Abstract
A spirally corrugated pipe elbow according to the present invention is constructed in such a manner that after a bend forming portion of a pipe body P having a given length and including a spirally corrugated pipe wall , with a partial portion a of the pipe wall existing in the peripheral direction of the pipe body P left uncut, is cut and removed from the pipe body P in the form of a cut portion having a substantially V-like shape when it is viewed from the side surface side thereof, the thus obtained two cut surfaces are then bent and contacted with each other with the uncut pipe wall portion a set on the large diameter side, and the thus contacted portions t are connected together in a watertight manner using connecting material m. Accordingly, it is possible to provide an elbow having a structure free from the above water leakage and a method capable of manufacturing such elbow easily and quickly.
