Xingbang's industrial insulated piping system is designed for sectors such as petroleum, chemicals, power generation, and pharmaceuticals. It is suitable for transporting high-temperature, high-pressure media-including steam, hot oil, and chemical gases-across an operating temperature range of -50°C to 350°C. The product line includes polyurethane-insulated pipes (for temperatures ≤140°C) and "steel-casing-steel" steam-insulated pipes (for 150°C–350°C); the latter features a multi-layer composite insulation structure that reduces heat loss by over 40% compared to conventional piping. Optional smart monitoring systems are available to pinpoint leak locations in real-time, and the pipes support both direct-burial and above-ground installation methods. These systems are currently widely used in centralized steam supply projects for petrochemical, power, and industrial parks across more than 130 cities domestically and internationally.

FAQ
Q: What is the service life of the industrial insulated pipe?
A: Under normal operating conditions, the industrial insulated pipe is designed for a service life of over 30 years. Xingbang's products have passed 30-year aging tests; the outer casing utilizes 3PE or fusion-bonded epoxy anti-corrosion coatings, making it suitable for various corrosive soil environments.
Q: How is insulation performance maintained without degradation during high-temperature operation?
A: A multi-layer composite gradient insulation structure is employed, where materials work in concert to prevent failure associated with single-material use at high temperatures. An aluminum foil reflective layer is added between key layers to effectively reduce radiant heat loss. High-quality rigid polyurethane foam with a closed-cell rate exceeding 88% ensures a consistently low thermal conductivity over the long term.
Q: How are leaks in the pipe network detected and located?
A: Xingbang industrial insulation pipes can be equipped with built-in leak detection wires or fiber-optic monitoring systems. In the event of a leak, the monitoring system can rapidly pinpoint the location, facilitating timely repairs and eliminating the need for large-scale excavation to locate the issue, thereby significantly reducing maintenance costs.
