FIELD: pipeline engineering.
SUBSTANCE: method comprises setting the pipe with centering members inside the shell to define a ring space, sealing the ring space by means of plugs, and setting a heat insulating material in the space. The rolls of mineral cotton is set in the shell through the spinneret whose diameter is equal or less than the inner diameter of the shell.
EFFECT: enhanced reliability.
