Descrição do produto

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.

The steel pipes in the PR ZP, PR VZ CF PR and PR ST 52 series are supplied in the +N condition (normalised annealed) as standard. This delivery condition ensures excellent bendability and is the established standard for use in hydraulic piping systems, particularly during assembly and installation.
