Building materials rock wool pipe insulation material rock wool pipe

Rock wool pipe takes basalt as the main raw material. The basalt is made into a kind of inorganic fiber by high-speed centrifugal equipment after melting in high temperature. At the mean time, adding a certain percentage of binder, dust laying oil and silicon oil. Heat insulation is the biggest performance.


Rock wool pipe Widely used in the thermal insulation of the industrial boiler and equipment pipe in the fields of ptroleum,chemistry,metallurgy,ship building,and textile as well as the thermal insulation and sound absorption of partition,ceiling and internal and external wall in building area.
