1. large-sized methanol plant Intermediate Heat Exchanger imports and exports pipeline stress analysis method, and described Intermediate Heat Exchanger is set by bearingPut in support beam(

  • 1)

    Upper it is characterised in that:

    Described bearing is slidable structure, and described Intermediate Heat Exchanger passes through sliding support(

    2)

    Can be with respect to support beam(

    1)

    Produce certain displacement, by support beam(

    1)

    It is modeled to the hinged simply supported beam in two ends, calculate the firm of beamSpend, the Rigidity Calculation formula of its central sill is:

    k=48EI/l3, E is elastic modelling quantity, and I is material cross-section to neutral bending axisThe moment of inertia, l is beam length, finally, the rigidity of the beam calculating is brought in pipe stress analysis model.
