ROHR2 Feature list Page 20 4 ROHR2 - Detailed features 4.1 Overview All ROHR2 program versions include • ROHR2WIN Graphical user interface • ROHR2 Calculation program • HPGLWIN HPGL-file Graphic-interpreter • ROHR2FED Spring hanger design • ROHR2flange flange design • Internal pressure analysis can be accomplished for straight pipe, pipe bend and tees according to AD, TRD and EN 13480 (only for materials acc. To DIN and EN) • Neutral Interface to communicate with CAD-systems • The graphical user interface is available in German or English • The results may be printed out in German, English or French.

ROHR2 Feature list Page 21 4.2 Input features System input • Input of system geometry by mouse and keyboard • Zoom, pan and rotate functions • UnDO and ReDO • Quick access to frequently used commands by context menu. Detailed Input features • Definition and assignment of boundary conditions and loads with the mouse by means of dialog windows. • Support conditions can be entered by definition of sliding support, guide support, axial stop, anchor point. The support directions are determined automatically. • Input of internal supports and hangers (i.e. Supports and hangers where the base point is a system node). Internal spring hangers and supports are analyzed like “normal” spring hangers and –supports. • Input of angulating supports with any characteristic curve. • Special coordinate systems for boundary conditions are produced automatically if required. • Free input of dimensions of pipes and structural steel sections, the data can be taken from the enclosed databases. The line masses of pipes, insulation and medium are determined. • Sectional data of the common structural steel sections are determined automatically or read from a sectional data file (DIN). • Material properties like Young´s modulus, αt and allowable stresses may be taken from the ROHR2 database MATDAT (may be extended by the user) • Input of components like instruments, expansion joints and flanges. The increased stiffness of the instruments is considered by 3 ⋅ s of the associated diameter. • Stiffness of supports, controlled by the user. Data can be taken from database (VDI 3842/2004) or manually entered • Management of pipe names • Modeling of soil restrained with non-linear properties • Modeling of jacket piping, considering the couplings Databases • Databases with data e. g. of pipes, bends, flanges or expansion joints according to technical standards or according to manufacturer’s data. Databases are extendable by the user himself. The delivery includes: Pipes: ANSI B36.10, EN 10220, DIN 2448, DIN 2458, Bends: EN 10253-2 , ANSI B16.9, DIN 2605 part 1, DIN 2605 part 2 Flanges: EN 1092-1, ANSI B16.5, DIN 2627 - DIN 2638 Blind flanges: EN 1092-1 Reducers: EN 10253-2, DIN 2616 part 1, DIN 2616 part 2 Tees: EN 10253-2, DIN 2615 part 1, DIN 2615 part 2 Expansion joints: HYDRA (Witzenmann), BOA (IWK) Heads EN 10253-2, DIN 28011, DIN 28013, DIN 2617 Visco dampers: GERB series VES, RHY • Spring hangers supports: HYDRA (Witzenmann), LISEGA, PSS (Grinnell), PipeSupportsGroup, HESTERBERG, SSG Determination of loads: Wind according to DIN 1055 part 4, DIN 4133, EN1991, NV65, UBC, IS875 or by user defined wind pressure tables Snow and ice loads: DIN 1055 • Stiffness of supports according to VDI 3842/2004 • Databases for rigid supports, couplings (jacket pipes) and instruments can be created by the user himself.
