Heat preservation of piping
The cylindrical heat preservation pipe materials produced with glass wool by formation through curing by applying pressure and heating after applying thermosetting cement are widely used for thermal insulation and heat preservation of thermal piping, cold water and hot water piping and steam piping in electric power, petroleum, chemical industries. They feature easy execution of works, remarkable energy-saving property. Veneering like aluminum foil can be applied to the surface as decoration and means of preventing moisture and radiation protection.
