The experience acquired in recent years with the production and promotion of the polymer alloy technology has confirmed the need to supply market players with a premium-quality product that is also capable of satisfying the highest technical-application standards in both the integrated water resources management market and the irrigation sector.
The overall expenditure for important projects such as water supply pipelines, sewage lifting stations and water infrastructures depends on the initial costs, but above all on the management and maintenance costs throughout the entire service life of the infrastructure, which should be as durable as possible and trouble-free.
To satisfy these needs, FITT – after developing the innovative FITT Bluforce technology and incorporating the inputs coming from the market (designers and managing bodies) – presents FITT Bluforce RJ: for the first time in Europe, a pipe made of thermoplastic material with an integrated and immovable mechanical sealing systeme.
FITT Bluforce RJ conforms to the IIP 1.1/19 technical specification, “Modified polyvinyl chloride (PVC-A) pipes for water conveying pipelines”, (Italian) Ministerial Decree no. 174 of 6 April 2004 (Water for human consumption) and the UNI EN 1622 standard, “Water analysis – determination of the threshold odour number (TON) and the threshold flavour number (TFN)”.
FITT Bluforce RJ, – where “RJ” refers to “restraint joint” – can solve a series of necessities concerning both the design and laying phases, besides ensuring durable operation.
For designers it is far easier to design pipelines with restraint systems that do not require complex calculations to create thrust blocks; moreover, with the same type of pipe they can create sections that require mechanical seals and sections that do not require this technology.
Likewise, the company will have an easier task in laying the pipes, as they do not require external joints or, alternatively, concrete thrust blocks to be fitted in the restraint sections. Moreover, like for other polymers, long and delicate material welding operations are no longer necessary.
For the site management, it is an optimal solution for safely and rapidly completing network extensions and maintenance works on existing pipelines, resulting in shorter work times on-site without adversely affecting the durability of the polymer alloy technology.
FITT Bluforce RJ uses the socket-based jointing system with the seal mechanically hot-inserted in advance during the socket forming phase. The Bulldog® seal is made up of three elements that guarantee both the hydraulic and mechanical tightness of the joint:
This hot pre-insertion method guarantees a totally stable seal, resulting in easy assembly, perfect functionality and optimal hydraulic and mechanical tightness of the pipes over time. The Bulldog® system is characterised by:
Thanks to this technology, it is possible to build pipelines without creating thrust blocks. Moreover, the pipes can be laid on terrains that are strongly sloping or prone to landslides.
Horizontal Directional Drilling is a trenchless technology, suitable for installing new pipes without excavation. HDD greatly reduces disruption to traditional sites and, often, is the only solution for bypassing immovable obstacles in normal trench construction.
FITT Bluforce RJ is FITT’s thermoplastic pipe with built-in, integrated mechanical and hydraulic seal that meets the needs of designers, contractors, and water network managers.
The dual chamber seal, which is mechanically pre-inserted using heat, offers easy installation, perfect functionality and optimum hydraulic and mechanical sealing for the pipes. It also allows for installation on steep slopes or those subject to movement, making FITT Bluforce RJ ideal for trenchless operations such as Horizontal Directional Drilling (HDD).
Pipe assembly occurs during pullback phase and the impact on the site area is minimised. Handling is also much easier than with steel, cast iron – which are heavier and difficult to move – or polyethylene, materials that have been used in these types of application until now.
FITT Bluforce RJ conforms to the IIP 1.1/19 Technical Specification, “Modified polyvinyl chloride (PVC-A) pipes for water conveying pipelines”, (Italian) Ministerial Decree no. 174 of 6 April 2004 (Water for human consumption) and the UNI EN 1622 standard, “Water analysis – determination of the threshold odour number (TON) and the threshold flavour number (TFN)”.
In 2020 FITT Bluforce RJ obtains the certification Kiwa Quality thanks to which, based on type tests as well as the periodic inspections conducted by Kiwa, is deemed compliant with the requirements of the Technical Document Ki-0410 Rev. 11, Annex K75 Rev. 02 and therefore marked KQ. Kiwa certification was issued in agreement to the Kiwa Cement Italia Regulations for Certification of product.
FITT Bluforce RJ is offered in the RAL 5010 blue version.
