Baoji City Lihua Non-ferrous Metals Co., Ltd., abbreviated as Lihua Titanium Industry, was established in 2006. Leveraging the industry advantages of Baoji and its own strong technical support, the company has been dedicated to the production and sales of titanium and other non-ferrous metals for many years.
In the "chemical battlefield" of the chlor-alkali industry, where a constant struggle against strong corrosive media is waged, ensuring the safety of every connection point is the lifeline for the long-term stable operation of production. Over the past two decades, Lihua Titanium Industry has remained focused on this, dedicated to becoming an expert in the field of titanium flanges. Combating corrosion not only requires excellent materials but also demands extreme focus and reliable manufacturing.
The chlor-alkali industry primarily produces caustic soda, chlorine gas, and hydrogen gas, and its production process involves the widespread presence of various highly corrosive media:
| Chlorine environment |
Both dry chlorine and more corrosive wet chlorine have strong oxidative corrosion on most metals. |
| Hydrochloric Acid Environment |
Hydrochloric acid environments with different concentrations and temperatures are typical strong acid corrosion environments. |
| Chloride Solutions |
Such as brine, chlorate, etc., are prone to cause pitting corrosion and stress corrosion cracking. |
| High-temperature alkaline solution |
Concentrated alkaline solution is also corrosive to many materials at high temperatures. |
In this "chemical battlefield," traditional 304 and 316 stainless steel flanges struggle to resist corrosion for long periods, often leading to corrosion penetration and seal failure, resulting in medium leakage. This not only causes production material losses and environmental pollution but may also trigger serious safety accidents, and shutdowns for replacement also bring significant economic losses.
Facing this severe challenge, the industry has found a reliable solution—titanium, which has demonstrated near-perfect compatibility.
Corrosion Resistance: Titanium can instantly form a dense, stable oxide film (TiO₂) in oxidative media, which has an extremely strong self-healing ability. In wet chlorine gas, chlorine water, hypochlorite, and chloride solutions, its corrosion resistance is far superior to stainless steel and even exceeds that of certain precious metals. Particularly in chlorine-containing environments, it almost does not produce pitting or crevice corrosion.
Mechanical Properties: Titanium material has a high specific strength (strength-to-density ratio), which can ensure the strength of the flange structure while achieving lightweighting, helping to reduce the load on the pipeline system.
Thermal Stability: Titanium materials maintain stable performance and high reliability within the temperature range involved in chlor-alkali processes.
The inherent advantages of titanium metal must ultimately be translated into every robust connection in the pipeline system. This is precisely the field that Lihua Titanium Industry has continuously deepened over the past two decades. We specialize in transforming high-quality titanium materials through exquisite forging and machining processes into superior performance titanium flanges, ensuring their corrosion resistance and mechanical strength are fully realized under harsh conditions.
duction, the value of titanium flanges is particularly prominent:
| Saltwater Purification and Electrolysis Section |
In wet chlorine gas pipelines, anode liquid systems, and dechlorination systems, titanium flanges can effectively resist the corrosion of chloride ions and hypochlorous acid, ensuring the safe and stable operation of electrolyzers. |
| Chlorine Treatment and Compression Section |
Core equipment such as metal anode electrolyzers, ion membrane electrolyzers, and anode liquid pumps all require titanium components. |
| Hydrochloric Acid Synthesis Section |
In pipelines handling hydrogen chloride gas and hydrochloric acid media, the service life of titanium flanges far exceeds that of other metal flanges. |
Corrosion is the eternal adversary of the chlor-alkali industry, and choosing the right protective material is the key to winning this long battle. At every vulnerable connection point in the pipeline system, Lihua Titanium's titanium flanges are building a strong defense with their excellent corrosion resistance and the quality of precision manufacturing.
In the chlor-alkali industry, correctly selecting titanium material is particularly important for ensuring the safety, stability, and long-term operation of equipment. Different grades of titanium material each have their own characteristics, suitable for different working condition scenarios:
|
TA1 (Gr.1) |
TA2 (Gr.2) |
TA9 (Gr.7 / Ti-0.2Pd) |
| Core Features |
Optimal plasticity and toughness, relatively lowest strength |
Most balanced comprehensive performance, excellent in strength, plasticity, and corrosion resistance |
Adding about 0.12%-0.25% palladium (Pd), corrosion resistance takes a leap |
| Tensile strength |
≥ 240 MPa |
≥ 400 MPa |
Compared to TA2, corrosion resistance is greatly improved |
| Typical application scenarios |
Components with complex shapes requiring deep cold stamping; parts for atmospheric or low-pressure environments with operating temperatures not exceeding 80°C, such as those in dilute alkaline solutions or saltwater storage tanks |
The workhorse in chlor-alkali production, suitable for most room temperature to medium temperature (approximately 150℃) conditions, such as flanges, pump casings, and valve bodies in saltwater sections, electrolyte pipelines, and wet chlorine gas pipelines |
High-temperature, high-concentration, acidic, or reducing media; areas with dead zones or prone to crevice corrosion (such as gaskets for flanges); critical equipment with complex and fluctuating medium composition |
As a company specializing in titanium flange manufacturing for nearly two decades, Lihua Titanium deeply understands the extreme pursuit of equipment reliability in the chlor-alkali industry. With solid craftsmanship, strict management, and honest service, we ensure that every titanium flange leaving our factory embodies our dedication and craftsmanship, becoming the most trustworthy "safety guardian" in pipeline systems.
Make connections more reliable, make production safer. Lihua Titanium Industry, specializing in flanges for twenty years, is willing to work with you to overcome difficulties and create a green, efficient, and safe future.
