Product Description


Rock Wool Pipe Insulation for Industrial Boilder is made from natural rock such as basalt, diabase and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500°C. And the melts lavais then pour to high speed spinners through which the melts get into fibers. The just fiberized fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as board, mat and pipe section etc with different usage.


  1. Non-combustible material.
  2. Acoustic noise reduction.
  3. Waterproof and anti-moisture.
  4. Easy to install.
  5. Good safety.
  6. Good weathering performance.
