COLUMBUS, OHIO - Pipe extruder Advanced Drainage Systems Inc. has announced its hometown city of Columbus has approved corrugated polyethylene pipe for sewer and drainage uses. The city approved ADS N-12 pipe, with diameters from 8 inches to 48 inches, for use under pavement, the company said.
Since 1993, ADS said, 135,000 feet of pipe was installed and tested at 30 residential subdivisions in the city, under a provisional approval. City engineers used video cameras to inspect a 10,000-foot stretch of the pipe, said Tom King, ADS vice president of engineering.
ADS officials also said they expect the number of U.S. installations for its smooth-wall N-12 HC pipe should be double the number in 1995. The smooth-wall pipe was introduced in 1994, and was targeted to the storm-sewer market; but the firm is exploring other applications, said Tony Radoszewski, director of marketing and business development.
James Goddard, ADS chief engineer, said the pipe has a high strength-to-weight ratio. Circular ribs create a honeycomb cross section, which increases ring stiffness, Goddard said. N-12 HC pipe has been installed in 30 states, the company said.

ASTM revises specs for folded PVC pipe
WEST CONSHOHOCKEN, PA. - ASTM's Committee F-17 on Plastic Pipe Systems has revised its F-1504 standard specification for folded PVC pipe for rehabilitation of sewer and conduit pipes.
The revision, the result of two years of research and development, recognizes an additional cell classification for the folded PVC pipe.
The no-dig technology inserts a folded PVC pipe into the old pipe, then expands it to conform to the wall of the original, forming a pipe within a pipe.
ASTM is based in West Conshohocken.
Gentek sides with random-grain look
CLEVELAND - Gentek Building Products Inc. has created a vinyl siding that duplicates the random-grain pattern of wood siding.
The siding, Northern Forest, comes in seven shades. Each shade has intertwining natural colors that create the woodgrain appearance. The siding is Gentek's top-of-the-line product.
To make Northern Forest, Gentek engineers improved the Timberwood line, boosting the contrast between color tones on the siding, according to an official of the Cleveland company. He declined to reveal how the company adds the grain pattern.
