METHOD OF PRODUCING AND MOUNTING BUILT-UP HEAT-INSULATION PIPE COAT AND PIPE WITH AFORESAID COAT

摘要

FIELD: machine building.;SUBSTANCE: invention relates to pipeline construction and mounting. Proposed method comprises adding reinforcements and other fillers to binding materials. Note that one part of a binder represents low-melting material spherical balls, while the other one is made up of spherical hollow thin-wall glass-ceramic granules with a high coefficient of heat wave refraction. Note also that quick-hardening solution makes a binder. Mind that, coat parts hardened, they are subjected to roasting at low-melting filler granule materialy temperature till a complete burning out. Built-up heat-insulation pipe coat has its binder one part representing low-melting material spherical balls, while the other one is made up of spherical hollow thin-wall glass-ceramic granules with a high coefficient of heat wave refraction.;EFFECT: higher heat insulating and strength properties.;16 cl, 4 dwg
