Water Based Pipe Coatings

Water based pipe coatings, are an environmentally friendly coating that is applied to the inner & outer diameter of ductile iron pipe. The water based coating serves two purposes: to protect the water supply lines from corrosion from the outside in, and also the inside out. The other primary goal of water based coating is to protect the drinking water from contamination during transfer. The coating is an emulsion manufactured using asphaltene and water primarily, with other raw materials according to the manufacturer’s specifications.

History

Water based coatings began development in the late 1980’s. In the early 90’s they began to be implemented into the ductile iron pipe industry, specifically marketed towards drinking water supply lines. Before the implementation of water based coatings, water supply lines were coated using a harmful solvent based coating. Solvent based coatings include, but are not limited to benzenes, toluenes, hexanes and other V.O.C.’s. See Volatile Organic Compound for related health risks.

Manufacturing

Water based coatings are manufactured using a batching system. A solution of raw materials and water is first manufactured. After the solution is completed, the solution is milled with an asphaltene. The asphaltene serves as a clean building block and a base resin. After the material is processed through a mill, it goes through a series of let-down, filtering, and quality control tests. What are they major uses of water based coatings The major use of water based pipe coating is for ductile iron pipe that comprises water supply lines infrastructure. It can also be utilized for the following: Pipe Flanges & Fittings

Gray Iron Pipe (Sewer Lines)

Storm water sealing

Utility Box Sealing

Septic Tank and Vault Sealing
