1、 Extreme corrosive environment application

1. Chemical production process

Strong acid medium treatment:

Corrosion resistance of ultra stainless steel in sulfuric acid/hydrochloric acid production equipment is 10 times higher, and the service life is extended by more than 3 times;

The lining of the PTA reactor is resistant to acetic acid corrosion at a rate of less than 0.01mm/year.

Key scenarios:

Chlor alkali industry electrolytic cell radiator (resistant to wet chlorine gas corrosion);

High temperature flue gas waste heat recovery of petrochemical cracking unit (temperature resistance ≥ 500 ℃).

2. Ocean and salt spray environment

The condenser of the seawater desalination device has a lifespan of 20 years against chloride ion corrosion;

Ship engine exhaust heat recovery system, no pitting corrosion in salt spray environment.

2、 High temperature and high pressure scenarios

Petroleum refining: hydrogenation reactor heat exchange unit, pressure bearing capacity ≥ 15MPa, hydrogen embrittlement risk approaching zero;

Geothermal development: Geothermal fluid heat exchanger, resistant to hydrogen sulfide corrosion, with a 35% increase in heat exchange efficiency;

Nuclear power: auxiliary cooling system with excellent resistance to radiation creep.

3、 Efficient and energy-saving features

1. Breakthrough in heat transfer efficiency

The fin winding structure increases the heat transfer area by 15-20 times that of the light tube, and the turbulence effect enhances the heat transfer coefficient by 40%;

The thermal conductivity of titanium material is equivalent to that of stainless steel, but its corrosion resistance achieves zero maintenance cost;

2. Energy saving and consumption reducing data

The chemical waste heat recovery system adopts titanium finned tubes, reducing energy consumption by 18-22% (compared to the carbon steel scheme);

Each ton of TA2 titanium tube reduces CO2 emissions by 14 tons throughout its entire lifecycle (with a smelting energy compensation period of less than 3 years).

4、 Irreplaceability analysis

Stainless steel: increased resistance to chloride ion corrosion by 8 times, eliminating frequent replacement costs in coastal factories;

Carbon steel coating: no risk of coating peeling, maintenance free, reducing maintenance costs by 60%;
