There are different types of electrical Pipe or Conduit, but they
are generally divided into two main categories according to the
standard material used in them.
1- Metal electrical Pipe or metal conduit.
2- Non-metallic electric pipe or non-metallic conduit.
What is an electrical Pipe or Conduit?
Electric pipe or Conduit is one of the methods used to
create power transmission projects in residential and
non-residential buildings, including office, commercial,
factory and industrial buildings, etc. Due to their use
in various locations, electrical Pipe or Conduits are
widely used in the production cycle of their products.
In principle, and according to the general standard,
these candidacies are classified according to two main
categories as metal or metal conduit and non-metallic
electric tube or non-metallic conduit.
Why is it important to use Electric pipe or Conduit?
One of the most important steps in any project is to
create a set of electrical systems. To do this, you can
use new and new methods that have many advantages, such
as Electric pipe or Conduit. Using a conduit to pass
wires or cables can bring us security, quality, cost and
time savings, speed, and many other benefits.
On what basis are electric pipe or Conduits classified:
Conduits or electric pipe have two general categories
based on the materials used in them:
1- Metal electric pipe or metal conduit:
Electric pipes or metal conduits are often made of
galvanized steel, stainless steel or aluminum. Other
metals are generally not used in the manufacture of
electrical pipes or metal conduits.
2- Non-metallic electric pipe with non-metallic
Non-metallic (plastic) electric pipe or Conduits are used
in areas where metal use is difficult (such as a hospital
MRI room) or in places where there is a risk of direct
contact with water. Because in contact with water,
non-metallic conduit are resistant to water due to the
type of material and do not suffer from rot or rust.
The important point of both models is that both of them
may be rigid or flexible.
Metal electric pipe or metal conduit:
Electric pipes or metal conduits are often made of
galvanized steel, stainless steel or aluminum. Other
metals are not commonly used in the manufacture of
conduit. They can protect people from unwanted contact
with the current in the wires, as well as the wires and
insulation of the wires against environmental damage.
conduit creates a fully advanced infrastructure for
wiring. It used a variety of locations, including
non-construction sites and hotels, office buildings,
commercial and commercial buildings, industries and
factories, and underground facilities. In principle, metal
conduit are rarely used in building or apartment wires or
The principle of passing cables or wires through or metal
electrical Pipe or Conduit is done according to a certain
number and size according to a certain standard. This
standard between wire and pipe is very important in terms
of size. Metal conduit electrical Pipeline is produced by
NiruTavan Abtin Company during the production process in
accordance with special standards from PG11 diameter to
1- Standard UL 7971 standard in terms of protection and
2- ANSI C80.3 Standard manufacturing process.
3- ASTM A123 Standard Pipe galvanizing method.
Different types of metal electrical pipes or metal
conduits based on strength standard:
1- Hard metal or metal conduit Pipe (RMC).
2- Medium metal electrical pipe or medium metal conduit
3- Flexible metal electric pipe or conduit (FMC).
Different types of non-metallic electrical pipes or
non-metallic conduit based on strength standard:
1- Non-metallic electrical pipe or hard and non-metallic
2- Non-metallic electrical pipe or non-metallic conduit
Types of metal electrical pipe or conduits steel:
1- Hot metal galvanized electrical pipe or conduit steel
(Hot Galvanized Pipe).
2- Cold metal galvanized electrical pipe or conduit
steel (Cold Galvanized Pipe)
3- Metal electrical pipe or conduit colored steel
4- Explosive seamless metal galvanized steel electrical

Types of non-metallic electrical pipes or non-metallic
1. Non-metallic electrical pipe or conduit pvc , which
has three models
■ Hot bending electrical pipe.
■ cold bending electrical pipe.
■ fireproof electrical pipe.
2. Polyamide electrical pipe.
3. Flexible electrical pipe.
Tight or strong electrical pipe or conduit (RMC):
This type of conduits has tubes with thick, bandaged
walls. They are usually made of insulated steel,
stainless steel or aluminum. This type of metal conduit
is connected to other electrical pipes by special
connections. The solid metal conduit protects the wires
and cables against environmental influences and hazards.
Rami metal electrical pipe can be customized according
to the needs and proper consultation with Nirutvan
Company regarding the ongoing project. They can be made
with thicker walls to prevent and protect against
electromagnetic disturbances in the wiring system.
