Product Detail
Product Introduction
Titanium Grade 5 Flanges is supplied for corrosion-resistant fabrication and precision manufacturing. The final purchase definition must identify the exact material designation, governing specification and revision, dimensions, condition, tolerances, tests and documentation; trade-name or cross-standard equivalence is not assumed.
What must be checked before specifying a Grade 5 titanium flange?
Selection answer: Grade 5 Ti-6Al-4V is selected for high specific strength or mechanically demanding flange and connection designs; it should not be described as a universal corrosion upgrade over commercially pure titanium.
Selection boundary: Material strength alone does not establish a piping pressure rating. Confirm the forging condition, flange geometry, mating components, fastener loads, temperature, corrosion data and the governing design code.
RFQ data to confirm: State NPS or drawing dimensions, class, type, facing, bore, Grade 5 condition, design loads or pressure, temperature, service medium, inspection, quantity and required certificates.

Certificates & Inspection Records

Services We Can Provide
Product Packaging
Machined faces, bores and bevels are protected with covers or wrapping. Flanges are separated by grade, size and heat, then secured in reinforced export cases with traceability labels. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
