Centrifugally cast pipe

A centrifugally cast plastic pipe with no voids on the inner and outer surfaces visible to the unaided eye from bubble formation having a wall thickness ranging from about 1/4-inch to about 3 inches and an outer diameter ranging from about 2 inches to 12 feet, which is comprised of bulk-polymerized dicyclopentadiene.

A centrifugally cast plastic pipe with no voids on the inner and outer surfaces visible to the unaided eye from bubble formation, which contains fiber mat reinforcement and is comprised of bulk-polymerized dicyclopentadiene.

A centrifugally cast plastic pipe with inner and outer surfaces having less than one visible void to the unaided eye per square inch of surface caused by bubble formation having an outer diameter of from about 4 inches to about 12 feet, which is comprised of bulk-polymerized dicyclopentadiene.

A centrifugally cast plastic pipe with inner and outer surfaces having less than one visible void to the unaided eye per square inch of surface caused by bubble formation having an outer diameter in the range of 2 inches to 12 feet and a wall thickness ranging from about 1/4-inch to about 3 inches, which is comprised of bulk-polymerized dicyclopentadiene, wherein the pipe is produced by the process of centrifugally casting a reactive monomer formulation of bulk polymerizable monomer under a pressurized atmosphere.
