BROAD rock wool 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.

Scope of 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.
