GI Pipes are a sort of metal pipes especially made by compound of galvanized iron metal. These kinds of pipes prove really helpful; they transport several vital resources such as water, oil and gas and several other thing GI pipes own their high strengths due to that do not face destruction or damage by being dusty due to long intervals. Due to their durability, they are widely used in many applications. But the question is, how gi pipe are manufactured? And what’s that make them so hard and with a long duration?
From Metal to Pipe
GI pipes are manufactured from a straight, long piece of metal. That metal is put through a massive machine that molds it into a cylindrical pipe. Shaping it properly is the most critical step to getting the pipe to work as intended. Once shaped, the pipe is then coated, a process known as galvanization. Galvanization: The gi square pipe are dipped into hot liquid zinc in a galvanization process. This hot-solution of zinc forms a barrier around the metal. This layer is very much important as it protects the metal from rust and environmental damage.
After covering the pipe completely with zinc, it is slowly cooled so that it will harden accordingly. They cool it and then check whether everything is okay or not. If the pipe passes through the checking test, it is then cut to the exact length needed for use in various places\
Why Don't They Rust?
This is why GI pipes are very tough and durable — the galvanization process. Zinc is a fantastic material that acts like a shield from corrosion. The zinc coating interacts with air or water first, thus preventing the steel under the coating from rusting.
Why GI Pipes Last a Long Time?
The protective zinc coating over gi pipe sch 40 is extremely durable and does not need a replacement for dozens of years, so they work great for myriad applications. Additionally, they are applied in dozens of industries, namely in plumbing, construction, agriculture, and several others. The layer of zinc will eventually be worn down also, but in many cases this will take thousands of years --- even tens of thousands of years in some applications --- depending upon how the steel pipe is used and to what they are exposed.
