Titanium Flange

Key Advantages

Corrosion-ready grades: Gr2 (CP), Gr7 (Pd-alloy, chlorine service), Gr12 (Ti-0.3Mo-0.8Ni, galvanic mitigation), Gr5 (high-strength, non-welded uses).
Standards coverage: ASME B16.5/B16.47, MSS SP-44, EN 1092-1, JIS B2220—easy interchange with existing pipework.
Tight sealing faces: stock/raised ring, RTJ, or tongue-and-groove; controlled Ra for reliable gasket seating.
Traceable quality: heat/lot tracking with MTC EN 10204 3.1; PMI/XRF on request.
Flexible supply: forged or machined from plate; custom drilling patterns, reducer/expanding designs, small-batch prototypes available.

Primary Applications

Chemical & desalination: chlorine/halide media, seawater service, scrubbers, heat-exchangers.
Oil & gas / offshore: lightweight, corrosion-resistant tie-ins and manifolds.
Power & nuclear balance-of-plant: low neutron absorption (CP grades), corrosion-critical piping.
Pharma & ultrapure systems: low contamination risk, clean surface finishes.

Testing (typical)

PMI / XRF for grade verification; dye-penetrant (PT) on sealing faces.
Dimensional check to ASME/EN/JIS drawings; bolt-hole pattern & thickness.
Surface roughness (e.g., Ra 3.2–6.3 μm for RF) with reports on request.
Hydrostatic / leak test when supplied as assembled spools (on request).
Documentation: MTC 3.1, RoHS/REACH statements.

Packaging & Delivery

Packaging: PE wrap + edge protectors; flange faces with plastic covers; export plywood cases.
Labeling: grade, standard, size/class, heat/lot, PO; gasket face type & Ra where applicable.
Shipping: global courier/sea freight; lead times aligned to your schedule.

Send your specifications (grade, size, quantity) — quotation and lead time within 12 hours. Trial orders with flexible MOQ are supported for evaluation and qualification. All materials are supplied with EN 10204 3.1 MTC and full inspection documentation for export compliance.

Product Description

Premium titanium flanges for corrosive and weight-sensitive piping systems. LuminaTitan forges and machines Gr2/Gr7/Gr12 (and selected Gr5) flanges to ASME/EN/JIS standards under controlled processes and in-house inspection. Parts are supplied with traceable heat/lot IDs and optional surface-finish certificates to ensure reliable sealing and long service life.
