Polyethylene Pipe | A Complete Guide to Selection, Application, Types, and Purchase
The polyethylene pipe is one of the most widely used pieces of fluid-transfer equipment in civil, industrial, agricultural, and urban projects. Thanks to its high strength, long service life, light weight, and easy installation, it has now replaced many metal, concrete, and PVC pipes. These pipes are used in the transfer of drinking water, water supply networks, sewage, drainage, effluent transfer, the oil and gas industry, mining, road construction, and many infrastructure projects.
With advances in polymer manufacturing technology, polyethylene pipes are designed and produced in various models, each meeting the specific needs of a project. For this reason, choosing the correct type of pipe has a direct impact on network performance, reducing maintenance costs, and increasing the system’s useful life.
How Is a Polyethylene Pipe Made?
Polyethylene pipe is produced from high-density polyethylene (HDPE) raw material. Due to its high mechanical strength, corrosion resistance, good flexibility, and resistance to chemicals, this material is considered one of the best options for manufacturing fluid-transfer pipes.
Depending on the application, these pipes can be produced as single-wall or double-wall. Single-wall pipes are mostly used for transferring pressurized fluids, whereas double-wall pipes are designed for sewage networks, drainage, and buried projects.
Why Polyethylene Pipe?
In recent years, the use of polyethylene pipes has grown considerably due to their numerous advantages. The most important advantages of these products are:
- High resistance to corrosion and rust
- Good chemical resistance
- Light weight and easy transport
- Fast and low-cost installation
- High flexibility
- Resistance to ground settlement
- Good watertightness
- Reduced repair and maintenance costs
- Long service life
- Available in various sizes and classes
Types of Polyethylene Pipes
Polyethylene pipes are produced in various models according to the type of project, working pressure, and installation conditions. Each of these products is designed for a specific application.
Single-Wall High-Pressure Polyethylene Pipe
This type of pipe is designed for transferring water and other pressurized fluids and has broad applications in urban water supply networks, water transmission lines, pressurized irrigation systems, industries, and agricultural projects.
For a complete overview of the technical specifications, pressure classes, sizes, and applications of this product, please read the “Single-Wall High-Pressure Polyethylene Pipe” page.
Double-Wall Corrugated Polyethylene Pipe
The corrugated pipe, with its corrugated outer body and smooth inner surface, is one of the most common options for implementing sewage collection networks, directing surface water, and underground projects. This structure increases mechanical strength and improves hydraulic performance.
Complete information about this product is provided on the “Double-Wall Corrugated Polyethylene Pipe” page.
Double-Wall Spiral Polyethylene Pipe
The spiral pipe is designed for projects that require large diameters and high strength. This product is typically used in main sewage lines, treatment plants, infrastructure projects, and the transfer of large volumes of fluid.
For more information, see the “Double-Wall Spiral Polyethylene Pipe” page.
Double-Wall Carrytube Polyethylene Pipe
With its corrugated body and smooth inner surface, this product, in addition to high resistance to soil pressure and traffic loads, also provides uniform fluid flow. This pipe is used in urban sewage projects, cable ducting, road construction, industries, and civil construction projects.
The complete specifications of this product can be viewed on the “Double-Wall Carrytube Polyethylene Pipe” page.
Polyethylene Drainage Pipe
The drainage pipe is designed for collecting and directing subsurface water and controlling soil moisture. This product plays a very important role in managing excess water in agricultural, building, road construction, tunnel, retaining wall, landscaping, and green-space projects.
