I. Product Applications
1. A load-bearing support component designed for high-temperature heating pipelines, steam lines, and chemical process pipelines, carrying the pipe dead weight, medium load, and displacement loads caused by thermal expansion and contraction;
2. The built-in thermal insulation layer blocks heat transfer from the pipeline to the steel support structure, helping prevent high-temperature deformation, reduce heat loss, and improve energy efficiency;
3. Suitable for high-temperature composite pipelines in power plants, refineries, vessels, urban heating networks, and offshore platforms;
4. Used together with U-bolts and fasteners to secure weld-overlay composite pipes and lined composite pipelines, preventing vibration and displacement during operation.

III. Material and Operating Condition Selection
1. Coated carbon steel with a vermiculite insulation core: suitable for heating pipelines in power plants and indoor high-temperature steam lines in refineries;
2. Hot-dip galvanized carbon steel with an aluminum silicate insulation core: suitable for high-temperature pipelines in coastal chemical parks, ship decks, and offshore platforms, with resistance to salt-spray corrosion;
3. All-stainless-steel insulated pipe supports: suitable for seawater desalination systems and highly corrosive, high-temperature composite pipelines.
IV. Core Product Advantages
1. The insulated sandwich structure interrupts thermal bridging, significantly reduces pipeline heat loss and energy consumption, and protects the supporting steel structure from high-temperature damage;
2. The three-clamp wraparound structure distributes loads evenly, provides stable support for large-diameter pipelines, and effectively limits operational vibration and lateral displacement;
3. The fully welded base offers high rigidity, settlement resistance, and wind-load resistance, making it suitable for continuous support of long-distance high-temperature pipelines;
4. The internal insulation material offers high-temperature resistance, high compressive strength, and resistance to pulverization, helping prevent collapse or performance failure during long-term use;
5. Can be supplied together with weld-overlay composite pipes, composite flanges, and stainless steel fasteners to form a unified corrosion-protection system and reduce galvanic corrosion;
6. Nominal diameter, installation height, and load capacity can all be customized to suit high-temperature pipeline applications in land-based plants, ocean-going vessels, and offshore platforms.
