Investigating the types of building pipes
Each building has unique plumbing depending on its use. The correct implementation of plumbing is one of the most important issues in construction, if it is not up to standard, water may leak and cause irreparable damage to the structure and building.
Different pipes are used in plumbing, each of which has different materials and functions. In general, the pipes that are installed to transport water in the building are divided into galvanized, cast iron, polypropylene, PVC, five-layer, polyethylene and other types of pipes.
Types of building pipes based on materials
Galvanized pipe
Galvanized pipes are divided into two types of steel and iron pipes. They are not resistant to acidic substances. They are made of mild steel and are often used as sewer pipes for various places in the structure. In contrast, galvanized iron pipes are light in weight and gray in color.
Galvanized pipes have high pressure resistance, but they suffer from corrosion and sedimentation, so they are rarely used for piping in today's buildings. These pipes are dangerous to human health due to the thick smoke that is created during welding. throws and pollutes the environment, they cannot be connected to each other through welding.
Polypropylene pipe
The weight of these pipes is very light. It is resistant to green pipe, which has made its use popular in construction. These pipes have very high strength and are not damaged by acidic and mineral substances. In addition, the resistance of these pipes has made them resistant to impact and made them an ideal pipe in the construction industry. It should be noted that polypropylene pipe is also known as single layer pipe and PP pipe in the market.
Cast iron pipe
These pipes are made of cast iron and depending on the place of use, they are made in shapes, dimensions, connections and all kinds of alloys. The cast iron pipe has the necessary resistance against the pressures that are applied to it and is less eroded than the iron pipes. This pipe is opened by the air compression device and its clogging is removed. The biggest disadvantage of these pipes is their corrosion due to the presence of chemicals in the sewage, which is inevitable.
Cast iron pipe is cheaper than metal pipe, but it is slower to install. Chemicals have a negative effect on these pipes and cause them to rust.
Cast iron pipes are heavy and difficult to connect to other joints and fittings. These pipes, like galvanized pipes, are rarely used today due to irreparable defects.
PVC
PVC pipe is one of the polymer pipes that is widely used in the construction industry.
The flexibility of these pipes is very high and does not crack or break.
PVC pipe has very little weight and is easy and fast to install. This type of installation pipe is available in gray, white and yellow colors and its price is cheaper than other pipes.
Plica pipe, which is sold in the market today, is one of the PVC pipes that has high mechanical properties and meets the needs of building plumbing.
These pipes are resistant to acid and alkaline activities and chemicals do not have an adverse effect on them.
The Plica pipe does not change the color and smell of the water, and due to its polished surface, the rate of sedimentation and clogging is very low.
Five layer pipe
The outer and inner layers of the five-layer pipe are made of a type of polymer called polyethylene.
These two polymer layers are connected to the aluminum layer, which is the middle layer, by two adhesive layers.
The aluminum layer of these pipes increases the pressure resistance of the pipe, so it will not be damaged in the event of an impact.
The five-layer pipe does not suffer from rust and corrosion, and its strength is high against acidic and alkaline substances.
This type of pipe is used in various places to transfer hot or cold water, including underfloor heating systems and building air conditioning systems.
These pipes have a good appearance and are used as built-in or facing.
Fungi and bacteria do not grow in these pipes, so they can be easily used in the building.
CPVC tube or polyvinyl chloride chloride
These pipes are made of cream and white plastic and are used in high temperature and pressure due to their high hardness and low price.
These pipes can be used to distribute hot and cold water in the building. PVC pipes can be easily cut with a pipe or an iron.
Polyethylene pipe
This pipe is known as PE in the market and is made of a type of thermoplastic called polyethylene.
Great flexibility is one of the unique features of these pipes, which allows them to be used in different places.
Polyethylene pipes are made with different densities depending on the type of application.
They are a good alternative to other tubes and are also affordable.
The hydraulic properties of this pipe and its low maintenance and repair costs have made polyethylene pipe a popular pipe among manufacturers. Polyethylene pipe has a high impact resistance and does not get damaged or cracked.
Chrome -coated rice
Chrome-plated brass pipes have a shiny chrome surface over one inch in diameter and are used in exposed pipelines such as sewer siphons. These pipes can be easily cut with a chainsaw and used in various applications.
Copper pipe
Copper pipes have a red and matte appearance and are available in two types, hard and flexible. Hard copper pipes are commonly used in drinking water and domestic sewage piping.
Flexible pipes are also used in the inlet water pipe of refrigerator and dishwasher. The thickness of hard copper pipes is indicated by the letters K, L and M.
