Titanium Flange

Titanium flanges are piping components made from titanium or titanium alloys that securely join two pipes together using bolts to create a seal. Characterized by a density of approximately 4.5 g/cm³, exceptional corrosion and high-temperature resistance, and non-magnetic properties, they are ideally suited for use in corrosive environments such as those involving seawater or nitric acid. Common materials include commercially pure titanium (grades TA1 and TA2) and titanium alloy (grade TC4). Structurally, they consist of a flange body, a gasket, and fasteners (bolts and nuts), with sealing face configurations such as raised face (RF) and tongue-and-groove (TG). They are classified by structure into types such as integral, weld-neck, and lap-joint, and are widely used in the chemical, marine, and aerospace industries. Manufacturing involves casting, forging, welding, and heat treatment processes, with products required to meet standards such as GB/T9112 and ASME B16.5; surfaces typically undergo forging or machining (turning).

Application：

1. Highly Corrosive Environments: In sectors such as chlor-alkali chemicals, environmental wastewater treatment, and lithium-ion new energy projects, titanium flanges withstand strong acids, strong alkalis, chlorine gas, and fluorine-containing media, thereby resolving issues with stainless steel flanges that are prone to corrosion and leakage.
2. Marine and Shipbuilding: titanium alloy flange used in seawater desalination and marine piping systems; titanium’s resistance to seawater corrosion and its non-magnetic properties make it ideal for marine vessels and offshore engineering.
3. High-End Manufacturing and Medical: titanium alloy flange the aerospace industry leverages its high strength and high-temperature resistance, while the medical device sector utilizes its biocompatibility—ensuring no heavy metal ion leaching and preventing material contamination.
4. Other Industrial Applications: titanium alloy Flange widely used in fields such as hydrometallurgy, petroleum, pharmaceuticals, and sports equipment, particularly in applications requiring high structural strength and corrosion resistance.
