Receiving, Handling and Storage of PVC Pipe


Receiving Pipe

As pipe is received, it must always be thoroughly inspected, prior to unloading. The person receiving the pipe must look for any transportation damage cause by over-tightened tie-down straps, improper treatment, or a shift in the load. Pipe received in a closed trailer must be inspected as the trailer is opened. Take extra time to ensure that the pipe has not been damaged by other materials having been stacked on top of it, load shift, or rough handling. Visually examine the pipe ends for any cracks, splits, gouges, or other forms of damage. Additionally, the pipe should be inspected for severe deformation which could later cause joining problems. The entire inside diameter of lager diameter pipe (4” and above) must be checked for any internal splits or cracks which could have been caused by loading or transit. The use of a flashlight may be necessary to perform this inspection. Any damages must be observed by all parties involved, including the driver, and should be clearly noted on the bill of lading and/or delivery ticket. A copy of this document should be retained by the receiver. In addition, the manufacturer and carrier should be notified, within 24 hours of any damages, shortages, or miss-shipped products.

Handling Pipe

The pipe should be handled with reasonable care. Because thermoplastic pipe is much lighter in weight than metal pipe, there is sometimes a tendency to throw it around. This should be avoided. The pipe should never be dragged or pushed from a truck bed. Removing and handling pallets of pipe should be done with a forklift. Loose pipe lengths require special handling to avoid damage. Precautions to follow when unloading and handling loose pieces include not banging lengths together or dropping lengths, even from low heights, on hard or uneven surface. In all cause, severe contact with any sharp objects (rocks, angle iron, forks on forklifts, etc.) should be avoided. Also the pipe should never be lifted or moved by inserting the forks of a forklift in to the pipe ends. Handling PVC pipe particularly diameter greater than 4-inch requires extra care as the added pipe weight can cause cracking from relatively minor impacts. Also plastic cause cracking from relatively minor impacts. Also plastic pipe becomes more brittle as the temperature decrease. The impact strength and flexibility of PVC and pipe are reduced. Therefore take extra care when handling skids or loose lengths when the temperature drops below 50°F.

Storing Pipe

If possible, pipe should be stored inside. When this is not possible, the pipe should be stored on level ground which is dry and free from sharp objects. If different schedules of pipe are stacked together, the pipe with the thickest walls should be on the bottom. If the pipe is pallets, the pallets should be sacked with the pallet boards touching, rather than pallet boards being placed on the pipe. This will prevent damage to or bowing of the pipe. If the pipe is stored in racks it should be continuously supported along its length. If this is not possible, the spacing of the supports should not exceed their feet (3”) The pipe should be protected from the sun and be in an area with proper ventilation. This will lessen the effects of ultraviolet rays and help prevent heat buildup.
