The present disclosure relates to an insert and system of installing the same. The insert includes a tapered core and a cylinder. The core releasably secures to an installation device which includes a depth stop or a depth control to control the installation depth of the insert. The insert may be provided in a tray that allows for easier handling of the inserts and installation thereof in installation holes, for example in a hydraulic manifold. In some cases, the core includes a threaded hole to releasably secure the insert to the installation device, thus allowing the installation device to pull the core into the cylinder. The core and cylinder may be made of metallic materials such as steels, steel alloys and others. In some cases the insert can withstand blow out pressures of 40,000 psi or higher.

A joining method for members includes: providing a steel component 10 including insertion holes 14a and 15a, an aluminum pipe 20 having a hollow shape, and a support component 30; inserting the aluminum pipe 20 into the insertion holes 14a and 15a of the steel component 10; and enlarging the aluminum pipe 20 through deformation and joining the aluminum pipe 20 to the steel component 10 by press-fitting. The press-fit joining is performed while at least part of the support component 30 is disposed in a press-fitting region.

Method of lining a tubular structure with a plastics liner pipe comprising the steps of: temporarily reducing an outside diameter of the liner pipe by passing the liner pipe through a roller system; cooling the liner pipe once its outside diameter has been reduced and applying a thermal restraint; transporting the liner pipe to an installation site remote from the roller system; removing said thermal restraint; and installing the liner pipe in said tubular structure at said installation site.

A high-pressure tube compression fitting/flared fitting for use in combination with a thick-walled tube and a connection body wherein a sleeve is in engagement with a thick-walled tube. The sleeve is generally cylindrically shaped with the exterior thereof coated and then etched. The sleeve includes a first and second sharp inner circumferential biting edges which interengage and bite into and through the exterior of the end portion of the thick-walled tube and into the wall portion of the end portion of the thick-walled tube without narrowing the passageway through the thick-walled tube. The process for making the fitting includes placing an end portion of the thick-walled tube into engagement with a tube engaging surface of a tapered generally cylindrical wall of a guide rod.

A method for locking an internally threaded end piece such as a head piece, a tail piece, an end or sealing nut to a mandrel for a down hole tool to obviate the need for pins, set screws, and the like, to provide a more robust assembly. In two embodiments the threaded end piece is locked to the mandrel in a swaging operation.

A plurality of additional fixture members placed outside a pipe member at a plurality of positions of the pipe member, where the plurality of fixture members are fixed, and a plurality of electromagnetic coils placed inside the pipe member at the plurality of positions of the fixed pipe member. In this state, a pulse current is applied to the plurality of electromagnetic coils located at a first joint, where the fixture member is joined to the outside of the portion where first and second pipe elements of the pipe member are fitted to each other, is swaged and fixed to the pipe member before an fixture member located at a second joint, wherein fixture member is joined to at least one of the first and second pipe elements at a different position, so the plurality of fixture members are swaged and fixed to the pipe member by electromagnetic forming.

A joining method for members according to the present invention includes: providing a steel component including insertion holes, an aluminum pipe having a hollow shape, and a support component; inserting the aluminum pipe into the insertion holes of the steel component; and enlarging the aluminum pipe through deformation and joining the aluminum pipe to the steel component by press-fitting. The press-fit joining is performed while at least part of the support component is disposed in a press-fitting region.
