Acceptable storage of plastic pipes

The pipe storage surface must be level and free of stones. Pipes must be layered and stacked in a way that avoids the risk of damage or permanent deformation.

Larger-diameter, thin-walled pipes must be fitted with stiffening rings. Avoid single-point or narrow longitudinal supports.

The list below gives recommended maximum stacking heights for non-palette pipe storage. Provided pipes are stacked on palettes and protected against sideways movement, the nominal stacking heights specified in the list may be increased by 50%.

Pipe storage areas should be as well-protected as possible.

Absorption of oil, solvents and other chemicals must be avoided at all costs during storage. Stored pipes must not be exposed to the elements more than absolutely necessary, i.e. they should be kept in a covered warehouse. If stored outdoors (e.g. on a construction site), they should be covered with sheeting for protection against the weather (e.g. UV radiation).

It should also be noted that one-sided warming by sunshine could cause deformations.

Pipes and parts should be used in the order of manufacture/ delivery, to ensure proper warehouse turnover of the plastic material.
