A jet pump slip joint repair assembly includes at least one clamp and a bushing configured to be inserted in a bore of a diffuser and to surround a portion of an inlet mixer. The clamp includes a gripping surface and a gripping collar. The bushing includes a generally cylindrical sidewall, the sidewall configured to surround the portion of the inlet mixer, a grooved flange on an upper surface of the sidewall, at least one cutout between adjacent portions of the grooved flange, and a groove on an inner, bottom surface of the sidewall. The assembly also includes a seal in the groove. The seal is flexible and formed of a metallic material. The seal is configured to be compressed when the at least one clamp engages the bushing.

An exhaust pipe forming a flow path of exhaust gas of a vehicle includes a first end including a first opening, a first flange portion formed on the first end, and a cover member. The first flange portion is configured to be fastened to a second flange portion formed on a second end of another exhaust pipe. The cover member includes a held portion and an inner circumferential portion. The held portion is held between the first end and the second end when the first flange portion and the second flange portion are fastened together. The inner circumferential portion covers a region adjacent to the first opening in the inner circumferential surface of the exhaust pipe.

A multi-petaled oblique-plane hoop and a pipe connector are described. The hoop is divided into two groups, and the hoop petals in each group are connected by means of pins, and the pins are parallel to a connecting pipe shaft. The groups are connected by using bolts, and the bolts are vertical to a pipe shaft. Each hoop petal is in a shape of a partial ring stud, in which an arc-shaped groove is formed. The upper surface and the lower surface of the groove are symmetrical partial inner cone surfaces, and the hoop petals are connected to form a clamping chain.

A device is for operation on a pressurized bolt connection between a first flanged tubular and a second flanged tubular. The device has a first clamping member with a first contact portion adapted to bear against the flange of the first tubular, a second clamping member with a second contact portion adapted to bear against the flange of the second tubular, and a connection arrangement for pulling the first clamping member and second clamping member together. The first contact portion and the second contact portion are adapted to bear at an inner part of the flanges between the bolts of the bolt connection and the body of the two tubulars.

A water heating device equipped with a housing, a fan and a chamber arranged in the interior of the housing, and screws. The housing has first and second side plates which oppose one another in a first direction and extend from the ends of a back plate along a second direction intersecting the first direction. An opening part is provided in the housing on the side opposite the back plate in the second direction. The fan has a discharge opening, a first flow passage extending along the first direction, and a first flange. The chamber has an intake opening, a second flow passage extending along the first direction, and a second flange. The first and the second flanges are secured by screws. In a planar view, the center axis of the screws is slanted such that a head portion is closer to the opening part than the tip-end portion.

The disclosure is based on the idea of providing a pipe flange coupling device (3), which is attachable in connection with a first pipe (1) of a first pipe flange (1a), having pawls (6) engaging a second pipe flange (2a) of a second pipe (2). The pawls (6) are fixed to a spindle (5) retractable by a translation arrangement so as to pull the second pipe flange (2a) against the first pipe flange (1a). More particularly, the translation arrangement is configured such that, when the flanged pipes (1, 2) are coupled and the pawls (6) are retracted, a force exerted on the pawls (6) towards the extended position is transmitted via the translation arrangement against a mechanical stopper. Moreover, the translation arrangement is biased such that the translation arrangement must work against this bias in order to extend the pawls and release the flanged pipes (1, 2) coupled to each other.
