Transportation and storage of PEX pipes and tubing

Keeping pipes from polymeric materials

It is recommended for possible extended period of time to keep the pipe in packaging manufacturer.

Tubes can be stored in warehouses or outdoors. In the latter case, the pipe is desirable to protect from direct sunlight. Necessary to ensure the safety of pipes and fittings from physical damage, deformation and contact with them, oil and fats.

Pipes should be stored in piles no higher than 2 meters on flat ground. When storing the pipes in the packaging of the manufacturer, they can be installed at each other with an emphasis on the wooden frame, but not more than 4 layers.

Not bonded pipe should be stored on firm ground as shown in Figure 1.

Transporting, packing, loading and unloading pipes from polymeric materials
Works related to the transportation, loading and unloading of pipes, fittings and piping components of high-density polyethylene (PE), should be carried out at a temperature not lower than minus 20 ° C. It is necessary to take measures to avoid the possibility of mechanical damage and harmful strains, leading to their destruction, especially at low temperatures.

When transporting the pipe shall be laid on wooden slats, securely fastened to the bottom of the truck. Wooden slats also placed between the layers of tubes (see Fig. 3).

To fix the most extreme of pipes used wedges to prevent movement during transportation.

To prevent the movement of internal tubes during transport and damage between them is recommended to lay rubber gaskets.

In order to keep all the pipes together, the entire series should be protected with plastic wrap ribbons. In addition, the sides of the truck must be vertical racks to ensure immobility and safety of pipes for transportation on uneven and inclined sections of the road.

To reduce the cost of transporting the pipe can be packed in telescopic (nested one inside the other). In this case, you must follow special instructions for loading, processing, storage and transportation with the use of fork lifts. Loading / unloading of pipes produced by one, beginning with the pipe of the biggest / smallest diameter. Manipulations are made with care, avoiding pipe graze each other, see Figure 4.

When handling such packages should have the following general procedure:

1. It is always necessary to remove (lift) sub-bundle, using at least two lines (Fig. 5). Straps should be used of sufficient strength, because of the large weight of the package. The strength of a sling can be calculated by weight characteristics of pipes (see Specification).

2. The nested tubes are usually best stored in the transport packaging. Accumulation of these packages on-site storage (storage) is not desirable. Do not stack bags like pipes in the stack, if it is not stated specifically.
3. Packages nested one inside the other pipes can be safely transported only in the original shipping packaging. Special requirements, if any, from the points of support, accommodation and / or secure during transport should be defined for each project.
4. Removal of packing and removal of tubes from the package is best done on a specially prepared site. As a rule, the court should be set three or four fixed support, calculated on the external diameter of the largest pipe of the package. Removing packages from each inner tubes produce slightly lifted her on a special inserts a rod, so that it does not concern the other pipes. If the weight, the length of pipe and / or other hardware limitations prevent the use of this method, the procedure extracting inner tube from the package must be determined separately for each project.
