Pipe Stress Analysis
Pipe stress analysis is concerned with the prevention of overstressing pipes, skids, vessels, flanges, bolting, gaskets, valves, relief devices, fittings, hangers and supports.
Typical Problem Areas
- Pipe hanger/support failure
- Equipment support structure failure
- Verification of unfired pressure vessel design
- Blast resistance
- Pressure surge damage
Our Expertise
SVT offers a complete range of piping, skid, pressure vessel and tank storage engineering services. We specialise in mechanical detail design of piping, skids, pressure vessels, shell and tube heat exchangers, including the supply of detail drawings for fabrication.
Pipe Stress Analysis
SVT offers pipe stress capability for onshore and offshore installations complying with international codes (e.g. ASME B31.3, ASME B31.4, ASME B31.8, DNV2000), services include:
- Static design (operating, wind, seismic analyses and fatigue evaluation)
- Dynamic design (modal time history and harmonic analyses)
- Blast resistance design (using state-of the-art tools to design piping for blast resistance)
- SVT can also assist clients in carrying out fire and explosion studies and quantitative risk analysis, which are pre-requisites for a comprehensive blast design
- Assessment of acoustically induced vibration (AIV) effects and fatigue life evaluation of piping, to internationally acceptable practices
Software to be chosen in consultation with clients (options include Caesar II, Autopipe, Triflex).
Pipe Support Engineering
SVT offers a complete pipe support design service. SVT can develop pipe support standards that address clients' needs, using the clients' basis of design, early in the project. SVT will assist clients in selecting the most economical pipe support and spring hanger systems and advise on component material usage to minimise weight. SVT can also provide factory supervision during fabrication and installation.
