GALVANIZING (Blowing System)

This blowing system is an adapted Japanese technology and one of the newest methods of galvanization. The steps are as follows:

Metal Preparation

The pipes go through the process of pickling, degreasing, and fluxing in preparation for the dipping process.

Pre-dipping Phase

Dipping

The pipes are immersed into a tank of molten zinc.

Auto Pick-up Device

Also called as the post-dipping procedure.

Air Wipe System

This process ensures the zinc coating to be evenly spread on each pipes’ surfaces.

Steam Blowing System
