The present invention relates to a novel locking hose clamp device. The device is designed to function as a locking nut and remain tight. The device comprises a lock washer and an insert component. The device can be applied to a clamp and secured with a screw. The insert component is positioned around the screw, such that the screw is threaded into the insert component. The locking washer is secured around the screw, behind the head of the screw. When the user tightens the device, the screw threads catch onto corresponding threads within the insert component. The screw is threaded into the insert component and tightened down, such that the head of the screw contacts an edge of the insert component. The locking washer is then compressed which causes the screw to lock in place.

A sprinkler configured for engagement with a coupling, the sprinkler includes a raised lip end, the sprinkler defining a raised lip at the raised lip end; and a deflector end disposed opposite from the raised lip end, the sprinkler defining a groove between the raised lip and the deflector end.

Disclosed is a pipe coupling or a pipe clamp which has an outer clamp band with an outer longitudinal slot, an inner clamp band with an inner longitudinal slot and a tensioning mechanism arranged on the outer clamp band. The inner longitudinal slot is offset in relation to the outer longitudinal slot. A separate flat spanning element is provided on the inner clamp band in order to span the inner longitudinal slot. The spanning element extends from one side of the inner longitudinal slot towards the other side of said longitudinal slot.

A method of installing a coupling for joining pipe elements uses a pipe coupling having two segments with action surfaces in facing relationship. Attachment elements on each segment, in the form of lugs, accommodate adjustable fasteners which draw the segments together when tightened. Support surfaces on the lugs engage one another and react the fastener force. Stop surfaces are positioned on the lugs adjacent to the support surfaces. Engagement between the stop surfaces provides a visual indication that the coupling has been properly installed.

A fire suppression sprinkler adapted to receive arcuate surfaces of a grooved coupling is retainable to the coupling in a pre-assembled state. The coupling joins the sprinkler in facing axial end to end relation directly to grooved pipe. The sprinkler has a monolithic body which defines a bore having an inlet and an outlet. A groove, positioned between the inlet and the outlet extends around the body. A projection, positioned between the groove and the outlet also extends around the body.

A riser support assembly includes a riser support pipe comprising a sidewall defining a first end, a second end opposite the first end, and an intermediate portion extending therebetween, the intermediate portion configured to extend through an elevated support structure; and a mount extending from the sidewall, the mount configured to engage a mounting surface of the elevated support structure to support the riser support assembly on the mounting surface.

A pipe coupler for coupling pipes of different kinds with a one or more crown partially flexible heads, integrated into the ends of the pipe coupler for accommodating grip rings and seals for coupling pipes of different kinds. The crown heads have planes at different levels that form grooves for accommodating the seals, and a backward trimmed cone-shape inner surface plane and flat plane for locking the grip rings inside corresponding recesses in the crown head. The external surface of the grip rings is also cone-shaped that corresponds the shape of the inner surface of the crown head and in friction contact with this inner surface. The grip ring blocks the seal from slipping out, and has sets of teeth for engaging with and locking to a pipe inside the coupler. Clamp bands wrap around the external surface of the crown heads that yield against it, thereby tightening the grip of the teeth in the pipe as internal pressure increases inside the pipe and causes the grip ring to axially travel towards the proximal end of the crown head. All parts of the coupler are made of synthetic materials and thereby avoid corrosive processes.

An insulated exhaust gas conduit system includes a first exhaust gas conduit, a second exhaust gas conduit, a first insulation sleeve, and a second insulation sleeve. The first exhaust gas conduit has a first exhaust gas conduit end portion. The second exhaust gas conduit has a second exhaust gas conduit end portion that is configured to engage with the first exhaust gas conduit end portion. The first insulation sleeve comprising includes a first insulation sleeve and a first insulation sleeve heat shield. The first insulation sleeve insulation layer is disposed around the first exhaust gas conduit. The first insulation sleeve heat shield is disposed around the first insulation sleeve insulation layer. The first insulation sleeve extends beyond the first exhaust gas conduit end portion. The second insulation sleeve includes a second insulation sleeve insulation layer and a second insulation sleeve heat shield.

A corrugated band clamp is configured to effectively secure a sleeve around a pipe. The corrugated band clamp comprises an elongate member having a first lateral side and an opposing second lateral side. Typically, at least a portion of the length of the elongate member comprises a corrugated portion and at least a portion of the length of the elongate member comprises a non-corrugated portion. The corrugated portion of the elongate member enables the corrugated band clamp to effectively secure sleeves on pipes with non-parallel surfaces. In addition, applications of the corrugated band clamp system, methods of manufacture and methods of use are provided.

A pre-assembled pipe coupling includes a gasket, a housing surrounding the gasket, and a fastener. The housing has three segments sequentially coupled to each other to define an insertion boundary. A bridge segment has a first mount extending lateral from the wall and having a plurality of first lateral walls defining a first aperture and a second mount having a plurality of second lateral walls defining a second aperture. A first clamp segment has a first hook disposed in the first aperture. A second clamp segment has a second hook disposed in the second aperture. The fastener is disposed through the first fastener aperture and the second fastener aperture. The fastener has an adjusted length at which the first clamp segment grips the gasket, and the second clamp segment grips the gasket to locate the first sealing lip and the second sealing lip within the insertion boundary.
