Geothermal Steel-Plastic Pipes

Composite pipelines engineered for geothermal hot water and district heating. Steel for strength, plastic lining for corrosion resistance—ideal for brine, hot water transfer and greenhouse heating networks.

• Construction: Carbon steel casing with corrosion-resistant plastic liner (e.g., PE-RT/PP-R) and internal epoxy options
• Performance: High temperature/pressure capability (project-specific PN & temperature ratings)
• Joints: Butt-welded, flanged or grooved couplings; leak-test ready
• Protection: External coating options; cathodic protection compatibility
• Sizes: Typical DN ranges for geothermal networks (verify on product pages)
• Applications: District heating, greenhouses, process hot water, wellhead lines
