What are the application areas of rock wool roll felt and rock wool pipe shell insulation materials for cement plants? Rock wool roll felt and rock wool pipe shell are the two most widely used types of rock wool products in insulation engineering of cement plants. Although both belong to the rock wool material, their application scenarios in cement plants have different divisions due to their different forms and performance focuses. Rock wool roll felt is mainly used for insulation of large-area, irregular or non-standard pipeline equipment due to its softness, continuous rolling, and easy cutting characteristics. Rock wool pipe shell is a hard/semi-rigid product pre formed into a semi-circular or circular arc shape, designed specifically for circular pipelines. It is easy to install, has fewer joints, and has a more uniform insulation effect.
