MECHANICAL SLEEVE TYPE EXPANSION JOINT OF HEAT RECOVERY SYSTEM GENERATOR

摘要

PURPOSE: A mechanical sleeve type expansion joint of a heat recovery system generator is provided to maintain the air-tightness between a corrugated pipe and the sleeve using a packing member. CONSTITUTION: A mechanical sleeve type expansion joint of a heat recovery system generator comprises a corrugated pipe(110), a packing unit(120), and a fixing unit(130). The corrugated pipe is formed on the outer circumference of a sleeve(162). The corrugated pipe comprises first and second corrugated pipes(111,112). The first and second corrugated pipes are welded on the surface of a casing and the bottom of the packing unit. The packing unit keeps the air-tightness between the corrugated pipe and sleeve. The fixing unit fixes the packing unit. The packing unit comprises a pressing member(125). The pressing member is combined between a packing box and the sleeve.
