    摘要： A method of repairing a polyolefin structure at a damaged area thereof containing applying a filler material as necessary to fill the damaged area, overlaying the filled damaged area with a transitional film having a first side adapted to bond to polyolefins, bonding the transitional film to the polyolefin structure, and applying a reinforcement system over the transitional film. The bonding of the transitional film to the polyolefin structure comprises applying heat to the transitional film.A repair system for repairing a polyolefin structure containing optionally a filler material on the polyolefin structure, a transitional film applied over and bonded to the polyolefin structure having a first side adapted to bond to polyolefins, and a reinforcement system, applied over the transitional film. The reinforcement system contains a fiber-reinforced polyurethane system bonded to the second side of the transitional film.

    摘要： End connectors of filament wound tubes are disclosed. The end connector uses an upset region at an end of the filament wound tube as a base for mounting a threaded ring around the tube. The ring is threaded to a sleeve mounted also around this upset region. The sleeve threads to a coupling on the other side of the upset region. The coupling carries means for connecting the filament wound tube to another body. In forming the end connector, the sleeve and coupling are assembled about the upset region and the ring, assembled on the body of the filament wound tube on the other side of the upset, is threaded to the sleeve.

    摘要： A substantially cylindrical coupling sleeve for producing a connection capable of resisting a tensile force between asbestos-cement pipes connected thereby comprises a carrier body portion of glass fiber roving cloth embedded in synthetic resin, with the maximum tensile strength oriented in the longitudinal direction of the sleeve. In the end regions, between a respective end face and an adjacent internal peripheral groove which co-operates with a groove on the pipe to accommodate a cable-like connecting member, the carrier body portion is externally wound with glass fiber rovings embedded in synthetic resin, with the maximum tensile strength oriented in the peripheral direction of the sleeve. The carrier body portion is of a cylindrical configuration with end regions which taper down to a reduced diameter. The internal peripheral groove is defined at the side towards the adjacent end face of the sleeve, in the region of the external winding therearound, by a lining layer of wedge-shaped cross-section and comprising glass fiber roving material embedded in plastic material with the maximum tensile strength oriented in the peripheral direction.

    摘要： A structure at a connection where at least two resin pipes are connected to each other end-to-end. The structure is characterized by annular resin body means provided on the inner periphery of the end of at least one of the resin pipes and having at least one end positioned in an annular recessed portion formed in the inner periphery of said one resin pipe. Since the above-mentioned end (which is more subject to the action of internal fluid than the other end) is positioned in the annular recessed portion, the resin body means is not eroded by the internal fluid.

    摘要翻译： 在至少两个树脂管彼此端对端连接的结构。 该结构的特征在于设置在至少一个树脂管的端部的内周上的环形树脂体装置，并且至少一端位于形成在所述一个树脂管的内周中的环形凹部中。 由于上述端部（内部流体的作用比另一端更为受力）位于环状凹部内，所以树脂体装置不被内部流体侵蚀。
