American Concrete Pipe Association Aids in Municipal and Roadway Pipe Inspection

http://www.concrete-pipe.org

As post installation inspection of underground storm systems becomes
accepted practice in municipalities across the nation, the American Concrete
Pipe Association has stepped up its efforts to provide hands-on experience and
tools to contractors, consulting engineers and Department of Transportation
personnel.

Dozens of post installation inspection demonstrations have been hosted by
members of the ACPA, attracting hundreds of participants in several states.
These demos typically include three key components, each led by industry
experts:

Detailed overview of post installation inspection and reinforced concrete pipe
evaluation procedures; Introduction to, and overview of, robotic video and laser
profiling analysis; and Plant tours

Presentation topics typically include proper gasket and joint installation,
identifying and repairing minor pipe damage, and each state DOT’s pipe
inspection expectations.

During most tours of concrete pipe plants, viewing stations are set up to allow
participants to observe reinforcement cage production, cage delivery, pipe
removal from the floor, rounding ring removal, the pipe production machine,
pipe production cycle, removal of the pipe to kiln cars, tip out, deburring,
stenciling, quality control, yarding, a three-edge bearing (3EB) test, and
autogenous healing.

At a recent plant tour in Maryland, four units of pipe were intentionally cracked
(to 0.01 and ultimate) a month earlier at the autogenous healing display. The
pipes were displayed bell down on mastic sealant and filled with water. By the
time of the demonstration, the units were almost completely healed.

"The vast majority of storm system owners now understand that the only way to
adequately ensure the service life of a pipe system is to confirm that it has been
both designed and installed correctly," said Matt Childs, president of the ACPA.
"Post installation inspections are an integral part of that process to verify that
the pipe system incurred no damage during the construction phase that may
result in excessive maintenance or unanticipated failures down the road."

The ACPA has urged storm system owners to conduct post installation
inspections on all types of pipe systems as a commonsense approach to quality
assurance.

The Association has developed a PII Demonstration Tool Kit for its members
that includes sample PowerPoint presentations, how-to notes for key
demonstration components, and plant tour suggestions.

About the ACPA
The American Concrete Pipe Association (ACPA) is a nonprofit organization
composed primarily of manufacturers of concrete pipe and related conveyance
products located throughout the United States, Canada and in more than 40
foreign countries. ACPA membership also includes manufacturers of equipment
and/or providers of products and services related to the concrete pipe industry.
Established in 1907, ACPA (www.concrete-pipe.org) provides members with
research, technical and marketing support to promote and advance the use of
concrete pipe for drainage and pollution control applications.
