As the weather becomes colder and colder now, many homes will install heating equipment when they are installed at home. If the heating pipe leaks, it will affect the heat supply and even endanger the safety of the user's property and life. Therefore, the cause of the leakage of the heating pipe should be analyzed in a timely manner and corresponding countermeasures should be taken. Here we introduce: heating pipeline leak repair program and how to choose a heating pipe.
The reason for the leakage of the heating pipe and maintenance program:
A: Water leakage at the connection of the heating pipe
Before the community presses the test water, all the water injected into the pipeline is generally cold water. The principle of thermal expansion and contraction will lead to leakage of the heating pipe joints. In general, the water pressure will not be too large. The user can use a towel or a rag to pipe the water. Gently wrap around, leaving a section in the basin, let the water flow to the basin, and then find a professional repair, do not handle the maintenance on their own, once the improper operation, the disconnect will cause greater losses to you.
II: Shaker leakage of heating pipe
When there is water leakage from the heating pipe, you need to wrap the towel or rag around the pipe and leave a section of the water in the basin to bring the water to the basin. If you have a bike inner tube, you can cut it into a section about 1 cm wide and about 50 cm long. Pull the inner tube strip 3 cm away from the trachoma, and then squeeze it 3 cm over the trachoma. After 3 to 5 days, the trachoma will rust automatically.
Three: exhaust valve rupture leaking
Due to water injection pressure test, some pipes will enter the air, some users worry that this will affect the heating effect, self-tightening the exhaust valve deflate, but due to the finer internal connection of the exhaust valve, if the operation is not easy to break , causing leakage. At this point the user should not panic, you can find a round chopsticks, chopsticks as a wedge into the leak, and then ask a professional maintenance.
Heating pipe how to choose:
1. Heating pipe material, mainly aluminum plastic pipe, PPR pipe and PB pipe, aluminum plastic pipe insulation is good, the outer wall is not easy to be corroded, the inner wall is smooth, so that the resistance to water flow is small, and can be bent freely, it is convenient to construct, while the cost It is also relatively high. PPR pipe corrosion resistance, heat resistance, light weight, high mechanical strength, easy scaling, long service life. And now there are PPR aluminum plastic pipes on the market, which combine the advantages of PPR pipe and aluminum plastic pipe.
PB tube is a kind of polymer inert polymer, has high temperature resistance, durability, chemical stability, plasticity, tasteless, odorless, non-toxic, non-fouling, long life and other characteristics, but the PB tube oxygen permeability comparison High, need to block oxygen. At present, all oxygen blocking PB pipes are on the market.
2. The length of heating pipe and the choice of pipe diameter must be chosen according to the actual situation. Generally, the finer the pipe diameter and the longer the pipe, the greater the resistance and the lower the flow rate.
3. The installation of heating pipes adopts a single-tube series connection, which connects the pipes, radiators and boilers in series. If there is a local failure, the entire system cannot work and the heating pipes are required to be thick.
4. The installation of heating pipes adopts a double-pipe parallel connection method. Each radiator can be controlled individually. The balance of water flow is higher than the previous one, requiring a short pipe run.
5. The installation of heating pipes adopts the double-pipe parallel connection method. The water flow in each set of radiators is basically the same, and the balance of the water flow in the entire system is the best, which saves heating costs and facilitates maintenance.
Editor's summary: Heating pipe leakage repair program and how to choose a heating pipe are introduced here. Hope to help you, more information, please pay attention to this site.
