Steel Sleeve Steel Steam Insulated Steel Pipes are high-temperature piping systems consisting of an inner steam-transporting steel pipe, a thermal insulation layer (e.g., rock wool, aerogel), and an outer protective steel sleeve, engineered for efficient steam transport. They are widely used in power plants (boiler steam lines), district heating networks, and industrial facilities (paper, chemical) that require long-distance transport of high-temperature steam (200–400°C).
A core advantage of Steel Sleeve Steel Steam Insulated Steel Pipes lies in their superior heat retention and structural durability. The multi-layer insulation minimizes heat loss (thermal conductivity ≤0.04 W/(m·K)), ensuring steam maintains temperature and pressure over kilometers, while the outer steel sleeve resists external impacts, soil corrosion, and moisture—critical for underground or outdoor installations. This design also prevents insulation damage from high-temperature expansion.
Steel Sleeve Steel Steam Insulated Steel Pipes further offer stability for extreme conditions. The inner steel pipe withstands high pressure (up to 10 MPa) and thermal stress, with expansion joints accommodating temperature-induced length changes. They comply with standards like GB/T 29460, ensuring compatibility with steam systems. Whether used in cross-city heating pipelines or power plant steam transmission, they deliver reliable, low-energy-loss performance for high-temperature media.
