An improved coupling system for joining two items together, typically in the form of copper pipes, to other copper pipes, or in the form of other fittings, includes a pair of flange couplings, each of which is independently secured to one of the items to be joined together so that when the two flange couplings are securely joined to each other by suitable fasteners received through fastening apertures in the two flange couplings, the two items are sealingly joined to one another to form a substantially water tight junction. The improvement being that the bare metal parts of the ferrous components of the coupling are coated with a protective coating, such as a copper coating, so that there is no direct contact between two dissimilar metals thereby inhibiting or preventing corrosion of the metal components of the coupling due to electrolytic or galvanic action arising from direct contact between the two dissimilar metals.

Provided is a method that is for attaching a filler pipe. The method for attaching a filler pipe attaches a filler pipe to the aperture of a fuel tank with an attachment member therebetween, and is characterized by containing: a fitting step for fitting the tubular attachment member to the inside of the aperture of the filler pipe; a contact step for contacting, to the surface at the periphery of the aperture of the fuel tank, a first flange protruding outwards in the radial direction from the outer peripheral surface of the attachment member, and a second flange protruding outwards in the radial direction from the outer peripheral surface of the filler pipe; and a welding step for welding the first flange and second flange to the surface.

One aspect of the invention provides an energy-dissipative fuel gas tube including: a length of corrugated stainless steel tubing; an inner resin layer surrounding a radially outer surface of the corrugated stainless steel tubing; a laminated foil layer surrounding a radially outer surface of the inner resin layer; and an outer resin layer extruded over a radially outer surface of the laminated foil. The laminated foil layer includes: a foil and a high-tensile-strength material bonded to the foil. Another aspect of the invention provides an energy-dissipative fuel gas tube including: a length of corrugated stainless steel tubing; a resin layer surrounding a radially outer surface of the corrugated stainless steel tubing; and a laminated foil layer surrounding and bound directly to a radially outer surface of the resin layer. The laminated foil layer includes: a foil and an outer protective layer bonded to the foil.

The pipe coupling member has a female pipe coupling body, and a cylindrical front and rear cover members fitted to the female pipe coupling body. The front cover member includes a communication assembly including a communication terminal, a communication cable extending rearward from the communication terminal inside the front cover member and further extending rearward from the rear end of the female pipe coupling body, and a connector terminal at the rear end of the communication cable. The rear cover member is configured to allow the connector terminal to be passed forward inside the rear cover member along a hose attached to the rear end of the female pipe coupling body when the rear cover member is displaced rearward in a state where the hose and the communication cable are allowed to pass inside the rear cover member.

Structural body comprises a concrete core and a cap around the opening. A first wrap is wrapped under tension around the concrete core and a portion of the cap to form a continuous water resistant barrier around the outer surface of the concrete core. A second wrap can be wrapped under tension around the inner surface of concrete core to form a continuous water resistant barrier around the inner surface of the concrete core. Structural body can be formed as a pipe with a male and female ends to interconnect multiple pipes. The joint formed between two structural bodies has a continuous water resistant barrier that prevents the environment from contacting the concrete core.

A duct board system/method utilizing extruded edge interconnection strips (EIS) is disclosed. The EIS are formed to allow linkage of planar duct board sheets (DBS) in a variety of connection methodologies including right angle corner connections (RAC), planar sheet connections (PSC), planar interface connections (PIC), and surface interface connections (SIC), without the need for specialized DBS cutting tools or fabrication dies. The EIS may incorporate provisions for spaced and/or on-demand fastener connection of DBS to the EIS, provisions for ridged/lobed/edged linkage of the DBS to the EIS, as well as provisions for edge sealed linkage of the DBS to the EIS.

A unitary support assembly for connecting an air transport duct to a support includes a body portion, a duct connecting means integrally formed with the body portion for selectively securing the support assembly to the air transport duct, and a support connecting means integrally formed with the body portion opposite the duct connecting means for selectively securing the support assembly to the support.

A mounting head (T) for mounting a pump or a valve on a neck (22) of a reservoir (2), the mounting head (T) having a mounting member (3) for imparting an axial mounting movement from an axial arrangement placed on the neck (22). The mounting member (3) has a centering mechanism (35, 36, 4) bringing the dispenser member (1) into an axial arrangement on the neck (22) if offset. The mounting head (3) has mounting tabs (31) movable axially so as to bring the dispenser member (1) from the axial arrangement towards the final position, and movable radially inwards so as to return the dispenser member (1) into an axial arrangement. An outer clamping collar (4) simultaneously moves the mounting tabs (31) radially inwards from a spaced-apart rest position.
