摘要： A pipe coupling for triple wall corrugated plastic pipe includes a triple wall corrugated bellmouth connector that is of a unitary construction with one end of the corrugated plastic pipe. This bellmouth connector is of higher strength and in cooperation with the two wall corrugated spigot provides a high strength coupling. This coupling includes the bellmouth connector and spigot that are made inline with the corrugated pipe. A method for the manufacture of the pipe includes controlling of an air pressure on the outside of a formed two wall corrugated pipe as an exterior third wall is secured thereto.

摘要： A plastic drain pipe for drainage includes a first end, a second end, and a pipe sub-section between the first end and the second end. The pipe sub-section includes a collapsible section of corrugated pipe, a first non-collapsible section of corrugated pipe, and a second non-collapsible section of corrugated pipe. The collapsible section of corrugated pipe has a first joining area and a second joining area. The first non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the first joining area, and the second non-collapsible section of corrugated pipe is connected to the collapsible section of corrugated pipe at the second joining area. An outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section of corrugated pipe and an outermost diameter of the second non-collapsible section of corrugated pipe.
