Leave a message
GNEE Steel produces round stainless steel welded tubes according to EN10296-2 standard specification, stainless steel materials have 1.4301 (304), 1.4307 (304L), and 1.4404 (316L) grades, with a large range of sizes, EN 10296-2 stainless steel welded tube is wide used for mechanical purpose, a typical application is for automotive exhaust system.
EN 10296-2 Stainless Steel Welded Tube Manufacturing
Tubes shall be produced from hot or cold rolled strip or plate/sheet, longitudinally welded across the abutting edges, by a continuous automatic process with or without the addition of filler metal.
EN 10296-2 Stainless Steel Welded Tube Delivery Conditions
Tubes produced shall be delivered in the following delivery conditions:
- Ferritic steels: as welded (+AR) or annealed (+A), at the discretion of the manufacturer;
- Austenitic and austenitic-ferritic steels: as-welded (+AR) or solution annealed (+AT), as specified by the purchaser.
Option, the tubes shall be supplied pickled.
EN 10296-2 Stainless Steel Welded Tube Appearance
Tubes shall be free from external and internal surface defects that can be detected by visual examination.
The internal and external surface finish of the tubes shall be typical of the manufacturing process and, where applicable, the heat treatment employed. The finish and surface condition shall be such that any surface imperfections requiring dressing can be identified.
It shall be permissible to remove surface imperfections only by grinding or machining provided that, after so doing, the tube thickness in the dressed area is not less than the specified minimum wall thickness. All dressed areas shall blend smoothly into the contour of the tube.
Surface imperfections which encroach on the minimum wall thickness shall be considered defects and tubes containing these shall be deemed not to conform to this document.
For tubes with an outside diameter D greater than or equal to 114,3 mm, repair of the weld shall be permitted, provided that a compatible filler metal is used. Such weld repairs shall not exceed 20 % of the seam length.
EN 10296-2 Stainless Steel Welded Tube Inspection And Testing
- Cast analysis
- Tensile test
- Flattening test
- Drill expanding test
- Bend test
- Ring tensile test
- Weld bend test
- Dimensional inspection
- Visual examination
- Leak tightness test (option)
- Non- destructive test of weld (option)
EN 10296-2 Stainless Steel Chemical Composition (% By Mass – Max Unless Stated)
Ferritic, austenitic, and austenitic-ferritic (duplex) stainless steel grades and austenitic heat resisting grades are included in the range of grades specified in this standard.
