Epoxy Internal Coating Steel Pipe

epoxy internal coating steel pipe

Internal coating systems for steel pipes using epoxy-based liquid paints, including Novolac, accompanying market trends.

The principal uses of these coatings

1. To improve the flow of liquids by reducing the roughness of the pipes' inner surfaces, in the case of Flow Coating.

2. To provide anticorrosive protection, in cases in which bicomponent epoxy coatings, 100% solid epoxys and Novolac coatings are applied.

The internal surface of the pipe is cleaned previously. After cleaning, the epoxy paint is applied to the pipe's inner surface through an airless guns system, forming a uniform layer that cures in the open air.

The typical thickness for the internal coating system varies between 60 and 100μm for gas transportation pipelines and between 200 and 500μm for pipes designed to conduct water or other liquids.

Capacity

Nominal diameter: 4"~48" (Outer diameter: 114.3mm~1219.2mm)
