Welding directly onto a pipe carrying pressurized hydrocarbons introduces extreme thermal risks. If the localized heat from the welding arc reduces the thickness of the pipe wall too drastically before the weld pool solidifies, the inner pressure will burst through the material, resulting in catastrophic failure. The standard mandates highly precise calculations regarding fluid flow rates, fluid heat capacity, and minimum wall thickness tolerances to safely dissipate the arc heat. 2. Hydrogen-Induced Cracking (HIC) Risk

Why is this important? In the engineering and procurement world, a project might specify adherence to a particular "latest version" of a Shell DEP. The question of whether to use version 46 (or the latest version) is a critical decision affecting design, material procurement, and construction. For instance, a document like "List Shell Dep & Mesc Spe" notes that the relevant and applicable Shell DEP standards are the latest version, with "latest version (currently 39)" at the time of that document's creation. This indicates that version "46" would be a more recent update, embodying the latest engineering knowledge.
