Steel tubes for hydraulic and pneumatic systems

Schierle.de offers a wide range of products and services intended for manufacturers of hydraulics, hydraulic cylinders and hydraulic pressure distributions. Based on the application

we can distinguish the following types of tubes. For more info about hydraulic cylinderclick here.

Tubes for mechanical machining - type HPZHP tubes are precision seamless tubes for the production of hydraulic cylinders or seals of 

piston rods. 'he inner working surface is obtained by mechanical machining, by honing orpeeling and subse(uent rolling.

Tubes intended for direct use in the cylinders – type HPHP tubes are seamless tubes with a precisely machined inner surface, which are primarilyintended for the manufacture of hydraulic cylinders. 'he inner working surface is achieved

by peeling and subse(uent rolling of the inner surface of the tubes.

Tubes intended for piston rods and telescopic cylinders - type HPKHP) tubes are cold drawn seamless tubes for piston rods, telescopic cylinders and cylinder

liners. *se of tube piston rods and pistons is often preferable than the use of solid materials.*se of the tube material, which e+hibits the same resistance to load stress, bending and in

torsion, means a significant reduction in the weight of the cylinder.

Tubes designated for hydraulic and pneumatic pressure distribution - type HPL

HP$ are seamless cold drawn steel tubes that are used in pressure distributions and circuits,in hydraulically and pneumatically operated e(uipment. 'he speed and pressure of the

medium are significantly changing and these devices have characteristic pressure surges onthe inner surface of tubes.

High demands are placed on production and screening of these tubes. Schierle possess the

necessary certificates of (uality management system and product certificates.
