To avoid any damages to clay pipes and fittings at the stage of loading, unloading, transporting, storage and lowering into a trench, a special handling method should be adhered to.
Pipes are packed in bundles or pallets by using a wooden base and spacers to make up separated layers of pipes, held together by steel bands, ensuring that socket spigot ends do not touch each other or the ground surface.
Type of packaging of fittings depends on its weight and shape. They are usually delivered in wooden box containers or arranged into pallets or bundles.
On delivery at site, the pipes and fittings should be checked for any damage incurred during transport simply by wiping them out at the socket and spigot ends with a suitable white powder (e.g. talcum powder). Even the finest cracks become visible when this quick method of testing, which can easily be carried out on site is used.
Loading and Unloading
Pallets are loaded/unloaded only by convenient equipments (i.e. a forklift) which does not allow any damages to pipes and fittings.
Dropping , lifting or lowering pipes with jerking movements or suddenly letting them to the ground will cause damages. In case of other lifting machines (i.e. cranes) is used for loading and unloading, wooden bars must be laid between the slings to ensure that no damages occur to the pipes.
Storage and Transportation at the site
Any site machinery can be used for offloading which does not permit damage to pipes and fittings. (A forklift is the most efficient).
Dragging or rolling pipes is not allowed. Packs or individual pipes should be set down on a reasonable leveled surface and off the ground by a square timber to protect the "K" joint of spigot end from any damage.
Lowering into the Trench
The pipes should be lowered in the trench in a proper manner (i.e. with ropes or protected straps) by means of suitable lifting tackle.
