PP-R pipes

PP-R pipes

PPR pipes are very popular because of their special features such as heat resistance and high-pressure resistance, being non-corrosive even in chemical environments with high pH; no leakage, no noise, abrasion resistance, no toxicity, being hygienic. Especially, due to their low thermal conductivity and electrical conductivity, they are thought to be safe and fuel-efficient for hot water systems.

- Standard: DIN 8077/ 8078:2008; BS EN ISO 15874-2:2013.

- Color: Green or white-blue stripes, Green or white red stripes. The pipe for cold water is marked with blue stripes. The pipe for hot water is marked with red stripes.

- Joint: Joining pipe and socket joint fittings by socket fusion joint, Thread joint.


- High-Temperature Resistance: The sustained working temperature is up to 95oC, the maximum transient temperature is up to 135oC.

- Heat Preservation: low thermal conductivity result in preserving heat.

- Non-toxic: no heavy metal additives would net be covered with dirt or contaminated by bacterium.

- Low Installation Costs: lightweight and ease of installation can reduce installation costs.

- High Flow Capacity: smooth interior walls result in low-pressure loss and high volume.

Prepare Preparation: Pipe and jointing fittings; pipe cutters, specialized cutting tools, welding machine

1. Cut the pipe

Cut the pipe perpendicular to the cutter or specialized cutting tools

2. Clean pipe ends and join fittings

3. Mark

Mark, the depth to join the pipe and jointing fittings

4. Take the pipe and fittings

When the red light switches off, the heating is up to 2600, take the pipe and fittings to the welding end

5. Join the joining parts together

Hold the pipe and fittings in position for several seconds and then pull out the pipe and fittings. Join the joining parts together. Keep the pipe firmly in place after jointing.
