ASTM B381 Grade 2 Grade 5 Grade 7 Titanium Flanges ASTM  Plate Flange Raised Face Titanium for Piping Systems

Titanium flanges are essential industrial components widely used in applications requiring the connection and sealing of pipes or equipment. They are commonly used to connect pipelines, valves, pumps, and other equipment, providing convenience for disassembly and reinstallation when needed. Made from titanium metal, titanium flanges offer excellent strength, lightweight properties, and exceptional corrosion resistance, making them the preferred choice in applications that require high strength, lightweight materials, and superior performance in extreme environments. Titanium flanges are primarily used in aerospace, chemical processing, oil and gas, and medical fields, with particular emphasis in aerospace, chemicals, oil and gas, and biomedical applications.

Test Certificates for Titanium Pipe Flanges:

Manufacturer's Test Certificate (TC) according to EN 10204/3.1B:

• This certificate indicates that the titanium pipe flanges have been tested and verified in accordance with EN 10204/3.1B. The 3.1B certification means that the material has been tested by the manufacturer and the test results are based on the manufacturer's own inspection and testing, which is provided to the buyer.

Raw Materials Certificate:

• This document confirms that the raw materials used for manufacturing the titanium pipe flanges meet the necessary chemical and mechanical properties as per the applicable standards, ensuring material traceability.

100% Radiography Test Report:

• This report confirms that the titanium pipe flanges have been subjected to 100% radiography (X-ray inspection) to detect any internal defects, such as cracks, voids, or inclusions. It ensures the structural integrity and quality of the flange.

Third Party Inspection Report:

• This report is issued by an independent third-party inspection agency. It verifies that the flanges have been tested and meet the required specifications and standards. Third-party inspections add an additional layer of reliability and trust for the buyer.

EN 10204 3.1 Certificate:

• The EN 10204 3.1 certificate provides verification that the product meets the technical specifications and the required mechanical properties. It ensures that the products conform to the relevant European standards and regulations.

Additional Requirement: NACE MR 01075:

• NACE MR 01075 is a standard published by the National Association of Corrosion Engineers, which defines requirements for materials used in sour service environments. If requested, this certificate ensures that the titanium pipe flanges are suitable for use in environments with hydrogen sulfide (H2S), where corrosion resistance is critical.

Ferrite Content Certificate (if requested):

• Some applications may require a specific ferrite content to ensure the material's suitability for certain welding processes or environments. This certificate ensures the ferrite content complies with the required standards.

Applications of Titanium Flanges include:
 
Aerospace: Titanium flanges are widely used in the aerospace industry, particularly in engines, airframes, and other critical systems due to their lightweight, strength, and corrosion resistance.
Chemical Processing: In chemical plants, titanium flanges are used to connect reactors, heat exchangers, and piping systems, as they can withstand high temperatures and aggressive corrosive environments.
Power Generation: Titanium flanges are used in nuclear reactors, thermal power plants, gas turbines, and other equipment due to their excellent high-temperature resistance and durability.
Oil and Gas: In offshore drilling, refineries, and pipeline systems, titanium flanges are ideal due to their resistance to saltwater corrosion and high-temperature endurance.
Medical Applications: Titanium flanges are used in biomedical fields, such as implants, prosthetics, and surgical devices, due to their biocompatibility and resistance to body fluid corrosion.
