FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. At least one pipe (4) is placed in mould of shape reproducing that of said part (1) and poured with light alloy. One part of pipe (4) is subjected, prior to placing it into mould, to surface processing to create heat barrier between said pipe part and poured metal. Said mould comprises at least one locating chamber around pipe (4) to make pipe holder (5) extending from moulded part (1) wall (2, 3).
EFFECT: optimised weight of jacket at moulding of inner pipes.
