Grade: Gr2, Gr5, Gr7, Gr9, Gr12
Standard: ASME B16.5
Materials Standard: ASTM B381, ASTM B348, ASTM B265
Type: Titanium weld neck flange
Processing: Forging, Rolling
Inspection: UT, X-Ray RT, PT
ISO9001 approval, Mill Test Report
Products advanatges
Weld neck structure: The long, tapered weld neck ensures a continuous stress transition between the flange and the pipe, reducing stress concentration in the weld.
Multiple titanium grades: Available in Gr.2 / Gr.5 / Gr.7 / Gr.9 / Gr.12, conforming to ASTM B381 / B348 / B265.
Forged/rolled forming: Utilizing forging or rolling processes, resulting in uniform grain size and fewer internal defects.
High dimensional accuracy: Sealing surfaces and bolt holes are machined to ASME B16.5; excellent assembly concentricity reduces the risk of leakage due to deviations.
Production Process
Raw Materials: Titanium and titanium alloy raw materials undergo incoming inspection to ensure composition and properties meet ASTM requirements.
Forming: Forging or rolling to ensure continuity of the weld neck and flange body structure.
Machining: CNC machining of sealing surfaces, end faces, and bores to ensure dimensional consistency.
Surface Treatment: Pickling or cleaning to meet welding and usage requirements.
Inspection: Dimensional inspection + ultrasonic testing; radiographic testing available upon request.

FAQ
Q: What type of flange is this?
A: Welded neck flange, used for butt-welded connections, with a higher pressure resistance than slip-on flanges.
Q: Can it be used in high-pressure conditions?
A: Yes, the welded neck structure reduces stress concentration, making it suitable for high-pressure and temperature-fluctuating environments.
Q: Is it resistant to seawater and chlorides?
A: Corrosion resistant; titanium alloy forms a stable passivation film, ensuring reliable long-term performance.
Q: Has it undergone non-destructive testing?
A: Yes, ultrasonic testing is routinely performed, and radiographic testing can be done upon request.
Q: Does it support customization?
A: Yes, dimensions, pressure ratings, and sealing surfaces can be produced according to drawings.
Q: Does it provide testing documents?
A: Material certificates and factory test reports are provided, and third-party verification is supported.
Q: Is the delivery time stable?
A: Delivery time is stable for standard specifications; customized specifications are confirmed according to the process cycle.
Q: How is it packaged and transported?
A: A: Sealing surface protection, individual anti-collision packaging, reinforced outer box for transportation.
