FEROPLAST (FK) shaped pieces are components (fittings) of various shapes and sizes that are used in the construction of the pipeline. FK fittings are made in welded construction of non-alloy steel and all external and internal surfaces are protected by plastic coating.
Advantages of construction: According to the type, connection flanges are flat flanges made of slabs with connecting measures in accordance with standard 1092-2 for flanges made of cast iron, according to the recommendations of EN 545. Depending on the desired shape of the fitting, standard pipe fittings (couplings) for welding (according to EN 10253) with the outside diameter and wall thickness that are selected according to standard EN 1092-1 (steel flanges) are used for the body, for the appropriate DN and PN. All welding is done in accordance with recognized technologies with the application of appropriate filler material. At the end of the process all the surfaces are protected by electrostatic powder coating procedure.
The dimensions and shapes of fittings FK match the appropriate fittings made of ductile cast iron according to EN 545. The Table 1 gives the overview of the basic shape and dimensions FEROPLAST fittings FK, which are part of regular production (basic version) as well as the symbols that can be seen in various pipeline drawings. When ordering, please specify the details given in Table 1 and the pressure PN (or PFA, or PMA).
Installation:connect with flange with standard connecting dimensions,
Nominal sizes:DN 40 … DN 2000 (see Table 1),
Nominal pressure:PN 10, PN 16, PN 25 and PN 40 (see testing table),
Temperature:according to working conditions of the pipeline,
Operating fluid:according to working conditions of the pipeline.
Testing: Before the surface protection, each fitting is finally tested by water with hydrostatic pressure PEA (PMA +5) according to nominal pressure PN in accordance with standard EN 545.
Materials: In the basic version, the complete fitting is made of carbon steel S235 and all surfaces are protected by electrostatic powder coating powder with a final layer thickness of at least 250 microns.
On demand: Fittings FK can be entirely made of other material and with flanges according to other standards. Basic measures may be different from the standard and we can also produce fittings up to DN 2000.
