INSTALLATION GUIDE

CUTTING :
In order to make a proper and neat joint, measure the pipe length accurately and make a small mark. Ensure that the pipe and fittings are size compatible. You can easily cut with a wheel type plastic pipe cutter or hacksaw blade. Cutting tubing as squarely as possible provides optimal bonding area within a joint.

DEBURRING / BEVELING :
Burrs and filings can prevent proper contact between tube and fitting during assembly and should be removed from the outside and inside of the pipe. Debarking tool, pocket knife or file are suitable for this. A slight bevel on the end of the tubing will ease entry of the tubing into the fitting socket.

FITTING PREPARATION :
Using a clean, dry rag, wipe dirt and moisture from the fitting sockets and tubing end. The tubing should make contact with the socket wall 1/3 to 2/3 of the way into the fitting socket.
 
SOLVENT CEMENT APPLICATION :
Use only CPVC cement or an all - purpose cement conforming to ASTM F 493 or joint failure may result. When making a joint, apply a heavy, even coat of cement to the pipe end. Use the same applicator without additional cement to apply a thin coat inside the fitting socket. Too much cement can cause clogged water ways.

ASSEMBLY :
Immediately insert the tubing into the fitting socket, rotate the tube 1/4 to 1/2 turn while inserting. This motion ensures and even distribution of cement within the joint. Properly align the fittings. Hold the assembly for approximately 10 seconds, allowing the joint to set-up.
 
SET AND CURE TIMES :
Solvent cement set and cure times are a function of pipe size, temperature and relative humidity. Curing time is shorter for drier environments, smaller sizes and higher temperatures. It requires 10 to 20 minutes for perfect joint.

 

Note : For sizes above 65 mm (2 1/2") use IPS 70 primer before applying solvent cement. The purpose of a primer is to penetrate and soften the surfaces so they can stick together. The proper use of a primer ensures that the surfaces are prepared for fusion in a wide variety of weather conditions.


BEFORE BEGINNING :

1. Verify the cement is the same as the pipes and fittings being used.
2. Check the temperature where the cementing will take place.
- Cement take longer time to set up in cold weather. Be sure to allow extra time for curing. Do not try to speed up the cure by artificial means - this could cause porosity and blisters in the cement film.
- Solvents evaporate faster in warm weather. Work quickly to avoid the cement setting up before the joint is assembled. Keep the cement as cool as possible. Try to stay out of direct sunlight.
3. Keep the lid on cements, cleaner, and primers when not is use. Evaporation of the solvent will effect the cement.
4. Stir or shake cement before using.
5. Use 20 mm (3/4") dauber on small diameter pipes, 40 mm (1 1/2") dauber up through 80 mm (3") pipe, and a natural bristle brush, swab, or roller 1/2 the pipe diameter on pipes 4"and up.
6. Do not mix cleaner or primer with cement.
7. Do not use thickened or lumpy cement. It should be like the consistency of syrup or honey.
8. Do not handle joints immediately after assembly.
9. Do not allow daubers to dry out.
10. Maximum temperature allowable for CPVC pipe is 180°F.
11. All colored cements, primers, and cleaners will have a permanent stain. There is no know cleaning agent.
12. Use according to the step outline in ASTM D-2846, joining of pipe and fittings,

SAFE HANDLING OF SOLVENT CEMENT

When using solvent cements, primers and cleaners there are some basic safety measures. All users should keep in mind.
- Avoid prolonged breathing of solvent vapors. When pipe and fittings are being joined in enclosed areas, the use of ventilating devices are advised
- Keep cements, primers and cleaners away from all sources of ignition, heat, sparks and
open flame.
- Keep containers of cements, primers and cleaners tightly closed except when the product is being used.
- Dispose of all rags used with solvents in a proper outdoor waste receptacle.
- Avoid eye and skin contact. In case of eye contact, flush with plenty of water for 15 minutes and call a physician.

