The connection method for Spiral Structure pipe is by one coupler with two pieces rubber rings.

The pipe end can be inserted into bell type coupler with two ruuber rings for sealing the connection.  

Both Spiral high density polyethylene (HDPE) and polypropylene (PP) pipes are available for a variety of applications. These applications include gravity flow storm and sanitary sewer, Iow head pressure applications as well as many others as deemed appropriate by the design engineer. 

Drainage systems often involve connecting pipes of different materials or sizes. Options to make these transitions are often limited by the joint quality required.

One very common method of connecting different types of pipe of the same size, and in some cases different sizes,is through the use of a concrete collar.

This generally provides a minimum silt-tight joint quality but the resulting quality ultimately depends on workmanship.
