Our carbon steel flanges are manufactured in compliance with ASME B16.5, ASTM A105, ASTM A350 LF2, and API standards, making them fully compatible with Kuwait’s dominant ANSI/ASME framework. We supply flanges in pressure classes ranging from 150# to 2500# and sizes from ½” to 60″, catering to both standard procurement requirements and custom project specifications across Kuwait’s industrial heartlands—Kuwait City, Ahmadi, Shuaiba, Shuwaikh, Al Wafra, Jahra, and Mina Al-Ahmadi.
Our product range covers all primary carbon steel flange types: Weld Neck, Slip On, Blind, Socket Weld, Threaded, Lap Joint, and Spectacle Blind flanges. Each unit undergoes dimensional inspection, mechanical testing, and non-destructive testing (NDT) before dispatch. We ship via Shuwaikh Port and Shuaiba Port with sea freight transit times of 18–25 days and air freight options for urgent requirements.
Whether you are a contractor working on the Al-Zour Refinery integration complex, an EPC firm engaged in KOC's upstream expansion, or a procurement team sourcing flanges for a power generation or desalination facility, Werner Flanges delivers verified quality, full material documentation, and competitive lead times.

Industries and Applications We Supply
| Industry | Applications |

Oil & Gas Industry |
Kuwait’s oil and gas sector is the foundation of the country’s economy, with Kuwait Petroleum Corporation managing a fully integrated supply chain through its “K Companies.” Carbon steel flanges are critical piping components across every segment of this chain. Upstream — Kuwait Oil Company (KOC): KOC operates Kuwait’s onshore and offshore oil fields, including the Greater Burgan Field (the second-largest oil field in the world), Raudhatain, Sabriya, and Minagish fields. Carbon steel flanges in Class 300# to 900# are used extensively in wellhead assemblies, production manifolds, test separators, gathering system headers, and gas compression packages. KOC’s 2024–2029 upstream investment program—targeting production capacity increases from 2.9 to 3.2 million barrels per day—includes drilling of 44 new rigs and expanded oil processing facility construction, generating significant demand for flanged piping components. Midstream — KOTC & Pipeline Systems: Kuwait Oil Tanker Company and the national pipeline network connecting oil fields to refineries and export terminals at Mina Al-Ahmadi use carbon steel flanges in Class 150# to 600# for crude oil transmission, product transfer, and LPG distribution lines. Downstream — KNPC Refineries: Kuwait National Petroleum Company operates the Mina Al-Ahmadi Refinery (466,000 bbl/day), Mina Abdullah Refinery (270,000 bbl/day—recently upgraded under the Clean Fuels Project), and the newly commissioned Al-Zour Refinery (615,000 bbl/day). All three refineries use carbon steel flanges extensively in crude distillation units, vacuum units, coker units, hydrotreaters, and utility systems. ASTM A105 Class 300# and 600# flanges predominate in process service, while A350 LF2 flanges are specified for low-temperature overhead systems.. |

Frequently Asked Questions (FAQs)
-
Q1: Are your carbon steel flanges compatible with KOC and KNPC material specifications?
- Yes. Werner Flanges’ ASTM A105 and A350 LF2 carbon steel flanges are manufactured to the material and dimensional standards referenced in KOC and KNPC standard purchase specifications. We can provide material qualification documentation, including mill test certificates and third-party inspection reports, to support vendor qualification submissions.
-
Q2: What is the typical delivery time for carbon steel flanges to Kuwait?
- Sea freight from our manufacturing facility to Shuwaikh or Shuaiba Port is 18–25 days. For in-stock items (common sizes in Class 150# to 600#, NPS ½” to 24″), orders can be dispatched within 3–5 working days of order confirmation. Air freight is available for urgent small-quantity requirements, with a transit time of 3–5 days to Kuwait International Airport.
-
Q3: Can you supply NACE MR0175 compliant flanges for Kuwait’s sour crude service?
- Yes. For KOC upstream applications in H₂S-containing environments, we supply ASTM A105N flanges with hardness controlled to ≤22 HRC (≤237 HBN) in compliance with NACE MR0175 / ISO 15156. NACE compliance declarations are included in the documentation package. Sulfide stress cracking (SSC) region designation (Region 0, 1, 2, or 3) can be specified at time of order.
-
Q4: Do you offer third-party inspection before shipment?
- Yes. We routinely facilitate pre-shipment inspection by TÜV Rheinland, DNV GL, Bureau Veritas, Lloyd’s Register, SGS, and other approved inspection bodies. Inspection can be arranged to align with the inspection and test plan (ITP) requirements of your project, including witness and hold points as specified.
-
Q5: Can you supply large-diameter flanges (above NPS 24″) for Kuwait pipeline projects?
- Yes. Werner Flanges manufactures and supplies carbon steel flanges in NPS 26″ to 60″ to ASME B16.47 Series A (MSS SP-44) and Series B (API 605). These large-diameter flanges are used in Kuwait’s crude oil trunk lines, produced water injection systems, and major refinery piping headers. Extended lead times of 6–10 weeks apply for sizes above NPS 36″.
-
Q6: Can you provide carbon steel flanges with dual certification (e.g., A105/A350 LF2)?
- Yes. Dual-certified flanges meeting both ASTM A105 and ASTM A350 LF2 chemical and mechanical requirements are available. These are useful for projects where the minimum design metal temperature (MDMT) requirement may shift during detailed engineering, avoiding the need for re-procurement. Dual certification is noted on the MTC and flange marking.
