摘要： A multi-layer tube for use in a motor vehicle system to transport fluids containing hydrocarbons such as would be found in a fuel line, a vapor return line or a vapor recovery tube having a first layer radially disposed innermost made up of an extrudable melt-processible thermoplastic material capable of withstanding prolonged exposure to automotive fuel and various fuel additives, and second layer made up of an extrudable, melt-processible non-polyester, non-alcoholic thermoplastic material capable of sufficiently permanent laminar connection with the first layer so as to prevent delamination between the first and second layers during a desired lifetime of the tube. The thermoplastic material of the second layer is made up of at least one constituent which is chemically dissimilar from the thermoplastic material employed in the first layer such as a melt-processible compound having at least two isocyanate groups in combination with a compound which is chemically similar to the thermoplastic material of the first layer such as a thermoplastic elastomer, or a polyamide. The tubing of the present invention may, optionally, include additional layers interposed between the respective layers or may include additional layers which overlie the exterior surface of the second layer.

摘要： A method of connecting a resin hose to a metal pipe comprising the steps of: forming a fluororubber coating layer on an inner peripheral surface of the resin hose; forming a lubricating layer of a fluorine-containing lubricant on an inner peripheral surface of the fluororubber coating layer; and inserting an end portion of the metal pipe into an end portion of the resin hose formed with the lubricating layer. Fluorine atoms in a fluororubber molecular skeleton are hydrogen-bonded to hydroxyl groups introduced in a metal of the metal pipe and therefore the adhesion between the resin hose and the metal pipe is enhanced for improvement of the sealing property. Further, the lubricating layer facilitates the insertion of the metal pipe into the resin hose for the connection therebetween.

摘要： A conduit pipe is installed within a cable tunnel and telecommunication cables are disposed in the conduit pipe. The conduit pipe is divided longitudinally into a plurality of divided bodies. Each divided body is equipped at one longitudinal side with a retaining part and at the other longitudinal side with a protruded part. A single conduit pipe is formed when the divided bodies are connected to each other along the longitudinal side. Since the divided bodies can be wound around a small-diameter bobbin to be carried, the space for their custody is reduced and the carriage thereof is easier. Further, since connection parts on surfaces of the conduit pipes can be arranged such that they occupy empty spaces between conduit pipes, the space occupied by the connection parts can be minimized, thereby comparatively larger number of telecommunication cables being able to be disposed within the cable tunnel.
摘要翻译：导管安装在电缆隧道内，电信电缆设置在导管中。导管被纵向划分为多个分开的主体。每个分开的主体在一个纵向侧面具有保持部分，并且在另一个纵向侧面具有突出部分。当分割体沿着纵向侧彼此连接时，形成单个导管。由于分割体可以卷绕在要携带的小直径线轴上，因此保管的空间减小，并且其滑动更容易。此外，由于导管的表面上的连接部分可以布置成使得它们占据管道之间的空的空间，所以连接部分占据的空间可以被最小化，从而能够将较多数量的通信电缆布置在电缆内隧道。

摘要： The present invention provides a multilayer tube comprising (a) a first outer thermoplastic layer and (b) a second inner thermoplastic diffusion barrier layer which is directly bonded or fused to the first layer by a material-to-material bond. The second layer has a thickness of from about 0.1 to about 0.6 mm. At least one layer of the multilayer tube has an elongation value at break of at least about 130%. Also, at least one layer of the multilayer tube includes a heat stabilizer. The multilayer tube of the present invention is able to withstand 1,000 hours or more of contact with fuels without the layers delaminating. Furthermore, the multilayer tube is able to withstand 1,000 hours or more in an antifreeze mixture of 5 to 50 percent by volume of methanol in water at from about −20 to about 80° C. without the layers delaminating. The multilayer tube of the present invention does not require an intermediate bonding or primer layer to join the thermoplastic layers. Additionally, the multilayer tube does not delaminate after prolonged contact with fuel, oil, and antifreeze or heating and cooling. The multilayer tube may be used in motor vehicles as a fuel line or a vapor return or recovery line.
