| GMF A/S is a quality-conscious partner and general leader when it comes to quality, but we are also able to deliver the extra quality customers demand. GMF A/S is ISO 9001 certified and satisfies all the requirements of EN253 and EN448. GMF A/S satisfies FW401 standards at customer request. Bevel cutting of pipe, cold bending: Thickness of material < 3.2 mm (nominal thickness) is not bevelled. Thickness of material > 3.2 mm is bevelled 30° -0/+5, plane 1.6mm +/-0.8mm Qvality according to EN448: The max. tolerated ovality in the bend zone is 6%. 
Maximum ovality at pipe ends: The tolerance for ovality at pipe ends is in accordance with EN 253 and EN10217-2.
Ovality is measured as a two-point measurement of the diameter and may not exceed:
Outside diameter ≤ 219.1 ± 1% or 0.5 mm – whichever is greatest
Outside diameter > 219.1 ± 0.75 % Deviation in relation to angle of bend: Outside diameter ≤ 219.1: 90° ± 2.0°
Outside diameter ≤ 219.1: 90° ± 1.0° Wall thickness in the bend zone is not reduced to less than 85% of nominal thickness in accordance with EN448. Gross list: | Properties | All ends are deburred.
All ends are undamaged.
Deformations: The difference in height between bumps and dents will not exceed 25% of the actual wall thickness used.
The difference in height naturally includes the height in the angle of the bend.
Scratches: The min. wall thickness and the min. wall thickness in the bend zone will be monitored at all times.
Rust grade up to B level in accordance with ISO 8501:1:2007 EN 448:2009 | | Materials | Steel quality in accordance with EN10217-1, EN10217-2, EN10217-3, EN10216-2, EN10216-3, EN10216-4, ASTM, ANSI
| | Traceability | All bends are marked with a charge/heat number at one end in accordance with 3.1 (EN10204/3.1). | |
