Laminated Pipe
water, sewer, or gas pipe made of thicknesses of veneer or scale board successively wrapped to obtain thickness and strength. Each layer is thoroughly saturated with asphalt, and the grain of alternate layers passes in transverse directions, so as to secure an intimate bond and a line of resistance to disruption in any direction, lengthwise, oblique, or across the pipe circumference. The veneer is sometimes made to alternate with fabric or an adhesive composition.
