Choosing fittings for installation of pipes for heating systems, gas pipelines and water supply? Review + Video

Choosing fittings for installation of pipes for heating systems, gas pipelines and water supply? Review + Video A fitting is a part whose main task is to connect pipes together. In addition, it is used to make the transition to a larger or smaller pipe diameter or branching.

Nowadays, the American fitting is used in many areas, from industrial to municipal. This detail is simply irreplaceable in cases where there is a need to change the direction of the highway or finish it.

Various materials are used for the manufacture of a fitting: steel, brass, polymers (polyethylene, polypropylene).

To choose the best option, take into account what material the pipes are made from in your house.

There are various types of connection for mounting a fitting: welded, threaded, flanged, and so on.

Modern home comfort

In water supply systems

Heating and water supply systems are one of the most important in our houses. Now no one from the residents of apartment buildings, and even private ones, can even imagine how it is to take buckets and go down to fetch water to a water pump or a well, and it is better to keep silent about the toilets on the street. Comfort comes first in the modern world.

And in order to create it, we need all the vital communication systems in our home, which in particular consist of various parts.

The main requirements for the pipeline are high-quality materials, strength of the connection and long service life. To achieve this goal, good pipe and fittings material must be used. The fitting is just that element of the system, which you cannot do without.

Types of fitting

The modern market offers a wide selection of various types, forms of fitting, depending on the purpose:

  • Choosing fittings for installation of pipes for heating systems, gas pipelines and water supply? Review + Video Adapter ;
  • Fitting.

  • Coupling ;
  • Plug ;
  • Tee.

Depending on the place of use, the fitting is divided into intermediate and connecting. In the case of connecting pipes of the same size, straight joints are required.

If the pipes are different, adapters will be required, which are produced with a threaded connection designed to connect pipes from different materials. Metal and plastic pipes are connected using an adapter, which is equipped with a nickel-plated brass insert.

It is necessary to tighten the connection using a tightening wrench.

Depending on the connection method, these elements are subdivided into:

  • Compression fittings - equipped with a special ring for sealing, which ensures a tight connection of pipes.
  • Push fittings are used for all types of pipes.
  • Compression pipe fittings are easy to install and have some popularity.
  • Threaded fittings are the oldest pipe connection method, which is threaded on the outside.

    They must be wound onto the pipe.

  • Press fittings for multilayer pipes.

Let's take a closer look at push-fittings, which have a lot of positive characteristics. Their advantages are as follows:

  • Environmentally friendly.
  • Easy to install.

  • No need for special tools.
  • Maintenance-free during operation;
  • Ease of installation in hard-to-reach places.

Classification of elements for connecting pipes depending on the material of manufacture:

  • Choosing fittings for installation of pipes for heating systems, gas pipelines and water supply? Review + Video Cast iron fitting.
  • Steel fitting.
  • Brass pipe fitting.

  • Bronze fitting.
  • Plastic fitting
  • Metal-plastic fitting.
  • Copper fitting.

Note.

  • Push-fittings are an innovative solution offered by the building materials market.

    It gained its popularity due to its versatility of use.

  • Bronze fitting is considered to be the best connecting element. It is made of a pure, highly environmentally friendly alloy that has anti-corrosion properties and is used in gas and water systems.
  • Brass fitting is often used as a connecting element in plumbing and heating systems. The parts have a special rust-resistant coating.

  • Chrome plated fitting excellent oxidation resistance.

Details of fittings

Fitting for plastic pipes

Most of the pipes on the modern construction market are polyethylene products. They are suitable for use in communication systems of residential and industrial complexes. In order to properly connect pipes with a fitting, it is necessary to select connecting elements. Depending on the purpose, fittings are: one-piece and split.

The detachable connection is made using a compression and compression fitting, steel flanges. The permanent PE connection is carried out by the method of connection and welding with a coupling. The use of welding involves the use of welded fittings (segment). This method is good for use when there is pipe branching.

Socket welding involves the use of electrofusion fittings.

This is a technology in which PE pipes are welded together. These elements do not lend themselves to rust, are resistant to the influence of chemical compounds, withstand shocks, and also have a long service life.

Fitting for polypropylene pipes

Polypropylene pipes have replaced the construction of their steel and cast iron heating and water supply systems. They have a number of indisputable advantages - they are easy to install and are cheap.

Advantages of polypropylene pipes:

  • Resistance to chemicals.

  • Easy to install.
  • Boiling water resistance.
  • Durability and reliability.
  • Ecological cleanliness.

This type of pipe is connected using a compression fitting and diffusion welding.

Other types of fittings

Compression fitting allows you to connect pipes together without using a welding machine. Installation is done using ferrules and rubber seals. This ensures a high level of tightness.

Choosing fittings for installation of pipes for heating systems, gas pipelines and water supply? Review + Video Cast iron fitting is made by casting and is used for gas and water supply systems. Cast iron products are manufactured based on GOST standards and have excellent performance characteristics, reliability and a long service life.

Cast iron elements are required for the reliability of pipe connections, making turns and transitions. Cast iron is still used in heating systems, gas utilities, and household appliances. The method of joining cast iron elements is socket and socketless. In order to increase the service life, galvanized cast iron assemblies are used.

Fittings for drainage and irrigation systems

The drainage system is used to remove excess moisture in the soil.

This allows you to protect basements and basements of houses from moisture penetration, and also protects plants from rot.

PVC pipes are used for the construction of the drainage system, which have a number of advantages:

  • Light weight.
  • Easy to install.
  • Resistance to aggressive environment.
  • Long term of use.

To install this system, use a special fitting for drain pipes. The system is mounted using adapters, couplings and tees.

For the system of drip irrigation of plants, thin tubes with a dropper inside are used. This is the most commonly used method. To install the tape, specially designed fittings are used.

The drip system has the following advantages:

  • Economical water consumption.
  • Plants are fed in dosage.
  • Watering is carried out at low water pressure.
  • Low watering time.

Summary of the article

Bottom line, there are specially designed connecting elements for each pipeline system.

Therefore, before starting the installation, it is necessary to study the features of each and select fittings based on the information received.
