Leading Flange Manufacturer & Exporter
to Kenya
Werner Flanges serves Kenya as a premier manufacturer and exporter of industrial flanges, delivering world-class piping components to East Africa's most dynamic economy. As Kenya accelerates infrastructure development under Vision 2030, invests in oil and gas exploration in the Turkana Basin, and expands its manufacturing and utility sectors, demand for high-quality flanges meeting international standards has never been greater. Werner Flanges supplies carbon steel, stainless steel, alloy steel, and duplex flanges to Kenyan contractors, engineering procurement companies (EPCs), and industrial operators across Nairobi, Mombasa, Kisumu, Eldoret, and Nakuru.
Our flanges are manufactured to ASME B16.5, ASME B16.47, MSS SP-44, and API 6A standards, covering sizes from ½” to 60″ NPS in pressure classes 150# through 2500#. Materials include ASTM A105 carbon steel for general-purpose industrial service, ASTM A350 LF2 for low-temperature applications, ASTM A182 F304/F316 stainless steel for corrosion-resistant service in Kenya’s coastal and chemical environments, and ASTM A182 F11/F22 alloy steel for elevated-temperature process applications.
As a direct manufacturer, Werner Flanges eliminates distributor markups, providing Kenyan buyers with competitive pricing, complete material traceability, and EN 10204 Type 3.1 material test certificates. We ship to Mombasa Port — Kenya’s primary international gateway — via sea freight in 20–28 days, with expedited air freight options to Jomo Kenyatta International Airport (Nairobi) available for urgent project requirements. Our documentation packages satisfy Kenya Revenue Authority (KRA) import requirements, Kenya Bureau of Standards (KEBS) specifications, and client quality assurance protocols for international-standard projects.
From geothermal energy developments in the Rift Valley to petroleum infrastructure supporting Turkana oil export, from Mombasa's expanding port and industrial zone to Nairobi's urban water and district cooling networks, Werner Flanges delivers the piping component quality Kenya's industries require to operate safely and efficiently at international standards.

Industries and Applications We Supply
| Industry | Applications |
|---|---|
Oil & Gas (Upstream & Midstream) |
Kenya’s upstream oil sector centers on Tullow Oil and Africa Oil’s Turkana assets, with the KCOP pipeline project requiring carbon steel flanges from 6″ to 36″ NPS in Class 300# through 900# across hundreds of kilometers of mainline pipe, pump stations, block valve stations, and the Lamu marine terminal. Werner Flanges supplies API 5L-compatible weld neck flanges, NACE MR0175-compliant carbon steel for produced fluid service, and alloy steel flanges for gas compression facilities.
Downstream, the Kenya Petroleum Refineries facility at Changamwe, Mombasa — though operating at reduced capacity — and petroleum product import terminals at Kipevu Oil Terminal use carbon steel and stainless steel flanges throughout storage, blending, and dispatch systems. |
Geothermal Energy |
KenGen operates Africa’s largest geothermal facility at Olkaria in the Rift Valley, and the Menengai Geothermal Project adds further capacity. Geothermal wells produce superheated steam at pressures up to 40 bar and temperatures exceeding 250°C, with entrained non-condensable gases including CO2 and H2S creating aggressive corrosion environments. Werner Flanges supplies Class 300# and 600# alloy steel weld neck flanges for wellhead and steam gathering systems, stainless steel flanges for acid condensate handling, and carbon steel Class 150# flanges for lower-pressure steam distribution to turbine halls. |
Water & Sanitation Infrastructure |
Kenya’s water sector, managed by the Water Services Regulatory Board (WASREB) and county water utilities, is investing heavily in treatment plants, pumping stations, and transmission mains to close the urban/rural supply gap. Werner Flanges supplies Class 150# carbon steel weld neck and slip-on flanges for pump station piping at Nairobi’s Gigiri and Kabete treatment plants, large-diameter flanges for raw water transmission from Sasumua and Ndakaini dams, and stainless steel flanges for chemical dosing systems in water treatment.
The Nairobi Rivers Sewerage Improvement Project and similar urban sanitation programs under NEMA oversight incorporate flanged connections at pump stations, odor control units, and treatment process equipment. Class 150# carbon steel and glass-reinforced plastic (GRP) flanges dominate these lower-pressure applications. |
Power Generation |
Beyond geothermal, Kenya generates power from thermal (HFO, diesel, gas), hydroelectric, wind, and increasingly solar sources. The Olkaria-Lessos-Kisumu transmission expansion and thermal backup plants at Kipevu use carbon steel flanges throughout steam, fuel oil, and cooling water systems. Wind power facilities at Ngong Hills and the Lake Turkana Wind Power project (310 MW — Africa’s largest wind farm) incorporate carbon steel flanges in gearbox cooling, hydraulic pitch systems, and site utility piping. |
Frequently Asked Questions (FAQs)
- q1: do you supply flanges compliant with kenya bureau of standards (kebs) requirements?
- yes. we coordinate kebs pre-export verification of conformity (pvoc) certificates through kebs-recognized inspection agencies prior to shipment, ensuring your consignment clears mombasa port without kebs compliance holds. our flanges meet the underlying astm and asme standards that kebs adopts as the basis for its technical regulations.
- q2: can you supply flanges for the kenya crude oil pipeline (kcop) project?
- absolutely. werner flanges is positioned to supply astm a105 and a694 carbon steel weld neck flanges, class 300# through 900#, in sizes from 8″ to 36″ nps, compliant with api 6a, asme b16.5, and nace mr0175 requirements for the kcop project. we can work with project epcs to develop material submittals, inspection and test plans, and documentation packages satisfying international oil company (ioc) specifications from tullow oil and africa oil.
- q3: what is the minimum order quantity for kenya?
- werner flanges accommodates both small orders (single items for maintenance) and large bulk orders for project procurement. there is no hard minimum, though sea freight economics favor consolidated shipments. small urgent orders are cost-effectively shipped via air freight.
- q4: do you have local stock or a warehouse in kenya?
- werner flanges operates as a direct-from-factory exporter without local kenyan warehousing. this model keeps costs low and ensures product freshness. for projects requiring local stock buffer, we can discuss a bonded warehouse arrangement or consignment agreement with a kenyan logistics partner.
- q5: can werner flanges supply flanges for geothermal applications at olkaria?
- yes. we supply astm a182 f11 and f22 alloy steel flanges and astm a182 f316 stainless steel flanges suitable for geothermal steam gathering, wellhead connections, and separator systems. we understand the demanding service conditions at olkaria — high-pressure steam, non-condensable gas (co2, h2s), and aggressive condensate — and can recommend appropriate materials and pressure classes for your specific well conditions.
