HEAT INSULATION OF AIR ELIMINATOR FOR OVERHEAD AND UNDERGROUND ERECTION Russian patent published in 2014 - IPC F16L59/00 F16L59/16 

FIELD: process engineering.

SUBSTANCE: invention relates to heat insulation of oil mains and process lines. Proposed method comprises measurement of geometrical sizes of air eliminator. Note here that case composed of two or more parts of thin-sheet zinc-plated steel is made in shop to mate the definite air eliminator. Foam glass covering layer is fitted on said case with the help of mastic. Covering seams at case part are bonded by sealing materials. Anti-abradant for air eliminator covering is applied on foam glass surface in contact with air eliminator. Locks, metal ties with locks and tapping screws are used for bonding of covering with case parts.

EFFECT: invention ensures conservation of the product temperature that is pumped through the air vent, the ability of vent access, including maintenance and repair.
