Hot Dipped Galvanized Steel Pipe: 5 Different Methods of GALVANIZING

April 26, 2021

Hot Dipped galvanized steel pipe and the 5 methods to Make it

A hot dipped galvanized Steel Pipe undergoes various procedures to attain corrosion-free and strengthened status. Metal pipes are essential for everyday construction and architects have favored galvanized pipes for a long time. The galvanization procedure dates back to the early centuries however the recent advancements have made it accessible for industrialists.

The industrial piping sector was in a dilemma when their pipes kept corroding however the galvanization procedure fixed everything. The zinc coating on stainless steel and other metals improves their standing moreover the pipe becomes a reliable investment. Pipe companies have begun to choose the pre-galvanization process per its promising results.

Furthermore, there is no one correct way of performing the galvanization process. You may change the peripherals according to the coating range and strength needed. You can perform this procedure at home as well with the right products.

Larger objects such as steel pipes undergo the hot-dipped galvanization process for more efficiency and higher success rate. Some components are better suited for a specific galvanization method due to their size and function.

Industrial galvanization is possible in more than one metal moreover it pronounces their natural qualities such as durability and strength. This process does not remove or impact the functional properties of the galvanized products in any way.

Reasons for Choosing a Hot-Dipped Galvanized Steel Pipe Over Others

The Hot dipped galvanized Steel pipe has many rustic benefits. Steel pipes that are not subjected to galvanization have a higher probability of facing corrosion. Corrosion and debris accumulation does not occur overnight; the process may take years. Unfortunately, while these pipes wither away the world above ground level may progress a lot.

The removal of damaged pipes after a decade can cause unwanted distress to the residents and commercial places in that area. For this reason, the galvanized pipes pose a better investment. Galvanization of pipes takes hours or days tops however the results are solid. The galvanization will leave a pipe with a rugged surface however it shows no changes when seen from the naked eye.

Importance

Moreover, many industries and businesses depend upon galvanized steel pipes including architecture railway, and interior designing. The absence of these steel pies hinders the performance of larger projects. Projects are made from smaller components like steel pipes thus their failure to function correctly can cause larger projects to come to a halt.

You can place galvanized steel pipes underwater and in any soil. Sometimes the environment around the pipe plays a larger part in its withering compared to the material used. Even high-quality steel can get ruined when placed in a hostile environment. The zinc coating fights the threats of rust.

It is possible to remove a steel pipe from a place and begin to galvanize it but that takes a lot of time, effort, and money. The more logical course of action is to pre-galvanize all steel pipes instead of uprooting them from working since there is no replacement for these pipes while they galvanize.

Galvanization machinery is massive hence large-sized pipes can easily fit inside the hot-dipped tubs. Manufacturers divide the pipe into smaller portions if they cover a larger distance.

The Five Popular Methods to Perform Galvanization

A Hot dipped galvanized Steel pipe comes from a much-acclaimed method. As the name suggests, hot-dipped galvanization includes a pool of zinc coating where the pipe dunks in a zinc vat. The process begins with a chemical stripping the steel surface of all impurities.

The canvas should always remain clean for the galvanization to take full effect. You can not cover the long steel pipe with singular coating hence the dipping takes less time and covers more ground. This method is the most common among industries since they must produce many pipes in a limited time.

Gavanealing

The second most popular galvanization method is gavanealing. Galvnealing is an amalgamation of hot-dipped galvanization and annealing. This method particularly suits the clients who want an extra layer of protection and matte effect. Annealing creates a visible matte appearance on the pipe which makes it easier to paint.

Clients who will likely display the pipes in interior designing choose galvnealing.

Mill-Galvanizing

Furthermore, Mill-galvanizing or pre-galvanization involves the zinc coating of pre-shaped, materials such as steel coils. Although this method suits some specific shapes, it is not possible for massive structures. The zinc coating might not reach every part of the product.

Moreover, the inside of the pre-galvanized material will not have the zinc coating.

Electro-galvanizing

Electro-galvanizing is an unconventional method of providing zinc coating to a substance. This method does not incorporate a zinc vat but uses the electrolysis method to coat a product.

Although this method is highly efficient for products with a smaller size, it is not as nearly good with large structures such as pipes. The coating does not appear as smooth as that of a hot dipped Galvanized Steel Pipe.

Manufacturers do not currently practice this method largely however it ensures that the steel has a higher quality surface compared to previous ways of galvanization.

Take Away

There is not one approach when it comes to the manufacture of a hot dipped galvanized steel pipe. Hot-dipped galvanization reduces the time pressure compared to other methods moreover it guarantees a standard coating on the entire product. The ways of galvanization have evolved but they get better with each invention. Some methods appear better than others according to the object used. Wen comes to steel pipes, the hot-dipped galvanization method takes the win. This method ensures that the pipe will not damage or become disposable even after long term use. The integrity of a steel pipe does not entirely depend upon galvanization hence high-quality steel and raw materials should have priority.

Moreover, tension leveled steel will promote functional duties. If seen from the bigger perspective, the cost of galvanization is minute. Removal and fixing of old pipes will cost a fortune if they aren't galvanized so think of this as an investment for the future.
