Titanium steel composite plate: The "anti-corrosion armor" of the pressure vessel industry.

In concentrated sulfuric acid boiling reactors, desulfurization chimneys in high-humidity, corrosive environments, and deep-sea oil and gas platform equipment, a composite material consisting of a titanium and steel base layer is the ultimate solution for pressure vessels against extreme corrosion. It can withstand hundreds of atmospheres of pressure and corrosive media that even stainless steel finds difficult to resist, while costing only one-third as much as pure titanium equipment. It can withstand corrosive media and is only one-third the cost of pure titanium equipment.

Performance Advantage: A low-cost solution to the problem of high corrosion.

The core value of the titanium steel composite plate lies in its complementary materials:
Titanium compound layer (TA1/TA2): Resistant to strong acids (such as concentrated sulfuric acid and acetic acid) and seawater corrosion. The annual corrosion rate is less than 0.001 mm, which is far better than stainless steel (such as 316L, which perforates in wet chlorine gas in only two years).
 The steel base (Q345R/16MnR) provides structural strength and a pressure-bearing capacity of more than 3.5 MPa at a cost of one-eighth that of titanium.
The composite interface uses metallurgical bonding through explosion welding with a shear strength of more than 300 MPa to ensure zero media penetration.

Application scenario: "Invisible Defender" on the battlefield of corrosion.

1. Chemical Equipment: Survival in a Strong Acidic Environment
 PTA (purified terephthalic acid) plant: A 1000 m² large-scale oxidation reactor condenser with a titanium composite layer that resists mixed corrosion from acetic acid and bromide at 180°C.

2. Electric power and environmental protection: Anti-corrosion revolution of the desulfurization chimney.
Flue gas after wet desulfurization contains corrosive substances, such as SO₃ and Cl⁻. The titanium-steel composite plate chimney inner tube: It has a life span three times longer than an FRP coating solution and an overall cost that is 40% lower.

3. New Energy and Marine Engineering
 LNG storage tanks have a titanium composite layer that resists the embrittlement and corrosion caused by -162°C liquid natural gas and hydrogen sulfide. The maintenance cycle has been extended from six months to five years.
 Desalination Equipment: The high-pressure pump shells are made of an exploded composite plate and are 50 times more resistant to chlorine-ion corrosion than stainless steel.
