摘要： A method for creating lengthwise extending lengths of pipe having an undulating or helical configuration symmetrically formed about a centerline of the pipe includes the steps of heating a sheet of material, feeding the sheet progressively to a succession of stamping stations at which an undulating shape is progressively imparted to the material until at the final station the desired final configuration is achieved in a lengthwise extending half section of the finished pipe, and securing one half section of pipe to another half section of pipe along lengthwise extending edges thereof to form the finished pipe. The undulating pipe of helical configuration finds particular use in the formation of pipelines intended to convey slurries of material such as bituminous material mined from oilsands. Apparatus for carrying out the method is also provided.
