Learning Objectives

The course supports the students to learn how to calculate design and control oil and gas implants' components


Course Structure

he lessons will be held three-weekly in the second half of the second year, also the calculation and project exercises will be carried out.



Detailed Course Content

Additions to the knowledge of the state of stress and strain.
• ideal stresses for brittle and ductile materials,
• Failure under constant load.
• Creep at high temperature, creep curves, the design of components that work at high temperature: use of the relations of Larson - Miller,
• Curves of unstable crack propagation, safety coefficients for components working at high temperature.
• Failures under cyclic loading (fatigue) in the presence of high temperature and aggressive ambient.
• Nucleation and propagation of the crack, up to fracture, estimate the life of a component, systems of experimental controls in situ.
• Design of components for the chemical industry and environmental requirements.

Piping and Instrumentation Diagram

Lines for the transport of fluids (Dangerous and non)
• piping under pressure,
• connections with flanges,
• connections by welding,
• valves, choice of valves and safety systems.
• Using traditional methods and computer codes dedicated,for the design of lines
• Calculation of natural frequencies of vibration of piping lines or parts of piping lines.
• Issues for the control of the state of safety of operating lines, control systems and non-destructive analysis.
• Assessments on the recycles of the line parts and complete replacement.


pressure vessels and chemical reactors,
• Behavior membrane of axial symmetric shells.
• Instability of the cylinders subjected to external pressure and funds flat and curved.
• Edge effects (cylindrical shell): compatibility of deformations, additional stresses.
• Containers and thick parts: general theory, states of stress due to pressure and temperature, constructive solutions for high pressure (control of the load on the bolts).
• Containers Project in accordance with Italian legislation, European Directive 97/23 PED Pressure •Equipment, harmonized standard EN 13445 (calculations using traditional logic and FEM codes with comparison of the results, solid models).
• Acceptance of components and equipment checks on materials and components for chemical and petrochemical industrial.
