Product Overview
3 inch hdpe pipe, that is, high-density polyethylene pipe with a diameter of 3 inches, is a pipe made of high-density polyethylene (abbreviated as HDPE) material. HDPE is a highly crystalline, non-polar thermoplastic resin with excellent corrosion resistance, wear resistance, insulation and long service life. It has been widely used in many fields. Due to its unique performance and wide application fields, 3-inch HDPE pipe has become one of the indispensable pipes in the modern engineering field.
Product characteristics
Excellent corrosion resistance:
HDPE pipes can resist the corrosion of a variety of chemical media, including a variety of acids, bases, salts and so on. The chemicals present in the soil do not cause any degradation of the pipe.
Polyethylene is an electrical insulator and therefore does not decay, rust or electrochemical corrosion occur.
Good wear resistance:
The wear resistance of HDPE pipe and steel pipe is 4 times that of steel pipe.
In the field of mud transportation, compared with steel pipes, HDPE pipes have better wear resistance, which means that HDPE pipes have longer service life and better economy.
Low temperature impact resistance is good:
The low temperature embrittlement temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60 ° C 60 ° C (or -40 ° C 100 ° C).
During construction in winter, the pipe cracking will not occur because of the good impact resistance of the material.
Good stress cracking resistance:
HDPE has low notch sensitivity, high shear strength, excellent scratch resistance, and outstanding environmental stress cracking resistance.
Light weight, convenient construction:
The HDPE pipeline is light in weight, convenient in construction, can be prefabricated in advance, and the installation efficiency is greatly improved.
Smooth inner wall, low flow resistance:
The HDPE pipe has a smooth inner surface and a Manning coefficient of 0.009, which can effectively reduce energy consumption.
Reliable connection:
The strength of the joint is higher than the strength of the pipe body.
Good flexibility:
The flexibility of the HDPE pipe makes it easy to bend and can be engineered to bypass obstacles by changing the direction of the pipe.
A variety of new construction methods:
In addition to the traditional excavation method for construction, a variety of new trenchless technologies can be used, such as pipe jacking, directional drilling, liner, split pipe, etc.
3 inch hdpe pipe Application fields
3 inch HDPE pipe has been widely used in many fields due to its excellent performance:
Municipal engineering:
Used in urban tap water pipes, sewage pipes and rainwater pipes, etc.
Agricultural irrigation:
Especially suitable for water pipes and sprinkler pipes in agricultural irrigation systems, which improves irrigation efficiency and reduces maintenance costs.
Petrochemical:
Used to transport various corrosive media.
Environmental protection engineering:
It plays an important role in environmental protection projects such as sewage collection and treatment, biogas projects, landfills, etc.
Other fields:
It is also widely used in power, communications, fire protection and other fields as cable protection sleeves, thermal pipes or fire protection system supply lines, etc.
3 inch hdpe pipe Precautions
1. Choose the right connection method:
Choose the right connection method according to the pipe diameter. For example, when DN≤63, use injection hot melt socket connection; when DN≥75, use hot melt butt connection or electric fusion socket connection.
2. Avoid long-term high temperature exposure:
HDPE pipes will soften at high temperatures, and long-term high temperature exposure should be avoided to avoid affecting their performance.
3. Pay attention to construction protection:
During the construction process, care should be taken to protect the pipeline from damage to ensure the integrity and reliability of the pipeline system.
3 inch HDPE pipe has become one of the indispensable pipes in the modern engineering field with its excellent performance and wide application fields. In the process of selection and use, its characteristics and precautions should be fully understood to ensure its normal operation and extend its service life.
