Fire-Resistant Industrial Rock Wool Pipe

Description Review

Description

1. Product Description

SUNTHERM Industrial Insulation Rock Wool Pipes (SUN Series) are made by molding rock wool fibers into pipe shells, followed by high-temperature curing and forming. For easy installation, the pipes feature a single longitudinal slit along the shell axis, ensuring a tight fit with the insulated pipeline. The outer surface of the pipe can be finished to ensure uniform insulation thickness. Low-chloride products can be produced upon request. Depending on application requirements, the pipes can be laminated with facing materials such as aluminum foil fiberglass cloth (AG), aluminum foil (ALK), or fiberglass cloth (GF).
