During the construction of modern housing it is impossible to do without the device of pipeline systems. Through the pipeline in the house, water, gas, heat, and sewer drains are outlined from the house. For high-quality work of the pipeline, water flow control or gas flowing through it, branching devices or taps, pipeline fittings are needed. To your pipeline function without problems, it is necessary to deal with the characteristics and purpose of these devices.

What do you need pipe fittings?

When the pipeline device, you have to equip taps, bends, compounds, adjust the pressure, mix liquid or gases in the pipe, for this use pipeline fittings - a special type of connecting and adjusting products for the pipeline.

The scope of reinforcement is different, therefore distinguish such types:

• shut-off pipe fittings - used when it is necessary to overlap the current of the liquid or gas in the pipe, for example, a valve or damper;
• regulatory reinforcement - subspecies of shut-off reinforcement, employee for regulation (reduction or increase) volumes of fluid flow or gas in a pipe, for example, valve or crane;
• safety reinforcement - Used to reset excess steam or water in case the pressure in the pipe exceeds the allowable value. Serves to protect pipes, such devices include safety valves;
• distribution-mixing fittings are taps, adapters, tees used to distribute streams through pipes and mixers for mixing flows, for example, bathroom faucets or kitchen;
• condencathor - designed to remove the resulting condensate and superheated steam.

Characteristics of pipe fittings

On the modern market for pipelines, a huge number of domestic and foreign manufacturers, as well as the range of pipelines for pipelines, characterized by functionality and characteristics are presented. So if there is a pipe fittings when building a pipeline, it will not buy it difficult.

So that pipe fittings served a long time and reliably, it is necessary to respond with its choice, clarify the load with which your pipeline and its parts will work. The selection of reinforcement depends on the parameters that determine the technical characteristics of the devices.

The main parameters for which the pipe fittings are selected, this is:

• the diameter of the conditional passage of the pipe (labeled DN), or, in other words, the inner diameter. This value determines the bandwidth of the pipe or reinforcement;
• the conditional pressure (marked PN) is an indicator of the maximum possible pressure at which the reinforcement is operating under normal mode for a long time, calculated at a temperature of 20 ° C;
• working pressure - calculated at normal temperature of the conducted medium and denotes the largest redundant pressure value at which the reinforcement works in a given mode for a long time;
• the calculated pressure is the predicted pressure, expected when exposed to the minimum or maximum temperature;
• temperature mode - the received operating temperature, in which the valve and the pipeline itself will be operated;
• the capacity of the pipeline is a characteristic that determines the cross section of the reinforcement;
• the gate tightness step affects the choice of material from which the reinforcement is manufactured;
• environmental parameters.

All of the above characteristics are important for the successful selection of pipe fittings and the functioning of the pipeline. If the technical characteristics of the pipeline are known, its purpose, alleged loads, the use mode, then choose the necessary pipe fittings to it are not difficult.

Types of pipeline fittings

Pipelines are constructed for transportation of various substances - steam, water, oil, sewer, ventilation. Naturally, pipeline fittings for each kind of their own.

The material from which the cabinet parts are made can also be different. Accordingly, the valve happens:

• steel pipe fittings - material serves carbon and alloy steel;
• corrosion resistant reinforcement;
• armature from gray, forged or high-strength cast iron;
• non-metallic fittings - based on polyvinyl chloride, viniplast or other polymeric materials;
• ceramic fittings;
• glass fittings.

The choice of material of pipe fittings depends on the purpose, the parameters of the use of the pipeline. For example, fittings made of gray and forging cast iron cannot be used if it is subjected to sharp temperature differences or vibrational effects.

Pipe fittings and scope diffuses.

In industrial production, with a device of water pipelines, heating systems, steam pipelines, tubing fittings of general construction purposes are used. Usually this is a serial production fittings (valves, shut-off valves, pressure valves, regulating valves, condensate) of well-known enterprises that have proven themselves. The market presents a variety of pipe fittings, the price of which depends on the quality and firmware of the manufacturer. For example, Zetkama, Polix, Ari-Armaturen are known from foreign brands producing fittings.

Industrial reinforcement for use in special conditions of work is used in pipelines that will be operated at low or high temperatures at high pressure using corrosive substances, toxic and radioactive liquids.

Plumbing reinforcement is used in the device of household pipelines - gas laying to the household gas stove, water supply and equipment of bathrooms by mixers, shower plants. For these works, ball valves, valves, pressure regulators, check valves, filters are used.

There are also pipeline fittings for special purpose, which is used in the conditions of special technical requirements, for example, in experimental installations and is usually made on special orders.

If you figured out the appointment of the pipeline, and, accordingly, acquired reinforcement, think about the issue of joining the pipeline. Depending on the accumulation option, such types are allocated:

• flange pipe fittings, for joining which flanges are used to the pipeline;
• armature coupling - connecting fittings with internal thread, is usually used with a value of a conditional passage of not more than 40 mm and when using a pipeline for neutral and non-combustible substances;
• handic reinforcement - applies under the same conditions as coupling fittings;
• equipment fittings - fittings and fittings, which are used for devices of turns, branches, transitions to another diameter in pipelines;
• welded fittings - used in the device of steel pipelines and pipelines from plastic materials and ceramics. Often, the need to apply this type of connection is caused by the risk of the conducted medium through the pipeline, and the welded joints exclude the possibility of seeping.

The choice of pipe fittings also affects the need to use regulation, it can be manual or automatic. Depending on this parameter, the controlled and autonomous fittings are isolated. The controlled reinforcement is equipped with a manual drive, or, depending on the design, the drive can be mechanical, electrical, hydraulic, electromagnetic.

In order for pipeline fittings to function for a long time and safely, when selecting it is necessary to be guided by its functional purpose. Naturally, the buyer, choosing reinforcement, looks not only on the technical characteristics, but also on its cost, durability, simplicity and availability of use and maintenance. Among the product reinforcement produced today, you can choose devices that meet all the requirements.

The pipeline products and pipeline fittings have currently become the most popular products from the metal, and in the context of construction growth there are all chances for increasing its production and sales.
