The need to disassemble radiators of heating occurs in cases where they began to leak, one of the ribs gave a crack or burst. In old buildings, when there was no question about energy saving, the radiators were mounted, in which the ribs were installed more than it is required, so unnecessary edges need to be removed.
Device radiator heating.
Before paving the heating radiators, regardless of their type, you should make sure that water is not supplied in the pipes. It is advisable to perform work together.
If the heating system is mounted on polypropylene or metal-plastic pipes, couplings are disassembled.
If the heating system is mounted from steel pipes, you need to try to promote Signs at the input and output of sections. If you fail, and so often happens in the apartments of the old building, the split must be cut off with a grinder or autogen.
It remains to remove the battery with the hooks, which it is attached to the wall, and put on a flat surface.
Disassembling iron radiators heating
The disassembly of pig-iron radiators sometimes becomes a very time-consuming process, but necessary.
Diagram of disassembly of cast-iron heating radiators: A - capture by nipples of the threads of sections by 2-3 threads of the thread; b - according to nipples and docking sections; in - connecting the third section; g - grouping of two radiators; 1 - section; 2 - nipple; 3 - gasket; 4 - short radiator key; 5 - Lomik; 6 - long radiator key.
The new or old radiator is placed on a flat place. At least on the one hand, it is necessary to remove ordinary funks or deaf - plugs. On different sections of radiators, they can be with the left or right thread. Usually cast-iron hoods have the right thread, the plugs are left. If there is no disassembly skills, and there is a free section, it is better to know before applying the force of which kind of this thread and in which direction the key should rotate. If the left thread, when disassembling cast-iron batteries, you need to rotate the key along the clockwise arrow.

As with the unscrewing of any nuts, you first need to "disrupt" the hoods from the place, i.e. Turn them on a quarter of turnover on both sides of the battery. Then the hoods are twisted so that the gap to several millimeters is formed between the sections. If you release the hoods more, the whole design will begin bending under its own weight and by the accompanying effort. At the same time, the thread can jam. That this does not happen, an assistant should be able to get an assistant to the disassembled battery that will hinder his weight.
Usually the disassembly of old heating radiators is hampered by the fact that the funki and sections "Cracked". In order to disassemble such a battery, you will have to apply autogen or soldering lamp. The connection site warms the circular movements. As soon as it is breaking enough, the hoods are twisted. If you failed to unscrew from the first time, the actions are repeated.
If there is not enough strength to disassemble the battery, you need to increase the key length. An ordinary pipe is used, which serves as Rachag.
Similarly, the embedded nipples are twisted for heavy radiators.
If it was not possible to disassemble the cast-iron battery with the considered methods, it remains to be cut into a grinder or autogen or split into a lying position of a sledgehammer. Smash or cut, you need carefully one section. After this operation, perhaps weens a clutch between sections, the battery will be able to disassemble the remaining sections to save.
The use of a "liquid key" or WD fluid does not give, since in old cast-iron batteries, the homethis were sealed with flax and paint, and the liquid will not fall on the thread.
Disassembly of aluminum heating radiators
Scheme of aluminum heating radiators.
Aluminum or bimetallic heating radiators are disassembled similarly to cast iron, but there are minor differences:
- it is smaller sizes of keys and nipples;
- As a rule, these are new products, so when they are disassembered, it is not necessary to apply such considerable efforts as in the case of cast-iron;
- On the front side of the plugs and hoods, there are syntheasses S and D, respectively, for the left and right thread.

Between sections for sealing metal gaskets are installed. After disassembly, they should wipe, clean and save for subsequent assembly.
Under the plugs, the gasket is usually made of silicone, when assembling them cannot be used and must be replaced with new ones.
Many models of aluminum sections are intimidable. You can disassemble them, but it will not be possible to collect.
For disassembly, you will need tools and materials:
- keys for disassembly (5/4 inches - for cast iron batteries, 1 inch - for aluminum or bimetallic);
- gas key;
- adjustable (sanitary) key number 2-3;
- Bulgarian with a disc on metal;
- blowtorch;
- Gas cutter (autogen);
- A piece of steel pipe.
It is necessary to take into account that the described work is dirty and noisy. Therefore, it must be coordinated with the neighbors.
Using the following tips and recommendations and if there is a tool, disassemble and assemble the heating batteries with your own hands.
