Titanium Products In Chemical Field
One of the remarkable characteristics of titanium is its strong corrosion resistance. Titanium can spontaneously form a dense and stable oxide film in many chemical media. This oxide film (TiO₂) gives titanium excellent corrosion resistance. Fortunately, titanium can form a passivation oxide film on the surface in most aqueous solutions. This allows it to remain stable in highly corrosive environments such as sulfuric acid, hydrochloric acid, nitric acid, sodium hydroxide solution and various salt solutions. The following are common titanium products in the chemical field.

Titanium anodes can decompose pollutants in electrolytic wastewater treatment. In addition, coating different catalytic coatings on the surface of titanium anodes can further improve the catalytic activity of titanium anodes.
Titanium Valves
Titanium valves play a role in controlling fluid flow, pressure and flow direction in chemical pipeline systems. They will not pollute the high-purity chemicals being transported. They can work reliably in various corrosive media.
Titanium Heat Exchanger
Heat exchangers are used for heating, cooling or condensing in chemical production. In acidic media such as seawater desalination and petrochemicals, titanium heat exchangers can significantly improve heat exchange efficiency.
Titanium Pumps
Titanium pumps are used to transport various corrosive liquids, avoiding leakage and failure caused by corrosion of the pump body. The impeller and pump body have high wear resistance and mechanical strength.
Titanium Pipe Fittings
Titanium pipe fittings include elbows, tees, reducers, etc. In pipeline systems that transport corrosive media, the application of titanium pipe fittings ensures the sealing and stability of the entire pipeline system.
Titanium Reactors
Titanium reactors often involve highly corrosive raw materials and complex chemical reactions. Titanium reactors can provide a safe and stable environment for chemical reactions with their excellent corrosion resistance.

CNC Machining Titanium Parts
Wstitanium is equipped with advanced CNC machining centers, ranging from high-precision lathes to multi-functional milling machines, ensuring that it can meet the diverse needs of different customers for titanium parts. CNC machining can achieve extremely high machining accuracy, which can generally be controlled at ±0.001mm or even higher, which is essential for the manufacture of titanium parts in the chemical field that have strict requirements on part size accuracy. High-precision parts can ensure the sealing and matching accuracy of chemical equipment, and improve the overall performance and reliability of the equipment.
CNC Milling
CNC milling can realize the manufacture of various complex-shaped parts, such as curved surfaces, special-shaped holes, threads, etc. This makes it possible to manufacture titanium parts with special structures in the chemical field
CNC Turning
Wstitanium has summarized the parameters suitable for turning titanium parts: low cutting speed (50-150m/min) to reduce heat; feed rate (0.05-0.3mm/r) to avoid part deformation; cutting depth (0.1-0.5mm) to ensure accuracy.
Forging Titanium Products
Forging is a manufacturing method that uses external force to plastically deform titanium billets to obtain products with certain shapes, sizes and mechanical properties. After forging, the grain structure inside the titanium product is refined and densified, and the distribution is more reasonable, which significantly improves the strength, toughness and fatigue performance. Compared with casting, forgings have higher density and better consistency of mechanical properties, and are particularly suitable for manufacturing key parts that withstand high loads and high stresses. For example, for reactors that need to withstand high pressure in the chemical field, the risk of rupture is reduced.
Wstitanium has deep technical accumulation and rich practical experience in the forging process of titanium parts in the chemical field. The structure of the parts is analyzed in detail, including shape, size, wall thickness, tolerance requirements, etc. For parts with complex shapes, they will be decomposed into multiple simple geometric shapes to facilitate the formulation of a reasonable forging process. There is a large residual stress inside the titanium parts after forging, and annealing is usually required. For example, for industrial pure titanium, an annealing temperature of 550-650℃ is generally used, and the furnace is cooled after 1-3 hours of heat preservation.
Casting Titanium Products
Casting is a manufacturing method that obtains castings with certain shapes, sizes and properties by pouring liquid titanium into a specific mold cavity and waiting for it to cool and solidify. Whether it is a small precision control valve part or a large chemical storage tank body. Wstitanium sets extremely high standards for the purity of titanium raw materials used for casting, requiring the titanium content to reach more than 99%. For small precision parts, high-purity titanium bars are usually selected as the starting material. For large and complex structural parts, high-quality titanium ingots may be used.
