FIELD: circulation of petroleum products. SUBSTANCE: frame is made in the form of a parallelogram, secured on whose two adjacent sides are the end sections of the first and second successive rows of pipe runs furnished with blind sections. The translation control unit is fixed on the two other adjacent sides. The pipe run is made in the form of a line interconnected by means of sealed coupling joints with position of release of identical modular sections, whose number in each successive row of pipe runs is lower by one as compared with the number of pipe runs in the other successive row. Each modular section of one pipe run faces the pipe run of the other successive row. Each line is connected to the circular section at one end, and to the blind section fixed to the translation control unit- at the other end. The length of the modular section of pipe runs of each successive row equals the distance between the pipe runs of the other successive rows. Installed in parallel with each pipe run are guide rails that carry modular sections and blind section of each pipe run for slip with formation of a gap in it between any sections. The coupling member is made up of a central and two transverse sections, shifted in the length of the central section over a distance equal to the distance between two successive rows of pipe runs with formation of two pipe straight elbows inside the coupling member. EFFECT: enhanced reliability. 6 cl, 6 dwg
