2 This marking is used in lieu of a works certificate DIN 50 049-2-2. Test Class 1 DIN 17458 Table 7 applies for tubes made of and Mechanical PropertiesSteel Types, mechanical properties and conditions are listed in Table Suitability and Weldability: Steel tubes of St. , R Series, are weldable according to usual techniques. Not recommended to weld St. , R-VZ series, Zinc Chromium-6 Free plated steel tubes of are suitable for arc welding. The welding filler should be selected in accordance with DIN 8556 part 1 taking into account the type of application and the welding and InstallationPlease refer to Section T for the assembly and installation in-structions for Metric Tube R1 Parker Steel tubes mechanical properties and conditionsNote: Interpolation is acceptable for intermediate temperautre R2 Parker stainless tube elevated temperature derating factorsApplicationsRecommended Bend RadiusA bend radius of 3 times the tube or greater is recommended for cold bending of Parker tubes with hand, mechanical and power bending of Tube SupportsThe use of VH tube supports for EO and EO-2 fittings is required in certain thinner wall tubes to ensure proper assembly.

3 Consult the tube Range Parker steel (St. ) Metric seamless tube can be used at the full rated working pressures without pressure rat-ing reductions within the following temperature range: -40 C to +120 C. Maximum allowable operating tempera-ture of +250 C. Parker stainless steel ( ) Metric seamless tube can be used at full rated working pressures with-out pres-sure reductions within the following temperature ranges: -200 C to 350 C (-60 to +20). Maximum allowable operating temperature of +400 C. Elevated temperature pressure reductions are as listed in Table Delivered Conditions:Standard Tube Lengths: 6 meters (approx. 20 ft)Surface Finish: Steel (St. ): Phosphated and oiled dimensions 5 mm, outside and inside oiled dimensions 6 mm and higher, outside and inside phosphated and oiled Steel (St.)
