A coupler assembly kit and methods of use are described. Embodiments of the coupler assembly kit can be implemented to couple a corrugated pipe to a concrete section. Generally, the assembly kit can be implemented to couple a spigot end of the corrugated pipe to a bell end of the concrete section. In one embodiment, the coupler assembly kit can include a circumferential cable, a plurality of second cables having a threaded rod on end and an eye bolt on the other end, a plurality of linkage crosses, and a gasket. The coupler assembly kit can be assembled and implemented on location to connect a high-density polyethylene corrugated pipe to a reinforced-concrete flared end section.

The invention relates to a plug connection between two tubular workpieces (1, 2) which are made of concrete and each of which has an inner liner (5) made of plastic, one of which forms a tip end (3) and the other a socket end (4) receiving the tip end (3), wherein the inner liners (5) have circumferential sealing flanges (12) which cover the end face (13) of the tip end (3) or the socket face (14) and wherein a joint seal (16) is provided between the sealing flanges (12). In order to provide advantageous structural conditions, it is proposed that the inner liners (5) are provided with a circumferential elastomer angled profiled section (8, 9) at the end face, which receives the circumferential edge of the inner liner (5) in an end-face profiled groove (11) of its axially parallel limb (10) and whose limb at a right angle to the axis forms the sealing flange (12).

An assembly includes a first tube. The first tube includes a first end configured to receive a second tube. The second tube includes a first end configured to slidably translate into the first end of the first tube and to receive an insert. The insert is configured to be disposed within a first portion of the second tube that is near the first end of the second tube. The first tube, the second tube, and the insert form a seal. The coefficient of thermal expansion (CTE) of the first tube is similar to the CTE of the insert and different from the CTE of the second tube.

An apparatus and method for manufacturing glass objects comprising a glass blowing pipe and a metal mounting device configured to melt with glass to form a glass piece that is easily removed from the glass blowing pipe without the need to break the glass from the headstock of the glass blowing pipe, wherein the metal mounting device comprises a contact patch and a number of slits to secure the metal mounting device to the glass. A method for manufacturing a glass object utilizing a metal mounting insert is described. A glass object having a metal mounting insert for installation and use in other applications is also described.
