A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.

Method for joining a fluid conduit and a connection hub. There is provided a method for joining a fluid conduit 2 and a connection hub 7, wherein a fluid 2 conduit is provided having an at least partially transparent end section 1. Also provided is a connection hub 7 comprising a hub cavity 9 having a shape complementary to a shape of the end section of the fluid conduit 1. The end section of the fluid conduit 1 is at least partly introduced into the hub cavity 9 through an opening in the hub, wherein a contact interface between at least a lateral wall part of the end section 1 and a hub cavity 9 wall is established. The method includes heating a target zone 27 in the contact interface, for joining the fluid conduit 2 and the connection hub 7 at the target zone 27, by directing a light beam 29 across the at least partially transparent end section 1 of the fluid conduit 2 from a side of the fluid conduit 2 which is opposite a side of the target zone 27.

A pipe device includes a pipe and a connection element. The pipe has a pipe jacket that has an inner surface and an outer surface and forms a flow channel. The connection element forms a through-channel that extends from a connection piece consisting of a first material (M1) and having a first opening to a second opening. The pipe jacket is positioned on the connection piece with a first pipe end consisting of a second material (M2). A bonded connection is formed between the first material (M1) and the second material (M2) in a contact region between the inner surface of the pipe jacket and a peripheral surface of the connection piece.

A manufacturing method for manufacturing a pipe joint including a circular tube-shaped housing and an elastically deformable circular tube-shaped seal member provided at an inner peripheral side of the housing. The pipe joint manufacturing method includes a process of placing the seal member inside a mold in a state in which the seal member is fitted to an outer periphery of a retaining pin, and a process of causing a molten resin to flow into the mold so as to mold the housing in a state in which the seal member is cooled through the retaining pin.

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.
