Static and thermal assessment
Evaluate sustained loads, pressure and thermal expansion against the applicable piping criteria. Review movements and flexibility across normal and defined operating cases.
Reliable. Compliant. Engineered for Tough Conditions.
Piping Stress Analysis Services
Check how piping responds to operating, thermal and external loads before those loads become installation or reliability problems. Teckniv evaluates piping flexibility, stresses, movements, supports and equipment connections. The analysis supports layout decisions and provides coordinated inputs to piping, mechanical and structural teams.
EPC piping teams, equipment suppliers and operators that need to verify flexibility, support loads and equipment-nozzle interfaces for new piping or plant modifications.
01 / Engineering capabilities
The scope is agreed around the decisions, interfaces and engineering outputs your team needs. These work areas can be combined into a defined package.
Evaluate sustained loads, pressure and thermal expansion against the applicable piping criteria. Review movements and flexibility across normal and defined operating cases.
Assess nozzle loads, restraints, guides, anchors and support arrangements. Coordinate recommended changes with the available structure, equipment limits and installation requirements.
Evaluate seismic, transient, fatigue and vibration-related conditions where required. Establish the excitation, load cases and available data before selecting the analysis approach.
Compare routing or support alternatives and document the governing cases. Provide actionable results for drawings, support design and equipment coordination.
02 / Your engineering package
The deliverable list is agreed at the start. Each issue identifies its purpose, revision and outstanding inputs for the next project stage.
03 / How we work
We establish the design basis first, then develop and review the package with your project team.
Validate line information, boundary conditions and load cases.
Build the analysis model and check its behavior.
Review stresses, movements and interface loads.
Coordinate changes and issue the final analysis package.
04 / The technical context
The equipment duty, project location and client standards determine the methods, platforms and acceptance criteria.
Oil and gas, petrochemical, chemical, power and utility systems, including steam, process piping, equipment-connected lines and brownfield tie-ins.
CAESAR II supports piping stress modeling, with analysis inputs coordinated against piping isometrics, support details and equipment data. Where another platform is required, compatibility and model handover are agreed before the study.
Relevant ASME B31 code requirements, material specifications and equipment/vendor load limits are selected for the system. Additional API or project criteria may govern equipment interfaces and particular assessments. The applicable code edition and load combinations are stated in the report.
