PLASTICS or METAL? Reprinted from CHEM! Materials, Processing & Control By George Black, Communications Consultant During the first half of the last century the decision concerning which material to use for a fluid handling application was relatively simple. Choices were limited to determining which metal would prove most cost effective for the service conditions. Corrosion
Chemical plants and municipalities rely on thermoplastic pumps for odor control, corrosion resistance and reduced maintenance. A recent study conducted by Pollution Engineering revealed that approximately 40% of the respondents use nonmetallic pumps at their facilities… even more significant, approximately 30% expected the number to increase over the next three years. The primary reasons for
