6. The Production Porcess of Titanium Slip On Flanges

Material Selection:

Titanium Alloy: The process begins with selecting the appropriate titanium alloy based on the application requirements. Common alloys used include Grade 2 (commercially pure titanium), Grade 5 (Ti-6Al-4V), and Grade 7 (Ti-0.15Pd) depending on factors such as strength, corrosion resistance, and temperature requirements.

Cutting and Forming:

Raw Material Preparation: Titanium billets or bars are cut into appropriate lengths based on the required flange dimensions.

Forging or Rolling: The titanium material is heated to a suitable forging temperature and then shaped using forging or rolling techniques to achieve the desired shape and size of the slip-on flange blank.

Machining:

Turning and Milling: The forged or rolled titanium blanks undergo machining operations. This includes turning to create the outer diameter (OD) and facing the flange ends to achieve the required surface finish (e.g., raised face, flat face, ring type joint).

Drilling: Holes are drilled for bolt and pipe alignment according to ASME B16.5 or customer specifications.

Welding Preparation:

Beveling: The flange ends are beveled to prepare for welding. This step ensures proper weld penetration and strength during assembly.

Welding:

Welding Process: Titanium slip-on flanges are typically welded using TIG (Tungsten Inert Gas) welding or other suitable methods. Care is taken to maintain an inert atmosphere (usually argon) to prevent contamination and ensure strong, corrosion-resistant welds.

Weld Inspection: Welds undergo non-destructive testing (NDT) methods such as dye penetrant inspection or ultrasonic testing to verify weld integrity and detect any defects.

Heat Treatment (if required):

Depending on the titanium alloy and specific requirements, heat treatment may be performed to relieve stress or enhance material properties. This step ensures the flange maintains its mechanical properties and dimensional stability.

Final Inspection and Testing:

Dimensional Inspection: Each flange undergoes dimensional checks to ensure it meets the specified tolerances and dimensions as per ASME B16.5 or customer requirements.

Visual and Surface Inspection: The flange surfaces are visually inspected for any imperfections or defects that could affect performance.

Pressure Testing: Hydrostatic or pneumatic pressure testing may be conducted to verify the flange’s leak-tightness and pressure resistance.

Surface Treatment and Finishing:

Surface Coating: Depending on the application, surface treatments such as passivation or anodizing may be applied to enhance corrosion resistance or improve aesthetics.

Marking and Identification: Each flange is marked with essential information such as material grade, size, pressure class, and manufacturer identification.

Packaging and Shipping:

Once all inspections and tests are completed satisfactorily, the titanium slip-on flanges are packaged securely to prevent damage during transport and storage. They are then shipped to the customer or to distribution centers.

7. Test Certificates of Titanium Flanges

EN 10204/3.1B Certificate:

This is a standard certificate that confirms compliance with the material specification and provides chemical composition and mechanical properties of the titanium alloy used in manufacturing the flanges. It is issued by the manufacturer and verifies that the material meets the required standards.

Raw Materials Certificate:

This certificate provides details about the raw materials used in the production of the titanium flanges. It includes information such as the origin of the raw materials, their composition, and any applicable material testing results. This ensures traceability and quality control from the initial material procurement stage.

100% Ultrasonic Flaw Detection:

Ultrasonic testing (UT) is a non-destructive testing method used to detect internal and surface defects in the titanium flanges. A 100% UT coverage means that all flanges undergo thorough testing to ensure there are no defects that could compromise their structural integrity or performance.

Hydrostatic Test:

This test involves pressurizing the titanium flange with water or another liquid to a predetermined pressure level. It assesses the flange's ability to withstand pressure without leakage or deformation, ensuring it meets the specified pressure ratings and safety requirements.

Third Party Inspection Report:

This report is conducted by an independent third-party inspection agency or authority. It provides an unbiased assessment of the titanium flanges' quality, confirming compliance with applicable standards, specifications, and customer requirements. It adds credibility to the manufacturer's quality assurance processes.
