A load introduction device and a method for adhesive bonding of a load introduction device for fiber composite materials is disclosed. A sealant, particularly a first adhesive is used in the creation of a cavity and in the creation of a secured arrangement for the injection of adhesive into the cavity.

The present disclosure relates to a housing having an interior and an exterior. The housing includes a first housing piece and a second housing piece that are coupled together by a joint. The joint includes a bonding material and the joint is configured such that when the bonding material is pressurized during formation of the joint the bonding material is predisposed to move toward the interior of the housing as compared to the exterior of the housing.

A pipe adapter includes a first tubular element, a second tubular element, and an annular securing member disposed around and fixed to a second portion of the first tubular element. The annular securing member has a flange portion that contacts and secures the second tubular element axially relative to the first tubular element while also allowing the second tubular element to rotate relative to the first tubular element and the annular securing member. An annular sealing member is located around the first portion of the second tubular element to provide an axial seal along the adapter.

A pipe coupling construction which can be used for coupling of a high-pressure pipe includes an inner bush of a non-metallic material and an outer bush, which bushes in axial section have parts which mesh with each other in order to transmit axial forces. The inner bush can be fused or adhered to an outer cover layer of the pipe. The coupling has a metal sleeve construction. The outer bush has an outer bush protruding end which protrudes with respect to the inner bush and the metal sleeve construction is at least partially located within the outer bush protruding end. The metal sleeve construction and outer bush in axial section have parts which mesh with each other.

A method and apparatus for attaching a branch polymeric fitting to a host polymeric pipe in which a flexible heating blanket is inserted between and used to heat the respective branch and host pipe surfaces. When the parts reach the appropriate temperature, the pipes are separated a small distance and the heating blanket is removed. The branch fitting and host pipe are then fused by placing the heated pipe ends in contact and applying pressure.

A battery assembly, such as a bipolar battery assembly, generally includes a first casing portion comprising an optically-absorbing region, and a second casing portion comprising an optically-transmissive region. The first and second features form a welded joint. Fabrication of such an assembly can include physically mating the first casing portion with the second casing portion, and irradiating, such as using a laser, the optically-absorbing region defining the first feature through the optically-transmissive region to form the welded joint.

Flange connection for connecting two pipeline ends made of plastics material and method for assembly, containing two mutually opposing pipe ends (2) made of plastics material, wherein the pipe ends each have a prewelding neck, two loose type flanges, wherein a loose type flange is arranged at each pipe end, wherein the loose type flanges have holes for mutual clamping, clamping means, wherein the clamping means are arranged in the holes and serve to mutually pull together the loose type flanges and the pipeline ends, and a sealing element, wherein the sealing element comprises a conductive plastics material and exclusively one material.

A system for coupling pipes includes a first pipe having a tapered, spigot end; a second pipe having a tapered, spigot end; and a coupler having two tapered socket ends adapted to internally receive the respective tapered, spigot ends of the first pipe and the second pipe. The first pipe and the second pipe are made from a reinforced thermosetting resin (RTR). The coupler comprising a resistive element implanted therein and connected to electrodes extending to an exterior of the coupler. A thermoplastic material is disposed between an exterior of the first pipe and an interior of the coupler. A thermoplastic material is disposed between an exterior of the second pipe and the interior of the coupler. Upon application of electricity to the electrodes, the resistive elements are heated sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler. A method of coupling pipes includes disposing a thermoplastic material between an exterior of a first pipe and an interior of a coupler; disposing a thermoplastic material between an exterior of a second pipe and the interior of the coupler; inserting the first pipe and the second pipe into the coupler; and applying of electricity to electrodes of the coupler such that resistive elements of the coupler heat sufficiently to melt the thermoplastic material such that, when the heat is removed, the hardened thermoplastic material seals the first pipe and the second pipe to the coupler.

A fitting or connector for use in constructing a tubing assembly is made by bonding an olefin gasket to an end face of a polypropylene fitting member. The gasket is bonded to the fitting member via a heat fusion technique that causes localized melting together of the gasket and the fitting and generates a composite fitting or connector.
