1 WM22 Helden RESTRINE OULE FLNGE FITTING ESY TO INSTLL LLOWS FOR JUSTMENT 316 STINLESS STEEL FSTENERS

2 WM22 Helden eveloped for complete versatility, the range was developed to provide greater versatility for the designer at the planning stage and the engineer in the installation stage of flanged pipe work systems and to allow for simple maintenance programmes. LLOWS FOR JUSTMENT The s are double flanged fittings that accommodate up to 100mm (4 ) longitudinal adjustment and can be locked at the required length with the tie bars supplied. Not only does this system allow for fast, easy maintenance of valves, pumps or meters, it simplifies future pipe work modifications and reduces downtime when changes need to be made. ESY TO INSTLL The installation is also straightforward using just a spanner and torque wrench to tighten the high tensile steel or stainless steel tie bars. With fewer tie bars than flange holes and the tie bars acting as flange jointing bolts the process is speeded up but still offers a secure, rigid, fully end load resistant system with a pressure rating equal to that of the flange. THE RNGE comprehensive range is available from N40 (1½ ) to N2400 (80 ) with virtually any flange drilling or pressure rating supplied, although larger sizes and custom made s can be designed and built on request. Flanged Pipe Materials

3 FULL FLNGE SELING For applications where a full-face flange is required, i.e. wafer and butterfly valves, the flange of the spigot piece provides a full flange sealing area. EXELLENT ORROSION PROTETION The flange adaptor and flange spigot are coated with WRS approved Rilsan Nylon 11 providing excellent protection from transport, storage, site and corrosion damage. The tie bars are Zn 3 Zinc Plated as standard with other coatings, grades and finishes available on request. The nuts and bolts are Sheraplex coated to WIS , offering long term protection against corrosion. WM22 Helden ULTIMTE SELING PILITY The EPM gasket is compressed independently of the tie bars with the sealing capability secured as soon as the fasteners reach required torque. SIMPLE TO FIT Harnessing is accommodated within the bolt circle, eliminating other complex anchoring systems and reducing space requirements. USTOMER ENEFITS Helden s s are particularly suitable for simplifying the installation and removal of isolation valves, control valves, check valves, non-return valves, flow metering valves, pump sets, pressure reducing valves, flanged pipe and fittings. esigned and manufactured to S EN ISO 9001: 2008 and tested to the most exacting requirements of WRS (Water Regulatory dvisory Scheme) for use with potable water. The simplicity and versatility of the fittings make them suitable for many applications including pumping stations, water treatment works, sewage treatment works, plant rooms, meter chambers, power generation equipment, gas distribution stations.
