Hydraulic and Pneumatic Caparo Precision Steel Tubes

Product detail:

Torich cold drawn steel tubes as per Standard: 

EN10305-4 Cold drawn tubes for hydraulic and pneumatic power systems

Which is made of Gr E215,E235,E275,E355, or other materials upon agreement with customers.

Steel Grade and Chemical Compositions Please refer blow data.

Good precision and reach specificted mechanical data to more suitable for machining .

How to realize :Cold drawing on the Seamless Steel Tubes, to reach high accuracy on the OD and WT tolerance,with certain heat treatment to achieve better mechanical properties for bending and pressure purposes

Torich steel tube provides sizeOD from 5mm(0.197'')to80mm(3.15'') WT form (0.039'') to 15mm(0.59'').

fixed length random length ,cutting length is avaliable .Max length is 12m(39.37feet),general length for 20ft gp length:5.8m(19.03feet),6.096m(20feet)

As per torich mill standard packaging In Hexagonal Bundles, wth anti-rust oil protection, with seaworthy packing

Deliver condition:

+N After the final cold drawing operation the tubes are normalized in a controlled atmosphere
Surface smoothness could be reached by EN10305-4 request Ra≤2μm, and better than standard.

Surface treatment could be:

1.Protection by phosphation

2. Protection by galvanization, and chromatization type blue-white
3. Protection by galvanization and chromatization type yellow
4. Protection by galvanization and chromatization type olive green
