Problems solved by technology

Since this destructive sampling is only done on a statistical basis, it is still possible that the fluid conveying member to be used will not have a swaged connection that is entirely adequate for the intended use

Embodiment Construction

[0031] figure 1 An exemplary fluid conveying member in the form of a tube 10 is shown along with an example flange 12 for interconnecting the tube 10 with a coupling (not shown). figure 1 The illustrated flange 12 is representative of the coupling means commonly used in interconnecting fluid conveying members conveying volatile fluids. Examples of US patent references disclosing couplings incorporating similar tube and flange combinations include US Patent Nos. 6,050,609 and 6,880,859. Both of these references are incorporated herein by reference in their entirety for disclosing example coupling arrangements for interconnecting facing ends of fluid transport members specifically designed for transporting volatile fluids, such as fuel.

[0032] figure 1 The basic features of the pipe 10 and flange 12 are also shown. The tube has a distal end 14 inserted into flange 12 . The inner surface 16 of the tube 10 is in contact with the fluid being conveyed. The outer surface 18 of...

Abstract

A swage visual indicator for a fluid coupling is disclosed and related methods. The swage visual indicator is achieved by a non-destructive visual indication of a swaging process by one or more swage apertures (34) formed through a flange (12) filled with an indicator material (40). The swage apertures (34) communicate with swaging grooves (32) of the fluid conveying components being joined. As the swaging process is conducted, the swaging grooves (32) are filled with material from one of the fluid conveying components, and the indicator material (40) within the aperture(s) (34) is therefore displaced in a direction toward the exposed exterior surface of the flange (12). According to a successful swaging process, the indicator material (40) is displaced to a degree such that the indicator material (40) is visible by the unaided eye of an inspector.

Description

technical field [0001] The present invention relates to fluid conveying members interconnected, for example by coupling means, and more particularly to fluid conveying members having ends incorporating corresponding flanges secured to the coupling means, wherein the fluid conveying members and flanges are formed by swaging / swaging The forging / swaging process is linked. Background technique [0002] There are numerous inventions relating to fluid transport members or conduits, and various coupling arrangements that can be used to interconnect fluid transport members. The specific design of the coupling device, as well as the design of the fluid conveying member, is usually dictated by the special requirements associated with the type of fluid being conveyed. For delivery of non-volatile liquids such as water, the coupling may have a simpler structure, as potential leakage in many applications may not cause significant health or safety concerns. In contrast, for fluid transf...
