Crumpler Plastic Pipe, Inc. makes every effort to ensure order accuracy
and quality. As a final check, the customer should conduct a personal
inspection at delivery to verify that the correct product and the expected
quantity is received. Pipe corrugations, gaskets, pipe ends, couplers
or other joints, and any accessories should be visually inspected for
damage that may have occurred during shipment.
Product markings on Crumpler Plastic Pipe will
include the following information to facilitate job-site inspection.
- Nominal pipe size
- Manufacture’s name
- Date code
- Applicable standard(s)
The Contractor should set aside an area for products to be stored
onsite. This area should be flat, free of large rocks, rough surfaces
and debris. It should also be out of the way of construction traffic.
Pipe may be delivered either palletized or loose, depending on the
type and quantity of product. Pallets maybe unloaded with a backhoe,
forklift or other piece of equipment and nylon sling or cushioned cable.
The sling should be wrapped around the pallet at the third points as
it lifts the pallet onto the ground. As an alternative to using a sling
to unload full pallets, the pallet maybe opened and lengths of pipe
unloaded individually by carefully rolling single lengths of loose
pipe from the delivery truck onto the front-end loader, then onto the
ground. Alternately, the pipe can also be lifted using a nylon sling
or cushioned cable at the third points.
Weight of Individual
Joints of Pipe
||End handling with
a forklift should
not be used, as
pipe damage will
occur. Due to
joint weight, larger
should not be off
loaded by hand.
Job Site Storage
Reasonable care should be used in handling
pipe. The pipe should not be dropped, dragged or bumped against other
pipe or objects. Palletized pipe should remain in the pallet for jobsite
storage. Non-palletized pipe can be stockpiled for temporary storage
in a flat debris free area out of the way of construction traffic.
Begin the stockpile with secured timbers spaced the width of the proposed
stockpile at a distance not exceeding the third points. For pipe with
attached bells, a recommended stacking method is to alternate the direction
of the pipe lengths so that the bells are not stacked on each other.
As shown in Figure 2, up to three pipes can be laid before alternating
directions. Subsequent layers should follow that same pattern as the
first but with fewer sticks of pipe in each row. For smooth interior
pipe, storage space can be minimized by nesting smaller diameter pipe.
Factory installed gaskets on the spigot should be protected by positioning
them between corrugations.
Stringing the Pipe
| Placing the pipe and accessories along the open trench, or “stringing,” can
save handling time. Each pipe length should be laid on a level
surface as near as possible to the trench on the side opposite
the excavated trench material; allow some space between pipe to
protect pipe ends. The pipe should be out of the way of any equipment
in a location that will allow excavation to proceed uninterrupted.
