  • Publication number: 20230160510
    Abstract: A flexible pipe end portion connection structure is provided. The flexible pipe end portion connection structure includes a flexible pipe body and a joint. The joint includes a first end and a second end opposite to each other and has a channel extending through the joint in a direction from the first end to the second end. An inner sidewall of the first end of the joint has a plurality of first stepped structures, and an inner diameter of a portion of the channel corresponding to the first stepped structure gradually decreases in the direction from the first end to the second end. At least a part of an end of the flexible pipe body is inserted into the first end of the joint to fit with the first stepped structure.
