    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: The invention is a well pipe with longitudinal rods arranged in intervals in the pipe wall over the whole circumference. It is characterized by the fact that the well pipe is made of polymer concrete, and of an additional layer of packed gravel functioning as a filter if designed as a well filter pipe, and that the rods are glass fiber rods which transfer axial tensile load.
