The invention relates to the field of transportation and storage, respectively, in pipelines and tanks freezing liquids at low ambient temperatures, for example, in the winter.

Famous people's way of preventing tanks from rupture during freezing water in them by dipping them wood (logs, planks, etc.) by binding to them heavy objects (bricks, metal object, and so on). Thus, the water expanding when freezing presses on the wood, keeping the vessel wall intact.

The disadvantage of this method is that the immersion of the wood is not feasible, for example, in pipelines, water supply, heating and Sewerage systems, boilers, titans, heat accumulators, etc.

The purpose of the present invention to ensure the safety of vessels (pipelines, tanks, etc) during transportation and storage in any expanding when freezing liquids.

This goal is achieved by immersion in existing vessels (tanks and piping) compensators (fragments, balls, etc. from not absorb water plastic materials, shrinking under pressure when its freezing, and designed for these purposes, new tanks and pipes in the future are covered from the inside, this calculated thickness of the plastic materials that will allow them to get rid settle them on the walls of precipitation, sludge and scum due to temperature fluctuations.

To achieve this goal in tanks of cold water plunge compensators or balloons not absorb water from plastic materials, shrinking under pressure when its freezing. In the pipes for cold potable water and sanitation are the joints or garlands of balloons, tied together with a cord and made from non-absorbent plastics material, compressible under pressure when its freezing, and the ends of the cord near the valves are fixed to a welded welded inside the tube clamps. In tanks for hot water and heating pipes have expansion joints, made from non-absorbent plastics material, compressible under pressure when its freezing, the ends of which the valves are fixed by clamps, welded welded inside the pipe. New tanks and pipes manufactured to store them and transport them freezing at low temperatures of liquids in industrial conditions inside covered not absorb these fluids plastic materials, shrinking under pressure when its freezing.

The present invention is illustrated by figure 1, 2, 3 and 4.

According to figure 1 in the tank 1 water 2 recessed air ball (ball) 3 basket 4, which is the load 5 (CI is the pich) to prevent the ascent of the ball, because without this it will not perform the functions assigned to it to protect the tank from bursting in freezing water.

According to figure 2 in the existing pipe 1 for cold water 2 is a garland of balloons 3 from non-absorbent plastics material, compressible under pressure when its freezing, which are interconnected by a cord 4, the ends of which the valves (not depicted in figure 2) is fixed to the welded inside their buckles 5.

According to figure 3 in the pipe for hot water 2 over its entire length is calculated with a certain volume compensator of not absorbing water plastic material, compressible under pressure when its freezing, and figure 4 shows the pipe 1 from the inside along the entire length in production conditions covered not absorb water 2 plastic material 3, a compressible under pressure when its freezing, with calculated thickness.

1. The way to prevent failure of the vessels in freezing water containing tank or piping from freezing at low temperatures water with submerged joints with settlement by a certain amount of shrinking from pressure during freezing in the water vessel materials, characterized in that the vessels sink compensators of not absorb water and shrink the category from its pressure plastic materials.

2. The method according to claim 1, characterized in that in the existing tanks for cold water sink compensators in the form of balloons with baskets for placement potoplyayuschy cargo.

3. The method according to claim 1, characterized in that in the existing extended cooling water pipes and sewer expansion joints are made in the form of garlands interconnected by means of a cord balloons at the ends of the cord from the side of the valve is fixed in the clamp welded welded inside the pipe.

4. The method according to claim 1, characterized in that in the existing tanks and piping for hot water placed expansion joints, the ends of which side of the valve is fixed in the clamp welded welded inside the pipe.
