How to connect PERT EVOH Pipe to solar water heaters?
Leave a message
Connecting PERT EVOH pipes to solar water heaters is a crucial step in ensuring an efficient and long - lasting solar water heating system. As a supplier of high - quality PERT EVOH pipes, I am well - versed in the process and excited to share the necessary knowledge with you.
Understanding PERT EVOH Pipes
PERT EVOH pipes are a type of cross - linked polyethylene pipes with an ethylene - vinyl alcohol (EVOH) layer. The EVOH layer acts as an oxygen barrier, preventing oxygen from diffusing into the heating system. This is essential as oxygen can cause corrosion in metal components of the solar water heating system, such as pipes, valves, and heat exchangers, reducing their lifespan.
We offer two main types of PERT EVOH pipes: PERT/EVOH Pipe 5 Layers and PERT/EVOH Pipe 3 Layers. The 5 - layer pipes generally provide better oxygen barrier performance and mechanical strength, while the 3 - layer pipes are more cost - effective for less demanding applications.
Pre - installation Preparations
Before connecting PERT EVOH pipes to a solar water heater, several preparations need to be made:
1. System Design
First, design the layout of the piping system. Consider factors such as the location of the solar panels, the position of the water heater, and the overall flow path of the water. The pipes should be routed in a way that minimizes bends and reduces pressure losses. Use appropriate software or consult with a professional if you are unsure about the design.
2. Material Selection
Select the appropriate size and type of PERT EVOH pipes based on the flow rate requirements of the solar water heating system. Larger diameter pipes are generally used for higher flow rates. Also, ensure that you have all the necessary fittings, such as elbows, tees, and couplings, made of compatible materials.
3. Safety Equipment
Gather safety equipment, including safety glasses, gloves, and a dust mask. This will protect you from potential hazards during the installation process, such as sharp edges on pipes and fittings and dust generated during cutting.
Installation Steps
1. Cutting the Pipes
Use a sharp pipe cutter to cut the PERT EVOH pipes to the required lengths. Make sure the cuts are clean and perpendicular to the pipe axis. After cutting, remove any burrs or debris from the cut ends using a deburring tool.
2. Preparing the Fittings
Clean the inside of the fittings and the outside of the pipe ends. Apply a small amount of pipe lubricant to the pipe ends and the inside of the fittings. This will make it easier to insert the pipes into the fittings and ensure a proper seal.
3. Connecting the Pipes
Insert the pipe ends into the fittings firmly. For solvent - welded fittings, apply the solvent cement evenly to both the pipe end and the inside of the fitting, then quickly insert the pipe into the fitting and hold it in place for a few seconds until the cement sets. For compression fittings, tighten the compression nut using a wrench to create a tight seal.
4. Installing the Pipes
Once the pipes and fittings are connected, install the piping system according to the pre - designed layout. Secure the pipes using pipe clips or hangers at regular intervals to prevent movement and vibration.
5. Connecting to the Solar Water Heater
Connect the PERT EVOH pipes to the inlet and outlet ports of the solar water heater. Use appropriate adapters if necessary. Make sure the connections are tight and leak - free.


Testing the System
After the installation is complete, it is essential to test the system for leaks. Fill the system with water and pressurize it to the recommended operating pressure. Check all the connections for any signs of leakage. If a leak is found, immediately shut off the water supply and repair the connection.
Maintenance and Troubleshooting
Regular maintenance of the PERT EVOH pipes and the solar water heating system is crucial for its long - term performance. Inspect the pipes and connections periodically for any signs of damage, such as cracks or leaks. Replace any damaged components promptly.
If you encounter problems such as low water flow or high pressure in the system, check for blockages in the pipes or fittings. Also, ensure that the solar panels are functioning properly and that the water heater is operating at the correct temperature.
