Overview

Polyvinyl Chlorides (PVC) is one of the most widely used plastic piping materials. PVC is environmentally sound, provides long service life, is light weight and easy to install, has superior corrosion resistance, is cost effective, and widely accepted by codes. PVC pipe is manufactured by extrusion and PVC fittings are manufactured by injection molding or fabrication. PVC is an amorphous thermoplastic material with physical properties that make it suitable for a wide variety of pressure and non-pressure applications and can become pounded for optimum performance. PVC pipe and fittings are used for drain-waste-vent (DWV), sewers, water mains, water service lines, irrigation, conduit, and variousindustrial installations.Spears® high quality PVC compounds give optimum chemical and corrosion resistance with a full range of pressurehandling capabilities. Spears® PVC materials are certified by NSF International to applicable standards, including NSF®Standard 61 for use in potable water service, certified leadfree, and to ASTM STD D1784, Rigid Poly (Vinyl Chloride)(PVC) Compounds and Chlorinated Poly (Vinyl Chloride)(CPVC) Compounds that specifies Cell Classification forminimum physical property requirements. These include resin type, impact strength, tensile strength, modulus of elasticity in tension, heat deflection temperature and flammability.Spears® minimum PVC Cell Classification is 12454 for rigid(unplasticized) PVC.The ASTM Type and Grade is PVC Type I, Grade I and thetypical long and short term strength designation of materialfor pressure piping is PVC 1120.See Industry Standards and Test Methods, Physical Propertiesand Chemical Resistance sections for additional information.
