Titanium flanges: connection pioneers in the petrochemical industry

July 13, 2022
Titanium flanges, as an indispensable connecting element in piping systems, provide reliable connection solutions for various industrial applications with their unique materials and excellent performance. In this article, the definition, structure, manufacturing methods, applications and advantages of titanium flanges will be introduced in detail.

I. Definition and structure
Titanium flanges are made of titanium or its alloys and are a component used to connect two or more tubes to each other at the end. It possesses excellent strength-to-weight ratio, corrosion resistance, non-magnetic and biocompatibility, and stability at high temperatures. Titanium flanges have through holes in the center of the disk-like structure matching the inner diameter of the tube, and the surface is distributed with a specific number, size and arrangement of eyelets for mounting bolts or double-headed studs to achieve a tight fixation between the flanges.
Second, manufacturing methods and connection forms

Titanium flanges are manufactured by various methods, including precision casting process, which is suitable for complex internal structure or special performance requirements. Connection form, in addition to the traditional bolt connection, also includes threaded connection and welding connection. Threaded connections are suitable for small or application-specific flanges, which can be threaded directly to pipes or other components. Welded connections, on the other hand, are particularly suitable for applications requiring extremely high sealing and structural strength, such as pressure vessels, chemical equipment or aerospace applications.

III. Applications and Advantages
Titanium flanges are widely used in piping systems in chemical processing, petroleum refining, ocean engineering, electric power, pharmaceuticals, food processing and other industries, and are particularly suitable for handling highly corrosive media. Its corrosion resistance, light weight, biocompatibility and high temperature performance make it a leader in high-performance pipeline connection parts.
1. corrosion resistance: the high corrosion resistance of titanium flanges enables them to maintain long-term structural integrity and sealing reliability in harsh environments, significantly reducing maintenance costs and extending equipment life.
2. Lightweight: Compared with traditional stainless steel or carbon steel flanges, titanium flanges have a lower mass, which is valuable for high-end applications that require weight reduction.
3. biomedical field: titanium's biocompatibility makes it popular in medical device manufacturing, can be used to build implanted medical devices or laboratory equipment piping connections.
4. High temperature performance: titanium alloy can still maintain good mechanical properties and creep resistance under high temperature environment, suitable for high temperature and high pressure working conditions.

Specification parameters and testing
The specification parameters of titanium flanges include nominal diameter, pressure level, flange type, connection form, applicable standards and material grade. In order to ensure that it meets the relevant standards and use requirements, the testing of titanium flanges may cover material composition analysis, dimensional inspection, non-destructive testing, mechanical properties testing, sealing performance test and surface quality assessment.
In conclusion, titanium flanges are indispensable high-performance pipeline connecting parts in modern industrial fields due to their unique material and excellent performance, which provide reliable connection solutions for a variety of harsh environments and demanding applications.Yesino provide Titanium Bar, Titanium Sheet, Titanium Plate, Titanium Forging and other titanium product.
