摘要

When polyethylene (PE) pipes were first introduced to gas distribution in the late-1960s, they offered a significant upgrade in terms of cost efficiency, durability and ease of installation.Since then, PE pipes have come to dominate the landscape of gas distribution systems. In the United States and Canada, more than 90% of natural gas distribution systems use PE pipes in their installations. PE pipes are also used in a majority of installations in Australia and are increasingly used in pipelines around the world.The advantages of PE pipes in gas distribution are clear when compared with traditional metal piping systems. Unlike metal pipes, PE pipes are not susceptible to corrosion or rust, and they are extremely resistant to cracks caused by environmental stresses. As PE pipes are lightweight, flexible and easy to store, installation and maintenance of distribution systems is simplified dramatically compared to metal piping. PE pipes require less energy to manufacture than metal pipe products and their superior longevity makes them more cost-efficient.
