  • Flexible Pipes for Culvert and Drainage Appliions

    Understanding how the flexible pipe relates to its neighboring soil — thereby establishing a functional pipesoil composite structure — is key to a successful design (Gabriel, 1998). The addition of thermoplastic flexible pipe with different longterm strength characteristics has resulted in design criteria specific to that material.

    For example, if I have solid cylinder from steel with 10 cm radius, area will be 314 square cm, and if I have pipe from the same steel with external radius 20 cm and internal radius 17.32 cm, area and mass per meter length will be the same as cylinder 10 cm radius. What can handle more compressive force pipe or cylinder or it will be the same?
