Key Knowledge on Installing PPR Pipe


PPR pipes and fittings have become increasingly popular due to their versatility. If you’re considering using them in your next project, this article will provide you with insights into how PPR piping systems are installed and the preparations required. Let’s dive deeper into the world of PPR piping systems.

Pre-Installation Preparation

Before installing PPR pipes, it’s crucial to consider the following:

  1. Check the product quality assurance certificate to ensure compliance with relevant standards.
  2. Inspect the pipes for defects such as bubbles, cracks, or grooves on the surface.
  3. Ensure the pipe ends are intact, smooth, and evenly colored.
  4. Verify that the pipe sizes and quantities meet the requirements.
  5. Ensure the pipe wall thickness and roundness meet the installation’s water tightness requirements.
  6. Avoid excessively thin pipe walls to prevent compromising pressure resistance and causing cracking.
  7. Pay attention to deviations in pipe material sizes to avoid affecting sealing and connection strength, thus preventing leakage issues.

Installation Process

The installation of PPR pipes involves utilizing a heat fusion connection method, and it allows for a single connection between pipes and fittings. Hence, accurate construction according to design requirements and specific site conditions is essential when installing supply water pipes inside walls. If pipes are buried underground, the number of joints in the underground portion should be minimized as much as possible. To prevent damage to pipes during secondary renovations, use colored paint to mark the pipe’s location on the walls or floors after installation. Additionally, proper installation of pipe supports according to specifications is crucial for PPR pipe installation.

Heat Fusion Connection Procedure

  1. Ensure the welding machine temperature reaches 260°C, confirm the light bulb is off, and clean the welding tool.
  2. Use pipe scissors to cut the pipe vertically along the axis.
  3. Insert the pipe into the dedicated welding tool. The tool is designed to prevent errors that operators may make.
  4. Connect only ERA fittings to their corresponding pipes. Follow the guidelines for systems installed with ERA fittings.
  5. When hearing sound and material coming from the small hole at the end of the ERA welding tool, remove the pipe and fitting from the tool.
  6. Immediately connect the pipe and fitting removed from the welding tool without wasting time. Do not twist the pipe and fitting.
  7. Strictly follow the operational issues mentioned in the Era Coal Machine Group product catalog and manual.


  • If the operating environment temperature is below 5°C, the heating time should be extended by 50%.
  • Before stabilizing the welded pipe, remove the aluminum cap to adapt to the welding depth.

Important Note: Before operation, ensure your welding machine is in good working condition.


PPR piping systems are favored for their easy installation, long service life, corrosion resistance, and resistance to scaling. Therefore, proper preparation is essential before installing PPR pipes, and the heat fusion connection procedure must be strictly followed to ensure the quality and effectiveness of the piping system. After installation, correct placement of pipe supports and using colored paint to mark pipe locations are necessary. In summary, proper installation of PPR pipes is key to ensuring their stable operation and prolonging their service life.
