Precizne hidravlicne cevi - brezšivne, EN 10305-4 (DIN 2445/2)

*calculated in accordance with DIN 2413 validity range III for dynamic loading P = 20 x K x s x c/(S x (da + s x c)) (bar). Material parameter K = 226 N/mm² (torsional endurance). Safety factor S = 1.5 for static and dynamic loading. Factor c to take into account the wall thickness deviation for static and dynamic loading = 0,8 for tubes with outside diameters of 4 and 5; 0,85 for tubes with outside diameters of 6 and 8; and 0,9 for larger tube outside diameters.
Notes: The stated calculated pressures do not take into account any corrosion surcharge. Tubes with a diameter ratio (OD/ID max) of >= 1.35 have also been calculated for a predominantly static load in accordance with DIN 2413 validity range III, but with K = 235 N/mm². **Oiled instead of phosphatised
