Why use Epoxy Coating Pipe? The definition of

In potable water lines, epoxy is blown into cleaned carbon steel pipes, forming a safe, evenly coated barrier between metal pipe walls and water. The epoxy lining provides a durable and long lasting solution to leaks, broken carbon steel pipe, slow drains, and blockages. The new lining increases water flow rate and water quality while it prevents carbon pipe erosion, water damage from leaks and mold

The Problem With Epoxy Pipe Lining SageWater Repipe

Dec 15, 2015 · Epoxy pipe lining is often viewed as an alternative to replacing the old piping with a completely new system. In theory, the lining process involves coating the inside of the pipes with an epoxy resin to seal off pinholes and corrosion, creating a lasting solution to solving your pipe problems. That’s the theory.

Fiberglass Reinforced Plastic Pipe

Steel pipe, on the other hand, has a Hazen-Williams roughness coefficient of 120 when new, or 65 used. The far greater loss in smoothness for the steel pipe is due to scale build-up on the steel pipe. Note that even when the fiberglass pipe is used, it is still much smoother than new steel. Fiberglass pipe is smoother than steel
