Flue

Key features:

• High strength, tight sealing: Continuous welding with NDT; high‑temp gaskets at flanges and manholes; no gas leakage.

• Heat & corrosion resistant: Carbon steel, heat‑resistant steel, or refractory lining; anti‑corrosion coating (glass flake, acid mortar) or alloy liner for sulfur‑containing gas.

• Reliable thermal compensation: Bellows or slip‑type expansion joints absorb axial, lateral, and angular expansion.

• Easy inspection & cleaning: Quick‑open manholes, cleanout ports, and test ports.

• Good thermal insulation: Rock wool or ceramic fiber with metal cladding reduces heat loss and prevents burns.

• Low resistance design: Optimized bend radius and guide vanes reduce pressure drop, saving fan power.

• Proper supports & hangers: Spring hangers, rigid hangers, or sliding supports for uniform stress.

Applications: Power plant coal/gas boiler flues; industrial oil/gas boilers; metallurgical heating/furnace flues; chemical incinerator exhaust; waste‑to‑energy plant gas cleaning systems.
