costs
A range of diameters are available from 750mm up to 2100mm. Ridgistorm-XL is unique
in that it is designed and manufactured as a bespoke solution to suit each individual
project. By analysing the site conditions and installation parameters, using state
of the art software our Technical department can create a solution with the appropriate
profile strength and stiffness that is neither over nor under engineered for each
individual pipe. A wide range of profiles can be used to meet specific loading requirements
and ground conditions. Our production flexibility allows pipe strength to be produced
at varying stiffness classes to meet the design requirements of a project, without
the need to step-up pipe specification.
The flexible nature of plastic pipes ensures that they are more tolerant to deformation
and movement of the surrounding soil than rigid pipes, further minimising the risk
of leakage, a key factor when considering the Water Framework Directive European
legislation which puts a reduction in diffuse pollution as a critical objective.
Using the electro-fusion jointing method, 100% seal tightness can be achieved to
guarantee exceptional joint and pipe performance
Jointing Systems
Ridgistorm-XL can be designed and manufactured to suit any jointing requirement
on-site. EPDM, internal-welds and flange connectors can all be achieved with the
Ridgistorm-XL system, depending on the installation and application requirements
of the project.
Polypipe WMS offers the only large diameter plastic pipe solution with integral
electro-fusion jointing, ensuring 100% seal tightness and guaranteeing exceptional
joint and pipe performance.
In comparison with other large diameter systems, Ridgistorm-XL can be handled, jointed
and installed much quicker, resulting in time and cost savings on site.
Manholes
The flexibility and adaptability of the Ridgistorm-XL system, coupled with our vast
experience and the capabilities of our in-house fabrications team enables us to
design and manufacture bespoke man holes to meet site requirements. Off-set manholes
can be integrated into a Ridgistorm-XL pipeline or attenuation system to provide
easier maintenance access to the system. This utilises a unique step feature within
the construction of the manhole to reduce the need for direct access into the pipe
with improved health and safety benefits, particularly in foul sewers.
Ridgistorm-XL and all pipe profile options, stiffness classes SN2 to SN8 and diameters from 750 to 2100mm are approved by WRc. The approval also extends to all work carried out by Polypipe’s in-house Fabrications Department, the design software used to engineer the product (for SN1 - SN8) and Ridgistorm-XL’s unique and patented electro-fusion jointing method, which covers the tensile strength of each joint, the jointing method and Polypipe’s installation manual and guidance.
