This appraisal is for a range of Flowtite Filament Wound Glass Reinforced Plastic (GRP) pipes and associated fittings for water and sewerage applications. This Issue 7 is to update the Appraisal to align with WS PS 219 which calls up ISO 23856:2021 and includes details of Australian preferred outside diameters.
The pipes are available in sizes from DN 300 to DN 3000 with nominal pressures from PN1 to PN32 and standard pipe stiffness ratings of SN2500, SN5000, SN10000 or SN20000. Other stiffnesses and higher pressure ratings can be supplied upon request.
The pipes are designated as Series B, based on the external diameter of the pipe.
DN 300 to DN 750 pipes have spigot outside diameters complying with Australian Standard ductile iron pipe OD’s. DN 900 to DN 3000 pipes have spigot outside diameters complying with ISO 23856 Table 5 Series B1.
The standard length of Flowtite pipes is 3m, 6m or 12m although specific lengths up to 13m can be manufactured.
A range of pipe fittings are moulded or fabricated using the same materials that are used to produce the Flowtite pipe.
