What to do if there is trachoma in the heating pipe
During winter heating, trachoma (tiny leaks) in heating pipes is a common problem. If not dealt with in time, it may lead to water leakage, corrosion or even pipe bursting. The following is a summary of solutions to heating pipe trachoma that have been hot topics on the Internet in the past 10 days. It combines professional advice and user experience to provide you with a structured guide.
1. Causes and hazards of trachoma
| Cause classification | Specific performance | Hazard level |
|---|---|---|
| Material aging | The pipeline has been used for more than 5 years and the inner wall is corroded. | ★★★ |
| water quality issues | High oxygen content or acid-base imbalance in the water | ★★☆ |
| pressure fluctuations | Heating system pressure suddenly increases | ★★☆ |
2. Comparison of emergency response plans
| method | Operation steps | duration | cost |
|---|---|---|---|
| Rubber pad + pipe clamp | 1. Close the valve 2. Wrap the rubber pad 3. Tighten the pipe clamp | 1-2 years | 20-50 yuan |
| Epoxy resin glue | 1. Polish the leaking spots 2. Apply AB glue 3. Curing for 24 hours | 3-5 years | 30-80 yuan |
| Cold welding technology | Fill with metal repair compound | More than 5 years | 100-300 yuan |
3. Professional maintenance process
1.Detect positioning: Wipe the pipe with a dry paper towel and observe the wet spots to determine the location of trachoma
2.System drainage: Close the entrance valve and open the lowest drain valve
3.repair operation:
• Diameter ≤ 2mm: Use thread sealant + glass fiber tape wrapping
• Diameter >2mm: The pipe section needs to be cut and replaced. It is recommended to use hot melt connection.
4.stress test: After repair, pressurize to 1.5 times the working pressure and keep the pressure for 30 minutes.
4. Preventive measures are hotly discussed across the Internet
| measures | Implementation frequency | effectiveness |
|---|---|---|
| Add corrosion inhibitor | Before heating every year | Reduce corrosion rate by 60% |
| Install magnetic filter | One-time installation | Filters 90% of metal particles |
| Pipeline cathodic protection | every 3-5 years | Extend life by 8-10 years |
5. Answers to users’ high-frequency questions
Q: Will water leakage from trachoma affect the heating effect?
A: A single trachoma has a small impact (the water temperature decreases by about 1-2°C), but multiple leaks will cause the system pressure to drop by more than 20%.
Q: How to deal with trachoma temporarily when it is discovered at night?
A: You can first use a bicycle inner tube + iron wire to tie it up, and report it for repair immediately the next day. Note: Ordinary tape is prohibited as it will easily fall off due to high temperatures.
6. Maintenance cost reference
| Maintenance method | Material fee | Labor cost | Warranty period |
|---|---|---|---|
| emergency patch | 50-100 yuan | 100-200 yuan | 6 months |
| Pipe segment replacement | 150-400 yuan | 300-500 yuan | 2 years |
| Whole house renovation | Starting from 2,000 yuan | 80 yuan/meter | 5 years |
Warm reminder:According to the "Heating Management Measures", the pipelines behind the household valves are within the scope of the owner's self-maintenance. It is recommended to conduct professional inspections before heating every year. In old communities (houses over 15 years old), priority should be given to the overall replacement of PPR pipes.
