Leading Flange Manufacturer & Exporter Serving Turkey
Werner Flanges is a globally recognized manufacturer and exporter of industrial flanges, proudly serving Turkey's rapidly growing oil and gas, petrochemical, construction, shipbuilding, and energy sectors. From the bustling port of Mersin on the Mediterranean coast to the industrial heartland of Ankara and the commercial powerhouse of Istanbul, Werner Flanges delivers precision-engineered flanges that meet the rigorous demands of Turkish industry — on time, to specification, and at competitive prices.
Turkey stands at a strategic crossroads between Europe, Asia, and the Middle East, making it one of the region’s most dynamic industrial markets. The country’s ambitious infrastructure expansion under Vision 2053, growing energy import and transit infrastructure, and the rapid development of its refining and petrochemical base have generated surging demand for high-quality piping components including flanges, fittings, and valves. Werner Flanges is positioned as a trusted supply partner for Turkish engineering firms, EPC contractors, petrochemical operators, and maintenance teams.
We manufacture flanges in carbon steel, stainless steel, alloy steel, and duplex grades — conforming to ASME B16.5, ASME B16.47, EN 1092-1, DIN 2631–2638, and GOST standards — covering pressure classes from PN6 to PN420 (DIN/EN) and Class 150 to Class 2500 (ASME). Our products ship to Istanbul, Izmir, Ankara, Mersin, Bursa, Aliaga, Kocaeli, and all major Turkish industrial centers within 18–25 days via sea freight, with express air freight options available for urgent requirements.
As a direct manufacturer with no intermediary markup, Werner Flanges offers Turkish buyers a compelling combination of quality, price competitiveness, and documentation excellence — including CE-marked products under PED 2014/68/EU where required, full EN 10204 3.1 material certifications, and third-party inspection by TÜV, Bureau Veritas, or Lloyd's Register.

Industries and Applications We Supply
| Industry | Applications in Turkey |
|---|---|
Oil, Gas & Petrochemical Sector |
Turkey serves as a key natural gas transit country, handling flows from Russia, Azerbaijan, and Central Asia via TANAP, TAP, and TurkStream. Domestic oil exploration occurs in the Southeast Anatolian Basin (Batman, Diyarbakir). Pipeline & Transmission: Carbon steel flanges (Class 300#–900#) are used in trunk lines, compressor stations, and metering facilities for high-pressure gas transport. Refineries & Petrochemical Plants: TUPRAS refineries (Izmit, Izmir, Kirikkale, Batman) and Petkim Petrochemical Complex (Aliaga, Izmir) use extensive ASTM A105 and stainless steel flanges for crude distillation, catalytic cracking, and chemical processing lines. |
Energy & Power Generation |
Turkey’s installed capacity exceeds 100 GW, including thermal, hydro, wind, solar, and nuclear (Akkuyu under construction). Gas-Fired Power Plants: Carbon steel flanges are used in steam systems, feedwater, and fuel gas lines for combined-cycle power plants, with supply to Ankara, Istanbul, and coastal industrial zones. |
Shipbuilding & Marine Industry |
Turkey ranks among the world’s top 10 shipbuilding nations. Major shipyards are located in Tuzla (Istanbul), Yalova, Eregli, and Altinova. Marine Applications: Marine piping systems require stainless steel (ASTM A182 F304/F316), duplex, and carbon steel flanges compliant with Lloyd’s Register, Bureau Veritas, and DNV. Used in cargo ships, tankers, ferries, and naval vessels. |
Water Treatment & Infrastructure |
Urban water infrastructure, desalination projects on Mediterranean and Aegean coasts, and large irrigation systems under GAP (Southeastern Anatolia Project) use Class 150# and 300# carbon steel flanges. Applications: Water supply networks in Istanbul, industrial water systems in Ankara, and coastal desalination facilities rely on reliable flanged connections suitable for potable and industrial water service. |
