There are certain instances when both are needed, and there are certain times when only one is needed.
At RAK, we can assess your particular situation and determine what coating and/or linings are right for your pipes.
External Pipe Coating
Pipes can be coated externally to protect them from corrosion, erosion, and mechanical stress. Coating a pipe externally involves the application of metallic, or non-metallic, materials on the external service of the pipe, which is either seamless or welded.
The most common materials to coat pipes externally with are:
- Non-metallic pipe coatings such as paints, varnishes, lacquers, bituminous coatings, resins, plastics, and so on.
- Organometallic pipe coating such as paints pigmented with metals
- Chemical modification such as phosphating or chromatin
- Physicochemical modification
Internal Pipe Lining
Internally lined pipes are fitted with an internal protective material that is mechanically inserted into the tubular section.
The most common materials to line pipes internally with are:
- Teflon (PTFE)
- Cement mortar
- Liquid epoxy
- Fusion bonded epoxy
- Bituminous asphalt
At RAK, we will help you find the right external coating or interior lining for your pipe systems. We’ll match the environment and materials present in and around your pipes with the right material that will be corrosion resistant and stand the test of time.
