Sizes of tubes for hydraulics
Tubes for mechanical machining – type HPZ are precision seamless tubes for the production of hydraulic cylinders or seals of piston rods.
Tubes intended for direct use in the cylinders – type HP are seamless tubes with a precisely machined inner surface, which are primarily intended for the manufacture of hydraulic cylinders.
Tubes intended for piston rods and telescopic cylinders – type HPK are cold drawn seamless tubes for piston rods, telescopic cylinders and cylinder liners.
Tubes designated for hydraulic and pneumatic pressure distribution – type HPL are seamless cold drawn steel tubes that are used in pressure distributions and circuits, in hydraulically and pneumatically operated equipment.
Zinc coated precision steel tubes (galvanized tubes) are destined for hydraulic and pneumatic pressure distribution (so called HPL tubes), production of automobile components, utility vehicles as well as for production of machine products such as fittings and joints.
Dimensions and weights of HP tubes– outside diameter x wall thickness (OD x WT):

- ready to use – HP *
Dimensions and weights of HPZ tubes suitable for mechanical treatment– outside diameter x wall thickness (OD x WT):
- 50.0 x 5.0 – 130.0 x 7.5 mm
