A set of devices installed on pipelines, equipment that is designed to control flow, is called pipeline valves. The principle of operation of the reinforcement is based on changing (decreasing, increasing, overlapping) the cross-sectional area.
Where is it used?
The scope of application is very wide: urban networks of water, gas supply and steam disposal, gas, oil, chemical, metallurgical industry, energy, ports and many other industries. Pipeline fittings are also installed in internal engineering networks, condensate drainage and heating systems.
The most common types of pipeline fittings: valves, wedge and gate valves, gates, couplings and repair couplings, steam traps, clamps, valves, flanges, fittings, ball valves, hydrants.
Types of pipeline fittings
By functions performed:
- shut-off, to completely shut off the flow;
- trigger, for dumping working substances from tanks;
- regulating, to change the flow parameters;
- protective, for protection in emergency situations;
- distributor, to distribute the flow in different directions;
- safety, for automatic protection of pipelines in the event of a change in normal parameters.
According to the method of connection to pipelines, fittings can be: coupling, nipple, flanged or welded.
The materials from which the pipeline fittings are made must meet high requirements, because products are exposed to high operational loads. Modern fittings installed on pipelines are made of metals (cast iron, steel, aluminum) or polymers (PVC, vinyl plastic, polyethylene).
How to choose pipe fittings?
When choosing fittings for a pipeline, it is necessary to take into account its technical characteristics and operating conditions:
- working pressure;
- working temperature;
- bandwidth;
- resistance to aggressive media, corrosion;
- service life, response time;
- type of pipe connection;
- dimensions, weight.
When buying pipeline valves, it is important to choose a reliable and trusted manufacturer and supplier, because not only the functioning of the pipeline system, but also safety depends on the quality of the valves. High-quality pipeline fittings minimize the risk of emergencies, and their consequences can be greatly reduced.
