摘要:
Die vorliegende Erfindung betrifft ein Verfahren (101) und eine Vorrichtung (3) zur Überprüfung der Vormontage eines Schneidrings (1) auf einem Rohr (2). Das Verfahren (101) dient zur Überprüfung der Vormontage eines Schneidrings (1) auf einem Rohr (2) mit einer Vorrichtung (3) mit mindestens einer optischen Erfassungseinrichtung (4) zum Erfassen (102) von Bilddaten in einem Erfassungsbereich (5), aufweisend mindestens die nachfolgenden Verfahrensschritte: - Erfassen (102) von mindestens ersten Bilddaten mindestens eines zumindest teilweise in den Erfassungsbereich (4) eingebrachten Rohres (2) mit vormontiertem Schneidring (1), - Auswerten (103) zumindest eines Teils der ersten Bilddaten in Bezug auf eine Lage des Schneidrings (1) zum Rohr (2) und/oder geometrische Eigenschaften des Rohres (2) und/oder geometrische Eigenschaften des Schneidrings (1).
摘要:
A conduit fitting of the type having first and second threaded fitting components and at least one conduit gripping device, further includes a stroke limiting member that allows the fitting to be pulled up by applying a predetermined torque. In one embodiment, the stroke limiting member may realized as an integral or integrated load bearing member that functions as a torque collar and deflects under load. The disclosure also presents a gauging structure and method for fittings that can be pulled up by turns, by torque or both.

The present application discloses methods and apparatus for installing fitting components, such as a conduit gripping device, on a conduit to form an assembly. The assembly is joinable with at least one other fitting component to form a fitting. The present application also discloses methods and apparatus for evaluating characteristics of components of a mechanically attached connection. Characteristics that may be evaluated include, but are not limited to, the position of a conduit gripping device on a conduit, an amount of axial compression or stroke of the conduit gripping device, an amount of clamping force applied to the conduit gripping device as the conduit gripping device is compressed, and an amount of torque applied to members that compresses the conduit gripping device.

A ferrule and associated method characterized by an outer layer having a hardness; an intermediate layer below the outer layer, the intermediate layer having a hardness that is less than the hardness of the outer layer; and a core below the intermediate layer, the core having a hardness that is less than the hardness of the intermediate portion.
摘要:
The present invention relates to a tube fitting which is designed to be easily checked by visual inspection as to whether the nut tightening reaches a reference value. The tube fitting comprises a tube inserted into a body, at least one ferrule disposed around the tube, and a nut tightened onto the body to deform the ferrule for providing a seal between the body and the tube. If the nut is tightened on the body to a reference value, a check ring is detached from the body by a pressing force of the nut such that the coupling state of the nut can be checked.
