Dilatation compensators are installed in pipelines as elements primarily intended to compensate displacements resulting from thermal and other dilatations. In addition to this, they enable easy and simple installation of pipe armature elements and measuring and regulating devices using the available displacements within the limits.
The area of production of such expansion joints with regard to nominal diameters and pressures can be seen from the relevant tables, and the maximum allowed temperatures of the working fluid are 80 ° C to 120 ° C or 200 ° C, depending on the sealant.
Simple and reliable construction, performed by welding, meets all the requirements of safety and functionality.
Types A and B are for temperatures up to 120 ° C and type C for temperatures of 120 ° C and 200 ° C.
Flange connection dimensions comply with SRPS M.B6.011 and DIN 2501.
For non-aggressive fluids, the production of such expansion joints is made of structural steels, and for aggressive ones, of steels resistant to chemical influences.
The sealing ring, depending on the temperature of the working fluid, is made of EPDM, special EPDM or graphite cord.
