At KGPlastochem, we are proud dealers of Plastochem Adhesives, Inc., a pioneer and leading manufacturer of solvent cements, primers, and cleaners for PVC, UPVC, CPVC, ABS, and other plastic piping systems. Plastochem products are globally recognized for their premium quality in joining plastic pipes and fittings.
In this guide, we outline the recommended steps for using Plastochem Solvent Cement for PVC piping systems. Before beginning the installation, ensure you have all the necessary tools, products, and applicators required for the job.
Step-by-Step Guide to Joining PVC Pipes Using Solvent Cement
1. Prepare the Pipe and Fitting
- Cut the pipe squarely to the required length.
- Deburr or bevel the edges at a 10-15 degree angle.
- Ensure all joining surfaces are clean and dry, free from dust and contaminants.
2. Check the Dry Fit
- Insert the pipe into the fitting to test the fit.
- The fitting should slide easily over the pipe end but become tight about halfway through.
- A snug fit is crucial, especially for systems requiring quick pressurization.
3. Select the Right Applicator
- Use an applicator that is at least half the pipe’s diameter.
- For large pipe sizes, use a swab or roller to ensure even application.
4. Wear Safety Gear
- Put on safety glasses and nitrile gloves before handling solvent cement.
- Solvent cements are flammable—keep them away from sparks, flames, heat, and ignition sources.
5. Apply Primer (If Required)
- If local codes require, apply Plastochem Primer to the pipe and fitting.
- Rotate the primer applicator at least 10 times around the pipe.
- For non-pressure systems, primer may not be necessary if local regulations allow.
6. Apply Solvent Cement
- Quickly apply a full, even layer of solvent cement to the pipe, covering the depth of the socket.
- Apply a medium layer to the fitting’s socket.
- Avoid excess application and puddling.
- Apply a second layer of cement to the pipe.
- Rotate the applicator at least 10 times around the pipe.
- Prevent cement from running inside the pipe or fitting.
7. Assemble and Hold in Place
- Immediately join the pipe and fitting while the cement is still wet.
- If the cement is not fully wet, reapply before assembling.
- Twist the pipe 1/8 to 1/4 turn as you insert it until it reaches the stop.
- Hold the joint firmly for about 30 seconds to prevent pushout.
- Wipe away any excess cement.
8. Curing Time
- Allow at least 5 minutes for handling strength.
- Allow 30 minutes of curing time for up to 160 psi pressure, for pipe sizes up to 2” at 60°F (16°C) or higher.
- For larger pipes, higher pressure, or lower temperatures, extend the curing time accordingly.
Important Notes:
- Primer is highly recommended as it softens the PVC surface, allowing the cement to create a stronger bond.
- Always read the labels and Safety Data Sheets (SDS) before using any cement or primer.
