Grinnell Products, a brand of Tyco International, announced the release of its G-Mine PVC piping system, comprising high-strength PVC (polyvinyl chloride) pipes, couplings and fittings—all of which conform to ASTM D 1784 and are extremely resistant to harsh environments, acids, and most chemicals. According to the company, the pipe and fittings are manufactured from a specially formulated PVC compound that provides higher impact strength over an extended period of time, allowing installation in above-ground, exposed applications. The system features piping and non-corrosive restrained joints that use precision-machined grooves on the pipe and in the fittings; when aligned, these grooves allow easy insertion of a spline, which locks the pipe and fittings together. A flexible, elastomeric seal (O-ring) in the fitting creates a hydraulic seal.
