| Zhihu | 1,200+ items | Emergency treatment, welding repair |
| Douyin | 8 million+ views | DIY repair, water leakage video |
| Baidu Tieba | 450+ posts | Replacement recommendations, stress testing |
| little red book | 3,500+ notes | Beautiful restoration and corrosion prevention |
2. Common symptoms of radiator trachoma
According to feedback from netizens, trachoma problems usually manifest as:
1. Tiny water seepage points (diameter 1-3mm)
2. Rust spreads radially
3. Leakage becomes more obvious when the pressure drops
4. Frequently occurs at welded joints
3. Comparison of 6 practical repair solutions
| method | Applicable scenarios | duration | Cost |
|---|---|---|---|
| Epoxy resin glue | temporary emergency | 1-3 months | 20-50 yuan |
| Cold welding technology | small area trachoma | 2-5 years | 100-300 yuan |
| Argon arc welding repair | Larger holes | More than 5 years | 200-500 yuan |
| Replace single component chip | multiple trachoma | More than 10 years | 500-1500 yuan |
| Professional leak-stopping agent | hidden location | 3-8 years | 80-200 yuan |
| Rubber gasket | Seams | 1-2 years | 10-30 yuan |
4. Detailed repair steps (taking epoxy resin as an example)
1.close valve: First close the water inlet and return valve and drain the accumulated water.
2.surface treatment: Use sandpaper to polish the rust to reveal the true color of the metal.
3.Cleaning and disinfection: Wipe with alcohol to remove oil stains
4.Mix glue: Mix epoxy resin according to the instructions.
5.filling compaction: Use a scraper to press the colloid into the hole.
6.Curing and waiting: Keep away from water for 24 hours
5. Five key measures to prevent trachoma
1. Do a pressure test every year before heating (recommended 0.8MPa)
2. Water quality treatment: install a filter and keep the pH value at 7-8.5
3. Maintenance with full water during non-heating season to prevent oxidation
4. Avoid collision with sharp objects
5. It is recommended to replace old radiators (more than 8 years old) in advance
6. Professional advice
According to interview data from heating company technicians:
| Radiator type | average life span | Probability of trachoma |
|---|---|---|
| cast iron radiator | 15-20 years | 12.7% |
| Steel radiator | 10-15 years | 8.3% |
| Copper aluminum composite | 20-30 years | 2.1% |
Consider replacement rather than repair when:
• More than 3 trachoma appear on a single set of radiators
• Leakage occurs again within 2 months after repair
• Accompanied by extensive rust peeling
7. Cost reference (latest data in 2023)
| Services | first tier cities | Second and third tier cities |
|---|---|---|
| Door-to-door testing fee | 80-150 yuan | 50-100 yuan |
| Welding repair | 300-600 yuan | 200-400 yuan |
| Single group replacement | 800-2000 yuan | 600-1500 yuan |
| system flush | 200-400 yuan | 150-300 yuan |
Warm reminder: emergency maintenance costs may increase by 30% in winter, and it is recommended to complete the maintenance in autumn. Through the detailed guidance in this article, you can effectively deal with the problem of radiator trachoma and ensure a warm winter.
