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.

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.
