Pipeline Insulation Rock Wool Pipes
Yu Ou Nuo rock wool pipe is a kind of rock wool insulation material which is mainly used in pipeline. It is made of natural basalt as the main raw material. After high temperature melting, it is made into artificial inorganic fiber by high-speed centrifugal equipment. At the same time, it is added with special binder and dust-proof oil, and then heated and solidified to make rock wool insulation pipes of various specifications and requirements. Rock wool pipe shell is a kind of resin rock wool insulation pipe shell and waterproof rock wool insulation pipe shell, which are made of selected diabase and basalt slag as the main raw materials, melted at high temperature and sprayed with special adhesive and waterproof agent in the process of high-speed centrifugation.
