Does CPVC need to be insulated?

CPVC pipe systems do not require insulation. Insulating CPVC pipe is reserved as a recommendation to aid pipes exposed to sub-freezing temperatures. Hot water CPVC pipes also can be insulated to aid in heat / energy retention in the system.

What causes CPVC to crack?

Among the many causes of CPVC failures, and the ensuing water damage claims, are raw material flaws, manufacturing defects, inadequate warnings, improper shipping and handling practices, system design issues, poor installation practices, incorrect maintenance, and chemical attack.

Do you have to wrap PVC pipe?

Plastic pipes should only be wrapped with automatic heat tape. This kind of tape is insulated with heavy rubber around its wires.

How do you protect above ground PVC pipe?

Coating the pipe in an opaque shield prevents UV degradation. Painting with light-colored acrylic or latex (water-based) paint is the most common method used to protect above ground PVC and CPVC pipe from UV degradation. Preparation of the surface is extremely important when it is to be painted.

What temperature can CPVC pipe withstand?

200°F
CPVC’s superior temperature resistance is exhibited in the ASTM standards for each material, as the maximum service temperature for PVC is up to 140°F (60°C) and for CPVC it is up to 200°F (93.3°C). Note: Be sure to check with the manufacturer to check their product’s individual operating capabilities.

What temperature does CPVC freeze?

Like most materials, PVC and CPVC become more brittle at low temperatures, particularly at temperatures below freezing (32°F).

What can you wrap your pipes with?

Simply take some old rags or towels, and wrap them around any exposed pipes, spigots or other areas that you think is susceptible to freezing. Make sure it’s wrapped up tight and won’t come loose during a storm. The best option is to wrap duct tape around the towel.

Is CPVC good for outdoor use?

PVC and CPVC piping products have been used successfully in outdoor applications when proper recommendations are followed. As with any other piping, the system must be protected from freezing in applications subject to colder temperatures.

Is PVC and CPVC pipe UV resistant?

Harvel’s Corzan compounds used in the manufacture of rigid CPVC pipe contains at least 2\% Titanium Dioxide (Ti02). Harvel’s Clear PVC piping products do not contain UV inhibitors and should not be exposed to UV radiation. Title: Is PVC and CPVC pipe UV resistant?

What is the difference between CPVC and PVC pipe pressure ratings?

CPVC and PVC piping test to the same pressure rating at 73°F (22.8°C), but as the temperature increases, CPVC maintains its pressure rating better than PVC. For example, let’s calculate the pressure rating for 10 in. Schedule 80 piping at 130°F (54.4°C) for both PVC and CPVC. Note that each material is pressure rated to 230 psi at 73°F (22.8°C).

What kind of paint do you use on PVC pipe?

Based on these studies, Harvel Plastic, Inc. recommends that PVC and CPVC piping products (i.e. pipe, duct, & shapes) exposed to the direct effects of UV radiation be painted with a light colored acrylic or latex paint that is chemically compatible with the PVC/CPVC products.

What is the maximum temperature that CPVC can withstand?

CPVC’s superior temperature resistance is exhibited in the ASTM standards for each material, as the maximum service temperature for PVC is up to 140°F (60°C) and for CPVC it is up to 200°F (93.3°C).
