The corrugated inboard ply (110), the first corrugated outboard ply (114), and a weld-through ring (150) are welded to the first collar (102) and the second collar (102). The second corrugated outboard ply (112) is not hermetically coupled to the first collar (102) or the second collar (103). The sensor (116) is communicatively coupled with the interstitial space (126).

An end product and system for connecting large aluminum tubular pipe segments into an Isolated Phase Bus comprising reducing the diameter (or increasing the same) of one end of a tubular segment and sliding it into (or over) the untreated end of an adjacent pipe or tubular segment, followed by a tubular and circumferential welding of the same. The outside or inside circumference of the connected segments are uniform from distal to proximal end of the overall length of the connected tubular segments. A structural integral, axially aligned, simplified set of connectable tubular segments allows for a grounded connection between power generators and step transformers. Preferably, the overall diameter change of the necked down flange (or outwardly flared flange) of one tubular segment is less than or only slightly greater than twice the material wall thickness of the tubular segment's initial pre-rolled flat aluminum sheet material.

Pre-manufactured pie cut pieces provide internal cutouts such that the cutouts from one piece are complementary to the cutouts of an adjacent piece so that the pieces connect by an interlocking friction fit. A series of pie cut pieces can be connected this way in concatenated fashion to produce a section of curved piping. The joints between the joined pieces can be sealed by welding or other suitable sealing means.

A pipe having a pipe element for conveying a medium in a flow direction and having a flange element for connecting the pipe element to a connection partner. The pipe element has a pipe body with a media passage opening for conveying the medium in the flow direction. The flange element has a flange body with a media passage opening for conveying the medium in the flow direction. The flange element is arranged at one end of the pipe element in such a way that the media passage openings at least substantially overlap. The pipe has a sensor element which is arranged in the flange body in such a way that at least a portion of the sensor element can be in contact with the medium.

A repaired turbine housing for use in an air cycle machine including a journal bearing bore having an inlet, an outlet, and an inner diameter of about 2.5800.001 inches (6.5530.003 centimeters). The repaired turbine housing including a cylindrical insert secured within the journal bearing bore. The cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The cylindrical insert being inserted into the inlet of the journal bearing bore up to the step. The step has an outer diameter greater than the outer diameter of the cylindrical insert. The inner surface of the cylindrical insert includes at least one selected inner diameter.

A connector device for a fluid system for medical purposes is disclosed that includes a main housing having a fluid flow chamber forming two channel portions leading in different directions towards two open attachments, wherein the attachments are provided for connection to a fluid line or a fluid reservoir, and with an attachment port which opens into the fluid flow chamber and which has a closure arrangement and which includes a Luer connecting portion. The fluid flow chamber has a dimensionally stable flow-guiding wall which is arranged between the two channel portions in the fluid flow chamber and protrudes freely with a front edge towards the attachment port in such a way that the closure arrangement, upon opening of the closure arrangement, interacts with the front edge of the flow-guiding wall in order to effect flow of fluid out of the attachment port into only one channel portion.

A method for repairing a turbine housing of an air cycle machine that includes removing damaged material from a journal bearing bore of the turbine housing and forming the journal bearing bore. Next, the inner diameter of the journal bearing bore is determined and a cylindrical insert is formed. The cylindrical insert includes a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The second end of the cylindrical insert is inserted into an inlet of the journal bearing bore up to the step. The cylindrical insert is secured to the turbine housing and both are stress relieved by heating. Following the stress relief, the inner surface of the cylindrical insert is formed and seal grooves are formed on the inner surface.

The invention relates to a method of manufacturing a pipe segment for a link tube between the sea floor and a petroleum drilling rig disposed on the sea surface, wherein it consists in: providing a transport pipe segment that is resistant to open-sea conditions; disposing a female bayonet-piece around one reinforced end of the transport pipe segment; welding or otherwise bonding a narrower portion of the bayonet-piece to said reinforced end; disposing an insulator around the transport pipe segment and around the bayonet-piece; inserting the transport pipe segment into an outer wall segment; welding or otherwise bonding a narrower portion of the outer wall segment to the other reinforced end of the transport pipe segment; disposing a cover-piece around the bayonet-piece; welding or otherwise bonding the cover-piece to the outer wall segment and to the bayonet-piece; it being possible to apply tightening torque to the outer wall segment and to transmit it to the transport pipe segment.

The invention relates to a system for connecting rigid pipes and for connecting flexible pipes. The pipes have corresponding outer diameters, with a press jaw having a press contour, with at least one first fitting for press-fitting to a rigid pipe, the at least one first fitting having a first press sleeve with a first outer contour, with at least one second fitting for press-fitting to a flexible pipe, the at least one second fitting having a second press sleeve with a second outer contour, the at least one second fitting having a second press sleeve with a second outer contour has a second press sleeve with a second outer contour, the outer contour of the first press sleeve and the outer contour of the second press sleeve in each case being adapted at least in sections to the press contour of the press jaw of the press jaw and can be pressed by the press jaw and wherein the outer contours of the first press sleeve and of the second press sleeve correspond at least in sections. This system solves the technical problem of simplifying the on-site effort for installing piping systems. In particular, the task is to specify suitable combinations of fittings for rigid and flexible pipes
