Premium Quality Flanges for UAE

Leading Supplier of Premium Quality Flanges for UAE’s Oil, Gas & Petrochemical Industries

Werner Flanges stands as a trusted flanges supplier in UAE with over two decades of manufacturing excellence, serving the nation's dynamic industrial landscape. As the United Arab Emirates continues to expand its position as a global energy hub, we provide comprehensive flange solutions to support critical infrastructure across Dubai, Abu Dhabi, Sharjah, Ajman, and the Northern Emirates.

Our manufacturing facility produces a complete range of industrial flanges including ANSI B16.5 flanges, stainless steel flanges, carbon steel flanges, weld neck flanges, and slip on flanges engineered to meet the demanding requirements of UAE’s oil and gas sector, petrochemical complexes, and construction megaprojects. We supply premium-grade flanges manufactured from Carbon Steel (ASTM A105), Stainless Steel (304, 316, 321), Alloy Steel (F11, F22, F91), and Duplex materials (F51, F53, F55).

Every flange we export to UAE complies with international standards including ASME B16.5, ASME B16.47, DIN 2633, EN 1092-1, and BS 4504, ensuring seamless integration with existing pipeline systems operated by ADNOC, ENOC, Dubai Petroleum, and leading EPC contractors. Our commitment to quality, competitive pricing, and reliable delivery timelines has made us a preferred partner for industrial projects across the Emirates.

Weld neck flanges are the most structurally robust type of pipe flange, featuring a long tapered hub that gradually transitions from the flange thickness to the pipe wall thickness. This unique design provides exceptional stress distribution and is specifically engineered for high-pressure, high-temperature applications where cyclic loading and thermal expansion are critical concerns. The tapered hub design of weld neck flanges creates a smooth bore that matches the inside diameter of the connecting pipe, minimizing turbulence and pressure drop in fluid flow systems.

Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	The United Arab Emirates ranks among the world’s top petroleum producers, and Werner Flanges proudly supports this critical sector. We supply flanges to ADNOC (Abu Dhabi National Oil Company) and its subsidiaries including ADNOC Onshore, ADNOC Offshore, and ADNOC Gas Processing. Our products are integral to operations at the Ruwais Refinery (one of the world’s largest single-site refineries), offshore platforms in the Upper Zakum and Umm Shaif fields, and gas processing facilities in Habshan and Asab. We also serve ENOC (Emirates National Oil Company) facilities in Dubai, including the Jebel Ali refinery and fuel distribution networks. Our flanges meet the demanding specifications for sour gas service, high H2S environments, and extreme temperature applications common in UAE’s oil and gas operations. From wellhead connections to pipeline gathering systems, from crude processing units to export terminals, our NACE MR0175 compliant flanges ensure operational reliability.
Petrochemical & Chemical Processing	UAE’s petrochemical sector, anchored by facilities in Ruwais Industrial City and Jebel Ali, relies on our corrosion-resistant flanges. Borouge (a joint venture between ADNOC and Borealis) operates one of the world’s largest integrated polyolefin complexes in Ruwais, where our stainless steel and alloy steel flanges handle aggressive chemicals, high temperatures, and pressurized reactor systems. The Taweelah Petrochemical Complex and chemical manufacturing units in Dubai Industrial City use our specialized flanges for ammonia production, fertilizer plants, and industrial gas applications. Our duplex and super duplex stainless steel flanges provide exceptional resistance to chloride stress corrosion cracking, critical for processes involving chlorine, caustic solutions, and acidic environments.
Power Generation	UAE’s ambitious energy diversification includes massive investments in power generation infrastructure. We supply flanges to the Barakah Nuclear Power Plant (UAE’s first nuclear facility), where our ASME SA-182 certified flanges meet stringent nuclear safety standards. Solar power projects including the Mohammed bin Rashid Al Maktoum Solar Park utilize our flanges in heat transfer systems and cooling circuits. Gas-fired power plants operated by Emirates Water and Electricity Company (EWEC) in Abu Dhabi and Dubai Electricity & Water Authority (DEWA) depend on our high-temperature alloy steel flanges for turbine connections, steam systems, and combined-cycle applications. Our products withstand operating temperatures exceeding 550°C while maintaining pressure integrity.
Water Treatment	Given UAE’s arid climate, desalination represents a critical industry. We provide specialized flanges to the Taweelah Reverse Osmosis Desalination Plant (world’s largest RO facility), Jebel Ali Desalination Plant, and numerous DEWA facilities. Our super duplex stainless steel flanges (F53, F55) resist seawater corrosion, while our titanium and nickel alloy options handle the most aggressive brine environments.
