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.

CPVC can be used on both hot and cold lines, while PVC is for cold water only. PVC is frequently used as a drainpipe.

CPVC solvent cement can be used on CPVC and PVC pipe. PVC solvent cement can only be used on PVC pipe. PVC stands for poly vinyl chloride. CPVC stand for Chlorinated poly vinyl chloride. CPVC is harder, stronger pipe. It requires a stronger solvent cement than PVC pipe. CPVC solvent cement is strong enough to bond CPVC pipe and fittings, so it is strong enough to bond PVC pipe and fittings as well.

A benefit of CPVC pipe is that numerous, inexpensive choices of cutting tools are available to the installer. CPVC piping has for years been cut by fine-tooth saws. The preferred method is the circular tubing cutter, modified with a plastic cutting blade. This cutter assures a square, clean cut each time and is extermely efficient in terms of labor. alternative method is the ratchet cutter.

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.

We have other CPVC brand known as Astral FlowGuard. CPVC pipes available from ?" to 2" (Copper Tube Size). You can easily join Astral Aquarius PVC pipe (Iron Pipe Size) with Astral Flow Guard CPVC pipe (CTS) with suitable Transition fittings. Transition of CTS to IPS or IPS to CTS is easily possible with our one step solvent cement. All information contained in this manual is given in good faith and believed to be accurate and reliable.

Teflon? tape is always safe and effective with CPVC. If you wish to use a paste or pipe dope, always check with the manufacturer for a recommendation because some pastes or dopes contain solvents that may be incompatible with CPVC. CPVC solvent cement should always be for CPVC piping and manufactured to meet the requirements of ATM F 493. Purple primer manufactured for PVC pipe is acceptable. Faster flashing CPVC primer is available, and is recommended for cold weather installations.

Yes, but you should watch the cost of fittings and plastic must be supported every two feet. Do not substitute fittings with Radiantec tubing. If you are using an open system, be sure that the materials are rated potable. All Radiantec polyethylene tubing is highly resistant to nearly everything. The reactivity charts show only a slight reaction to fuming nitric acid (above 1700° F)

Copper tube size (CTS) CPVC is designed for use in hot-and-cold-water distribution systems. CPVC systems are ideal for all potable water piping requirements in typical residential (single and multi-family), motel/hotel, mobile home, manufactured housing, light commercial, and institutional structures. CPVC systems conforming to ASTM D2846 are rated for continuous service at 100 psi and 180 degrees F and are marked accordingly.

PVC has an impressive record of long-term durability. When water utility managers and engineering firms were surveyed in a study sponsored by the American Water Works Association Research Foundation (AWWARF), they cited corrosion resistance, longevity and durability as their top reasons for choosing PVC. When these same water supply professionals were asked to rank PVC against the other common types of pressure pipes for life expectancy, PVC ranked first. [Source: Moser, A.P.

This question probably has as many answers as there are pipe smokers. Every smoker has to find the best method for them, but there are some good basic guidelines. The bowl should be packed gently in stages. The ideal fill is even and consistently dense from top to bottom. That's the idea behind the old saw, "Tamp the first pinch with the hand of a child, the second with the hand of a woman, and the final pinch with a manly touch." When done properly, a consistent fill is assured.

Before purchasing the program, you can try out the free demo version of the program, which allows access to all program features with sample data files. Tutorials take you step-by-step through several analyses of these sample files. These tutorials along with several articles are available on our website. Upon purchase of the program users can download a 200 page User's Guide that covers a wide range of topics on Latent Class Analysis and Latent GOLD® .

The standard version of Latent GOLD® can handle ASCII Text data formats as well as SPSS files. The DBMS copy version of the program can handle over 80 different file formats, including spreadsheets and SAS files.

SAS Export can create an SPSS .sav file which can be opened by Latent GOLD®. The SAS Documentation illustrates the Export function. View the Relevant Export page for instructions.

An Up pipe is the pipe that leads from the exhaust header collector up to the turbocharger. A down pipe leads from the exhaust side of the turbocharger down to meet the midpipe of the exhaust. The Midpipe is the center pipe leading from the catalytic convertor or downpipe to the exhaust cannister.

Yes, PVC pipe can withstand vacuum pressures. According to research conducted by Dr. R.K. Watkins at Utah State University, vacuum pressures cannot collapse an underground PVC pipe that is properly encased in a soil envelope and exposed to normal service temperatures. In fact, quick calculations show that even under conditions of elevated operating temperatures of 100oF, the pressure required to collapse most PVC pipe is greater than atmospheric.

Yes. CPVC can be installed at least 25% more quickly than copper or iron systems. Financial savings are also realized with regard to lower tool costs and insurance advantages. Considering the frequent rise and fall of the copper price structure, CPVC offers a continuing material cost advantage, often as much as a full 30% savings.

A CTS CPVC system will use the same size pipe that a copper system would, providing a full bore flow system. In general an IPS CPVC system will use the same size pipe as an iron system. CPVC piping will expand about 4 inches per 100 feet with a 100 degree F temperature change. The fact that CPVC has higher thermal expansion than metals has led to some concern.

When using CPVC with joints under slab, YOU MUST PRESSURE TEST THE SYSTEM BEFORE POURING THE SLAB. Also, it is wise to use 1" foam insulation pipe sleeve at changes in direction, where the pipe comes out of the slab, and at construction joints. The pipe should be evenly supported in smooth bottom trenches. The backfill should be free of rocks and debris. Provide some protection from abuse during the construction phase for the pipe where it emerges from the slab.

Gasketed-joint PVC provides many advantages over other types of joining systems. The following is a brief summary: Watertight Joints: Gasketed-joint PVC water and sewer pipe joints are virtually leak-free, enabling them to easily pass post-installation air tests or leakage tests. Installation Considerations: Ease in installation is another advantage gasketed-joint PVC offers.
