Abstract
A system of connecting two flexible tubes together using the rolled back ends of the tubs to create abutment surfaces which when urged together for a fluid-tight seal. The rolled back ends are supported on tube supports including a spigot extending along the outside of the tube and over which the rolled ends are supported. Urging two rolled backed ends together creates a fluid tight seal. This may be achieved by attaching flanges to the rolled back ends and using standing clamping means. Alternatively, other types of clamping means can be used.
Claims20
A method of connecting two lengths of flexible tube, the method comprising
- forming a first sealing end from a length of a first flexible tube by rolling an end portion of the first flexible tube back on itself to form a first rolled back end portion, wherein rolling the end portion of the first flexible tube elastically deforms the first sealing end creating a bias force;
- forming a second sealing end from a length of a second flexible tube by rolling an end portion of the second flexible tube back on itself to form a second rolled back end portion, wherein rolling the end portion of the second flexible tube elastically deforms the second sealing end creating a bias force;
- directly abutting the first sealing end and the second sealing end against each other to create the fluid tight connection, wherein relaxation of the bias force of the first and second sealing ends maintains the fluid tight connection.
