手机捕鱼万能辅助器PIR serve to cold insulation of pipelines and equipment in temperature range from -196℃ to 120℃, provides efficient and stable cryogenic thermal insulation effects as transmission media such as Liquefied Nitrogen (LN2, -196℃), Liquefied Natural Gas（LNG, -162℃), Liquefied Ethylene Gas(LEG, -104℃), Liquefied Petroleum Gas(LPG, -48℃) etc, commonly used in oil refinery, chemical, ethylene and fertilizer industries, as well as refrigeration house and LNG systems.
Packing and Storage
手机捕鱼万能辅助器Outer packing with carton, special requirment is available according to request;
Store in a dry, shady, and ventilated place, keep away from heat source and protect from exposuring under sunshine.
Application and Cautions
手机捕鱼万能辅助器PIR shall be handled gently, avoid rolling, shall not place heavy good on top, collision and heavy pressure during moving and transporting.
When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band. During construction, if needs it can be cut to shape by saw.
