Briefing

The cold rolled welded tubes have closer dimensional tolerances, better surface finish and higher mechanical properties.

Detailed

1. Applications:

Agricultural oil cylinder (<200bar), more fuel-efficient cylinder, stabilizer, load cylinder, steering system.

2. Quality Standards:

EN10305-3 Welded cold size tubes

DIN 2393 Welded Precision Steel Tubes

ASTM A513 Standard Specification for Electric Resistance Welded Carbon and Alloy Steel Mechanical Tubing

3. Steel Grades:

GB Standard: 08, 08F, 08Al, 10#, 20#, Q195, Q235
JIS Standard: SPCC, SPHC
EN Standard: E195, E235, E275, E355
DIN Standard: St12, St37, ST52.3
ASTM Standard: 1010, 1020, 4130

4. Tolerance of Dimensions:

Inner DiameterH9, H10
Inner surface roughness: Ra 0.80u max

Eccentricity: 3% max

5. Process:

The cold rolled welded tube is produced by rolling ERW (electric resistance welded tube) through a die and over a mandrel plug. 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.
