Split puddle flanges are designed for use on the bodies, if pipes are produced by the centrifugal casting method, i.e., spigot and socket spun pipes or flanged spun pipes. They are not suitable for use on the bodies of sand cast items.

Split puddle flanges are used to provide a water bar where a pipe passes though a wall. They should not be used to provide an anchorage for the pipe.

The flange is fitted to the pipe using sheeting of lead, asbestos fibre, rubber, roofing felt or similar material to provide a packing between the flange and the pipe body.

After the flange is bolted around the pipe, the circular chamber formed on one side of the flange is caulked with lead and yarn. Lead wool or lead substitute to affect the watertight seal. The caulked side of the flange should be towards the waterlogged side of the structure.
