This document is the TN 5.11 Sliplining Extended Lengths with HDPE Pipe. It explains integral bell transition for HP pipe products.

ADS offers a variety of joints to the marketplace. HP pipe products are manufactured using polypropylene resin and is available in 12” through 60” with exterior corrugations (dual wall), while 30” through 60” may also be available with an exterior shell (triple wall). The HP products are also available for storm and sanitary sewer markets. While HP pipe can be cut in the field, the connection method must be based on the allowable joint performance for the project.

ADS HP pipe products have an integral bell which maintains a constant pipe outside diameter (OD). This constant OD eliminates the need for bell holes and makes it easier to maintain line and grade during installation. The bell and spigot design for HP products, with an elastomeric rubber gasket meeting ASTM F477, meets or exceeds the watertight testing requirements outlined in ASTM D 3212.

Connections for HP Pipe have a variety of couplers available, connecting to an existing pipe run or a fabricated fitting may necessitate a transition to other ADS joints. ADS fittings come standard with a plain end, welded bell end or IB bell or spigot end; the end treatment will be based on fitting diameter and available configurations are available in the ADS Fittings Manual. Standard large diameter or custom fittings utilizing IB joints require no additional field work for the connection.

Integral Bell Pipe to Plain End Pipe (12” – 60”) (Plain End Pipe/Fitting Connections)

are for storm Drainage Only as specifications permit. Remove the bell or spigot end of the pipe. The spigot end on 12”-60” pipe will have mini or reduced-size corrugations. To

achieve a soil-tight joint, a split band coupler may be utilized to connect 12” - 60” dual wall pipe and a Mar-Mac® coupler may be utilized to connect 12” - 60” dual or triple wall (where applicable) pipe.
