Performance characteristics: The performance of steel sleeve prefabricated buried insulation pipes is excellent, with the core being excellent sealing and moisture resistance. The outer protective steel pipe ensures that the insulation layer is dry for a long time, and the insulation effect is stable. The pipeline has high pressure bearing capacity and can directly withstand external soil loads. The high temperature resistance is particularly outstanding, and it can transport media such as high-temperature steam. Adopting a sliding structure design (divided into internal sliding and external sliding), it can effectively release thermal stress, adapt to the thermal expansion and contraction of pipelines, and has high safety and reliability.

Application scenarios: Internal sliding type: suitable for applications with high insulation requirements and small pipeline footprint, including petroleum, chemical, power, thermal, urban heating and other fields.
External sliding: long-distance transportation of high-temperature steam, petrochemical industry, power industry, temperature control industry.
