Materials Section - City of Xenia

2.2 Materials - All C-900 PVC pipe shall be made from Class 12454-A or Class 12454-B virgin
compounds as defined in ASTM D-1784, with an established hydrostatic-design-basis rating of
4,000 PSI for water at 73.4 F.
2.3 Pipe and Gasket - C-900 PVC pipe shall have a cast iron outside diameter and shall be
suitable for use as a pressure conduit. All pipe shall be Pressure Class 150 DR18 unless
otherwise specified on the plans and approved by the City Engineer. Provisions must be made
for expansion and contraction at each joint with an elastomeric sealing ring. Laying length shall
be 20-feet ±. The joint shall be in compliance with the requirements of ASTM D-3139.
2.4 Marking - C-900 PVC pipe shall be marked as prescribed by AWWA standards; i.e.,
nominal pipe size, dimension ratio (DR), AWWA pressure class, manufacturer’s name and code,
and seal of testing agency that certified the suitability of the pipe material for potable water
service.
2.5 Approvals - All C-900 PVC pipe used in Xenia must be listed by Underwriters Laboratories
and comply with all applicable AWWA requirements.
2.6 Exposure to Sunlight - PVC pipe shall be covered to prevent prolonged exposure to sunlight
(ultraviolet rays).
2.7 Extreme Cold - No installation of PVC pipe shall be permitted when air temperature is
below 10 degrees Fahrenheit.
2.8 Receiving, Handling, and Storing Pipe Shipment - All shipments should be inspected as
soon as possible after arrival. After examining the load for any damage that may have occurred
during transit and checking the quantity, size, and class of pipe against the packing slip, the
unloading of the pipe can begin.
The preferred method of unloading is to remove each unit intact by the use of mechanical
equipment. The units should be picked up with a forklift truck or by a sling, being careful to
avoid excessive swinging. Since the impact strength of PVC pipe decreases in cold weather, care
should be taken neither to drop the pipe nor to set the pipe down on sharp, protruding objects. If
the pipe is to be stacked in racks, support it every 4-feet. Do not throw, whip, or drop the pipe
and do not use chains to unload. The pipe should be stored away from mud and water with every
attempt to keep it clean.
3.0 Ductile Iron Pipe Water Main
3.1 Ductile Iron - Ductile iron pipe shall conform to the American National Standards Institute
Specification for “Ductile Iron Pipe Centrifugally Cast in Metal Molds for Water or Other
Liquids,” ANSI A21.51 (AWWA C151).
