PPH Pipe Fittings

PPH Pipeline System Valve Accessories

PPH, or Polypropylene Homopolymer, is a specially enhanced variant of propylene featuring a crystalline structure. As a member of the broader polypropylene (PP) family, PPH distinguishes itself through superior impact and thermal resilience, excellent pressure and chemical resistance, as well as an extended service life. Its hydrostatic strength is also notably higher than that of other materials. These attributes make PPH a go-to choice in industries like chemical processing, electronics, and wastewater treatment, attributed to its long service life and robust performance.

PPH Piping System: Installation Guidelines and Best Practices

PPH (polyvinylidene fluoride) pipes are known for their long-term availability in the temperature range of -20 ℃ to+100 ℃. They are widely used in key production fields such as light chemical industry, chemical reaction transportation, and various chemical wastewater treatment and purification. To ensure that the pressure system is leak free and stable, PPH pipelines are usually installed using hot melt welding.

Installing PPH (Polypropylene Homopolymer) pipes involves several crucial steps to ensure optimal performance and longevity. Here’s a brief guide on best practices for PPH pipe installation:

Pre-Installation Steps

Material Inspection: Verify the quality and specifications of PPH pipes and fittings to be used.
Tool Preparation: Gather all necessary tools like pipe cutters, welding machines, and measuring instruments.
Installation Steps
Cutting: Cut the pipe to the required length, ensuring that the cut is square to the pipe’s axis. Specialized pipe cutters are recommended for this task.
Deburring: Remove any burrs or uneven edges from the cut pipe end to ensure a smooth connection.
Marking: Mark the insertion depth on the pipe to guide during the fusion process.
Cleaning: Wipe the pipe ends and the inner surface of the fittings to remove any dirt or contaminants.
Fusion Welding: Align the pipe and fittings in the welding machine and follow the welding parameters like temperature and time as per manufacturer guidelines.
Cooling: Allow the welded joint to cool down naturally before subjecting it to any stress or pressure testing.
Testing: Conduct pressure and leak tests to verify the integrity of the installation.
Post-Installation
Documentation: Keep records of all installation details including welding parameters, test results, and any observed anomalies for future reference.

PPH uses hot melt welding like HDPE. The following is a video of HDPE hot melt welding operation.

Inspection: Periodically inspect the installed pipes for any signs of wear, leakage, or other issues.
Safety Precautions
Always adhere to safety guidelines and use appropriate personal protective equipment.
Ensure the installation site is well-ventilated, especially when using welding machines.
By following these best practices, you can ensure a reliable and efficient PPH piping system that meets industrial standards and requirements.
