Product Details

Rock wool pipe is a kind of rock wool insulation material mainly used in pipelines. Rock wool pipe shell is widely used in the insulation of boilers and equipment pipes in petroleum, chemical plants, metallurgical industry, ships, textile industry, etc. It is also used for the insulation of partition walls, ceilings and interior walls in the construction industry, as well as the insulation of various types of cold and hot pipes and hidden and exposed pipes.

Product Introduction

Rock Wool pipe is particularly suitable for energy conservation in hot and cold pipelines andplay an important role in maintaining constant temperature, protecting personal safety,preventing condensation and reducing noise. This product is rolled with a mold, closelymatched with the pipe, and the outer surace is polished to achieve precise insulation thickness.

Product Handling

Rock Wool pipes are lightweight and easy to handle. To cut the product, it only requires asharp knife with serrated edge or a hand saw, measuring tape and steel ruler. Rock Wool pipes should be secured in position using wire or metal bands in accordance with themanufacturer's recommendations and protected by metal cladding, mastic or othersuitable coatinas if required.
