    Introduction - Pipeline Strength (Wall Thickness) : - External Pressure

    Uploaded by

    The document discusses pipeline strength and wall thickness. It notes that if a buckle forms in a pipeline, it can propagate along the pipeline. While buckle propagation pressure is usually lower than collapse pressure, it is more economical to design for collapse pressure. However, thicker pipe joints or buckle arrestors need to be installed at regular intervals to isolate any buckled sections.

    Introduction – Pipeline Strength (Wall Thickness)

    • External Pressure
    – If a buckle is formed it may propagate
    along the pipeline
    – Usually buckle propagation pressure
    Ppr < collapse pressure Pc
    – Therefore it is more economical to design
    a pipe on collapse pressure than propagation pressure,
    But There will be a need to fit thicker pipe joints or
    buckle arrestors at regular intervals to isolate any
    buckled sections
