Titanium Butt Welding Neck Flanges

Product Description

Titanium weld neck flanges are high-strength piping components designed for high-pressure and high-temperature pipeline systems. The weld neck design provides excellent structural integrity by transferring stress from the flange base to the pipe, making it suitable for critical industrial applications.

These flanges are manufactured according to international standards such as:

• ASME International – ASME B16.5

• ANSI, JIS, DIN and other international standards
