PVC SDR Pressure System

Scope: This specification covers PVC Standard Dimensional Ratio (SDR) pipe and solvent cement fittings for pressure applications. This system is intended for pressure applications where the operating temperature will not exceed 140°F.

Specification: Pipe and fittings shall be manufactured from virgin rigid PVC (polyvinyl chloride) vinyl compounds with a Cell Class of 12454-B as identified in ASTM D-1784.

PVC SDR pipe shall be Iron Pipe Size (IPS) conforming to ASTM D-2241 for plain end pipe and ASTM 2672 for belled-end pipe. PVC Schedule 40 (IPS) solvent cement fittings shall conform to ASTM D-2466. Pipe and fittings shall be manufactured to the nominal dimension cited in the applicable ASTM standard, and shall be made by one manufacturer. Fittings shall be injection molded. Fabricated fittings shall not be permitted. All pipe and fittings shall be manufactured in the United States. Pipe and fittings shall conform to National Sanitation Foundation (NSF) Standard 61 and NSF Standard 14.

Installation shall comply with the latest installation instructions published by Charlotte Pipe and Foundry and shall conform to all local plumbing, building, and fire code requirements. Solvent cement joints shall be made in a two step process with primer manufactured for thermoplastic piping systems and solvent cement conforming to ASTM D-2564. The system shall be protected from chemical agents, fire stopping materials, thread sealant, plasticized vinyl products, or other aggressive chemical agents not compatible with PVC compounds. Systems shall be hydrostatically tested after installation. Testing with compressed gas is not recommended.
