CPVC Pipe FAQ
What is the maximum temperature for CPVC pipe applications?
Our CPVC pipes are rated for continuous service at temperatures up to 200°F (93°C). The maximum intermittent temperature can reach 210°F (99°C) for short periods. For hot water applications, CPVC pipe maintains its structural integrity much better than standard PVC pipes, which are only rated to 140°F (60°C).
How does CPVC pipe compare to copper piping?
CPVC pipe offers several advantages over copper piping. It's more cost-effective, easier to install (requiring solvent cement rather than soldering), and completely resistant to scale buildup and corrosion. CPVC also has better insulation properties, reducing heat loss in hot water lines. Unlike copper, CPVC won't develop pinhole leaks from corrosion and doesn't require grounding in electrical systems.
Can CPVC pipe be used for outdoor applications?
Yes, CPVC pipe can be used outdoors, but requires protection from direct sunlight. Prolonged UV exposure can degrade CPVC material over time. For outdoor installations, we recommend painting the pipes with a latex-based paint or using UV-resistant pipe wrap. Above-ground outdoor installations should be properly supported to account for thermal expansion and contraction.
Additional CPVC Pipe Information
Our CPVC pipe system includes a complete range of fittings, valves, and accessories to create a fully integrated plumbing solution. The material meets all requirements of ASTM D1784, ASTM D2846, and CSA B137.6 standards for chlorinated polyvinyl chloride pressure piping systems.
Installation Guidelines
- Cut pipes square using a fine-tooth saw
- Deburr pipe ends after cutting
- Use only approved CPVC solvent cements
- Allow proper cure time before pressurizing
- Support pipes every 4 feet for horizontal runs
More CPVC Pipe FAQ
What chemicals are compatible with CPVC pipe?
CPVC pipe demonstrates excellent resistance to many acids, bases, salts, and aliphatic hydrocarbons. It's particularly suitable for handling dilute mineral acids, alkaline solutions, and many corrosive salts that would damage metal pipes. However, CPVC is not recommended for use with aromatic hydrocarbons, chlorinated hydrocarbons, or concentrated oxidizing acids. Always consult our chemical resistance chart for specific applications.
How long does CPVC pipe last?
Properly installed CPVC pipe systems typically last 50+ years in residential applications. In industrial settings with proper chemical compatibility, service life of 25-40 years is common. The actual lifespan depends on operating conditions, including temperature, pressure, and chemical exposure. CPVC doesn't corrode or scale like metal pipes, maintaining full flow capacity throughout its service life.
Is CPVC pipe safe for drinking water?
Yes, our CPVC pipes are NSF/ANSI 61 certified for potable water applications. They meet all requirements for safe drinking water delivery and don't leach harmful substances into the water supply. CPVC pipes are widely used in residential plumbing and have been approved by all major plumbing codes for hot and cold water distribution.
CPVC Pipe Applications
- Residential hot and cold water distribution
- Industrial process piping
- Chemical processing plants
- Fire sprinkler systems
- Irrigation systems
- Water treatment facilities
Final CPVC Pipe FAQ
What's the difference between Schedule 40 and Schedule 80 CPVC pipe?
Schedule 80 CPVC pipe has thicker walls than Schedule 40, making it stronger and able to handle higher pressures. Schedule 40 is typically used for residential and light commercial applications, while Schedule 80 is preferred for industrial settings with higher pressure requirements. Both share the same outside diameters, but Schedule 80 has reduced inside diameters due to thicker walls.
How do you join CPVC pipe?
CPVC pipe is joined using solvent cement welding. The process involves applying primer (for some cement types) and then CPVC-specific solvent cement to both the pipe end and fitting socket. The pieces are then quickly joined with a quarter-turn twist to ensure even distribution of the cement. Properly done, this creates a permanent, leak-proof joint that's actually stronger than the pipe itself.
Does CPVC pipe require insulation?
While CPVC pipe has lower thermal conductivity than metal pipes, insulation is recommended in certain situations. Hot water lines should be insulated to conserve energy and maintain water temperature. Cold water lines in unconditioned spaces should be insulated to prevent condensation. In freezing climates, both hot and cold lines in unheated areas require insulation to prevent freezing.
