Flanges
• DIN flanges, generally manufactured in carbon steel with quality ST37.2 (1.0038), with the following characteristics:
- Tensile strength Rm, (N/mm2): 340 to 510
- ReH minimum yield stress, min (N/mm2): 210
- Elongation at break, min (%): 17
- Type R deoxidation (calm)
- Chemical composition, plus (%): C (0.23), P (0.060), S (0.060), N (0.010)
The chemical composition of the finished product and its mechanical properties depend on the product's thickness. For thicknesses greater than 100 mm, the quantity's value in question must be agreed at the time of the order.
The ability for fusion welding is determined by its tendency to harden by sudden cooling and by the carbon content (carbon contents higher than 0.22% in melt analysis are not recommended). Likewise, said material also has aptitude for butt welding and for pressure welding with gases.

- DIN 2631-2632-2633-2634-2635 Vorschweiβflanche. Nenndruck 6/10/16/25/40
• Flanges EN 1092-1, generally manufactured in carbon steel with P245GH quality (1.0352), have the following characteristics:
- Tensile strength (N/mm2): 410 to 530.
- Yield stress, min (N/mm2): 220/245 (depending on thickness)
- Elongation at break, min (%): 23/25 (depending on thickness)
- Semi-killed steel
- Unalloyed steel
- Chemical composition, plus (%): C (0.20), Si (0.40), Mn (1.30), P (0.025), S (0.015)
In relation to the suitability for welding, it must be taken into account that the steel's behavior during and after the welding depends not only on the material, but also, among other factors, on the product's dimensions and on the welding personnel's competence (Qualification of welders according to EN 287 and EN 1418).
• Flanges ASME B16.5, generally manufactured in carbon steel with ASTM/A105M quality, with the following characteristics:
- Tensile strength, min (N/mm2): 485.
- Yield stress, min (N/mm2): 250.
- Elongation at break, min (%): 22/30 (depending on thickness)
- Semi-killed steel
- Unalloyed steel
- Chemical composition, plus (%): C (0.35), P (0.035), S (0.040), Cu (0.40), Ni (0.40), Cr (0.30), Mo (0.12), V (0.08), Si ( 0.10-0.35), Mn (0.60-1.05)
Rubber compensators
They are specially indicated to eliminate noise and absorb vibrations in pipes, also being excellent devices to connect misaligned pipes or reduce water hammers. Depending on the service conditions, we can adapt to your needs (pressure, vacuum, movement and temperature).
Malleable iron accessories
Standard and use of manufacture EN 10242: 1994 (Class "A").
