Despite the widespread introduction of new technologies and innovative artificial materials, fabrication (construction) of pipelines for various purposes (for several reasons) is carried out using classical steel (metal) pipe. In most cases, docking at:
- Connect additional end of the pipe or branching.
- Vertical or horizontal change of direction of the strip network.
- the Occurrence of elevated internal stresses in the form of dynamic impact in the places of changing the direction of flow.
- the Deposition fractions (dirt, sand, particles of metal) the radius of curvature of the pipeline with the subsequent emergence of the accelerated processes of corrosive destruction of the metal.
- Taps for horizontal or vertical change of direction of the pipeline.
- Tees and crosses for connection or branching of the pipeline system.
Made of welded method. As a bonding (connecting) element is used as a so-called stainless weld fittings that have the same tube parameters according to the dimensions of the outer and inner diameter. The use of expensive stainless steel due to the following technical features of the laws of hydro-and gasdynamics:
Additionally, the stainless alloys are not as susceptible to temperature extremes and exposure to chemically active substances. Have high strength characteristics in comparison with carbon metals.
Principal fittings
the Use of fittings allows for the design and installation of piping systems with rather complicated geometry of the directions without any loss of integrity or reliability. The most common components used in the fittings of the following types:
the Classification is based on existing parameters GOST, DIN or SMS. For the welded connection by means of electric welding requires the use of special electrodes, of the respective steel grade.
