Recently, Baoji Fairy Titanium Industry Co., Ltd. successfully completed the production of a batch of titanium dish ends, which have been smoothly delivered to the customer's site. The delivered titanium dish ends include multiple models such as elliptical and dished heads, and will be used in chemical projects. As a key pressure-bearing component of pressure vessels, the performance of titanium dish heads directly affects the safety and service life of the entire equipment. The customer placed stringent requirements on product quality, delivery cycle, and quality traceability system. Facing the dual challenges of high technical difficulty and tight delivery cycle, the company's production and quality inspection teams worked closely together, strictly implementing full-process quality control from material inspection to finished product delivery, ensuring that all product indicators met the GB/T 25198 standard and the customer's technical specifications, ultimately successfully completing the delivery task.
I. Core Characteristics of Titanium Dish Heads
Titanium dish heads are pressure vessel heads made of titanium or titanium alloys, mainly used in chemical, marine, aerospace, and other fields with high requirements for material performance. Their core characteristics are mainly reflected in the following five aspects:
Excellent corrosion resistance. Titanium and its alloys exhibit excellent performance in various corrosive media, particularly seawater and chloride ion corrosion, and demonstrate superior stability in harsh environments such as strong acids and alkalis. This characteristic makes titanium dish heads irreplaceable in chemical reactors, seawater desalination equipment, and marine engineering equipment. Titanium-steel composite heads combine the corrosion resistance of titanium with the structural strength and cost-effectiveness of carbon steel, making them particularly ideal for pressure vessels handling highly corrosive media such as acids and chlorides.
High strength and lightweight are combined. Titanium alloys have extremely high specific strength, low density, and strength approaching that of steel, effectively reducing the overall weight of equipment while ensuring structural strength. Pure titanium (Gr1/Gr2) possesses excellent comprehensive properties, while titanium alloys (such as Gr12/Ti-0.3mo-0.8ni) can achieve tensile strengths exceeding 620MPa and exhibit high-temperature resistance, making them suitable for applications requiring both high strength and lightweight design.
Outstanding high-temperature resistance. Titanium alloys maintain excellent mechanical properties and creep resistance even at high temperatures, making them widely used in high-temperature environments such as petroleum refining reaction equipment, nuclear power cooling systems, and geothermal power generation units.
They exhibit excellent biocompatibility. Titanium is non-toxic and highly biocompatible, making it suitable not only for medical equipment requiring high cleanliness but also for components in medical implants.
They offer strong sealing reliability. As end caps on pressure vessels, end caps are a primary pressure-bearing component. Connected to the vessel body by welding, they are non-removable and provide a reliable seal, ensuring safe operation of the equipment under high pressure.
II. Application Areas of Titanium Dish Heads
Titanium end caps, due to their superior performance, are widely used in several high-end manufacturing fields.
Chemical Industry. The chemical industry is one of the largest application markets for titanium end caps, primarily used in critical equipment such as reactors, storage tanks, heat exchangers, and piping systems. Titanium end caps are resistant to corrosive media such as strong acids and alkalis, significantly extending equipment lifespan and reducing maintenance costs. According to statistics, the penetration rate of titanium-steel composite heads in the chemical equipment field reached 65% in 2025, demonstrating a clear trend of domestic substitution.
In the marine engineering field, the high salinity and corrosiveness of the marine environment pose stringent challenges to equipment materials. Titanium dish heads are used in seawater desalination equipment, submarine pressure hulls, and ship components, exhibiting excellent resistance to seawater corrosion and ensuring long-term stable operation of equipment in saline environments.
In the energy industry, titanium dish ends are widely used in key equipment such as high-temperature reaction equipment, nuclear power cooling systems, and geothermal power generation devices due to their high-temperature resistance and resistance to hydrogen sulfide corrosion.
With the continued growth in demand from downstream high-end manufacturing sectors such as chemical, aerospace, and marine engineering, the market prospects for titanium dish heads are broad. The company will continuously improve its technical level and service capabilities to meet the diverse needs of customers with higher-quality products and more professional services. In the future, the company will continue to deepen its expertise in the field of special material heads, continuously promote technological upgrades and process optimization, and create greater value for customers.
