PREMANT district heating pipe

PRE 6.403

Storage of preformed parts

Caps at the ends of formed parts protect the medium pipe against external influences. These protective caps should not be removed until the pipe

is

fitted on site.

Approved formed parts should be stored

flat and dry.

Formed parts can also be stored on flat pallets and in mesh boxes in a pyramid formation. The parts should be stacked on top of one another in a

manner that ensures stability and an even distribution of weight. Where necessary, stacks on flat pallets should be secured with wedges.

Most importantly, the ends of formed parts should not face upwards. It is imperative to prevent the accumulation of water on the insulation layer

(between the medium pipe and casing pipe) to protect the pipe ends against corrosion.

In general, formed parts should be protected from frost and direct sunlight.

They should also be protected from improper handling such as the effects of impact, shock, bending, etc.
