CORROSION CONTROL

This report which serves as a guide in selecting the right type of plastic pipe based on the material to be handled, reviews polyethylene, polypropylene, polyvinyl chloride (PVC), and polyester and epoxy (glass reinforced) pipe. The polyethylene pipes are insoluble below 50 C but as higher temperatures high- and low-density polyethylenes are soluble in hydrocarbons. These pipes are decomposed by strong oxidizing agents and slowly attacked by halogens and chlorinating agents. Moisture resistance, permeability melting point, mechanical, and physical characteristics are also outlined. Polypropylene pipe is more readily oxidized than polyethylene, the rate of attack and range of reagents increasing with temperature use, and may not be suitable for use in certain types of chemical feeding applications. The moisture effects, tensile strength and impact strength of these pipes are also discussed. The chemical stability and weatherability of PVC pipe is good but it is adversely affected by ultraviolet light. Water absorption and brittleness characteristics are discussed, as are also the tensile strength (6044.8 to 7964.9 psi for rigid PVC), compression strength (7964.8 and 9529.4 psi) and impact strength (0.8 ft-lb/in. of notch). General properties and water resistance properties of polyester and epoxy pipes are outlined, and the mechanical properties are briefly reviewed. Certain grades of epoxy fiber glass pipe have been successfully used in chemical feed lines for locomotive wash rack at pressure of 400 psi and temperature of 60 C. General comments are also made on chlorinated PVC and acrylonitrile butadiene styrene (ABS) pipes.
