Method of making a flexible conduit with loop portion
A recently granted patent (Publication Number: US11898645B2) discloses a method for producing a flexible conduit with a loop portion. The method involves using a double cross-shaped tubing section, along with two Y or TEE tubing sections, connected through overmolded connectors. These connectors ensure the bonding of the three separate tubing pieces, minimizing hold-up volumes within the conduit when closed by valves positioned around the intersections. The spacing between the sections allows for a flexible tubing portion, enhancing the efficiency of the conduit.
Furthermore, the patent details the use of mandrels during the molding process to form the overmolded connectors, which are designed as bubble connectors or made from silicone. By positioning the mandrels inside the tubing sections and the double cross-shaped section, the connectors are formed before the mandrels are removed, ensuring a secure and efficient connection. This innovative method aims to improve the functionality and performance of flexible conduits, particularly in applications where minimizing hold-up volumes is crucial for operational efficiency.
