Industrial Rock Wool Pipe

As the flagship product in the field of pipeline insulation, rock wool industrial insulation pipe is made of natural basalt as the main raw material. It is melted at a high temperature of more than 1450℃ and spun into soft rock wool fiber using the internationally advanced four-wheel centrifugal method. Then, an appropriate amount of binder and waterproofing agent are added, and it is made through precision processes such as curing and cutting. Its cylindrical design fits the pipe perfectly, making it an ideal choice for various industrial pipe insulation.

Product Introduction

1. Product Description

SUNTHERM industrial thermal insulation rock wool pipe (SUN series) is made of rock wool fiber rolled with a mold and cured at high temperature. For easy installation, it is single-sided along the axis of the pipe shell, which is convenient for construction and can ensure that the pipe shell and the pipe that needs insulation fit closely. The outer surface of the pipe shell can be polished according to customer requirements to ensure the precise consistency of insulation thickness. Low-chlorine products can be produced according to requirements. According to different application requirements, it can be composited with aluminum foil glass fiber cloth (AG), aluminum foil (ALK), glass fiber cloth (GF) and other veneer materials.
