PIPING STRESS ANALYSIS

In Nor-Par's sales area, TRIFLEX® Windows is market leader in Norway, Denmark, Poland, Slovak Republic, Romania and Bulgaria.

TRIFLEX® Windows Pipe Stress Analysis Software considers the effect of: Temperature, Pressure, Weight of the Piping system, Anchor and/or Restraint movements, Support friction, Ice/snow, Wind, Seismic events and transient loadings.

Then TRIFLEX® Windows calculates: Deflections & Rotations, Forces & Moments, Piping Code Compliance Report(s), Piping Loads acting on Rotating Equipment comparing them with allowables in published standards, Sizes Engineered Spring Hangers, Performs Flange Loading checks to determine leakage possibilities .TRIFLEX® Windows offers Engineers an Expandable Network Wide solution to meet today's Piping requirements for the Chemical, Petro-Chemical, Refining, Power, Pipeline, Pulp & Paper, Food Processing and Shipbuilding industries.

Direct and advanced interfaces between major 3-D CAD systems and TRIFLEX® Windows are available.

TRIFLEX® Windows produces Isometric Drawings and Stress Isometric Drawings in AutoCAD DXF format

PIPENET Transient has direct interface with TRIFLEX® Windows Dynamics. 

TRIFLEX® Windows is a world recognized standard for Pipe Stress Analysis. TRIFLEX® Windows features new, improved and dynamic graphics and much more - 3D color modeling & rendering, Code Compliance Standards (including the EURO Code and EURO database of piping components), Pipe Stress Calculations as well as Spring & Hanger sizing.

FEATURES

• Menu driven screens with extensive on-line help
  • English/International unit conversions
  • Underground Soil Modeling
  • Soil stiffness and automatic soil resistant spacing per ASME B31.1, Appendix VII guidelines
  • Axial, Lateral, Transverse (Up and Down) soil restraints with nonlinear soil stiffness for 4 different pipe movements
  • You can easily modify soil stiffnesses and spacing
• TRIFLEX sustained stress and displacement stress calculation "automatically" consider if pipe moves away from a restraint in the operating analysis
• Comprehensive interface to Intergraph PDS, Calma Dimension III, Plant-4D, and CADPIPE plant design systems for transfer of geometry and physical properties data
• Built-in data bases with user definable options for nonstandard materials and vendor specific valve & flange weights
• AISC structural shapes included in database
• Advanced FRP pipe analysis
• Screen option to use operating temperature modulus of elasticity for analysis of high temperature systems
• Modeling of Jacketed Piping
• Advanced coding features for faster model input
  • Automatic handling of skewed piping with restraints
  • Copy, renumber, and move blocks of nodes
  • Automatic handling of mitered elbows
  • Code to midpoint of valves and flanges
  • Merge separated jobs
  • Multiple restraint directions can be input on the same data input screen as geometry and physical properties
• Anchor element allows different stiffnesses in all 6 degrees of freedom on one screen with option to "automatically" calculate anchor displacement
• Built-in buoyancy with offshore riser design codes
• Pitch and Roll to vary gravity axis
• ASME Section 3 analysis for calculation of nozzle and branch connection stresses and flexibilities
• SIF and Flexibility Factor equations included
• Automatic spring hanger sizing with piping analysis or stand alone matched with other vendor tables
• Nozzle release option at equipment connections for spring hanger sizing
• Directional restraints, limit stops, and friction can easily skewed using "tilt" options
• Limit stop element allows different gap spacing in each direction with restraint stiffness option
• Dynamic Analysis: Mode shapes and frequencies, response spectrum, and "true" time history analysis with integrated waterhammer and relief valve synthesizers. Unique closed form solution algorithms provide the most accurate technology available for analyzing piping responses to slug flow, waterhammer, steam thrust, and other transient loads.
