5 OD to 1250 mm.When ordering tubes with R≤1.5D it is necessary to agree precision of geometrics.STRAIGHT TUBES MAXIMUM LENGTH (before bending): 26000 mm.LEG LENGTH: min 1 meter, max 10.5 meters (for max R=1250 mm)Note: other sizes are available upon agreement.HEAT TREATMENT: Stress Relieved after U bending.HYDROSTATIC TEST: maximum test pressure 600 bar, soaking 10 sec. with demineralized water. Compressed air cleaning after hydro-test.Marking: before bending by marking machine all over the tu
