Product Description

EN10305-2 E235 E355 Welded Cold Drawn Carbon Steel Tube

With high dimension accuracy and fine surface quality, cold drawn precision steel tubing is suitable for using hydraulic and pneumatic systems. Besides seamless cold drawn tubes, welded cold drawn tubes is also used for cylinder with a smooth surface. BS EN 10305, a series of steel tube specification for precision applications, 10305-2 grade E235 is a ideal material for barrel and cylinder.

 

Corresponding standards: DIN 2393 St 37-2

size range :O.D. 50 - 380 mm; W.T. 1 - 25 mm

Length: 5 - 7 m

Application: Vehicle construction, furniture industry and general engineering.

BS EN 10305-2 E235 Surface condition:

A roughness value of Ra < 0,8 μm applies to the inside surface, in compliance with ISO 4287 and ISO 4288. For the outside surface, en 10305-2 is applicable

 

BS EN 10305-2 E235 Straightness:

Tubes for hydraulic and pneumatic applications are specially straightened with regard to the intended application. For tubes with an outside diameter D > 15 mm supplied in lengths greater than 1 000 mm, the deviation from straightness of any tube length L shall not exceed:

a) 0,001 5 L for ReH ≤ 500 MPa ;

b) 0,002 L for ReH > 500 MPa

 

SHEW-E STEEL manufactured a wide range of cold drawn welded pipe products with excellent quality and services for tube related solutions. We offers specially precision steel tubes with outside diameters from 50 to 380 mm and wall thicknesses up to 25 mm to suit a wide range of applications.

 

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.

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.

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

Advantage of Our Company
