EN 10305-4 Standard Steel Pipe for hydraulic and pneumatic power systems
The steelmaking process of EN10305-4 is at the discretion of the manufacturer and steels shall be fully killed. The tubes shall be manufactured from hot finished seamless tubes by cold drawing. Other suitable methods of cold working are permitted. The tubes shall be delivered in the delivery condition +N which means that after the final cold drawing operation the tubes are normalized in a controlled atmosphere.
EN10305-4
seamless precision bending steel tubes of hydraulic systems
Size: 6-100mm
Delivery condition: +N, +C,+LC, +SR, +A

packing
6.Deliver condition:
+N After the final cold drawing operation the tubes are normalized
in a controlled atmosphere
Please specifiy the final heat treatment when sending the enquiry.7.Inspection and testing:
Chemical analysis
Tensile test
Flattening test or Drift expanding test
Dimensional inspection
Visual examination
NDT for verification of leaking tightness
