What we can imagine finding in a newspaper or online ad such as "buy stop valves"? Surely everyone in the head just pops up the image of steel rods, which freezes the mixture of sand, cement and water, forming concrete. Indeed, the metal bars – this is also fitting (as, for example, a sculpture for the spoils of war art), but in this case, the advertiser is interested Pipeline fittings. So what is it? By definition, this auxiliary parts and equipment, without which any pipe will remain just a piece of metal that would not go for it – the black gold, natural gas, or water. More precisely, it is valves allow something to go, move along the pipe. With the help of various devices flow of chemicals called in this case, the working environment, it becomes manageable – you can adjust its power pressure inside the tube, movement, direction and other parameters. So, stop valves stop the flow, adjusting, you guessed it regulates distribution sends it to the right place. Some species only fitting to their destinations account for more than a dozen. Market valves is booming – and this process has a lot to say about the economy as a whole. In fact, no one working on the pipe the light is not without relevant devices and pipes are used in so many areas of our lives that it is impossible to enumerate. The demand for pipe fittings grows when construction becomes more intense. At this size, architectural features and purpose of buildings have no value – communication, they still required, no capital residential, industrial or public building is not without piping systems. New pipelines will require a huge amount of detail to ensure their smooth operation. These elements are necessary and the gasification of rural areas. Therefore, increasing not only the rent tubes and fittings production. A leading position in the industry, including Russia, staffed by the largest enterprises – in Chelyabinsk, Yekaterinburg, Shchelkovo and many other places. Finally, valves as well as everything in our world is becoming more high tech. During its production, as in the pipes, use new materials – not only traditional metals and alloys, but plastic, plastic, asbestos. Control devices are perfect, the automated control system. In short, the market for valves can be likened to an iceberg – we have a general idea of what it is, but the bulk of hidden from our eyes.
