CPVC piping systems are used for industrial applications, column and pressure piping systems and for other for agriculture applications. We embrace the latest international technology and provide quality piping solutions made for varied needs of the markets. Chlorinated Polyvinyl Chloride (CPVC) is a thermoplastic pipe material. It is nationally accepted since 1982 and has many benefits when compared with other plumbing materials. It is primarily used for supplying hot and cold potable water and in industrial liquid applications.
CPVC pipe has a number of features that make it an improvement over standard PVC piping. It offers greater heat resistance, withstanding corrosive water temperatures between 70°F and 90°F higher than PVC. CPVC is non-toxic, while PVC may leach toxins into the water at increased temperatures. CPVC also offers greater strength and flexibility, while PVC is far less ductile.
CPVC pipe has become a modern standard for water supply and liquid lines because of its cost saving benefits over metal piping. It is less expensive than copper piping and materials, as well as being lighter, making it faster and easier to install, saving on labour costs. The thermal conductivity of copper pipe is 2500 times greater than CPVC pipe, meaning it provides significant energy savings while keeping water hotter longer.
Corrosion Resistance: Panchakanya Durastream CPVC gives excellent resistance even under the harshest of water conditions so there are none of the purity worries from corrosion of metal pipe or soldered joints. Panchakanya Durastream CPVC pipe keeps pure water pure.
Low Bacterial Growth: Bacteria build up with CPVC is far lower than with alternative piping materials–Copper, steel and other thermoplastics.
Tough Rigid Material: Panchakanya Durastream CPVC pipe has a much higher strength than other thermoplastics used in plumbing. This means that CPVC needs less hangers and supports and there is no unsightly looping of the pipe. Panchakanya Durastream CPVC pipe has a higher pressure bearing capability. This leads to the same flow rate with a smaller pipe size.
No Scale, pit or leach formation: Even after years of use in the most aggressive conditions, Panchakanya Durastream CPVC pipe won’t corrode, standing up to low PH water, Coastal salt-air exposure and corrosive soils. Panchakanya Durastream CPVC Pipe stays as solid and reliable as the day it was installed. It maintains full water carrying capacity because it's scale resistance means no build up to cause water pressure loss.
Unaffected by Chlorine in the water: Some materials maybe adversely by chlorine contained in the water supply, which can cause breakdown of the polymer chains and potential leaks. In this respect, Panchakanya CPVC pipe is unaffected by the chlorine present in potable water supply.
Chemical Resistance: CPVC has excellent chemical resistance to strong mineral acid sand bases.
Low Thermal Expansion: Panchakanya Durastream CPVC pipe has a lower co-efficient of thermal expansion than alternative plastics, reducing the amount that the pipe expands when hot water is running, again reducing unsightly ‘looping’ of the pipe.
Easy, Cold welding process: CPVC uses a simple, solvent cement joining method. Tools required are very simple and inexpensive (Chamfering tool and pipe cutter only) and avoid the need for an electrical source.
Superior Insulation: Panchakanya Durastream CPVC pipe is more energy efficient than metal pipe. As an insulator it does not lose heat the way metal pipe do. Heat loss and thermal expansion are reduced.
Hot & Cold Water Compatible: Panchakanya Durastream CPVC pipe is compatible with both hot and cold water. It withstands very high temperature compared to any other thermoplastic plumbing systems. Many solar and electric water heaters have CPVC piping system for heat efficiency and lower installation cost.
Fire Safety: CPVC has a limiting Oxygen Index (LOI) of 60. Thus in air, Panchakanya Durastream CPVC pipe does not support combustion. No flaming drips, does not increase the fire load, low flame spread, low smoke generation.
Approved Worldwide: CPVC plumbing system is approved for contact with potable water in wide range of countries including USA, UK, Canada, Germany, France, The Netherlands and Middle East among others
Cost Effective: CPVC Plumbing System is very cost effective than any other plumbing systems. It saves cost on fittings, loops, anchors, off-sets, insulation, labour and expensive tools. Moreover CPVC plumbing systems last longer more than 50 years

