How to connect floor heating pipe PERT: analysis and operation guide of hot topics on the Internet
As winter approaches, floor heating installation has become one of the hot topics on the Internet recently, especially the connection method of PERT floor heating pipes that has attracted much attention. This article will provide you with a detailed analysis of the connection technology of PERT floor heating pipes based on the hot spots on the entire network in the past 10 days, and provide structured data reference.
1. Summary of recent hot topics in floor heating installation
| Hot search keywords | search index | Main discussion platform |
|---|---|---|
| PERT floor heating pipe connection | 187,000 | Zhihu, Douyin, Bilibili |
| Floor heating pipe selection | 152,000 | Xiaohongshu, Baidu know |
| Precautions for floor heating construction | 124,000 | WeChat public account, Toutiao |
| PERT pipe hot melt technology | 98,000 | Professional decoration forum |
2. Detailed explanation of PERT floor heating pipe connection method
PERT (high-temperature-resistant polyethylene) floor heating pipes have become a mainstream choice due to their high-temperature resistance and creep resistance. Their connection methods are mainly divided into the following three types:
| Connection method | Applicable scenarios | Tool requirements | Operational points |
|---|---|---|---|
| Hot melt socket connection | main pipe connection | Special hot melt machine, pipe cutter | The temperature is controlled at 260±10℃, and the welding time is 3-5 seconds. |
| Mechanical clamping connection | Temporary maintenance hatch | Special clamping tool | It is necessary to use matching copper pipe fittings to ensure that the sealing ring is intact |
| Electrofusion connection | special location connection | Electric fusion welding machine | Strictly operate according to the parameters marked on the pipe fittings |
3. Comparison of PERT tube connection technical parameters
| Pipe diameter (mm) | Hot melt temperature(℃) | Heating time (seconds) | Cooling time (minutes) |
|---|---|---|---|
| 16 | 260 | 5 | 2 |
| 20 | 260 | 7 | 3 |
| 25 | 260 | 8 | 4 |
4. Solutions to common construction problems
According to recent feedback from decoration short video platforms, PERT pipe connections mainly have the following problems:
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| Interface leakage | Insufficient hot melt time/uneven tube opening cut | Re-cut and ensure the hot melt time meets the standard |
| Deformation of joints | Insufficient cooling time means pressure | Operate strictly according to the standard cooling time |
| Poor water flow | Hot melt causes pipe diameter shrinkage | Control the hot melt depth to not exceed 1/3 of the pipe wall |
5. Professional construction suggestions
1.Material selection: It is recommended to use the same brand of pipes and fittings to ensure material compatibility. Recent market research shows that mainstream PERT tube brands include: Rifeng, Weixing, Jinniu, etc.
2.Environmental requirements: The construction environment temperature should not be lower than 5℃ to avoid the increase in material brittleness affecting the connection quality.
3.Acceptance criteria: After completing the connection, a pressure test should be carried out. The test pressure should be 1.5 times the working pressure, and the pressure holding time should be no less than 30 minutes.
4.Later maintenance: It is recommended to operate at low temperature (not exceeding 45°C) in the first heating season to avoid stress concentration at the joints caused by thermal expansion and contraction of the material.
Through the above structured data and operation guide, I believe you have a comprehensive understanding of the connection method of PERT floor heating pipes. It is recommended that non-professionals contact a qualified construction team for operation to ensure the safety and reliability of the floor heating system.
