Xingbang's Steam Pipeline Insulation is a thermal insulation system designed for high-temperature steam transport pipelines, suitable for sectors such as petrochemicals, power generation, and district heating. The system utilizes high-temperature resistant materials-such as rock wool, calcium silicate, or aerogel-paired with a metal or HDPE outer jacket to meet insulation requirements for steam pipelines operating between 150°C and 650°C. Xingbang offers options for either factory-prefabricated pipe sections or on-site insulation application, ensuring uniform insulation thickness and consistent quality, while allowing for the customization of insulation structures and thicknesses based on specific operating conditions.

Product Advantages
Wide temperature resistance range
Steam Pipeline Suitable for operating temperatures ranging from 150°C to 650°C, covering the primary operating conditions for industrial steam.
01
Energy-efficient
Optimized insulation structure design reduces heat loss by approximately 40% compared to traditional solutions.
02
Waterproof and corrosion-resistant
The outer protective layer forms a complete seal, effectively preventing groundwater infiltration and corrosion under the insulation (CUI).
03
Convenient installation
Factory-prefabricated pipe sections require only joint treatment on-site, significantly shortening the installation period.
04
Long service life
With proper material selection and standardized installation, the service life can reach 25–30 years.
05
Applications
Steam transmission networks for petrochemical enterprises
Boiler steam piping in thermal power plants
High-temperature steam trunk lines for municipal district heating
Centralized steam supply systems for industrial parks
FAQ
Q: How is Corrosion Under Insulation (CUI) prevented?
A: Xingbang employs multiple measures to effectively block moisture ingress and prevent CUI, including waterproof sealing of the outer protective layer, anti-corrosion coating on the outer wall of the steel carrier pipe, and a comprehensive joint sealing process.
Q: How should joints in steam pipeline insulation be handled to ensure effective thermal insulation?
A: Joints are sealed using the same insulation material as the pipe body, combined with an outer sleeve seal, ensuring consistent insulation performance across the entire pipeline.
