Abstract:

Methods for producing improved pipe structures for natural gas distribution pipelines produce a thin fibrous jacket or layer which can inhibit and prevent cracks in natural gas distribution piping by preventing surface scratches as well as by enhancing the pipe strength. Thermoplastic fibers are preferred in accordance with methods and structures of the present invention to facilitate the use of joining techniques and hot-tapping techniques common in the natural gas distribution industry. Non-woven, heat shrinkable fibers are also employed in sleeve structures to produce a protective fibrous jacket or layer.
