Tubes for Hydraulic Cylinders


We provide tubes and components in carbon, micro-alloyed and special alloy steels for hydraulic cylinders and accumulators.

A Complete Range of tubes for Hydraulic Cylinders barrels and Accumulators

Tenaris produces a wide range of hot-rolled and cold-drawn tubes and components in carbon, micro-alloyed and special alloy steels used as hydraulic cylinder bodies, piston rods, telescopic cylinders and cylinder accumulators in earth moving machine, wind mills and cranes leading manufacturers.

A Long-Term Experience in Product Development

Tenaris has decades of experience in product development of tubes for hydraulic cylinders.

A completely integrated manufacturing cycle, specialized production lines, a dedicated R&D center in Dalmine, Italy allowed us to develop a complete product portfolio to fulfill the most demanding customer requirements.

In partnership with our customers, we have developed high-performance products that are full-scale tested in our laboratories, simulating the most severe working conditions. These include low temperatures and high working pressures, verified through fatigue tests with real load spectra, both on the pipe body and hydraulic cylinder components as well as burst tests, failure mode analysis and others.

An extended Dimensional Range

As seen in table 1 Tenaris can offer a unique dimensional range both for hot-finished and cold-drawn tubes. Thanks to the installation of an innovative drawing bench, we can now offer tubes up to 390 mm OD and 30 mm WT.

Our tubes for hydraulic cylinders and accumulators are characterized by tight dimensional tolerances, controlled surface quality, high steel cleanliness and guaranteed eccentricity.

Safety and Enhanced Fatigue Life in Extreme Working Conditions

Setting up chemistry, surface quality, special production cycle, Tenaris has developed high-performance proprietary grades to be used in extreme conditions in terms of high working pressure, low temperature guaranteeing high fatigue life (HC540, HC650 proprietary steels), that is 50 % above the performance of a standard product.

Service Performance and Vertical Integration

Thanks to our integrated industrial system, from the steel-shop to the final component, we can guarantee excellent results in terms of promised performance ( > 95% in the last years).

In order to optimize the customer supply chain, we can supply hydraulic cylinders tubes and components in different conditions: cut to length - skived and rolled burnished (H8 tolerances) – turned components (ready for welding) - welded assembly (including turning, welding of the flanges and accessories, drilling and tapping the flange holes).
