Proposed ASTM Standard Supports Water Main Pipe Rehabilitation
ASTM International’s committee on plastic piping systems (F17) is developing a proposed standard for replacing old and failing distribution water main pipes.
The new standard (WK69438) will describe technology that takes a new, deformed U- or C-shaped HDPE pipe, inserts it into a failing water main and expands it with steam and air pressure back to its round shape, creating a new structural pipe-within-a-pipe. This allows for hundreds of feet to be installed in an application, creating a jointless and leak-free pipeline.
Engineers, cities, water utilities, and inspection organizations will be the main users of the proposed standard.
ASTM International positively impacts public health and safety, consumer confidence and overall quality of life by integrating consensus standards and innovative services to improve lives.
