Key Features
Modelling Piping Systems
Often on the project critical path, the analysis of piping systems needs to be
performed quickly but with certainty. Aspect Pipe Stress provides various features to
help analysts develop nodal models quickly and accurately, helping to keep
project schedules on-track.
Expansion Loop Wizard
Adding an expansion loop is a common solution for high stress or loads in a piping system. Aspect Pipe Stress has tools to find the best location and calculate the size. It can use a CAD model to quickly identify a suitable location, reducing the need for repeated analysis and design. The Loop Wizard can automatically design the expansion loop based on the target value and available space.
Hanger Design and Databases
Spring hangers are crucial to supporting a piping system when balancing vertical displacements. Aspect Pipe Stress allows users to select from thirty-eight hanger manufacturer catalogues to support their piping system and balance vertical
displacements. Aspect Pipe Stress will then select the appropriate hanger based on the load and movement at the hanger location, as specified by the user.
Seismic Wizard
Piping systems in earthquake-prone areas need to withstand seismic loads. Users can easily apply mapped accelerations to their models using the Static Seismic method in Aspect Pipe Stress with minimal inputs.
seconds.
Comprehensive Error Checking
Aspect Pipe Stress includes a comprehensive error checker that has been refined over many years. This checker checks the user's input and provides guidance to assist if anything unexpected or undefined is identified in the input.
EN1591 Flange Analysis
The EN-1591 standard is a calculation method for bolted, gasketed, circular flange joints that ensures structural integrity and leak tightness. It is a detailed and modern standard that provides greater accuracy than the Taylor Forge method, allowing for significant reduction in flange thicknesses and bolt sizes by up to 50% or more.
Expansion Joint Wizard
Adding an expansion joint to a piping analysis model can be complex. The user needs to define the joint, tie-bars, and ensure proper connections for flexibility. Aspect Pipe Stress's Expansion Joint Modeller automates this process by creating the model with correct flexibilities and connections, including tie bars.

More Key Features
Dynamic, Model Analysis
Calculating natural frequencies for a piping system is important to prevent vibration issues and fatigue failures. A low first natural frequency makes the pipe more susceptible to vibration, so it's recommended to have a frequency of at least 4 to 5 Hz. Additionally, a natural frequency close to that of reciprocating equipment can lead to resonance and failure. Aspect Pipe Stress offers modal analysis to calculate natural frequencies and mode shapes, making it easy to review and analyze the results.
Piping Analysis Integration with Forte 3DWorx (formerly CADWorx Plant Professional)
Creating a pipe stress analysis model is often tedious, involving manual reconstruction from isometrics. Smart 3D can digitally transfer data to Aspect Pipe Stress, simplifying the process and allowing for easy modifications. This saves time and effort, enables informed decisions, and reduces back and forth with the designer. The updated pipe route, support locations, and loadings can be easily transferred to the designer after the analysis.
Piping Analysis Integration with Smart 3D
Spring hangers are crucial to supporting a piping system when balancing vertical displacements. Aspect Pipe Stress allows users to select from thirty-eight hanger manufacturer catalogues to support their piping system and balance vertical displacements. Aspect Pipe Stress will then select the appropriate hanger based on the load and movement at the hanger location, as specified by the user.
Load Case Editor
Specifying all necessary load cases applicable to the design scenario is a critical part of the whole analysis process. Aspect Pipe Stress saves time by suggesting load cases to use, and provides features that make working with complex load cases simple and easy
Report Generation
After completing the analysis, it is often necessary to share the results with other stakeholders. Aspect Pipe Stress allows users to easily export the analysis results to popular formats such as MS Word or Excel.
Stress Isometrics
A stress isometric is a useful addition to any report, but manually annotating it can be time-consuming and prone to error. Using Isogen, an integral part of Aspect Pipe Stress, accurate isometric drawings can be easily and quickly produced with just a few clicks. Simply specify the desired information and Isogen does the rest, eliminating the potential for mistakes whilst saving time.
