Leading ANSI B16.5 Flanges Manufacturer & Exporter to
Kuwait's Oil, Gas & Petrochemical Industries
Kuwait's hydrocarbon sector is one of the most capital-intensive and technically demanding industrial environments in the world. With the Kuwait Petroleum Corporation (KPC) driving a $30 billion, five-year upstream investment program and the fully operational Al-Zour Refinery now processing 615,000 barrels per day, the demand for precision-engineered, standards-compliant pipeline components has never been higher. Werner Flanges is proud to be a trusted manufacturing and supply partner for ANSI B16.5 flanges across Kuwait's upstream, midstream, and downstream sectors.
With over two decades of forging and machining expertise, Werner Flanges manufactures a complete range of ANSI/ASME B16.5 flanges in carbon steel, stainless steel, alloy steel, duplex, and super duplex materials — all produced to the tightest dimensional and mechanical tolerances. We serve major contractors, engineering firms, and end-user operators across Kuwait City, Al Ahmadi, Shuaiba Industrial Area, Mina Al-Zour, and Jahra.
Our product range covers all seven standard flange types — Weld Neck, Slip On, Blind, Socket Weld, Threaded, Lap Joint, and Orifice — in pressure classes from 150# through 2500# and sizes from ½” to 60″. Every flange manufactured at our facility is produced in compliance with ASME B16.5, ASTM material standards, and API specifications, and is supported by a full documentation package including material test certificates, dimensional inspection reports, and third-party inspection clearances.
Whether your project involves KOC drilling operations, a KNPC refinery expansion, KIPIC petrochemical integration, or a private-sector EPC contract at the Shuaiba Industrial Estate, Werner Flanges delivers consistent quality, competitive pricing, and reliable sea freight delivery to Shuwaikh Port and Shuaiba Port — typically within 18–25 days.

Industries and Applications We Supply
| Industry | Applications |

Oil & Gas Industry |
Kuwait holds approximately 7% of global proven oil reserves and the KPC family of companies — Kuwait Oil Company (KOC), Kuwait National Petroleum Company (KNPC), Petrochemical Industries Company (PIC), and Kuwait Integrated Petroleum Industries Company (KIPIC) — drives an enormous demand for high-specification pipeline components. Upstream (KOC): Werner Flanges’ ANSI B16.5 weld neck and blind flanges in ASTM A105 and F316/316L are used extensively across KOC’s producing fields — Burgan (one of the world’s largest oil fields), Raudhatain, Sabriya, and the Neutral Zone Wafra and Khafji fields. Class 900# and 1500# flanges serve high-pressure wellheads and gathering manifolds. Blind flanges are critical during well testing and pressure isolation. Midstream (KOTC): The Kuwait Oil Tanker Company operates crude oil pipelines connecting producing fields to export terminals. Werner Flanges supplies class 300# and 600# carbon steel flanges for crude transfer lines and pump stations along these corridors. Downstream (KNPC/KIPIC): The Al-Zour Refinery complex — the world’s largest single-phase construction project — and the Mina Al-Ahmadi and Mina Abdulla refineries represent Kuwait’s massive downstream footprint. Werner Flanges supplies alloy steel F11 and F22 flanges for high-temperature hydrocracker and reformer units, stainless F316L flanges for corrosive process streams, and duplex F51 flanges for sour service applications across these facilities. |

Water Treatment |
Kuwait is one of the world’s highest per-capita consumers of desalinated water, with multiple multi-stage flash (MSF) and reverse osmosis (RO) desalination plants operating at Shuwaikh, Shuaiba, Az-Zour, and Doha. Duplex F51 and super duplex F53 flanges are critical in seawater intake and brine discharge systems, where chloride-induced corrosion would rapidly attack standard carbon or stainless steel. Carbon steel A105 flanges serve freshwater distribution networks. Werner Flanges is a proven supplier for both MSF and RO plant construction and maintenance projects. |
