"Hot-dip galvanizing" and "pre-galvanizing" are both galvanizing treatment methods for metal surface corrosion protection, but their processes and applications are different: 1. Hot-dip galvanizing:Process: The steel is immersed in molten zinc liquid (usually at a temperature of about 450°C) to reac

Pre-galvanized steel pipe is one of the most common and popular types of pipe today, made of solid steel with an additional zinc coating. The role of the zinc coating is to prevent the steel pipe from rusting and corroding. Since the pre-galvanized steel pipe does not rust or corrode, the pipe will

In recent years, due to the increasing need for pipe welding in various industries, There has been an increase in work opportunities for pipe welders. Since welding is a complex job, pipe welding needs professional workers.However, in industries, there is a reasonably large margin for errors to occur.

Pipe welding is a method for connecting two pipes together. Some make a distinction between pipe welding and pipeline welding, with pipe welding relating to metal pipes at plants and refineries and pipeline welding referring to those used to transport gas, water, oil and other liquids over many miles.