 

FAQ's

1.    What is Astral CPVC Pipe?
Noveon, Inc., the world leader in CPVC technology, invented CPVC more than 40 years ago. Astral CPVC is a patented rigid thermoplastic chlorinated polyvinyl compound used in the manufacturing of a plumbing system that won't pit, scale or corrode.


2.    When was a CPVC plumbing system first used?
The first CPVC plumbing system was installed in 1959. Since its development, more than three billion feet of CPVC pipe has been installed in homes, condominiums, buildings, apartments and hotels, including 12 million homes.


3.    Do Astral CPVC plumbing systems meet plumbing codes?
CPVC plumbing systems meet all model code approvals, including BOCA National Plumbing Code, Standard Plumbing Code, Uniform Plumbing Code, CABO 1- and 2- Family Dwelling Code, Canadian Plumbing Code, International Plumbing Code and International Residential Code, as well as California Plumbing Code.


4.    Why would a plumber, builder or homeowner select a Astral CPVC plumbing system over a metal (copper or galvanized) system?
CPVC plumbing systems will not pit, scale or corrode in aggressive water and soil conditions, so water purity is maintained. In environments with aggressive water, pH levels of less than 6.5, copper plumbing is not certified to ANSI/NSF Standard 61 for drinking water safety and may break down. Plus, copper cannot resist certain soil chemistries or compositions and will begin to degrade. In these conditions, copper pipes can develop pinholes and leaks in just a few years.


5.    What are the additional benefits of a Astral CPVC plumbing system for homeowners?
The thermoplastic properties of a Astral CPVC system provides a system that is four times quieter than copper plumbing systems, reducing the sound of running water and the potential of the pounding noise of water hammer. In addition, unlike copper piping materials, the thermoplastic properties of a Astral CPVC plumbing systems provide insulation to reduce condensation and "sweaty pipes." The material keeps hot water hotter and cold water colder than copper. Less energy is lost through the wall of the pipe, saving homeowners money on heating and cooling.


6.    What are the additional benefits for builders and plumbers?
The benefits of a Astral CPVC plumbing system versus copper plumbing systems are not just a matter of lower material costs. Astral CPVC plumbing systems are faster and easier to install for the experienced, professional plumber, reducing overall labor costs. Astral CPVC plumbing systems do not require torches or heavy equipment. A one-step joining system can provide curing in 10 minutes on standard size pipe for ease in pressure testing

Are there any health risks using a Astral CPVC plumbing system?
No, Astral CPVC plumbing systems have been used for more than 40 years and have not posed any health risks. Astral CPVC plumbing systems exceed ANSI/NSF Standard 61 for water quality with no pH level restrictions as found in copper pipe. Astral CPVC plumbing systems meet all model code approvals, including the International Plumbing Code, International Residential Code, BOCA National Plumbing Code, Standard Plumbing Code, Uniform Plumbing Code, CABO-1 and 2-Family Dwelling Code and Canadian Plumbing Code.


7.    What are the combustibility properties of Astral CPVC pipe and fittings?
Astral CPVC has a flash ignition temperature of 900°F which is the lowest temperature at which sufficient combustion gas is evolved that can be ignited by a small external flame. Many other ordinary combustibles, such as wood, ignite at 500°F or less.

Astral CPVC will not sustain burning. It must be forced to burn due to its very high Limiting Oxygen Index (LOI) of 60. LOI is the percentage of oxygen needed in an atmosphere to support combustion. Since the Earth's atmosphere is only 21% oxygen, Astral CPVC will not burn unless a flame is constantly applied, and stops burning when the ignition source is removed.

Astral CPVC has a significantly lower heat of combustion at 7,770 BTU/lb compared to Douglas fir at 9,040 BTU/lb and polypropylene at nearly 20,000 BTU/lb. Materials with a high heat of combustion perpetuate a combustible mixture which, when ignited, creates more heat and causes the burning process to become self-sustaining. Astral CPVC cannot be the ignition source of a fire or support combustion.
