Abstract
Plastic pipes, such as high density polyethylene plastic pipes, useful for distributing natural gas and which have improved impact resistance and burst strength. The plastic pipe has an inner and an outer surface, with the inner surface defining a channel for conveying natural gas and the like. A fabric overlies the outer surface, preferably in a helical wrap. The fabric is formed of high tenacity polyolefin fibers, preferably polyethylene and/or polypropylene fibers. The fabric provides the pipe with improved burst strength and impact resistance. The pipe can be used to transport natural gas under low pressure or higher pressures.
