ST52 EN10305-2 WT0.5 Precision Steel Tubes Mechanical Welded Steel Tube

ST52 ST45 ST35 EN10305-2 Precision Steel Tubes Mechanical Welded Steel Tube

Description:

Precision steel tubes, specifically mechanical welded steel tubes, are engineered for high strength and durability. They feature seamless construction that ensures uniformity and dimensional accuracy, essential for various applications. These tubes exhibit excellent resistance to corrosion and wear, making them suitable for demanding environments. Their precision manufacturing process allows for lightweight yet robust designs, ideal for automotive, construction, and industrial uses. With superior weld integrity and consistent performance, these tubes provide reliability and efficiency in mechanical systems, enhancing overall operational effectiveness.

Quick Details:

Production Process:
Cold rolling by Cold pilger machine and Cold rolling machine
 

Delivery Condition:
1.+C No heat treatment after the final cold drawing process
2.+LC After the final heat treatment there is a suitable drawing pass
3.+SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
4.+A After the final cold drawing process the tubes are annealed in a controlled atmosphere
5.+N After the final cold drawing operation the tubes are normalized in a controlled atmosphere

Production Method:
The cold drawn welded tube is produced by drawing ERW (electric resistance welded tube).During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.

Advantage (compare with seamless cold drawn tube):
1.Better shape
2.Improved quality surface
3.Tight Excentricity and wall thickness tolerances (the eccentric
4.Tube more safety
5.Good toughness at low temperature
6.USA Market: 90% of the cylinder in the USA market are produced with welded tubes
7.Cost fix Lengths More Cheaper
