What GI Accessories? The Right Deals

Plumbing is possibly one of the most important systems installed in a residence or other structure. In order for the tubing to be installed correctly, plumbers use tubing to allow tubes to navigate and truss through gaps. While once a popular choice for general tubing, galvanized iron comes down to mostly fitting applications due to inherent problems with its performance over time.

According to the manufacturing procedures, galvanized pipes can be classified as hot dipped galvanized or electro toughened. The process of hot-dip galvanizing involves dipping carbon steel in molten zinc. In electro-galvanizing, however, the steel is quenched in an electrolyte solution containing zinc and the corrosion resistance coating is applied via electrolysis.

Galvanizing is the process of coating steel with zinc. Zinc coatings melt at 850 to 900 degrees Fahrenheit and evaporate at 1500 degrees Fahrenheit, whereas steel melts at 2600 degrees Fahrenheit during welding. When the weld pool freezes, the zinc covering vaporizes completely. Electrolyte galvanizing is a type of physical reaction in which the galvanized zinc layer attached to the pipe surface is thin and easy to rust, whereas hot dip galvanizing is a chemical reaction in which the galvanized zinc layer attached to the pipe surface has a thick protective layer form and is not easy to rust. The Zn coating’s sacrificial corrosion characteristics will be reduced after years of contact to air and a complex environment, and it will finally rust.

Galvanized steel pipes are employed when steel constructions are put into operation in an open environment, such as the production of HVAC equipment, agricultural greenhouses, and chain link fences, among other things, due to their lower strength and lower cost.

Galvanized steel has a lifespan of roughly forty years before it needs to be replaced. Galvanized pipes are often shortened by hard water in the residence. For optimal corrosion protection, galvanized steel tubing can be primed with most two-component epoxies or polysiloxane resins, or water-based acrylics for aesthetics.

ID Choices

Galvanized iron pipes are referred to as GI fittings. Pipe fittings, in general, are the components that connect individual pipes by joining them together. It can be used to compensate for changes in pipe diameter, bends and twists, and fluid transmission. Plugs, saddles, and elbows are some examples. Galvanized iron is a type of iron that has been zinc-coated. The coating prevents rust and mold on the iron device, mechanism, or substance, which is especially significant in water-exposed locations like plumbing.

Terminology and application

The terms galvanized iron and galvanized steel are interchangeable when it comes to pipes and pipe fittings. In this context, they both signify the same thing. Until the 1950s, this type of service pipe was a frequent component of plumbing systems. Despite the coating of galvanized zinc to the iron, it nonetheless rusted and has since been replaced in major part with copper tubing. However, galvanized iron or steel fittings are employed. These connections are typically used at the plumbing house’s “entrance point,” according to the experts at Inspectopedia.


Female fittings are galvanized iron or steel fittings that are turned to the thread at the tube’s end. When the pipe is much larger than the threaded pipe, the pipe is usually welded to the pipe rather than threaded in. Cast iron is commonly used for these accessories since the shape is softer and hence more pliable. When the metal is smooth enough, a simple saw bow can be used to cut it.

Because gi pipe fittings malaysia are frequently used with threaded pipe, a pipe joint compound should be applied to the thread before connecting pipes and fittings. Brushes or even a kitchen spatula can be used for this; however, an old one is no longer useful for cooking. Joint compound acts as a seal between two components, allowing them to endure high pressure while also preventing mold growth. If the pipe is going to be used in a shop where liquids other than water will be flowing through it on a regular basis, make sure the compound can handle it.
