Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	Kenya’s petroleum sector is one of the most significant consumers of industrial flanges in the country. The Kenya Pipeline Company (KPC) operates a 2,048 km refined petroleum products pipeline network from Mombasa to Kisumu, Eldoret, Nairobi, and beyond — all of which requires certified carbon steel flanges at pump stations, storage facilities, and metering points.Emerging upstream oil activity in the South Lokichar Basin (Turkana County), driven by Tullow Oil and its partners, has generated direct demand for high-pressure weld neck and blind flanges rated for wellhead and flowline service. Werner Flanges supports exploration and production (E&P) contractors, EPCs, and procurement agents involved in Kenya’s upstream sector.
Construction, Infrastructure & LAPSSET	The LAPSSET Corridor Development Authority is overseeing one of Africa’s most ambitious infrastructure programs: a transport and logistics corridor linking Lamu port to South Sudan and Ethiopia. Key components include crude oil pipelines, refined petroleum product lines, and LPG import terminals. This project represents a significant long-term demand driver for high-yield carbon steel flanges (ASTM A694) in Kenya.Standard ASTM A105 flanges are also consumed in large volumes in Kenya’s building and construction sector — heating, ventilation, fire suppression, and industrial compressed air systems in commercial developments in Nairobi’s Upper Hill, Westlands, and Athi River industrial areas.
Power Generation	Kenya is Africa’s leading geothermal power producer, with over 900 MW of installed geothermal capacity at the Olkaria Geothermal Complex in Naivasha, operated primarily by KenGen (Kenya Electricity Generating Company). Geothermal steam pipelines operate at high temperatures and moderate-to-high pressures, demanding carbon steel flanges in Class 600# to 900#, machined with full-face or raised-face finishes.Werner Flanges has supplied flanges to contractors working on Olkaria I, IV, and V power station expansions. ASTM A105 weld neck flanges for steam header connections and ASTM A694 high-yield flanges for wellhead assemblies are key products in this segment.
Water & Wastewater Treatment	Kenya’s growing urban population drives significant investment in water supply infrastructure. Nairobi City Water & Sewerage Company (NCWSC), the Lake Victoria South Water Services Board (Kisumu), and Mombasa Water & Sewerage Company are among the utilities procuring flanged fittings for major distribution network upgrades. ASTM A105 slip on and blind flanges in Class 150# are standard for potable water service.The Mombasa area, with its coastal industrial base, has emerging interest in desalination technology to supplement freshwater supply. Carbon steel flanges — coated for seawater environment resistance — are specified in pre-treatment and brine handling stages of desalination plants.

Frequently Asked Questions (FAQs)

q1: what is the most common carbon steel flange grade used in kenya?: astm a105 is the most commonly specified carbon steel flange grade in kenya for ambient and elevated temperature service. it is suitable for temperatures from -29°c to 427°c and is used in petroleum distribution, industrial process piping, power generation, and water infrastructure. for projects below -29°c (e.g., lpg terminals at mombasa), astm a350 lf2 is specified.
q2: do werner flanges comply with kenya bureau of standards (kebs) requirements?: kenya predominantly uses international standards (asme, astm, api, din) rather than country-specific flange standards. werner flanges’ products comply fully with asme b16.5, astm material specifications, and api standards, which are accepted by kebs and kenya’s relevant regulatory authorities. for government tenders requiring specific certification, our team can provide additional documentation as needed.
q3: what are the shipping and import duties for flanges into kenya?: carbon steel flanges are classified under hs code 7307.91 (flanges of iron or steel) for kenyan customs purposes. import duty rates under the east african community (eac) common external tariff (cet) are typically 25% for flanges from non-eac origins. werner flanges provides full commercial documentation to facilitate efficient customs clearance at mombasa port.
q4: what is the minimum order quantity for carbon steel flanges to kenya?: werner flanges has no fixed minimum order quantity (moq). we supply from single pieces (for critical maintenance spares) to full project lots of thousands of units. pricing scales favorably with volume. small urgent orders are often shipped via air freight for fastest delivery.
q5: can werner flanges provide third-party inspected flanges for kpc or kengen projects?: yes. werner flanges supports third-party inspection (tpi) at our manufacturing facility for major project clients. approved inspection bodies include tuv süd, bureau veritas (bv), dnv gl, lloyds register, and sgs. we coordinate inspection scheduling, provide inspection and test plans (itp), and ensure all test records and dimensional reports are available for the inspector’s review before release.
q6: how quickly can you deliver carbon steel flanges to nairobi for urgent maintenance?: for urgent requirements, in-stock items can ship within 24–48 hours by air freight. standard air transit to nairobi’s jkia is 3–5 days from our facility. express door-to-door delivery can also be arranged for critical shutdowns.
q7: can werner flanges supply nace-compliant flanges for sour service in kenya’s oil fields?: yes. werner flanges supplies nace mr0175 / iso 15156 compliant carbon steel flanges for sour (h2s-containing) service. compliance requirements include hardness limitation ≤22 hrc (astm a105n normalized), specific heat treatment practices, and material certification. tpi witness of hardness testing can be arranged for turkana basin upstream operations.
