Products Flexseal Unisaddle FA150U ● Universal saddle for all DN150 lateral jobs ● Fits clay or concrete mains from 300mm to 27.5mm diameter ● accepts branch connections from any DN150 pipe ● Withstands internal pressure of 1 bar, shear load of 30 bar ● Deflection of lateral pipe up to 7 degrees Focus on…pipes and fittings What it is: The new multi-purpose Unisaddle Fa150U, just launched by Flexseal, offers a 'one-size-fits-all' lateral connection for thick wall pipe. The Unisaddle will fit all sizes of clay or concrete main sewer or surface water pipes from 300mm down to just 27.5mm. It will also accept branch connections from any 150mm pipe, regardless of pipe material, with the addition of a Flexseal multibush. How it works: The product's adaptability comes courtesy of a set of rubber shims, supplied on the product. The user simply needs to remove the correct number to achieve a secure fit onto the main pipe. Equally, the multibush assures the perfect fit on the lateral pipe, offering 4 different permutations. The fitting can withstand internal pressure of 1 bar, a shear load of 30 bar, and deflection of a lateral pipe of up to 7 O . What they say: "The new product is the most universal of its kind and we believe it can add real value to contractors who need to make an unexpected lateral connection or those who just want to simplify the way they make lateral connections," says mark Chatterton, manager of Flexseal's R&D team. HOBAS GRP pipes The new HOBaS Top Performance Pipe is equipped with an exceptionally durable inner protective layer made of polyurethane resin, the thickness of which is customized for each project individually, typically starting at 2 mm. This special layer makes the pipe extremely resistant to abrasion, corrosion and impacts. Thanks to its particularly smooth inside surface, it also features excellent hydraulics and prevents sedimentation. The wall structure of the centrifugally cast (CC) GRP pipe can also be customized for special project conditions. Plasson 3703 stop valve Plasson has added to its extensive valve range with the first WRAS approved stop valve for 50mm (11/2") and 63mm (2") mains pipes manufactured from non-metallic materials. The Plasson 3703 has been developed in response to demand from the utilities for lead free products. manufactured from glass reinforced polyamide, the 3703 now provides an alternative solution to the traditionally used gunmetal and dzr stop valves currently still in daily use. Rated to 16 bar, the full range of valves covers ½" to 2". Durapipe LR valve Durapipe UK has launched a new dual action valve, offering more flexibility to contractors, consultants and end users. The Durapipe LR valve's bespoke design offers both pressure loading and pressure relief options within one valve body: the pressure loading function allows a back pressure to be built up within a pipe system of between 0 – 3 bar, helping to control system pressure in the event of sudden pressure loss. alternatively, the valve can also be installed in an alternative orientation by turning the valve 180 degrees, allowing the valve to act as a pressure relief valve.
