API 5L pipes are welded together on pipe rack. A but joint weld is resting on the structure beam. The pipe is of 20" Diameter for Fuel gas service. Technically is it some thing that should be avoided at any cost. Does it affect on the integrity of the weld joint. The Inspecors says, if there is Leakage, how it will be detected. Is it really a concern from technical point of view. Please advise. Thanks,
