FIELD: refining of oil and petroleum products. SUBSTANCE: plant has support (2′) on which fixed sections of pipe line are immovably secured; each section is connected with articulated pipe line (3′) which is deformable in certain horizontal plane. Other fixed sections ((B′1) are located at one level along reference line (L′) oriented strictly in level. String (8′) terminating at level of reference line is engageable with end of each articulated pipe line. Each string is adaptable for motion along reference line for transversal deflection in definite range from this line to ensure opposite divergence of these strings near this line. EFFECT: possibility of automatic functioning of plant. 34 cl, 7 dwg
