UltraGrip Amplified for Prague Water
Posted on 22th Aug 2024
Viking Johnson has supplied UltraGrip couplings with flange adaptors to a key channel partner TRAN-SIG-MA. This is a refurbishment project of a pipeline network in Jeremiasova Street, in central Prague for the largest water and wastewater utility company in the Czech Republic, Prague Water. This water main is a critical city artery serving 85,000 people from a water storage station based outside the city, in Kopanina.
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.
