Titanium Threaded Flanges, also known as screwed flanges, are designed to connect to pipes without welding, by threading the internal bore to match external pipe threads. These flanges are ideal for low-pressure piping systems where welding is not feasible or desirable, especially in hazardous environments or high-purity applications.
Made in accordance with ASTM B381, titanium threaded flanges offer exceptional corrosion resistance, especially against seawater, acids, chlorides, and oxidizing chemicals.
Visual Inspection |
To check for surface defects such as cracks, dents, scratches, and deformations. |
Dimensional Inspection |
Verify outer diameter, thickness, bolt circle diameter, sealing surface dimensions, etc. |
Chemical Composition Analysis |
Performed by spectrometer or ICP to ensure the titanium grade (e.g., Gr.2, Gr.5) complies with standards. |
Mechanical Properties Testing |
Includes tensile strength, yield strength, elongation, etc., according to ASTM B381 or relevant standards. |
Non-Destructive Testing (NDT) |
Typically includes Ultrasonic Testing (UT) or Dye Penetrant Testing (PT) to detect internal or surface flaws. |
Pressure Testing (Hydrostatic Test) |
For pressure applications, hydrostatic testing may be conducted to verify strength and sealing performance. |
Sealing Surface Flatness Check |
Checks the smoothness and flatness of the sealing face (e.g., RF, FF) to ensure tight sealing. |
Hardness Testing |
Brinell or Vickers hardness testing to assess material condition or heat treatment if required. |
Tests are based on standards such as ASTM B381, ASME B16.5, GB/T 9119, EN 1092-1, etc.
Third-party inspection reports (SGS, TUV, BV) can be provided upon request.
