Description:
rock wool shell of pipe is made of natural basalt as the major materials which are made into man-made inorganic fibers by fast centrifugal equipment after high-temperature melted, and at the same time adding special adhesives and dust laying oil. It can be made into various rock wool heat-preserving shell of pipe with different specs and requirements by heating and solidify. Also, rock wool can be composite with glass wool and alumina silicate wool into heat-preserving shell of pipe.
Application:
Heat insulation of various hot and cold pipelines, and hidden and exposed pipelines.
Heat insulation of pipelines in electric power, petroleum, chemical industry, light industry, metallurgy and etc.
Distinctive advantages:
Sound absorption and noise reduction; it can effectively prevent syntony.
Light materials; easy for installation.
Antisepsis, ageing resistance and anticorrosion, ensuring a healthy environment.
Low moisture absorption; stable physical properties.
Low thermal conductivity; high heat preservation.
Grade A1 fireproof; incombustible permanently.
Strong resistance to extrusion and impact.
Recommended pipe wall thickness of thermal insulation materials:
