摘要：Apparatus for blast-cleaning the interior surface of a pipe includes a mainhousing that travels the length of the pipe, and rotatably supports a blast nozzle. Anozzle support shaft carried by the housing rotates freely, reactively to air carryingabrasive media and forced through the nozzle under high pressure. Since the air isdirected through a non- rotating conduit to the shaft, a gasket is interposed between therotating and non-rotating components. To prevent the abrasive media from penetratingthe shaft support bearings of the housing with obviously destructive effects, a gap ismaintained between the housing and a junction housing in which the non-rotating conduitis mounted. Leakage that does occur past the gasket is dispersed to the ambientatmosphere through the gap, before it can impinge upon the bearings. The non- rotatingconduit is threadedly advanceable within the junction housing, so as to correspondingly,selectively adjust the extent to which the gasket is compressed. In each position to whichthe conduit is selectively adjusted, it can be locked, to preserve the adjusted compressionof the gasket.
