Hydraulic cylinders – large-scale manufacturing in Rissa

The Servi plant at Rissa, previously known as Servi Cylinders, was set up in 1936 and commenced production of cylinders and accumulators in 1956. From the very start our products have been used for extremely demanding operations in some of the world’s harshest environments. We engage in continuous product development in order to meet our customers’ quality requirements. Our customers operate in the offshore, maritime and shipping, hydropower, smelting and general industries.

Servi offers a standard range of hydraulic cylinders, though most of our production is based on customised solutions. We supply cylinders and accumulators and dampers with piston diameters from Ø 20 mm to Ø 1500 mm and stroke lengths of up to 20 m, depending on the dimension and design of the various materials. Watch our video showing the manufacturing facilities and capacities at the Rissa factory.

Our cylinder and accumulator factory was certified in accordance with NS-EN ISO-9001:2008 in 1993. In addition, the company holds quality certificates in relation to the Pressure Equipment Directive (PED B-61 and PED D-43), type approvals (ATEX EC, CD – type approved cylinders) and MSA (certification agreements) with DNV. The company also has welding competence (IWT) and certified welders in accordance with NS-EN 287.
