What is metal fittings for plastic sewer pipes
To put it more clearly, the metal fitting is an element through which the configuration of a network of pipes is realized. Thanks to him, the specialist makes the necessary forkings and bends. In this case, distinguish two types of fittings:
- straight( connect a pipeline of the same diameter);
- transitional( connect a pipeline of different diameters);
- As you can see, they allow to reduce or increase the diameter of the plastic pipe in the right place. In addition, with their help it is possible to provide:
- pipe connection in two directions;
- bending of the pipe at different angles;
Especially popular is the fitting for polyethylene pipes for welding. It is placed on the pipe and heated with a soldering iron joint place, which in the end, is not inferior to solid casting in strength. One negative - this fitting can not be used again.
Compression fittings as one of the ways of connecting plastic heating pipes.
The main advantage of this product is that special tools are not needed for installation. To establish it correctly and qualitatively, it is enough to apply the power of hands.
In appearance, these are two usual clamping nuts and rubber gaskets clad on the body. Nuts must be screwed onto the ends of the pipe with threaded threads. This is quite simple, because basically they have hooks or a relief surface, so that the product does not slip even when twisting with wet hands. Rubber gasket, when tightened tight, does not allow leaks at the connection point.
The construction connected in this way is easily dismantled. Most often, it is used for surface gaskets of the pipeline( for example, in the country), in which case the system can be disassembled and hidden.
Press fittings and brief information about them
When installing them, the minimum number of equipment is used. It looks like a product like a casing with gaskets and two sleeves, which are pressed into the ends of the connected plastic pipes.
Pressing itself is carried out with the help of special pressing pliers with which the sleeves are inserted. If you do not make the most of this process, expect leakage.
This type of product has an antistatic ring, which means that if the potential difference between the two materials is different, the charge will not accumulate. The advantages include a simple installation without the use of electricity, as well as high strength of the connection.
If you need to disassemble the pipeline, use the press clamp again, but when reinstalling, mount each removed fitting exactly in its place( for this, it's better to immediately number each product).
strong connection with
electric-welded fittings This type of product provides the most reliable connection. This is a case, with built-in copper heaters, each of which has an outlet under the electric heater. Uniform heating provides the supply of electric current to the outputs. As a result, a continuous and qualitative weld will be obtained.
Let's list the main advantages of this connection:
- when reheating, the pipeline is easy to separate;
- high reliability, as a single-piece design;
- high installation speed;
- installation can be carried out remotely, i.e. To a place difficult to reach by hands;
- quick repair;
- welding process is permissible in automatic mode;The
- can be recognized by a barcode on the body.
Brass fittings as an alternative connection
Most often, this type of product is mounted on the threaded connections. It is more durable than a plastic sample. Brass is also sometimes used in press fittings.
The variety of this product allows the installation of the most unusual design. Brass fittings have a number of advantages:
- is used to extend the pipeline;
- there is the possibility of installing the structure in a stretch;
- brass, covered with platinum, is inert to cold and hot water;
- construction can be cleaned with acid, since brass is not affected by its effect;
- this type of product is used for a pipeline exposed to vibrations( for example, it is ideal for new buildings).
This is an element that works by tightening a ring made of soft material, when twisting the crimping nuts. As a material for manufacturing use plastic or brass. At installation it is not required mass of the equipment, it is enough to apply force of hands and to have in reserve two spanners. If a pipe break occurs, it is the crimping fitting that will cope with this problem best, regardless of what material the pipeline is made of.
