Titanium Pipe Flange Factory & Supplier Serving Poznań

Passivation & Oxide Layer Integrity

The exceptional corrosion immunity of titanium pipe flanges originates from the instantaneous formation of a continuous, thermodynamically stable, and tenacious titanium dioxide (TiO₂) film. Even under high shear fluid dynamics, damaged oxide layers spontaneously re-passivate within milliseconds in the presence of trace oxygen or moisture.

• Pitting and crevice immunity in chlorine brines up to 80°C
• Zero localized stress corrosion cracking in high-chloride waters
• Completely inert to nitric acid, organic acids, and wet chlorine

Grain Refinement via Closed-Die Forging

Unlike cut-plate rings that expose open end-grain structures prone to edge flaking and intergranular weaknesses, Jovzi titanium flanges are hot-forged strictly in accordance with ASTM B381. Die-forging directs metallurgical flow lines along the contour of the flange neck, Hub, and gasket sealing face, ensuring maximum mechanical stability.

• Conforms to ASME B16.5 and EN 1092-1 Type 11 weld necks
• Eliminates micro-voids, dendritic segregations, and internal porosity
• Hydrostatic testing integrity up to Class 600 / PN100 ratings

Thermal Dynamics & Weight Reduction

Operating at a density of 4.51 g/cm³, titanium offers a 45% weight saving over stainless steel (1.4404 / 316L) while presenting equivalent or superior tensile yield ratings. Its thermal expansion coefficient (8.6 × 10⁻⁶/K) closely matches that of borosilicate equipment and ceramic liners, preventing cyclic flange face thermal fatigue.

• Reduces static support loads on elevated pipeline runs
• Exceptional vibration damping in high-flow turbine exhaust runs
• Extended gasket retention under wide cyclic temperature shifts

Chemical Synthesis & Fertilizer Manufacturing

Facilities located throughout the Greater Poland corridor, including Luboń and surrounding chemical centers, handle acidic compounds, phosphorus derivatives, and chlor-alkali solutions. Jovzi Grade 2 (UNS R50400) and Grade 7 (Ti-0.15Pd, UNS R52400) welding neck and blind flanges prevent severe crevice degradation in hot chloride-rich environments.

Where high operating temperatures cause localized breakdown of Hastelloy or 904L alloys, titanium Grade 7 palladium additions stabilize the corrosion potential, ensuring leak-tight joints across reactors and heat-exchanger tie-ins.

Combined Heat & Power (CHP) & Waste-to-Energy

Modern district heating systems, such as Poznań's Elektrociepłownia Karolin and regional municipal thermal treatment facilities, implement advanced Flue Gas Desulfurization (FGD) scrubbers. Flue condensates present severe sulfuric and hydrochloric acid concentrations that rapidly destroy standard carbon and austenitic steels.

We supply EN 1092-1 Type 01 flat plate flanges, Type 02 loose flanges with ASTM B363 titanium stub ends, and Grade 12 (Ti-0.3Mo-0.8Ni) blind flanges engineered specifically to withstand wet acidic flue gas zones without embrittlement.

Automotive Powertrain & Custom Motorsport Fabrication

Poznań is a premier center of Poland's automotive sector, housing high-volume vehicle manufacturing plants (such as Volkswagen Poznań) alongside specialized racing engineering workshops. These entities demand extreme thermal resilience combined with mass reduction for forced-induction racing prototypes.

Our Grade 5 (Ti-6Al-4V) manifold studs, Grade 1/Grade 2 pie cuts, and 2-bolt / V-band clamp flanges offer custom exhaust fabricators lightweight connections capable of enduring continuous 700°C exhaust gas pulses without cracking.

Biopharma, Starch Processing & Food Technology

Poznań's rich agricultural processing belt and expanding biotechnology parks rely on ultra-hygienic processing equipment that prevents heavy metal ion contamination. In vinegar distillation, potato starch processing, and pharmaceutical sterile synthesis, product purity is governed by sanitary standards.

Jovzi supplies mirror-polished ASME B16.5 Class 150 titanium slip-on flanges and smooth-bore seamless titanium reducers that prevent microbial adhesion and resist harsh SIP/CIP (Sterilization/Clean-in-Place) caustic wash cycles.

The Wielkopolska Hydrogen Valley Initiative

As Greater Poland leads industrial decarbonization through the Wielkopolska Hydrogen Valley (Wielkopolska Dolina Wodorowa), PEM (Proton Exchange Membrane) water electrolyzers are being deployed at pilot and commercial scales. Titanium is one of the few structural materials capable of handling the extreme anodic overpotentials and acidic membrane environments without releasing catastrophic poisoning ions.

Our forged titanium blind flanges, spectacle blinds, and bipolar plate blanks are heavily integrated into green hydrogen balance-of-plant manifolds across regional installations.

Strict Compliance with EU Industrial Emissions Directive

With stricter compliance requirements under the EU Industrial Emissions Directive (IED 2.0), chemical and energy production plants in Poznań can no longer tolerate fugitive emissions or unscheduled pipeline leaks caused by pitting failure of 316L or Duplex 2205 flanges. Plant operators are systematically shifting from recurring maintenance cycles to high-integrity, zero-corrosion titanium systems.

The initial capital cost of Jovzi titanium flanges is rapidly amortized by eliminating routine gasket replacements, chemical shutdown flushes, and premature pipe segment rebuilds.

Direct Supply Chains Bypassing Middle-Tier Markups

Historically, Polish maintenance, repair, and overhaul (MRO) contractors procured titanium through secondary European stockholders, incurring steep distributor margins and vague material traceability. Poznań engineering teams now establish direct mill-to-factory supply relationships with Jovzi Titanium in Baoji, China.

This direct procurement pathway delivers complete EN 10204 3.1 mill certification, verified BaoTi test data, custom machining tolerances (ISO 2768-m), and landed cost reductions of up to 25–40%.

ASME B16.5 Dimensions

We produce nominal pipe sizes (NPS) from ½" up to 48" across pressure classes 150, 300, 600, 900, and 1500. Sealing surfaces include Raised Face (RF) serrated to Ra 3.2–6.3 µm, Flat Face (FF), and Ring Type Joint (RTJ) for ultra-high pressure duties.

EN 1092-1 European Norms

Fully compliant with Polish and European pipeline installations: Type 01 (plate), Type 02 (loose with stub end), Type 05 (blind), Type 11 (welding neck), and Type 12 (hubbed slip-on) across PN6, PN10, PN16, PN25, PN40, PN63, and PN100 ratings.

Custom Machining to Drawing

Equipped with 3-axis, 4-axis, and 5-axis CNC machining centers, Jovzi fabricates specialty non-standard flange connections, spectacle blinds per ASME B16.48, and custom autoclave lids directly from customer-supplied CAD (STEP, DWG, DXF) files.

Sponge-to-Forging Traceability

We melt zero substandard scrap. All ingots originate from high-purity aerospace-grade titanium sponge vacuum-arc remelted (VAR) twice or three times, ensuring unmatched chemical homogeneity.
