Storage And Transport
UPVC pipes are strong but light, with a specific gravity of approximately one-fifth that of iron. As a result, these pipes are easier to machine than their metal counterparts. However, reasonable care should always be used. Since the strength of any joint depends on the condition of the bell and ring, special care must be taken in handling, handling and storage to avoid damaging the ends.
When loading pipes into vehicles, pipes should not be damaged by break bars, loose nail heads, etc. Care should be taken so that they do not come into contact with sharp corners such as
During transport, the pipes will be well fixed along their entire length and should not be allowed to be projected unsafely on the rear panel of the truck.
Pipes should be lowered during unloading, not dropped to the ground. Pipes can be removed from trucks by gently rolling them down into the woods, taking care that the pipes do not fall on top of each other and on any hard or uneven surface.
Adequate support should always be provided to the pipes. Pipes should not be stacked in large piles, especially in warm temperature conditions, as the substrates can deform, causing difficulties in joining and pipe alignment. Any pipe with ends prepared for jointing (muff and ring joints, etc.) should be stacked in layers with sockets inserted into the other ends of the stack and sockets. The prepared pipe ends (the belled side) are positioned more protruding than the stacks, so they are not deformed by the weight on them.
For long-term storage, pipe racks must provide continuous support. For dimensions below 160 mm, closer supports will be required. In this type of pipe rack, pipes cannot be stored more than seven floors or more than 6ft (1.8m) high. Whichever is less, but if different diameters are kept in the same racks, then the largest diameter bores and the thickest pressure classes should always be placed at the bottom. For temporary storage in the area where shelves are not provided, the floor should be flat and free of loose stones. Pipes stored in this way should not exceed three levels and should be stacked to prevent movement.
