UltraGrip Amplified for Prague Water
Viking Johnson hat UltraGrip-Kupplungen mit Flanschadaptern an einen wichtigen Vertriebspartner, TRAN-SIG-MA, geliefert. Es handelt sich um ein Sanierungsprojekt eines Rohrleitungsnetzes in der Jeremiasova-Straße im Zentrum von Prag für den größten Wasser- und Abwasserversorger der Tschechischen Republik, Prague Water. Diese Wasserhauptleitung ist eine wichtige städtische Versorgungsader, die 85.000 Menschen aus einem außerhalb der Stadt in Kopanina gelegenen Wasserspeicher versorgt.
The project was complex and involved renewal of an existing DN800 steel water main pipeline by replacing a section with new ductile iron pipework, plus upgrading of an old existing gate valve with a new eccentric butterfly valve, to have better control of fluid flow, as well as adding in new hydrants to the system, connecting to a DN600 pipeline.
UltraGrip was the ideal in this situation as it was also able to cope with misalignment of the DN800 steel pipe which had an angular deflection of about 5 degrees and easily met the pressure requirements of 8 bar and can be fitted to a wide variety of pipe materials.
