    • An engineering method of providing a lining onto the internal face of conduits for gas, city water, etc. that are buried underground. This lining work shall entirely be done from the portions exposed above ground. The distance of the supply pipe to the service tee is measured. The lining tube is set to a length that is slightly longer than this distance. The lining tube is turned inside out inside the supply pipe. As a result, a slightly longer length of non-reverse portion is left inside the supply pipe by the service tee. This non-reverse portion is helpful when cutting the rewinding tape that is tied to the lining tube after the insertion of a cutter. Next the heating tube shall be reversed similarly, and a hot water hose is inserted for circulating hot water in the heating tube. The aforesaid lining tube coated with the thermosetting adhesive is bonded onto the internal face of supply pipe. Next the heating tube is pulled out and the rewinding tape of the lining tube is cut and removed. A fusion-cutting heat rod is inserted for fusion-cutting the tip of lining tube for an opening. Then the fusion-cutting heat rod is pulled out.

    • A low cost and mass-producible fire protection zone penetrating member is provided which can be set on piping or the like with a one-touch operation as well as a method of injection-molding the fire protection zone penetrating member. One expanding slot is provided on a cylindrical body made from thermally expanding graphite, thermally expanding rubber, or thermally expanding resin as a main ingredient thereof. The slot extends in a longitudinal direction. A piping inlet section is formed at an entrance of the expanding slot so that piping can be set in or taken out from inside the member by means of a one-touch operation. The fire protection zone penetrating member has the configuration as described above and is manufactured with an injection molding machine. The cylindrical body as a main body of the fire protection zone penetrating member may have an oval cross section, so that the fire protection zone penetrating member can be applied to piping having a diameter in a wide range. With this feature, a number of required types of the product can be reduced with the unit production cost lowered.
    • 提供了一种低成本和大规模生产的防火区穿透构件,其可以一次性操作设置在管道等上,以及注射成型防火区穿透构件的方法。 一个膨胀槽设置在由膨胀石墨,热膨胀橡胶或热膨胀树脂作为其主要成分制成的圆筒体上。 槽沿纵向方向延伸。 管道入口部分形成在扩张槽的入口处,使得可以通过一触式操作将管道设置在构件内部或从构件中取出。 防火区穿透构件具有如上所述的构造,并且由注射成型机制造。 作为防火区穿透构件的主体的圆筒体可以具有椭圆形截面,使得防火区穿透构件可以应用于具有宽范围的直径的管道。 通过此功能,可以降低产品的所需类型,降低设备生产成本。
