Do’s and Dont’s

Do’s

Follow Panchakanya CPVC installation manual and safe work practices

Store pipes and fittings in original packaging, in a covered area

Use tools designed specifically for CPVC pipes and fittings

Conduct hydraulic pressure testing after curing and bleed air before testing

Cut at least 25mm beyond the crack if any damage is found

Ensure no sharp edges touch pipes while embedding in walls or floors

Rotate pipe 90°–180° while applying CPVC solvent cement

Use Teflon tape on all threaded fittings

Use only plastic straps for vertical & horizontal support

Dont's

Do not use metal hooks, nails, or sharp/rough straps

Do not over-tighten straps on pipes

Never expose CPVC pipes to open flame for bending

Do not drop pipes or place heavy objects on them

Never dilute solvent cement with thinners or other liquids

Avoid petroleum-based adhesives, sealants, or lubricants

Do not use air or gases for pressure testing

Do not use CPVC pipes for pneumatic applications

Do not use CPVC solvent cement that has exceeded its shelf life, is discoloured, or gelled

Installation of CPVC Pipes

Step 1: Cutting.

CPVC pipes can be cut using a wheel-type plastic pipe cutter, ratchet cutter, or fine-tooth saw. A miter box is recommended for saw cuts to ensure squareness, which is critical for optimal bonding. Any damaged or cracked ends should be cut off at least 2 inches beyond the visible crack 1.

Step 2: Deburring/Beveling.

Burrs and fittings must be removed from both the inside and outside of the pipe using a chamfering tool, pocket knife, or file. A slight bevel on the pipe end eases entry into the fitting socket and prevents pushing solvent cement to the bottom of the joint 1. .

Step 3: Prepare the CPVC pipe and fitting to be joined by removing dirt or moisture.

Step 3: Fitting Preparation.

Clean dirt and moisture from the fitting socket and pipe end with a dry rag. Check the dry fit; the pipe should contact the socket wall 1/3 to 2/3 of the way in without bottoming out 1.

Step 4: Apply the solvent cement to the pipe exterior and fitting interior.

Step 4: Solvent Cement Application.

Use CPVC cement conforming to ASTM F 493. Apply a full, even layer of cement on the pipe’s outer diameter slightly beyond the socket depth, coat the fitting socket with a medium layer, and add a second layer on the pipe. Avoid puddling inside the system to prevent clogs 1.

Step 5: Assembly.

Insert the pipe into the fitting socket immediately, rotating it ¼ to ½ turn to distribute cement evenly. Hold the assembly for about 10 seconds to set. A continuous bead of cement around the joint indicates sufficient application; if not, remake the joint. Wipe excess cement for a professional finish .

Step 6: Curing.

Allow the joint to cure for at least 15 minutes before pressure testing. Full cure times vary based on pipe size and ambient conditions, typically ranging from 10 minutes for smaller pipes to 60 minutes for larger ones. Refer to the cure time table for specific guidelines.

Cure times vary based on pipe size, ambient temperature, and humidity. The following table shows minimum cure times before pressure testing:

Ambient Temperature During Cure Period

Pipe	60°F	40°F	32°F	0°F
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.

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

Operating
Temperature	Operating
Pressure
SDR 11	27⁰C	28.14 kg/cm2
	82⁰C	7.1 kg/cm2
SDR 13.5	27⁰C	22.23 kg/cm2
	82⁰C	5.61 kg/cm2
