E235 EN10305-2 OD50 Seam Removing Welded Steel Tube Round Shape For Telescopic Cylinders

Cold Draw Precision Weld Steel Tube

Description:

Cold Draw Precision Weld Steel Tube is manufactured through a precise cold drawing process, ensuring high precision and consistent wall thickness. Ideal for applications requiring high mechanical strength and durability.

Produced by cold drawing over mandrel and die on the ERW welded steel tube, to achieve better tolerance and good concentricity, both outside and inside weld seam is completely removed during the cold drawing process.

Delivery Condition:

+N After the final cold drawing operation the tubes are normalized in a controlled atmosphere.

+C No heat treatment after the final cold drawig process.

Packaging:

Plastic bag inside, wooden box outside( or as costomer requirements).
