Plumbing System

The flanges and flanged connections to date are very important for valves, pipelines, plumbing systems and water pipes. Wide range of flanges and flanged compounds due to the versatility of these parts, pipes and pipe flange connections armatury.Eta versatility has some justification. The first is the material of manufacture flanges and flanged compounds, characteristics of the steels used for manufacturing these parts, pipes are very different, they operate in temperature ranges from -70 to +800 degrees Celsius, have different characteristics of hardness, plastic viscosity, impact strength. The use of different grades of steel considerably broadens the scope of the flanges and flanges, pipe components can be used under various climatic conditions (from south to the far north regions) and with different working fluids (water from reactive to acids). The ability to use geometric parameters of the flanges and regulated by the State Standards, the most often used: GOST 12821-80, GOST 12820-80, GOST 28759.3-90. Those standards govern the use of flanges and flanged joints with a diameter of 15 mm. to a maximum diameter of 4000 mm.

and working pressures from 1 atmosphere to 200 atmospheres. Application flanged connections, is in a very wide range, from home systems to heat and water-route of pipelines. To date, these pipe components used in virtually all areas of industry and agriculture, is a very responsible piece of almost every element of the pipeline, as all the piping work under pressure, at least several atmospheres. These requirements to flanges and flanged connections led to a multi-level quality: input and output control of the chemical composition of steels used, control of micro-and macro-steel, heat treatment and control Finally control of geometrical parameters. In this article, we described the significance of flanges and hopefully helped you learn something new about the details of piping.
