This write-up was initially published in July of 2017, and also has to be updated with an ext information and also resources, including a solvent cement share burst check video.

You are watching: Can i use cpvc cement on pvc

Solvent cement is no glue. Rather it is a fast, basic installation process that uses solvents and also resin come chemically fuse the pipe and fitting together at a molecule level, essentially developing one continuous piece of plastic. In fact, solvent cement is the only joining an approach recommended for system functions like expansion loops because it enables the pipe to bend and also move there is no breaking or weakening the share seal.

To for sure the solvent cement is used properly throughout your procedure system, we"ve put together the adhering to dos and don’ts to remember throughout the seven step involvement process.

If the provided solvent cement environment do"s and don"ts space followed, see how reliable the joints become by the town hall the explode test video below.

CPVC Solvent Cement Welded joint Burst Test


*

1. Cutting CPVC

Do: Use tools designed for use v plastic pipe and also fittings.

Preferred plastic cut tools include a ratchet cutter, wheel-type plastic pipe cutter, a power saw, or a fine-toothed saw.

Do: for sure the CPVC is cut squarely by utilizing a miter box.

Cutting the pipe as squarely as feasible provides the best bonding surface area. The an ext surface area that becomes chemically bonded, the more strength the joint will exhibit.Don’t: usage a dull or broken cutting device blade.

2. Chamfering and also Deburring CPVC

*

Do: eliminate burrs and filings.

Burrs and also filings deserve to prevent ideal contact in between the pipe and also fitting and also may placed undue anxiety on the pipe and also fitting assembly. Use a chamfering device or file to remove burrs and also filings indigenous the outside and also inside of the pipe.

Do: place a slim bevel at the finish of the pipe.

A slim bevel eases entry of the pipe into the socket and minimizes the possibility of clean everything solvent cement native the fitting. Because that pipe size 2 in. And larger, a 10 to 15° chamfer of 3/32 in. Is recommended.

3. Preparing the Fitting for Solvent Cement

Do: with a clean, dry rag, wipe any loosened soil and moisture native the fitting socket and the pipe end.

Loose soil and/or moisture have the right to slow cure times and also reduce the share strength. Make sure the right is an excellent by checking the the pipe enters the installation socket easily 1/3 to 2/3 of the depth.

Note: If the pipe bottom in the installation with small interference, shot a new fitting.

4. Inside wall Application

*

*

Do: use primer conforming come ASTM F656 and also a suitable applicator.

Primer is necessary to prepare the bonding area because that the addition of cement and also subsequent assembly. Usage a suitable applicator, such together a dauber, swab or paintbrush, approximately half the dimension of the pipe diameter.

Apply the inside wall to the inside of the installation socket and to the outiside the the pipe end. Use a 2nd primer coating inside the fitting socket. Redip the applicator as often as necessary to ensure the whole surface that both pieces is tacky.

Don"t: use a rag to use the primer.

5. Solvent Cement Application

Do: Use only solvent cement conforming come ASTM F493

Apply solvent cement as soon as the pipe surface is tacky (not wet) indigenous primer. The involvement surfaces have to be penetrated and softened.

Cement need to be applied with a natural bristle brush or swab fifty percent the dimension of the pipe diameter. Because that pipe sizes smaller sized than 2 in., a dauber might be used.

Apply a heavy, also coat of cement to the external of the pipeline end, and also a medium coat come the inside of the installation socket. Because that pipe sizes greater than 2 in., use a second coat that cement ~ above the pipe end.

*

*

Don’t: permit puddling the solvent cement in the fittings and also pipe.

Don’t: use solvent cement near sources that heat, open up flames, or once smoking.

Don’t: usage solvent cement the exceeds that shelf life or has come to be discolored or gelled.

6. Assembly

*

After cement application, automatically insert the pipe into the fitting socket if rotating a 1/8 to 1/2 revolve until the fitting-stop is reached. At this time, the fitting must be properly aligned because that installation.

The pipeline must fulfill the bottom that the installation socket. Once in place, the assembly must be hosted in ar for 10 to 30 secs to ensure initial bonding and also to prevent push out.

Do: inspect that a bead of cement is apparent around the pipe and fitting juncture.

If this bead is not consistent around the socket shoulder, the may suggest that poor cement to be applied. In this case, the fitting must be discarded and also the joint reassembled.

Wipe off any excess solvent cement v a rag.

Do: Use equipment for the involvement of a large diameter pipe.

For a 6 in. Or larger diameter pipe, a pipe puller (come-a-long) is recommended to assemble the joint and also hold it in place for the initial set time without applying excess pressure that may damage the pipe or fitting.

This equipment should be set up before the start of priming for this reason assembly have the right to happen easily while primer and also cement are still fluid.

7. Collection and cure Times

Solvent cement set and cure times room a role of pipe size, temperature, family member humidity, and also tightness of fit.

Drying time is faster for drier environments, smaller sized pipe sizes, high temperatures and also tighter fits.

The assembly need to be enabled to set, without any kind of stress top top the joint, per the time presented in the complying with tables. Complying with the initial collection period, the assembly deserve to be tackled carefully, avoiding significant stresses to the joint.

Do: monitor the recommended set times.

After a share is assembled utilizing solvent cement, it must not be disturbed for a period of time to permit for ideal “setting.” Recommended set times space as follows:

*

Do: follow the recommended cure times.

After a share is assembled making use of solvent cement, the cement must be permitted to effectively “cure” before the piping mechanism is pressurized.

Recommended minimum cure time are shown below. These recommendations must only offer as a guide since atmospheric problems during installation will impact the curing process.

Note: High humidity and/or cooler weather will certainly require much longer cure times. Typically include 50% come the recommended cure time if surroundings room humid or damp.
