摘要： A seam welded steel pipe proofed against corrosion and prevented from oxidizing a fluid such as gasoline to be passed therethrough is produced by a process comprising forming an Ni layer by electroplating on at least one of the opposite surfaces of a steel strip, abutting the opposite edges of said steel strip in the direction of width with the Ni layer on the inside and fusing the abutted edges, subjecting the resultant steel pipe to a heat treatment in an oxidizing atmosphere thereby forming an oxide coating on the surface of the Ni layer, acid dipping the resultant steel pipe thereby removing the oxide coating from the portion of the skin of steel exposed in the neighborhood of a bead part in consequence of the fusion, and introducing a chemical Ni plating liquid through the interior of the steel pipe thereby coating the inner surface in the neighborhood of the bead part with a Ni alloy layer by chemical plating.

摘要： A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine is provided. The assembly comprises an elongate conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. Outer walls of the conduit include at least one flat or arcuate flexible first absorbing surface, which is smoothly and integrally connected to an arcuate second absorbing surface. The first absorbing surface or the second absorbing surface faces fuel inlet ports of the sockets. The sectional configuration of the conduit can be flat, a telephone receiver shape, a character “T” shape, a corrugation shape, a dumbbell shape or a reverse eye mask shape. Thus, fuel pressure pulsations and shock waves are reduced by abrupt enlargements of fuel passages and bendings of the absorbing surfaces.
