BS EN 10305-4 Steel Tubes For Precision Applications Seamless Cold Drawn Tubes for Hydraulic And Pneumatic Power exporters, BS EN 10305-3 Steel Tubes For Precision Applications Welded Cold Sized Tubes Manufacturer.
What is EN 10305-3 E190 tubes?
BS EN 10305-3 is the standard specified outside diameter ≤ 193,7 mm. 12 000 m tube with an outside diameter of
40 mm and a wall thickness of 1,5 mm, made of steel GR.
EN 10305-3 specifies the technical delivery conditions for welded cold sized steel tubes of circular cross
section for precision applications.
It can also be applicable to non-circular (excluding square and
rectangular) cross sections. Tubes according to EN 10305-3 are characterized by having precisely defined
tolerances on dimensions and a specified surface roughness. Typical fields of application are in the vehicle,
furniture and general engineering industries.
Manufacture: the tubes shall be manufactured from steel strip by electric welding. The tubes
shall not include welds used for joining lengths of flat rolled strip prior to forming the tube, except for
coiled tubes which may be supplied in the delivery conditions +A and +N. Surface conditions: S1 (black); S2
(pickled); S3 (cold rolled); S4 (coated to an agreed condition). The surface conditions S1 and S3
apply for the strip. The surface condition S2 and S4 may apply for the strip or the tube.
