Diagnostics of leakage of cast-iron batteries
In many apartments and houses there are still bulky cast-iron radiators. They continue to perform their functions to this day. Many of them are already about 50 years old. That longevity is the main advantage of cast-iron batteries. But here comes to you an unexpected trouble, under the battery there was water.
In principle, it's hard not to see that the cast-iron battery is flowing, as the traces of water appear in the room, and the humidity level increases significantly. But all these signs are visible during the heating season. Therefore, the question arises as to reveal the place where the cast-iron battery is leaking when the heating is turned off.
Unfortunately, at home this is difficult to do. Cast iron radiators are very heavy in themselves, and to check them, you need to fill them with water and see where it comes from. There is another way - to immerse the radiator in a bath with water and see if there are bubbles.
The third method is almost unrealistic to carry out at home, as it is necessary to blow the battery with air under high pressure, after covering it with soap foam. Thus, it will be seen where the air goes. In addition, there will be a hiss in this place, and you can feel the flow with your hand.
Restoration of cast-iron batteries by means of
tools. From where the cast-iron battery leaks, how to repair it depends. If a small breakthrough is formed at the junction of the sections, then it can be corrected with the help of an ordinary clamp, which is sold in the market and in any construction shop. The clamp looks like a metal structure with two inner-rubberized plates, which are connected by two bolts to each other. Careful fixing is done with nuts tightened to the required density.
Rubber gasket is the main element for blocking leaks. By the way, clamps are of any size, so it will not be difficult to choose the right one.
There is one more method to carry out repair of cast-iron batteries at the junction of sections, if at hand there is no such clamp. You can apply a simple piece of rubber, cut out of an elastic medical harness or bicycle camera. The place of leaking should be wrapped in several layers of rubber. You can fix it by wire, wrapped on top.
The cast-iron battery is flowing - we use the chemistry
If the cast-iron battery has run out due to the formation of a small hole, it can be corrected by cold welding for radiators. Visually it is similar to children's plasticine in strips. It is necessary to cut a small piece and knead it with your hands to a uniform color and a homogeneous consistency. After that, the welding is clamped with extrusive movements to the place of leakage.
The following method can also be applied to the connection of sections. To do this, wind the seat with a bandage, which must first be impregnated with epoxy adhesive .After he grabs, the leakage will stop.
In addition to all of the above, you can buy a polymer or powder sealant, which at the same time can eliminate leakage. The principle of operation of such a composition consists in polymerization during contact with air. Such sealant withstands high temperature, does not evaporate and prevents leakage.
Restoration of cast-iron batteries by such methods is not long-term, it is still necessary to call professionals to repair the radiator. Because in some cases welding work can not be avoided. And there are times when it is necessary to replace the entire radiator with a new one.
