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.

Various fittings capable of preventing distortion are disclosed. The fitting comprises a metal member configured to have at least two sub metal members and a body. Here, the sub metal members are included in the body, and the body is formed of plastic.

A connecting system for connecting components in a vehicle includes a first elongate element with a first connecting face at a first end, and a second elongate element with a second connecting face at a second end. The first and second elements each comprise holding devices distributed along an annular connecting line. The connecting faces are congruent. The connecting faces and holding devices are configured to be brought into a flush superficial contact when the orientations of the elongate elements coincide, and the mutually opposing holding devices then connect with one another. One of the elements has a length adjustment component configured to change a position of the respective connecting face in a longitudinal direction of the respective element. The connecting faces comprise at least one pair of connectable interfaces which correlate with one another in pairs for transfer of a fluid, electrical or optical signals or electrical current.

In various embodiments, the stabilizing face ring joint flange and assemblies thereof can be adapted to include a ring joint gasket and resist leaks when a fluid flowing through a pipe at high temperatures and pressures. The stabilizing face ring joint flange assembly with the ring grooves in each flange can be situated in such a way that once full compression is achieved on the ring groove by the gasket, raised faces of the two flanges can meet to ensure that the rotation of the pump or any potential perpendicular loading do not provide a stress on the gasket that would cause the gasket to deform or cause a seal to be lost.

A block fitting assembly comprises a first block having a first fastener aperture formed therethrough, a second block having a second fastener aperture formed therethrough in axial alignment with the first fastener aperture, and a fastener extending through the first fastener aperture and the second fastener aperture to couple the first block to the second block. The block fitting assembly includes a thermal expansion compliancy feature in the form of at least one of an inner surface of the second block defining the second fastener aperture including an axially extending non-threaded portion adjacent a threaded portion thereof or the fastener including a necked portion having a smaller outer diameter than a minor thread diameter of a threaded portion of the fastener.

The invention relates to a pipe connection (10, 52, 66) with a first pipe part (12) and a second pipe part (14), with at least one multi-part sealing ring (24; 44, 46) or at least one single-part sealing ring (68) which is surrounded by a clamping device (16). The pipe parts (12, 14) each comprise a first obliquely or vertically extending end face (20, 72) or a second obliquely or vertically extending end face (22, 74). These are overlapped by a clamping device (16). This applies an outwardly acting radial force (34) to the at least one single-part sealing ring (68) or the at least one multi-part sealing ring (24; 44, 46). These are secured in their respective sealing position by means of an enclosing geometric triangle, by means of an enclosing geometric non-rectangular quadrilateral (104) or by means of an enclosing geometric rectangular quadrilateral (106).
