Abstract: Electric welding coupler for the welding of pipes made of thermoplastic material or other weldable plastics comprising a cylindrical body made of thermoplastic material or other weldable plastics, containing at least one welding element, wherein the welding element is arranged close to the inner diameter of the cylindrical body, wherein the welding element forms at least two welding zones, a contact for feeding the electric current and at least one cavity, wherein the cavity is arranged in the cylindrical body, wherein a reinforcing ring is arranged around the outer circumference respectively outer diameter of the cylindrical body.

Abstract: A pressure-rated joint includes a first pipe including a bell, and a second pipe including a portion that is disposed within the bell of the first pipe. A mechanical coupling and a chemical coupling are provided between the first pipe and the second pipe.

Abstract: The present invention is a composite laminated sheet material suitable for structures such as containment sumps. The laminated material comprises a fabric-backed thermoplastic layer upon which thermoset plastic is applied to the fabric side. The thermoplastic layer is formed by contacting a layer of fabric onto a layer of molten thermoplastic such that the liquid thermoplastic permeates a portion of the fabric layer to form a mechanical bond with the fabric layer when the thermoplastic layer cools and hardens. Thermoset plastic, such as fibreglass resin, is sprayed onto the fabric side of the thermoplastic layer to allow the liquid resin to permeate the fabric layer. Once the resin cures and hardens, the fabric layer is mechanically bonded to the cured thermoset plastic layer to effectively bond the thermoplastic layer to the thermoset plastic layer.

Abstract: The coupling for connecting a tube (2) to a commercially available mixer or mixer accessory comprises an adapter (3) and a fastening piece (4), the adapter being provided at one end with an insertion portion (8) and at the other end with a receiving portion (12), and the fastening piece being pushed over the adapter. A coupling of this type allows the secure and simple use of capillary tubes, e.g. for medical technique.

Abstract: A hose joint assembly includes a fitting, a hose receivable onto the fitting, and an adhesive for bonding the hose and the fitting together. For example, the adhesive is a microencapsulated two-part epoxy adhesive that functions as a lubricant when assembling the hose onto the fitting before curing.

Abstract: Pipes and pipeline components made of plastic or PVC, which are designed to be assembled into pipelines used to convey water in structures, and which have one bore located on the side, near each end of the pipeline components. After assembling the pipeline in the designated wall, the pipes and pipeline components are glued together by injecting liquid acetone into the bores, causing the pipes and pipeline components to adhere to one another and to become sealed.

Abstract: A tubular subsea mechanical joint having a first tubular member. The first tubular member has a bell end disposed a first tubular body; the bell end comprises a central axis and an interior sized to form an interference fit with a pin end disposed on a second tubular body of a second tubular member.

Abstract: A connector for a fuel tank includes a flange portion, an outer connecting portion to be connected to a pipe member and an inner connecting portion to be inserted into a fuel tank through a connecting opening of the fuel tank. The inner connecting portion has an engaging portion to be engaged with an engaged portion provided to a member when the member is to be disposed in the fuel tank. The flange portion includes an outer flange member made of a synthetic resin same as that of an outer surface of the fuel tank, and an inner flange member made of a synthetic resin having a gas barrier property and a rigidity higher than that of the synthetic resin constituting the outer flange member. The inner connecting portion and the inner flange member are made of the same material.

Abstract: A pipe joint connecting a pipe using an anaerobic adhesive, which possesses a double pipe structure formed with an inner pipe fitting into the inner circumference side of the end of the pipe, and an outer pipe fitting into the outer circumference side of the end of the pipe, integrated with a gap between them, and a tapered surface formed with at least one or the other of the inner piper or outer pipe approaching the other; and a pleated O-ring provided on the end of the outer pipe to set the pipe in place by tightening an O-ring locking material supported by the outer pipe.

Abstract: An insert section of an insert member is inserted into a tube member in a state in which the insert member is detached from a recess to form a diametrally expanded section on the tube member. Subsequently, the insert member is fitted to the recess to install the tube member to the recess. At this stage, an outer circumferential surface of an expanded section of the insert member tightly contacts with an inner circumferential surface of the recess to effect the sealing function. Subsequently, a tapered section and an outer circumferential surface of the tube member are resin-welded by using a welding material. Thus, the tube member is prevented from disengagement from a body.

Abstract: A fuel tank connector A for connecting a fuel tank B and a pipe C in communicating fashion includes a gas barrier member 10 made of a synthetic resin and having a gas barrier property. The gas barrier member includes a tubular portion 11 and a flanged portion 12 provided on a peripheral side of the tubular portion 11 and having a greater side than an opening Ba of the fuel tank B. The gas barrier member 10 is made of polybutylene terephthalate, polyphenylene sulfide, a liquid crystal polymer, aliphatic polyketone, aromatic polyamide, a blended polymer of an ethylene-vinyl alcohol copolymer and high-density polyethylene, a blended polymer of polyamide and polyethylene, a blended polymer of polyamide and high-density polyethylene, or polyethylene terephthalate.
