What Is Hot Dipped Galvanized Steel Pipe?
Pipes are often given various kinds of surface treatments. Usually, these treatments are based on several factors. Some of which include the environmental condition, the temperature of the application, in addition to the occurrence of stresses or pressure levels. This being said, one of the most efficient surface treatments conducted on pipes is to galvanize them. Basically an ASTM A53 galvanized pipe is coated with a layer of zinc, which not only improves its corrosion resistance but also enhances several other properties of the material.

What Is The Difference Between Galvanized And Hot Dipped Galvanized Pipe ?
Although both these terms are interchangeably used to describe an ASTM A106 galvanized pipe, Galvanization is a process that could be performed at either a cool or hot temperature. Typically, a hot-dip process is preferred by many manufacturers as heat improves the fluidity of the liquid zinc and makes it uniform. Hence a uniformly coated Galvanized Mild Steel Pipe is achievable via this process.
Is Hot Dip Galvanized Seamless Steel Pipe Rust Proof?
While most high-end steel grades have chemistry that delays the onset of rusting, this is a common feature of low-cost grades. However, this is a problem that could be modified with galvanization. Though galvanization forms a thick layer on the surface of the Carbon Steel Seamless Galvanized Pipe, they are not rust proof. Yet, with proper diligence, it is possible to delay rusting, so long as there are no scratches on the surface of the Gi Coated Pipe.
How Long Will Hot Dip Seamless Galvanized Pipe Last?
The performance of a Stainless Steel Galvanized Pipe could last for a long time if used with care and with timely servicing. Rough handling the pipes could cause them damage, thereby making corrosion inevitable.
| Years | Conditions |

| 13 | heavy industrial use |
| 50 | ocean |
| 104 | suburbs |
| 30 | City area |
What Are The Advantages And Disadvantages Of Galvanising?
The main advantage of Hot Dipped Galvanized Steel Pipe is that it increases the corrosion resistance, thus improving, not only the quality but also the appearance and performance of the product. The disadvantage of using this coating on a schedule 40 galvanized pipe is that it can get chipped or cracked, leaving the surface exposed, making it vulnerable to decay.
