Application

Shell and Tube Heat Exchangers

Condensers:
In power plants and chemical plants, steam is condensed into liquid water. The U-shaped tube can expand freely to avoid thermal stress causing leakage at the tube sheet interface.

Evaporators:
Used for liquid vaporization in refrigeration and chemical processes, the U-shaped structure is compact and improves evaporation efficiency.

Oil Coolers/Process Fluid Heat Exchangers:
Cooling lubricating oil or process media in petrochemicals and ships, the pressure resistance of seamless tubes ensures safe operation.

Boiler Systems

Low-pressure boiler economizers:
Recover flue gas waste heat to preheat boiler feed water, and the thermal conductivity of low-carbon steel optimizes heat recovery efficiency.

Low-pressure superheaters:
Superheating low-temperature steam (usually ≤400°C), U-shaped elbows relieve thermal expansion stress.
