Oriental Engineering Works Pvt. Ltd. was founded in Lahore (now Pakistan) in 1938 with the goal of producing cold-start horizontal diesel engines. Following India's partition, the firm was transferred to its current location. Later, the firm shifted its focus to hydraulic equipment, and the Tangee brand is still used to build high-pressure cylinders, pumps, and hydraulic systems. OEW has been the only selling agent for The Roemheld Gruppe (Germany) in India since 1988, a manufacturer for Impulse Pumps BV (the Netherlands) since 2004, and a distribution, installation, and service partner for Tractel Secalt S.A. (Luxembourg) since 2016.
