Provided is a joint for high-pressure pipes, which allows improved efficiency in pipe replacement work as well as improved seal performance and resistance against vibration of a pipe joint. The pipe joint for coupling a first pipe and a second pipe comprises: a first joint for coupling with a first pipe; a second joint for coupling with a second pipe; a clamp having a band portion that overlaps an abuttment part for of the first joint and the second joint, and that couples the first joint to the second joint in an abutting state; and a tightening element for shrinking the internal diameter of the band portion by a tightening operation. The external diameter of each end part of the first joint and the second joint in the abuttment part is larger than the external diameter of intermediate portions of the first joint and the second joint. The inner face of the band part is formed such that when the first joint and the second joint are in abutting state, each of the end parts of the first joint and the second joint fits the inner face of the band part of the clamp.

Provided is a seal ring structure for a high-pressure pipe joint that is capable of improving the sealing performance and vibration resistance of a pipe joint. The seal ring structure comprises a seal ring and a retainer. The seal ring is donut shaped. A cross-section of the seal ring comprises a quadrangle having two diagonal lines that are orthogonal to each other. One diagonal line is parallel to a planar perpendicular line formed by the donut shape, and opposing vertexes on the diagonal lines are in contact with the end face of each joint. The retainer is able to engage with the peripheral edge of the joint end face.

A gasket having a core member having an opening, an inner seal portion made of elastic material and formed along an inner circumference of the opening, an outer seal portion made of elastic material and formed along an outer circumference of the core member. The core member has a seal-forming thin portion and an easily-deformable portion, the seal-forming thin portion being configured to form the inner seal portion at the inner circumference and to form the outer seal portion at the outer circumference, and the easily-deformable portion being provided between the inner seal portion and the outer seal portion and being configured to easily deform the core member.

Eine Vorrichtung (2) zur Verbindung einer Rohrleitung (4) mit einem Gegenstück (6) weist in einem Endabschnitt (8) der Rohrleitung (4) eine Verdickung (12) auf, die im Querschnitt (dv) gegenüber dem restlichen Endabschnitt (8) erweitert ist, wobei die Verdickung (12) eine erste Dichtfläche (14a) aufweist, die die Form eines Kegelstumpfes oder einer Kugelschicht aufweist und sich zur ersten Auslassöffnung (10a) hin verjüngt, und das Gegenstück (6) eine zweite Dichtfläche (14b) aufweist, die die Form eines Konus (7) aufweist, wobei erste (14a) und zweite Dichtfläche (14b) nach Art einer Dichtung (16) zusammenwirken, wobei die Verdickung (12) eine erste Stützfläche (18a) aufweist, und die Vorrichtung (2) ein Klemmmittel (20) enthält, das kraftübertragend am Gegenstück (6) und an der ersten Stützfläche (18a) angreift, um die Rohrleitung (4) mit ihrer ersten Dichtfläche (14a) gegen die zweite Dichtfläche (14b) des Gegenstücks (6) zu pressen. Die Vorrichtung findet Verwendung zur Verbindung einer ein Gas, insbesondere Wasserstoffgas, führenden Rohrleitung (4) mit einem Gegenstück (6).

The present disclosure relates to purification cassettes that have reinforcing features. One embodiment relates to a purification cassette with tensions members. A purification system may include a removable cassette defining a media cavity. A set of tension members may span between a first sidewall and second sidewall. The set of tension members can divide the media cavity into a plurality of lanes.

The connector includes a sleeve (4) which is screwed on to a thread (18) provided on an upper axial end of the lower riser section (1). The sleeve (4) encloses a lower end of an upper riser section (2) and is retained thereto. Once the sleeve (4) is secured to the lower riser section, this loosely secures the upper riser section (2) to the lower riser section (1). A tensioning tool then stretches the sleeve (4) upwardly and a retaining collar (5) is then maneuvered in order to retain the sleeve (5) in this tensioned state after the release of the tensioning tool. This creates a preloaded connection between the upper riser section (2) and the lower riser section (1).

This disclosure relates generally to hose couplings useful for mining applications, more particularly to a fluid coupling capable of generally fully tightened by hand, including a visual lock for visual indication and safety when in a hand-tightened position. The coupling generally includes a male portion, a female portion, a retaining member and a locking member. The male portion passes through the retaining member, and the retaining member threadingly engages the female member. The locking member prevents unthreading of the retaining member from the female member.
