Threaded radiator: recommendations for the choice of
In the process of assembling the heating system, many of the most diverse components are used, and some of the most common and sought-after ones are futorki, with their help the radiator is attached to the pipelines, so special requirements are made to this group of components.
Consider what products are used during the work and how the assembly process should be organized in order to achieve the best result and durability of all the joints obtained.
Recommendations on the selection of components
To begin with, we will look at what criteria should be paid attention to when choosing components for assembling a heating system; these recommendations will concern not only the fittings, but also all other necessary elements:
| Match by size | If you do not know the parameters of the equipment, then it is unlikely that you will be able to purchase components, as a last resort, if you decide to do the work yourself for the first time - capture the documentation for radiators and other equipment included in the system so that the seller can figure out what you need |
| Availability of a heating system plan | This is much more important than you think, so you need to make a sketch, perfect accuracy is not required of you. The main thing - a clear definition of the location of all nodes in the system and the features of their location relative to each other. This will greatly help in determining the exact number of those or other components, you will not miss the important nuances |
| Thread matching | Another important factor, as the type of connection and its step may differ. Moreover, the differences can be both in the measurement system (inch or metric), and in the thread pitch. Of course, most manufacturers try to manufacture products according to certain standards, but nevertheless some features still occur, and it is important to know about them in advance (again, the instructions attached to the equipment will help) |
| Quality of products | To determine how solidly this or that product is executed is possible by eye - the thread inside and outside should be smooth without flaws and damage, other surfaces should be smooth and well-treated. If we are talking about components for aluminum and bimetallic radiators, then the products are most often painted white, since most radiators have exactly this color |
| Manufacturing material | A cast iron radiator casing should be made of the same material as the main element, as for bimetallic and aluminum radiators, galvanized steel products are the best solution for them, they are quite reliable and durable, while their price is democratic |
| Check items | It is best to check how well the element is wound on the thread, if you get a lot of units, then check at least a few of them to choose from. Parts should be wound easily enough without any effort on your part. If resistance is felt, then the thread on one of the elements is damaged. |
Tip! We recommend purchasing components from the same company as the main components. In general, the easiest way to buy everything you need in one store, then the experts will complete the whole set for you, and you will save a lot of time, since you will not have to figure everything out by yourself, they will explain everything right on the spot.
Features of the considered type of products and recommendations for the work
We will analyze in detail the design and purpose of the futorka and will describe how to properly install it during the installation of radiators in the heating system.
What is futorka
Consider the features of this type of product, first of all, the scientific definition is voiced: a ferrule is a special adapter that has an internal and external thread, and the diameter of the external thread is always larger than the internal one.
As an example, we give a version of the product? on?, such marking means that we have an adapter with a diameter of internal thread in? and the outer diameter - 3/4, everything is quite simple and clear.
If we consider this group of products, we can easily notice that it is divided into two large groups: futorki for cast iron radiators and adapters for bimetallic and aluminum products. Consider each of the options in more detail and in detail.
Nodes for cast iron radiators
Products intended for use on cast iron radiators have the following features:
- Adapters are specifically designed to connect cast iron batteries to pipelines or valves (depending on the design of the heating system).
- The most common variants cast in cast iron., they have no outer coating, so their cost is very low, this option can rightly be considered the most budget, while its reliability is very, very high.
- Brass products can also be used for work., but they are much more expensive than the first option, moreover, in the process of using brass, it tends to stick tightly to the cast iron, and it will be almost impossible to remove such a connection. That is why this solution is less popular among specialists.
- Remember that depending on which side of the radiator the connection will be made, the element may have both right and left threads. It is better to check the direction of twisting in advance in order to know exactly how many and what elements will be required in the process.
- The design of the adapters is such that they can be clamped using a variety of devices. - open-end wrench, spanner wrench, plumbing key. It all depends on what you have on hand, the result will be excellent anyway.
Tip! It should not be used to seal the thread on the futorka FUM tape, as it does not tolerate high temperatures, it is better to use the classic version with flax or modern sealing compounds.
- Products correspond to the following characteristics: The maximum pressure in the system is up to 25 Bar, the maximum temperature is 300 degrees, adapters are suitable for working with environments such as steam, water, gas, oil, air and special heat transfer media.
Adapters for aluminum and bimetal
This group of products is used quite often and has differences from the above described option:
- The material of manufacture is often high-strength galvanized steel., resistant to corrosion processes and ensuring high reliability of all compounds.
- In order for the element to look more attractive and to be protected even more reliably, it is covered with epoxy powder enamel on the outside., which is characterized by high strength and resistance to deformation effects.
- Depending on the location side, there are variants with right and left threads., you choose which ones and how many are needed.
- In order not to damage the surface of the product when twisting, it is recommended to use a special wrench., which is most often made of plastic. It can be used to tighten the connection with high quality, while the metal surface will not be damaged, and you will not tighten the connection too much, as the plastic will simply break.
- Product features are as follows.: The working pressure should not exceed 16 bar, and the maximum coolant temperature in the system should not rise above 110 degrees for a long time.
- Regarding seals, paronitic or silicone rings are most often used., they retain their elasticity for a long time and are resistant to high temperatures.
- For the convenience of customers sold ready-made kits, which includes 4 futorki and 4 gaskets, one plug and one Mayevsky crane, as well as a key for work, it is very convenient.
Conclusion
The video in this article will tell even more about this product group, because adapters are an important part of the system. You will understand the topic even better.
