Direct supply from Baoji Titanium Valley. Fully traceable commercial pure and alloy titanium engineered to ASTM B348, ASTM B381, ASTM B265, and ASME B16.5 international pressure specifications.
A technical evaluation of commercially pure Grade 2 (UNS R50400) and Palladium-stabilized Grade 7 (UNS R52400) plate flanges engineered to mitigate pitting, crevice corrosion, and galvanic degradation in Cypriot offshore and coastal industrial applications.
The metallurgical stability of ASME B16.5 Grade 2 titanium plate flanges stems from the instantaneous formation of an adherent, chemically unreactive, and self-healing titanium dioxide (TiO2) rutile/anatase oxide film upon exposure to oxygen or moisture. In the hypersaline and elevated ambient temperatures of the Levantine Basin, where conventional duplex and super duplex stainless steels suffer localized crevice pitting, titanium's oxide film remains thermodynamically stable across pH ranges from 2 to 12.
Machined directly from fine-grained ASTM B265 Grade 2 rolled plates or ASTM B381 F2 forgings, our plate flanges (Type 01 / Plate Blank) adhere rigorously to ASME B16.5 dimensional tolerances. Facing options incorporate smooth machine finishes (Ra 3.2 to 6.3 μm) or serrated concentric/spiral grooves (125 to 250 AARH) ensuring non-slip gasket compression against PTFE, spiral-wound, or expanded fluoropolymer gaskets under sustained cyclic line vibration.
For hypersaline brine handling in reverse osmosis plants or high-temperature acidic blowdown lines where crevice conditions drop below pH 2, Jovzi supplies ASME B16.5 flanges in Grade 7 (Ti-0.15Pd). The palladium micro-alloying acts as an efficient cathodic depolarizer, raising the open-circuit corrosion potential into the passive zone of titanium and eliminating crevice degradation even under anaerobic gasket interfaces.
As Cyprus cements its role as an East Mediterranean energy hub and regional maritime center, the demand for corrosion-immune titanium flanged connections has transitioned from a specialized luxury to an engineering necessity. Jovzi Titanium supplies tailored ASME B16.5 Grade 2 and Grade 7 plate flanges engineered to overcome the high salinity and elevated sea surface temperatures characteristic of the Mediterranean basin.
Comprehensive physical, chemical, and dimensional compliance parameters for Grade 2 and Grade 7 commercial titanium supply chains.

Strategic structural shifts shaping how Cypriot procurement authorities, EPC contractors, and marine operators acquire high-performance materials.
With Mediterranean emissions control areas (Med ECA) tightening sulfur oxide restrictions, shipping companies operating through Limassol port are executing retrofits with marine exhaust gas cleaning systems. Corrosive sulfuric acid condensation in washwater return manifolds mandates Grade 2 and Grade 7 plate flanges to avoid catastrophic mid-voyage piping failure.
Historically, EPC tenders in Cyprus favored copper-nickel (CuNi 90/10) or super austenitic stainless steels due to initial procurement costs. Current infrastructure projects now evaluate 30-year Life-Cycle Costing. Titanium's total resistance to corrosion eliminates maintenance downtime, replacement piping runs, and biocidal chemical dosing, proving dramatically cheaper across a facility's design life.
Cypriot procurement directors are increasingly bypassing third-party European distribution markups by establishing direct factory agreements with specialized manufacturers in Baoji, China. Utilizing FOB Qingdao or direct CIF Limassol logistics with comprehensive EN 10204 3.1 mill testing reduces supply lead times and ensures authentic chemical heat-number pedigree.
Operating since 2006 in Baoji, Shaanxi — the core of China's Titanium Valley — Jovzi Titanium Industry Co., Ltd. integrates sponge raw materials into high-precision ASME, DIN, and ASTM industrial flow equipment.
All batches undergo independent chemical, tensile, and metallographic testing authorized by the BaoTi Test Center, delivering verifiable EN 10204 3.1 MTC certificates with full heat traceability.
Located at No. 3 Gaoya Industrial Zone, our facility integrates 1,000–3,000 m² of precision CNC machining centers, forging presses, and automated thread rolling equipment operated by veteran engineers.
From raw titanium sponge melt verification to final coordinate measuring machine (CMM) dimensional checks, our quality system ensures zero flange face deflection and tight bolt hole concentricity.
Offering CIF Limassol, FOB Qingdao, or express DHL/FedEx delivery. Seaworthy fumigated wooden crates with moisture-barrier vacuum packing eliminate mechanical damage during maritime transit.
Technical, commercial, and operational considerations for sourcing titanium ASME B16.5 plate flanges in Cyprus.
Titanium is the more noble metal in the galvanic series. When connected directly to carbon steel, stainless steel, or copper-nickel without insulation, the adjacent piping material will experience accelerated galvanic oxidation. For Cypriot marine installations, we recommend using dielectric insulation gasket kits (such as G10/Mylar sleeves, washers, and PTFE seals) or pairing titanium flanges directly with ASTM B363 titanium stub ends and lap joint backing flanges.
Our standard ASME B16.5 Grade 2 plate and slip-on flanges are finished with a serrated concentric or spiral groove finish between 125 μin and 250 μin AARH (Ra 3.2 to 6.3 μm) using high-precision CNC tool nose geometry. For vacuum, elastomer, or specialized non-metallic flat gaskets in chemical dosing lines, we supply smooth machine-turned finishes with Ra ≤ 1.6 μm upon request.
Yes. While ASME B16.5 (Class 150/Class 300) is standard for oil, gas, and desalination facilities, many European EPCs in Cyprus specify EN 1092-1 Type 01 (Plate) or Type 11 (Weld Neck) flanges in PN10, PN16, PN25, and PN40. Our engineering workshop machines custom plate flanges from 1/2" (DN15) up to 48" (DN1200) according to CAD/STEP files or buyer drawings.
Every shipment is accompanied by complete inspection dossiers, including the EN 10204 3.1 Mill Test Certificate indicating mechanical properties (Tensile, Yield, Elongation) and chemical composition per heat number. Furthermore, raw sponge records, ultrasonic testing (UT) reports per AMS 2631 / ASTM E114, dimensional inspection certificates, and Certificate of Origin (COO) are provided.
Solid ASME B16.5 titanium plate flanges offer superior rigidity, eliminate the risk of atmospheric crevice corrosion beneath loose backing rings, and simplify alignment during tight module construction on offshore skids. However, for cost optimization on larger diameters (> 6" Class 150), Jovzi also manufactures ASTM B363 Grade 2 stub ends paired with coated steel lap joint flanges.
For standard ASME B16.5 Class 150/300 Grade 2 flanges, our minimum order quantity is just 1 piece or 1 kg from stock. Custom machined forgings or Grade 7 alloys require an MOQ based on raw forging billet sizes. Standard fabrication lead times range from 10 to 20 working days, with sea freight delivery to Limassol Port taking approximately 22 to 28 days.
Whether you require standard Grade 2 Class 150 plate flanges, Grade 7 palladium alloys for high-salinity brine lines, or custom CNC flanges produced to tight technical drawings, our metallurgical team in Baoji delivers verifiable quality, ISO 9001 assurance, and direct factory pricing.
