Introduction to the Application and Standardized Production Process of Large Diameter Titanium Flanges

Large diameter titanium flanges are the core connecting fittings for large industrial pipelines and complete sets of equipment. They are mostly made of TA2 pure titanium material and have advantages such as lightweight and high strength, acid and alkali corrosion resistance, high pressure resistance, and stable sealing. Compared to traditional carbon steel and stainless steel flanges, it has stronger adaptability to harsh working conditions and longer service life, and is widely used in large-scale engineering projects such as marine engineering, petrochemical industry, seawater desalination, and power energy.

In practical applications, large-diameter titanium flanges are mainly used for sealing connections of large pipelines, tower equipment, heat exchangers, and high-pressure pipelines. In the field of ocean engineering, it is suitable for offshore platforms and deep-sea equipment pipeline systems, and can resist corrosion from seawater chloride ions and salt spray; Equipment pipelines suitable for strong alkali and high temperature corrosion conditions in the chemical industry; It is also the preferred accessory for seawater desalination, wind power energy, and large-scale environmental protection equipment, effectively solving problems such as leakage, aging, and corrosion of large-diameter pipelines, and ensuring long-term stable operation of equipment.

The production process of large-diameter titanium flanges is rigorous, and the entire process follows the industry standards of GB/T and ASTM B381. The overall process includes eight core processes: raw material selection, precision cutting, high-temperature forging, ring rolling forming, heat treatment, CNC precision machining, surface treatment, and non-destructive testing. Based on the characteristics of large diameter products, a dedicated rolling process is adopted to ensure roundness and structural strength; Eliminating residual stresses in forging through annealing treatment, improving toughness and stability. Finally, through precision turning of the sealing surface, acid pickling and passivation, and non-destructive testing, porosity and crack defects are eliminated to ensure that the product meets the standard for compressive sealing performance.

Shaanxi Qianyi Tuoda Technology Co., Ltd. specializes in producing customized large-diameter titanium flanges and national standard and American standard TA2 titanium flanges, supporting non-standard size and special process customization, with strict quality inspection throughout the process. The products have high precision, good sealing, corrosion resistance and durability, and can meet the construction needs of various large-scale industrial projects. There is sufficient stock and stable supply.
