Long pipes with excellent cost reduction, construction feasibility, heat resistance, and durability characteristics.
"CALPEX" is a long pipe composed of cross-linked polyethylene pipes as conduits, excellent rigid polyurethane foam as insulation material, and an outer pipe made of corrugated low-density polyethylene, all constructed from corrosion-resistant materials. By effectively combining the various physical properties of the materials and their structure, it achieves excellent seismic resistance through characteristics of "lightweight," "long length," and "flexibility," while also enabling labor-saving and improved durability in the piping system. [Features] - Corrosion-resistant materials - High thermal insulation properties - Flexible corrugated outer pipe - Mechanical strength - Reduction of connection points, etc. *For more details, please download the PDF or feel free to contact us.
