What is PPR Pipe 40mm DADEX polydex thermoline ?
PPR Pipe 40mm DADEX Polydex Thermoline PN 20 is a polypropylene random copolymer (PPRc) pipe manufactured by Dadex, a leading Pakistani producer, designed for robust performance in HVAC systems and hot/cold water distribution. This 40mm outer diameter pipe carries a PN 20 pressure rating, making it suitable for high-demand applications with standard 4-meter lengths for easy handling and installation. It aligns with your interest in reliable, locally sourced plumbing materials for building services in Pakistan.
Description
The pipe features a smooth inner wall for optimal flow, antimicrobial properties in select variants to inhibit bacteria growth, and green or gray coloring typical of Dadex Polydex/Thermoline lines. Wall thickness is approximately 6.7mm for the 40mm size, ensuring structural integrity under pressure.

Usage
Perfect for HVAC chilled/hot water circuits, radiant heating, domestic hot/cold water supply, and compressed air lines in buildings, leveraging low thermal conductivity (0.24 W/mK) for energy efficiency. In Rawalpindi projects, pair with PN 20-25 elbows (like prior 110mm EG query) for seismic-prone areas and agriculture; store away from UV and use sleeves outdoors. Locally available via Dadex distributors, ideal for your procurement needs.
