  • 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-PROF 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 We recommend reviewing, and if necessary editing, outdated file versions.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-PROF 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 We recommend reviewing, and if necessary editing, outdated file versions.
