Plastic piling

Article Abstract:

Composite plastic-and-steel pipes pose potential benefits in terms of increased durability and corrosion resistance in marine settings. The piles, which are made up of steel pipes enclosed by recycled plastic, are chemically unreactive and environmentally friendly. Their advantages include their resistance against marine borers and recycling properties. The Port of Los Angeles has applied the new technology to several projects and has expressed satisfaction with the material's performance. The purchase prices are higher but these are offset by the piles' durability and the elimination of disposal costs.

Plastic pipe takes sewer under creek

Article Abstract:

Engineers made use of a polyethylene pipeline to prevent sewage from contaminating a natural creek which intersects the sewer lines. The Chevron Chemical Co.'s Plexco/Spiralite pipe's length, light weight and immunity to corrosive gases made it a viable choice for the Big Creek Interceptor Project in Englewood, Colorado and replaced the city's original sewer line. A system of four pipes diverted the sewage below the creek and siphoned it to its original level on the opposite side. These pipes are concrete-coated to prevent seepage of sewage into the ground and the stream.
