Puddle Flanges

PE Puddle flanges perform the same as Ductile Iron (DI) Puddle Flanges. Designed for encasement in concrete, where PE passes through a structure (typically a concrete wall). Because PE is an 'end to end system' a PE puddle flange must withstand loads that exceed the ultimate tensile strength of the pipe, meaning Pipe fails first in a tensile pull to failure.

Mill-Pro puddle flanges are either injection moulded in PE100+ or machined from a single piece of extruded PE100+ hollow bar. They contain no welds or joints in the puddle area. (between the tapered sections).

In reclaimed land (for which PE is perfectly suited to), designers should consider to total force applied to a concrete structure, by the pipe pulling on the structure as it sinks with the settling ground. Click here for a more detailed presentation on settlement loadings.

Unlike DI, PE will not naturally form a leak-free seal when embedded into concrete. PE expands when surrounded by mass concrete, due to the increase in temperature of curing concrete.  Once the concrete cools, the PE reverts to its original size leaving a small gap between the PE and the concrete, this gap allows waste or ground water to pass into or out of the structure.  

Hydrophilic vulcanised expansive rubber sealing rings are fitted to a groove in the puddles ring.  The Hydrophilic ring expands >600% when exposed to moisture.  Rings are supplied as standard and comply with ASTM D471. They must be kept dry in until they are embedded in concrete.

NOTEThis product is not suitable for making pressure connections such as the base of a reservoir. Hydrophilic sealing rings are a water stop, not a pressure seal.  They are designed to expand into the surrounding structure and provide a barrier to groundwater ingress or egress typically found in chambers or structures, a few meters below ground level.
