Socket union assembly process for tubular pipes, involves arranging expanded ring to end of tube, inserting accessory into expanded end of tube, and then dragging ring towards end of tube where accessory is inserted

摘要

The method involves expanding the internal diameter of a ring to be slightly greater than the external diameter of a tube. The expanded ring is then placed at the tip of the tube, such that the ring is coupled to the end of the tube. The end of the tube is then expanded to have an internal diameter slightly greater than the maximum external diameter of the coupling area of an accessory. The accessory is then inserted into the expanded end of the tube. The ring is then dragged towards the end of the tube.
