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.

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
