Product Overview
Explore our core polyurethane insulation solutions for industrial and project applications.
Polyurethane pipe supports are load-bearing insulation supports made of high-compressive-strength polyurethane or PIR insulation material with external metal components.
They are used not only as pipe support structures, but also as part of the insulation system. Compared with traditional wooden pipe supports, polyurethane pipe supports provide better insulation performance, longer service life, higher dimensional stability, and easier installation.
The product can be designed as sliding supports, guide supports, fixed supports, limit supports, multi-directional supports, U-type supports, trunnion insulation blocks, and high-temperature steam pipe supports according to pipeline layout and engineering requirements.
