Five Tips On How To Fix Polypropylene Piping

Updated: Dec 12, 2022

Industrial-grade polypropylene piping is a dependable material for chemical plants, but it's not immune from wear and tear. With proper maintenance and repair, industrial-grade polypropylene piping can last for years in demanding conditions. Here are five tips to help you fix industrial-grade polypropylene piping at your chemical plant.

1. Clean the Area: Before you begin any repair work, make sure that the area is clean and free of debris. This will ensure that your repairs are successful and won’t be compromised by dirt or other materials.

2. Replace Damaged Sections: If there are sections of the pipe that are damaged beyond repair, you may need to replace them with new sections. Make sure that the new pieces fit properly and securely before proceeding with the repair.

3. Use Adhesive for Sealing: Industrial-grade polypropylene is typically sealed using adhesive rather than heat or mechanical seals. Look for a high-quality adhesive that is specifically designed for use with polypropylene pipe.

4. Use Heat Gun for Joining: When joining pipes together, a heat gun can be used to soften and shape the pipe, allowing for a more secure connection. Be sure to follow all safety precautions when using a heat gun.

5. Test for Leaks: After any repairs have been made, it’s important to test the piping system for leaks or other issues before putting it back into service. This can be done using a pressure test with air or water, depending on what is required by your facility’s regulatory body.

By following these steps, you can ensure that your industrial-grade polypropylene piping is properly repaired and will last for years in demanding conditions at your chemical plant.
