GI Conduit

Galvanized Iron Conduits are rigid and flexible conduits used for various commercial and household applications. These GI Conduits have a long life expectancy of about 50-70 years. However, these conduits' life span depends on air and water contaminants. GI pipes' life span also varies on the thickness of the zinc coating applied on the pipe.

Size in MM Ext. Dia (mm) Tolerance in Ext. Dia Thickness
20 20 -0.3 1.4 to 1.8
25 25 -0.4 1.4 to 1.8
32 32 -0.4 1.4 to 1.8
40 40 -0.4 1.6 to 2.2
50 50 -0.5 1.6 to 2.2

In the installation of electrical equipment, conduit pipes are used for the protection of electrical cables. Mainly three types of electrical pipes are used in electrical construction. GI, Flexible Metal and PVC are the three types of electrical conduit pipes. For the installation of PVC pipes, copper and glue is mainly used. However, for installing the GI Conduit Pipes, a GI vendor machine and wrench are used. 

GI Conduit Introduction

The term GI in GI conduit pipes stands for Galvanized Iron. Modern production units make these GI conduits from top-notch quality mild steel. GI conduits replaced all the other materials used for electrical pipes to prevent them from rusting from the outside and inside.

What Are the GI Conduit Types?
GI (Galvanized Iron) electrical pipes are mainly classified into three types depending on their weight and inner diameter. The more the inner diameter thickness will be, the more the pipe will be durable and sustainable. According to the rule of IS 1239, each GI pipe will have a colour strip around the circumference to identify the class.


What Are the GI Conduit Uses?

Galvanized Iron conduits are used for both households as well as industrial purposes. However, the primary uses of GI pipes are:

    • Transportation of Water and Sewage
    • Structural purposes
    • Electric Poles
    • Transmission of Oil and Gas
    • Engineering purposes
    • Automotive purposes
    • Compression of Air Lines
    • Fire Fighting Equipment
    • Air Ducts


    Features of GI Conduit

    Galvanized iron pipes and their attachments offer many high durability and flexibility features. However, the main features of GI pipes include the following:

    Protection Against Fire

    Galvanized iron pipes protect against fire because they are flame resistant. These conduits are entirely halogen-free and do not produce any toxicity or smoke. In addition, GI pipes have a very limiting oxygen index, which means they do not catch fire or smoke quickly.

    Mechanical Strength

    Galvanized iron provides a higher tendency to pain, which directly reduces the risk of rusting. Therefore, these GI pipes are ideally the perfect choice for water-supplying pipelines as they are more prone to rusting. Moreover, GI conduits can also easily withstand all the other physical forces.

    Highly Flexible

    Galvanized iron also comes with a high degree of elasticity, decreasing the chances of breakage. This also ensures that the transfer of water, wire or cables will be smooth. However, these pipes have a stronghold in the market because of their stronghold and flexibility.
