Passing quality control at each stage of production Caloree PP-R pipes and fittings are packed after final control, visual inspection. While PP-R pipes are put into nylon bags, PP-r fittings are packed with cardboards. Later the products are stowed on wooden pallets that fit the product sizes. Pipes and fittings on pallets are wrapped by PVC strap to prevent possible damage due to wobble and friction. Tension belts and airbags used to support the pallets in the vehicle minimize the possibility of damage during transportation.
