Plastic Pipe in Industry

PLASTIC pipe is finding increasing acceptance in industry, especially in transporting corrosive materials. Depending on the substances involved in its manufacture, plastic pipe has high tensile strength and in some cases, it is said, better weight‐strength ratio than either steel or aluminium and higher impact resistance than many metals. Its chemical resistivity makes it suitable for sewage and chemical disposal lines, electrical conduit and some petroleum applications. It can be coupled to standard metal piping with plastic or metal fittings and generally is readily machined and threaded by slightly modified dies. Some types of material used are self‐extinguishing and provide good insulation against heat and electricity. The use of plastic pipe is not only economical and practical for many applications, but it reduces maintenance requirements and replacements because of its long‐lasting quality.
