Способ замены патрубка в сосуде под давлением заключается в следующем. Удаляют патрубок и подготавливают кромки в первоначальном сварном шве. Освобожденное отверстие для патрубка частично рассверливают изнутри сосуда. Помещают втулку с фаской под сварку в рассверленную часть отверстия для патрубка и сменное сопло во втулку с фаской под сварку. Втулку и сменное сопло приваривают по месту на внутренней стороне стенки сосуда.The way to replace the nozzle in a pressure vessel is as follows. Remove the nozzle and prepare the edges in the original weld. Released hole for the nozzle is partially reamed from the inside of the vessel. Place the sleeve with the chamfer for welding in the bore part of the hole for the nozzle and the replaceable nozzle in the sleeve with the chamfer for welding. The sleeve and the replaceable nozzle are welded in place on the inside of the vessel wall.
