DESO Pipe Joints Production

- May 24, 2018 -

DESO Couplings are produced by filament winding. To meet the same quality standards as for the pipes, DESO Couplings are fitted with a high quality EPDM gasket (membrane). The computerized machine for manufacturing the couplings operates as follows: First it places a prefabricated EPDM membrane on the steel mandrel and then winds glass roving impregnated with polyester resin around it. At the same time, it sprinkles cut roving onto the coupling to reinforce the axial strength. After the laminate is in place, the resin starts to polymerize once exposed to light.
