Industries and Applications We Supply

Industry	Applications
Oil & Gas Industry	Kenya’s upstream oil sector, centered on the Lokichar Basin in Turkana County where Tullow Oil has identified substantial proven reserves, is driving significant demand for high-integrity pipeline flanges. The East African Crude Oil Pipeline (EACOP) — connecting the Lokichar fields to the Lamu Port — will be one of the longest heated crude oil pipelines in the world and requires hundreds of thousands of flanged connections across its route.Weld neck flanges are specified throughout this project for their ability to handle the elevated temperatures required to keep waxy crude oil flowing, combined with the high-pressure ratings needed for long-distance pipeline pumping. Werner Flanges supplies ASTM A105 and A182 F11 weld neck flanges for upstream gathering lines, trunk pipeline tie-ins, block valve stations, and pump station piping associated with Kenya’s oil development.For offshore exploration activities in Kenya’s Indian Ocean blocks — operated by companies including Shell, Eni, and FAR — subsea and topsides weld neck flanges in duplex and super duplex grades are required for seawater and produced fluid handling in highly corrosive marine environments.
Pharmaceutical & Chemical Processing	The Kenya Petroleum Refineries Limited (KPRL) facility in Mombasa — although currently on care and maintenance — and associated petroleum product handling infrastructure require ongoing maintenance and replacement flanges. Any future refinery rehabilitation or new downstream investment in Kenya will generate significant weld neck flange demand across all pressure classes and material grades.
Power Generation	Kenya is a world leader in geothermal energy, with the Olkaria Geothermal Complex in the Rift Valley being one of the largest geothermal facilities in Africa. KenGen and GDC operate multiple geothermal plants with a combined capacity exceeding 900 MW, and expansion projects are ongoing.Geothermal steam piping operates at elevated pressures and temperatures, with highly corrosive steam containing hydrogen sulfide (H₂S) and carbon dioxide (CO₂). Weld neck flanges in ASTM A182 F22 and F321 grades are used throughout Olkaria’s steam gathering networks, power house piping, and reinjection systems. The weld neck design’s ability to accommodate thermal cycling without stress concentration makes it the standard flange type for Kenya’s geothermal steam systems.
Water & Wastewater Treatment	Kenya’s ambitious infrastructure programs — including Nairobi’s Ruiru Dam expansion, the Northern Collector Tunnel project, and numerous water authority distribution upgrades — use large quantities of flanged piping in water intake, treatment, and transmission systems. ASTM A105 carbon steel and F316L stainless steel weld neck flanges in 150# and 300# classes are the standard specification for Kenya’s water sector projects.Mombasa’s desalination plants and coastal water supply infrastructure require F316L stainless flanges with enhanced chloride resistance, supplied by Werner Flanges with full material certification as required by Kenya’s Water Services Regulatory Board (WASREB).

q4: are nace mr0175 compliant flanges available for kenya sour service applications?: yes. for oil and gas applications involving hydrogen sulfide (h₂s) — sour service — werner flanges supplies nace mr0175 / iso 15156 compliant weld neck flanges with hardness testing and certification. this is relevant for kenya’s upstream oil sector in turkana and any sour gas processing applications.
q5: can you supply weld neck flanges for geothermal steam service in kenya?: yes. we have extensive experience supplying flanges for geothermal steam service, including astm a182 f22 and f321 grades for high-temperature steam lines. we understand the specific corrosion challenges posed by kenya’s geothermal steam chemistry and can advise on appropriate material selection for olkaria and other rift valley geothermal projects.
q6: is third-party inspection available before shipment?: yes. we coordinate pre-shipment inspection with all major tpi agencies including bureau veritas, tüv, lloyd’s register, sgs, and intertek. project-nominated inspection bodies are also accommodated. inspection plans with hold and witness points can be agreed during order placement.
q7: what is the minimum order quantity for kenya export orders?: there is no fixed minimum order quantity. we supply everything from small maintenance replacement orders to full project packages. delivery is optimized for larger volumes, but our export team can advise on the most cost-effective shipping consolidation strategy for smaller orders.
