  • STO 10.001-2009, RD 10-400-01: Modified friction analyses. When analyzing fatigue failure, cold state friction factor is set as 50% of working state friction factor. When analyzing cold state, friction coefficient is set as 100%. This allows the consideration of the friction factor's fluctuation over heating and cold cycles. In prior versions, friction factor was set as 50% for cold state analysis; therefore, stresses in cold state will be higher in version 4.63

  • RD 10-400-01, SA 03-003-07: Stress intensification factor and bending factors for bends in cold state no longer take into account pressure, since pressure is not considered in cold state. As a result, defectiveness and stress in branches in cold state will be higher, and forces in cold state will also change

  • All branches are now analyzed for bending and internal pressure. Branch types are changed from "bend", "flange", "welded" to "elbow", "bend", "miter", "extruded". New properties are added for branches (number of miter joints, weld quality factor, presence or absence of flanges, weld position relative to branch plane). START 4.60 and lower files use bends for branches with a radius of less than 2D and branches with flanges, while branches with a radius of more than 2D are changed to bends. Welded branches are replaced by miter branches, where the number of miter joints is automatically determined in order that the skew angle is 22.5 or 15 degrees. We recommend reviewing, and if necessary editing, outdated file versions.
  • Total allowance is change to two parameters for all pipes and fittings - "corrosion allowance" and "mill tolerance". START 4.60 and lower files automatically set mill tolerance as 10% of wall thickness, while the rest of total allowance is taken as corrosion allowance. Mill tolerance and corrosion tolerance combined always equal total allowance. We recommend reviewing, and if necessary editing, outdated file versions.
  • Added pressure analysis for miter and extruded branches using RD 10-249-98 in START-Elements and START-Base
