A method of retrofitting an environmental control system of an aircraft includes inserting the orifice plate through the connector slot and the connector ring slot into the receptacle. The method also includes aligning the covering portion with the connector slot.

This invention provides for a hand-held clamping tool to position and hold two pipe flanges in place allowing for the alignment the bolt holes and the gasket that in placed between the pipe flanges by using an alignment spike; and then holding the pipe flange and the gaskets in place while bolts are installed to join the two gasket sections together. The invention also has a detachable alignment spike and a also has a calibration mark on the alignment spike. The invention also describes a tool for positioning and holding ISO flanges.

A connection apparatus suitable for mounting on a structural element and connection to a port of a system or component in which the connection apparatus comprises a connector, a flange and a compressible biasing means is provided. The connector forms a longitudinally extending conduit having an axis (A) extending along the centre of the conduit, a port end adapted to be engaged with the port of a system or component, and a second end. The connector comprises a shoulder extending around the perimeter of the connector, and the shoulder extends around the perimeter of the connector in a direction substantially perpendicular to the portion of the conduit axis (as) around which the shoulder extends. The biasing means is adapted to at least partially extend around a portion of the connector adjacent to the shoulder.

Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system has at least one retaining clip having a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each having at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.

A clamping system for connecting a first and a second tube whose opposite ends have clamping surfaces protruding from the cylindrical outer surface of the tubes. The system includes a collar having a belt able to be clamped around the clamping surfaces. The belt includes a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an external retaining device having a retaining bar, which protrudes axially from the first flank while being oriented transversely to the axis of the collar and which has a transverse retaining ridge, the bar being able, from a rest situation in which the retaining ridge projects towards the axis of the collar relative to the edge of the first flank in the unclamped situation of the collar, to be elastically deformed to space the retaining ridge away from the axis of the collar.

A pig trap of this disclosure may include one or more injectors or nozzles located along a sidewall of the barrel and oriented to deliver a jet of fluid toward a back side of a vertical member of a pig or tool. The nozzle may be part of an assembly that includes a longitudinally extending pipe having a flat-profile flange at an inlet end, a curved-profile flange at the nozzle end, and a bend in between the two ends. When the assembly is installed in a sidewall opening of a pig trap, the nozzle delivers a jet of fluid toward the back side of a vertical member of the pig. A leak path may be provided through flanges or formed between the sidewall opening and a periphery of the curved-profile flange. Launch forces of more than 10 to 15 times that of a conventional launcher may be achieved.

A conduit joint system securing ends of two conduits together includes first and second conduits having first and second flared ends and first and second liners protruding from the flared ends. The liners are joined together so that the flared ends are opposing and spaced from one another and portions of the liners are between the flared ends. An external coupler is configured to receive the flared ends and includes (i) a first flange receiving portion configured to receive the first flared end, (ii) a second flange receiving portion configured to receive the second flared end, and (iii) a body portion extending between the flange receiving portions and configured to receive the portions of the liners between the flared ends. With the liners joined together and with the external coupler receiving the flared ends, and the portions of the liners, the external coupler secures the first and second conduits together.

A unitary steel bracket has an arced portion and a hanger appendage extending perpendicularly from a convex perimeter of the arced portion. The arced portion has two opposed planar surfaces with parallel mount holes through each end. The hanger appendage has two opposed planar surfaces coplanar with the arced portion planar surfaces. A portion of the hanger appendage is bent at a 90-degree angle and has a support mount hole perpendicular to the parallel mount holes. the bracket is prefabricated to a predetermined bracket size corresponding to a predetermined pipe flange size. A method of hanging joined flanged includes providing the bracket; aligning the parallel mount holes with holes on a pipe flange; inserting connection bolts through the holes; threading nuts onto the bolts to a predetermined torque; and attaching the support mount hole to a building structure.

A mounting assembly including two end pieces whose ends are able to be fitted along an axis and a mounting belt disposed around the second end piece in a pre-mounted configuration before the fitting of the first end piece by an opening delimited by a first edge of the belt. The end pieces have respectively a first and a second centering surface able, in the fitted state, to axially overlap and to come into contact to limit the relative clearances of the end pieces. The belt carries a retaining lug which extends outside the belt. In the pre-mounted state, the end pieces are retained in the fitted state by the combination of contact of the centering surfaces and cooperation of the free end of the retaining lug with a bearing surface of the first end piece located on the side of the first edge of the belt.

A device is for operation on a pressurized bolt connection between a first flanged tubular and a second flanged tubular. The device has a first clamping member with a first contact portion adapted to bear against the flange of the first tubular, a second clamping member with a second contact portion adapted to bear against the flange of the second tubular, and a connection arrangement for pulling the first clamping member and second clamping member together. The first contact portion and the second contact portion are adapted to bear at an inner part of the flanges between the bolts of the bolt connection and the body of the two tubulars.
