    High-Temperature Industrial Gas Duct - Germany

    Project Overview

    Arcus Engineering performed structural and connection analysis for an industrial gas duct in Germany designed to operate at a temperature of 220°C. The analysis focused on structural resistance, temperature-dependent material behaviour, thermal expansion and the functional movement of separate duct sections.


    Project Challenge

    High operating temperatures can produce significant thermal expansion and deformation within industrial duct systems.

    If these movements are not represented correctly in the numerical model, they can generate unrealistic internal forces or interfere with the required functional behaviour of the system.

    The duct was therefore divided into sections separated by expansion provisions, with each section requiring individual numerical assessment.


    Numerical Modelling Approach

    Arcus Engineering created separate structural models for the expansion-separated duct sections.

    The analysis considered:

    • operating temperature of 220°C
    • behaviour of 16Mo3 / 1.5415 material
    • temperature-dependent material properties
    • thermal expansion and restraint
    • deformation in the global X and Y directions
    • structural resistance under operating loads
    • behaviour of the relevant steel connections

    Modelling the sections separately enabled thermal movements and structural responses to be assessed according to their specific support and expansion conditions.


    Deformation and Functional Verification

    Temperature-related deformations were evaluated in two principal directions.

    This verification was important not only for structural resistance but also for confirming that the gas duct could accommodate the required movement under operating conditions.
