APPARATUS AND METHOD FOR SEALING A VENTILATION CHANNEL OF A PIPE

摘要

A method of sealing a ventilation channel for a pipe is disclosed. The method may include inserting a sealing insert into a ventilation hole of the ventilation channel, applying a vibrational energy to a region between the sealing insert and the ventilation channel, deactivating the vibrational energy once the sealing insert and the ventilation channel are welded together at the region, and forming a flush interface between the sealing insert and the ventilation channel at the ventilation hole.