Panchakanya Durastream CPVC pipes & fittings are the one of the pioneer product of Panchakanya Group. Panchakanya CPVC pipes and fittings are made from the special thermoplastic, chemically known as chlorinated polyvinyl chloride(CPVC)
These pipes are manufactured from our state of the art machinery in Copper Tube Size (CTS) ranging from ½” to 2” in two different Standard Dimension Ratio SDRi.e.11 & SDR–13.5 as per the standard of ASTMD–2846 to meet the international standard.
Apart from having the same physical properties, SDR11&SDR13.5 comes with different wall thickness & therefore, at any given temperature, they have different pressure ratings. For e.g.
Pipe Temperature (⁰C) Pressure Rating

Don’ts:
Panchakanya CPVC Pipes & Fittings Installation Procedure:
CUTTING:
Panchakanya Dura stream CPVC pipe can be easily cut with a wheel– type plastic pipe cutter, ratchet cutter or fine tooth saw. Ratchet cutters should be sharpened regularly. When saw cutting, a miter box should be used to ensure a square cut. Cutting pipe as squarely as possible provides optimal bonding area within a joint. If any indication of damage or cracking is evident at the pipe end, cut off atleast 2 inches beyond any visible crack.
DEBURRING/BEVELING:
Burr sand fitting scan prevent proper contact between pipe and fitting during assembly and should be removed from the outside and inside of the pipe. A chamfering tool is preferred, but a pocket knife or files area is suitable for this purpose. A slight bevel on the end of the pipe will ease entry of the pipe into the fitting socket and minimize the chances of pushing solvent cement to the bottom of the joint.
FITTING PREPARATION:
Using a clean, dry rag, wipe dirt and moisture from the fitting socket sand pipe end. Check the dry fit of the pipe and fitting. The pipe should make contact with the socket wall 1/3 to 2/3 of the way into the fitting socket. At this stage, pipe should not bottom out in the socket.
SOLVENT CEMENT APPLICATION:
Use only CPVC cement conforming to ASTMF 493 or joint failure may occur. Yellow one – step cement may be used without primer. If a primer is required by local plumbing codes, a primer conforming to ASTMF 656 should be used. When making a joint, apply full even layer of cement on the pipe O.D. for a distance slightly greater than the depth of the socket of the fitting. Coat the fitting socket with a medium layer of cement avoiding pudding inside the system. Apply a second full even layer of cement on the pipe O.D. Too much cement can cause clogged water ways.
ASSEMBLY:
Immediately insert the pipe into the fitting socket, rotating the pipe ¼ to ½ turn while inserting. This motion ensures an even distribution of cement with the joint. Properly align the fitting. Hold the assembly for approximately 10 seconds, allowing the joint to set-up. An even bead of cement should be visible around the joint. If this bead is not continuous around the socket edge, it may indicate that insufficient cement was applied. In this case, remake the joint avoid potential leaks. Wipe excess cement from the pipe and fittings surface for an attractive, professional appearance.
SET & CURE TIMES:
A joint which has cured sufficiently to pressure test may not exhibit it's full joint strength. Solvent cement set and cure times are function of a pipe size, temperature and relative humidity. Curing time is shorter for drier environments, smaller sizes and higher temperatures. Refer to the following table for minimum cure times after the last joint has been made been made before pressure testing can begin. Use of primer and/or presence of hot water extend cure time required for pressure testing.

| Pipe | Ambient Temperature During Cure Period | |||
|---|---|---|---|---|
| 60⁰F | 40⁰F | 32⁰F | 0⁰F | |
| ½” | 10 min. | 10 min. | 15 min | 30 min. |
| ¾” | 10 | 15 | 15 | 30 |
| 1” | 10 | 15 | 20 | 30 |
| 1 ¼” | 10 | 15 | 20 | 30 |
| 1 ½” | 15 | 15 | 30 | 45 |
| 2” | 15 | 15 | 30 | 60 |
Special Care should be exercised when assembling Panchakanya Dura stream CPVC system in extremely low temperatures (below 40⁰F) or extremely high temperatures (above 100⁰F). In extremely hot temperatures, make sure both surfaces to be joined are still wet with cement when putting them together.
