ABSTRACT:
Lengths of "plain-end" pipe are joined together in underground sewer or drainage systems by flexible sleeves having a specified column expansibility and shear-resistance and containing high modulus helically oriented reinforcement, bonded or encapsulated in elastomeric material. The resultant pipe assemblies represent a significant improvement over previously known "plain-end" pipe-coupling arrangements and bell and spigot pipe assemblies. Pipe sections may be quickly and economically joined without inserting packing, to provide a water-tight, shear-resistant joint which will accomodate significant angular misalignment and circumferential variation. Even if lubricant is placed on the inner surfaces of the flexible sleeves to reduce assembly forces, the resultant pipe assemblies still exhibit more than adequate resistance against shear loads and water infiltration.
