This Heritage Plastics South Inc. PVC-400BE pipe is a 4-inch nominal diameter, 20-foot long Polyvinyl Chloride (PVC) pipe featuring a Schedule 40 wall thickness and a bell end. Schedule 40 indicates a standard wall thickness suitable for various pressure and non-pressure applications. The bell end is an enlarged, flared end designed to accept the plain (spigot) end of another pipe, facilitating solvent weld connections without requiring a separate coupling. This design reduces installation time and material costs. The pipe conforms to ASTM D1785 standards for PVC plastic pipe, which covers materials, dimensions, and pressure ratings for water, and is often dual-rated to ASTM D2665 for Drain, Waste, and Vent (DWV) systems. It is rated for a maximum working pressure of approximately 220 PSI at 73°F and a maximum temperature of 140°F (60°C). PVC pipes are resistant to corrosion, lightweight, and have smooth interior walls for efficient fluid flow, making them suitable for potable water distribution, irrigatioand drainage systems.
