04 Apr Wide radius restraint joint bends: the benefits of their use in the Sinis Sud irrigation project
For the major irrigation project planned in the Sinis Sud district, a peninsula located in the central-western part of Sardinia, FITT Bluforce and FITT Bluforce RJ pipes were selected as improved solutions compared to the PVC-U pipes initially identified.
The project, thanks to which a consortium irrigation infrastructure with a territorial extension of approximately 2700 Ha will be realised, will see the installation of the following FITT Bluforce RJ wide radius restraint joint bends: 20 PN16 DN400 45° bends, 6 PN16 DN250 90° bends, 2 PN16 DN160 90° bends.
In addition to guaranteeing the many benefits of PVC-A, such as flexibility, mechanical strength and durability, the wide radius restraint joint bends are able to respond effectively to the many requirements of building companies, designers and integrated water system utilities.
Restraint joint system
The FITT Bluforce RJ range is characterised by the presence of the Bulldog® seal, a socket-based jointing system with the seal mechanically hot-inserted in advance during the socket forming phase.
The hot pre-insertion of the seal, in addition to guaranteeing absolute stability of the gasket itself, ensures ease of assembly and high hydraulic and mechanical sealing performance.
The elimination of anchor blocks
Thanks to the use of the Bulldog® sealing system, there is no need to use concrete anchorage blocks, which normally have a considerable bulk and performance influenced by the type of soil.
The elimination of anchor blocks considerably simplifies installation and calculation operations, making the intervention of designers, building companies and integrated water system utilities easier.
A wide, high-performance range
The restraint joint bends are able to cope with wide bending radii, with angles of 45° and 90°, in diameters 90, 110, 160, 200 and, on request, up to diameter 400.
The pipe-laying operations, that will start in the coming months, will allow the installation of the FITT Bluforce RJ wide radius restraint joint bends to be followed more closely.
