Storage

When handling the finished products, it is necessary to use the designated means of tethering and to handle the products in such a way as to avoid the damage or deformation of the casing, the ends of tubes prepared for welding, the alarm system wire, the protective elements, or the markings. Parts of the Hart-pipe system can be transported by a suitable truck with a cover sheet.

Loading and unloading should only take place under the professional supervision of the pipe supplier or after the operator has familiarized themselves with the Hart-pipe product handling principles. Pipes must not be thrown, dragged on the ground, or rolled, as this could damage the casing pipe. When loading and unloading pipes, only hooks wrapped with rubber hose may be used to prevent damage to the edges treated after welding. Only textile tapes with a minimum width of 100 mm may be used to wrap the pipes. Steel cables shall not be used to handle pre-insulated pipes or other elements of the pre-insulated system. Product durability depends greatly on proper storage and care.

Hart-pipe components are stored in enclosed storage or under shelter to ensure that the insulation is dry during installation. They shall be stored on a flat base without permanent one-sided loading and deflections and shall not rest on sharp edges. The storage site must be secured with a side barrier to prevent the pipes from rolling. With an uneven pad, it is necessary to adjust the storage site to form a plane using pads 150-200 mm wide, axially spaced at a maximum distance of 2 m. The storage height must not exceed 2 m. The ends of the pipes are unwrapped on site before being welded together to avoid possible damage to the welding edges.

It is only permitted to store pipes and other components in the open while preparing for their installation, but for no longer than 3 months. They must not be mechanically damaged and extreme weather conditions, such as prolonged sunlight in the summer and frost below -10 °C in the winter, must be avoided. Joint accessories that are packed in their own box must be stored indoors until the assembly. Increased care must be taken when handling the material at temperatures below 0 °C, as the material becomes fragile.
Violating the principles of assembly and handling listed above or keeping the products in storage beyond 3 months from delivery will result in the supplier's warranties becoming void.

Pipes and fittings must be stored on a level, paved surface. The pipes must be secured against shifting. The pipes are stacked in a so-called pyramid shape without interlacing, so that they lie on top of each other along their entire length. However, the maximum height is 2 m. Accessories, i.e. joints (including assembly instructions), sealing rings, shrink sleeves, etc. are stored in a box and are protected against mechanical damage.
