Water pipeBLUFORCE RJ

polymer for high-pressure applications construction

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 managing body 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 is the ideal piping system for horizontal directional drilling. Test on pressure All pipes of the FITT Bluforce RJ range have been subjected to 1,000-hour regression tests in accordance with the EN 1452 standard with internal pressures conforming to the design MPa values, and they amply passed the tests without any leakages or fractures. Thanks to the data derived from tests at 1,000 hours, it is possible to identify the axial tightness of the restraint joint fitted on FITT Bluforce RJ, with values ranging from a minimum of roughly 20 kN for DN 90 PN 16 pipes to a maximum not exceeding 440 kN for DN 400 PN 20 pipes.
