Honed tubes for hydraulic cylinders are available commercially in bars between 7 and 12 metres, in a wide range of diameters and thicknesses to meet every possible design need.

PAGANI EUGENIO srl does not have a stock of products but manufactures to order a wide range of honed pipes up to D.600H8 x 660 and lengths of 6000-6200 mm.

Supply terms

  • Reference standards EN10210-1, EN10297-1, other markings on request;
  • Steel quality: E355AR, S355 J2H, E590K2, 20MnV6, other materials on request;
  • Material with 3.1 EN10204 certificate;
  • Standard production tolerances H8, H7 on request;
  • Standard roughness Ra0.20 my MAX Rt2.5 my, lower roughness values on request;
  • Mechanisation already available;
  • Straightness / concentricity;
  • STD packaging / on request.

Our production is optimised for machining pre-cut tubes which we supply with the required “mechanisation”, in other words, with an end joint and rest groove for alignment of the inside and outside diameters in preparation of subsequent lathe machining.

To complete our customer’s production cycle, we can also add other processing phases such as turning and tapping according to our customer’s drawings – if required.

Quality controls provided

  • Visual inspection;
  • Dimensional check by means of a two-point bore gauge;
  • Measurement of Ra, Rt roughness;
  • End thickness check.

On request it is possible to carry out further thickness measurements using ultrasound techniques and issuing the relevant report.

Standard packaging procedures require the application of a protective liquid inside the honed tube and protecting the ends with bubble film.

On request it is possible to supply packing options with wooden cross-members, wedges, supports and crates for international shipments.

Case history

Perfectly aligned honing

On behalf of one of our historical and most important client, we planned the definition of a production cycle combined with turning and honing which ensured the required geometries with reliable repeatability over the whole producon

Non standard tube supply

We have made some honed tubes in Inox AISI 316, for one of our customers active in the field of Oil & Gas valves actuators, that stands with a great strategic importance for the energy sector.