Covering this conduit or metal electrical pipes with a
layer of PVC or galvanized, bronze and. Can also make
them resistant to decay and rust. Tubes
Medium electrical Pipe or conduit (IMC):
These types of conduits are the lightest and cheapest of
the current conduits. To prevent water from entering
them, they are boiled with special solvents. One of its
major advantages over other metal electrical cables is
that they are quick to install and easy to connect to
each other. For proper bending and shaping of plastic
Conduits, it can be used with the heat provided by a
special tool. For special occasions where we need
stronger hard drives, their walls can be thickened so
that they become harder to connect.
flexible electrical Pipe or conduit (FMC):
Flexible electrical pipes are thin-walled plastic pipes
that give them high flexibility. They can be easily
shaped and used on high-winding routes. This type of
conduit is very easy to install because it can be cut
and re-welded when it encounters obstacles.
Hot metal galvanized electrical pipe or conduit steel
In this model, metal electrical pipes that use deep
plating are mostly used in areas with humidity and open
environments where there is a possibility of contact
with rainwater. This model of pipe is resistant to
crushing and rust and environmental factors.
The first and most important goal of hot-dip hot
galvanizing is to protect the structure against
corrosion, and the durability and durability of
galvanized depends practically on the thickness of the
layer on the protector. In the production stage, the
thicker the protective layer, the longer it will last
and the longer it will last for the product.
The production of hot galvanized pipes according to the
following two methods and standards:
1- Sherardizing method.
2- Hot Dip Galvanized immersion method.
Cold metal galvanized electrical pipe or conduit steel
This model of metal electrical pipe or conduit is one of
the most common types that is used more than other
The production of cold galvanized pipes is according to
the following three methods and standards:
1. Zinc Plating or Electro Galvanizing.
2. Mechanical Plating method.
3- Galvanized method by zinc-impregnated paints by spray
or brush (Zinc Rich Coating).
Metal electrical pipe or conduit colored steel (black).
As the name implies, metal electrical pipe or conduit
are used to prevent rusting in this model. They can be
used indoors, in concrete. This pipe model should not be
used in environments with high crushing properties and
in places that are in direct contact with the ground.
This model metal electrical pipe or conduits has two
■ Reasonable price compared to hot galvanized pipes.
■ Convenient and convenient connections are available.
Explosive seamless metal galvanized steel electrical pipe
Explosion-proof electrical pipes are one of the types of
pipes used in sensitive industries and explosive
environments, and the price of this product is higher
than other types of metal electric pipes, and it has a
heavier weight than sealed pipes.
Flexible metal electrical pipe or conduit or flexible
This model of pipe can be used in cases where the
electric steel pipe passes through the expansion joint
of the building or to connect the electricity to motors
or devices that vibrate during operation. They show good
flexibility during work and plastic or similar materials
are used to create flexibility inside these pipes during
the production stage.
UPVC electrical pipe:
It is produced in two types of cold and hot bending.
Upvc pipes have a high strength and the cold bend type
is bent without the need for heat and using a special
spring, and is much stronger than the hot bend type.
PVC electrical pipe:
This electrical Pipe model, which is made of plastic and
other composite materials (softeners and lubricants),
weighs less than its metal counterparts. Insulation and
cheaperness are the advantages of this pipe compared to
metal pipe, PVC electrical pipe is non-flammable and has
many applications in the construction industry.
Polyamide electrical pipe:
This type of pipe is made of soft plastic. These types
of pipes are less expensive and more flexible than other
pipes. They are currently used in small and light
flexible electrical pipe:
This type of pipe is produced in three models: PVC,
polyamide and metal.
■ PVC is used to pass electrical wires on the walls of
the structure. These pipes bend at any angle and their
components are PVC and non-flammable.
■ Polyamide is much cheaper than PVC. It bends at
different angles but has little strength.
■ The metal type is used for passing electrical wires in
industrial panels and exterior walls. The material of
these pipes is made of PVC coating with wire to increase
the strength of the pipe and its strength.
Polyethylene electrical pipe:
In terms of strength, these non-metallic electrical
pipes are placed between the flexible and pvc pipes,
which are softer than pvc pipes and stronger than
flexible pipes. Can't use.
