Product description

Notes

The pressure figures are based on straight tubes.
The appropriate wall thickness needs to be calculated for tubes with bends as stipulated in DIN EN 13480-4.
*Stainless steel tubes are supplied in manufactured lengths according to EN 10216-5. In terms of production, these are usually 6 meters (+/- 1m). Order quantities are rounded to the nearest possible total length, without cutting.

Description

The stainless steel pipes made of materials 1.4301 / AISI 304 (V1), 1.4541 / AISI 321 (V2) and 1.4571 / AISI 316Ti (V4) are supplied in CFA condition (bright annealed) as standard. This condition offers very good bendability and is the established standard in the hydraulics sector, particularly for the installation of pipelines.
Our stainless‑steel tubes are tested according to DIN EN 10216‑5. The dimensional tolerances (Ø, wall thickness, ovality) are restricted in accordance with DIN EN 10305‑1 ranging from 4 to 42 mm in outer diameter (Ød1). Larger dimensions are classified according to EN ISO 1127 D3/T.
