FIELD: gas industry, possibly compressor stations for increasing pressure of natural gas at transporting it. ^ SUBSTANCE: compressor station includes gas pumping aggregates, mainly with full-pressure forcing pumps. Said aggregates are connected in parallel through technological pipelines of collector manifold by their inlets to system for preparing at least technological gas and by their outlets to plant for cooling technological gas. Through shut off fittings, supply and discharge pipelines said aggregates are connected to main gas conduit. Plant for cooling technological gas is provided at least with one apparatus for air cooling of gas. Said apparatus includes at least two heat exchange sections, each section having gas pressure vessel in the form of multi-row bundle of ribbed tubes. In one row tubes of said bundle are shifted relative to tubes of adjacent rows of the same bundle. Rows of tubes are mutually divided through spacing members in the form of folded plates having alternating along their length concave and convex portions forming supporting surfaces for tubes of adjacent (along height of bundle) rows. Spacing member has such configuration that extreme cross lines of upper concave portions are shifted along height relative to arbitrary plane passing through respective extreme cross lines of lower concave portions of folded member. Said extreme cross lines may be over said plane by gamma1-part of thickness of spacing member and under said plane by value gamma2 <= 0.11d. Pitch n of wrinkles of folded member along length of spacing member n = (1.01 -1.75)d where d - outer diameter of tube ribs. Improved design of folded spacing members provides optimal operation modes of heat exchange section due to more close arrangement of ribbed tubes in bundle. ^ EFFECT: enhanced efficiency of compressor station, lowered labor and material consumption, improved factors of heat exchange and operational reliability due to optimized parameters of heat exchange ribbed tube bundle used in compressor station of apparatus for air cooling of gas. ^ 24 cl, 4 dwg |