At the same time, fully consider the factors such as processing allowance, shrinkage rate and fluidity of liquid titanium in the casting process, accurately determine the size specifications of the raw materials, maximize material utilization and reduce manufacturing costs.
Welding Titanium Products
In the manufacture of titanium parts in the chemical field, welding has irreplaceable advantages and can achieve efficient connection of titanium parts. Welding titanium is a very challenging task. The melting point of titanium is as high as 1668℃, which means that sufficiently high energy needs to be provided to melt it during the welding process. Titanium is extremely chemically active at high temperatures and easily reacts with elements such as oxygen, nitrogen, and hydrogen in the air to form hard and brittle compounds, which sharply reduces the plasticity and toughness of the welded joint. For example, after titanium absorbs oxygen, it will form titanium oxide, which will increase the hardness and reduce the plasticity of the weld. Absorbing nitrogen will form titanium nitride, which will make the weld brittle.
Tungsten inert gas welding is one of the most commonly used methods for Wstitanium welding titanium. It uses a high-melting-point tungsten rod as an electrode, and under the protection of argon gas, the arc heat generated between the electrode and the weldment is used to melt the base material and filler metal (if necessary). It is suitable for welding titanium plates or pipes with a thickness of 0.5-6mm.
Finishing Services For Titanium Chemical Parts
In some cases, the surface of titanium still cannot fully meet the stringent requirements of chemical applications, such as higher corrosion resistance, wear resistance, and specific chemical activity. Therefore, it is very important to perform surface treatment on titanium parts, which can improve the performance of titanium parts and expand their application in the chemical field.
Pickling
The acid solution is used to react chemically with the oxides and impurities on the titanium surface, dissolving and removing them, thereby obtaining a clean surface. For example, hydrofluoric acid reacts with titanium oxide on the titanium surface: TiO₂ + 6HF = H₂[TiF₆] + 2H₂O. Case: In the manufacturing process of titanium heat exchangers, pickling is used to remove the rolling oxide scale on the surface of titanium tubes.
Anodizing
Using titanium as an anode, an external current causes an oxidation reaction on the titanium surface to form an anodic oxide film. The anode reaction is: Ti + 2H₂O – 4e⁻ = TiO₂ + 4H⁺ . Application case: In the chemical industry, the wear resistance and corrosion resistance of anodized titanium reactor stirring paddles are significantly improved, extending the service life.
Micro-arc oxidation
Use arc discharge to enhance the oxidation process of titanium surface. Instant high temperature and high pressure make the titanium surface form a thicker, denser and better-performing ceramic film layer, with a thickness of up to 1000-2000HV. The wear resistance and corrosion resistance of titanium seals treated by micro-arc oxidation can meet more demanding working conditions.
Physical Vapor Deposition (PVD)
PVD is to evaporate titanium or other metals, compounds, etc. into atoms or molecules by evaporation, sputtering and other methods under a high vacuum environment, and then deposit a layer of high hardness, good wear resistance and strong oxidation resistance on the surface of the titanium product, so that titanium parts can still work normally in harsh environments.
Chemical Vapor Deposition
Use gaseous metal compounds (such as titanium halides, organic titanium compounds, etc.) to react chemically on the surface of heated titanium parts to generate solid deposits and deposit on the surface to form a film layer. For example, when chemical vapor deposition of titanium nitride (TiN) thin film, the commonly used reaction is: TiCl₄ + 2H₂ + N₂ = TiN + 4HCl.
Thermal Spraying
The wire or powder spraying material (such as ceramic material) is heated to a molten or semi-molten state, and then atomized and sprayed onto the surface of the titanium part by a high-speed gas flow (such as an inert gas or plasma jet). These atomized particles solidify and accumulate to form a coating. Depending on the heat source, thermal spraying can be divided into flame spraying, arc spraying, plasma spraying, etc.
