Abstract

255,970. Perman, P. E. May 6, 1925. Corrosion, preventing.-In a water-pipe joint comprised of pipe &c. elements 2, 3, Fig. 1, of different metals, corrosion due to galvanic action, is eliminated by interposing nipples 1 of electrically non-conducting material, such as fibre, between the parts to be connected, said nipples simultaneously acting as insulators and connecting members. In the modification shown in Fig. 4, bottom washers are used for insulating the ends of the pipes, while the nipples 1 may be provided with threaded sleeves of the same metal with which it is to be connected.
