Going Tubular: A material used for pipelines in mines is finding broader applications Giant high-density polyethylene tubes are often used as pipelines for moving wastewater through mines. Their corrugated walls make them extremely sturdy and structurally independent, but they can also be adapted as a structural building material. They happen to be almost 100 percent soundproof, which is insignificant in their original application but offers a host of possibilities for other uses. The pipes were used in a temporary pavilion at Santiago’s Museum of Fine Arts, and plans now call for them to be cut in half and incorporated as roof elements in a permanent structure.
