In modern pipeline engineering, high-density polyethylene (HDPE) pipe fittings have become an ideal choice for various pipeline connections due to their excellent performance and wide applicability. Among them, the Junrui brand is favored by users for its high quality and professional production process. Junrui’s 4 inch HDPE pipe fittings are an important part of its product line and are widely used in water supply and drainage, gas transmission, agricultural irrigation and other fields. This article will elaborate on the characteristics, main types, application fields, installation methods and maintenance recommendations of 4 inch HDPE pipe fittings.
Basic Overview of 4-inch HDPE Pipe Fittings
4-inch HDPE pipe fittings refer to fittings used to connect HDPE pipes with an outer diameter of 4 inches (about 114 mm), usually made of high-density polyethylene material. Junrui brand 4-inch pipe fittings are based on high-quality raw materials and strict production processes to ensure that the products have superior performance and long service life.
The main product categories include:
Elbow: used to change the direction of the pipeline (commonly 45°, 90°).
Tee: used for branch pipeline connection, divided into equal-diameter tees and reducing tees.
Flange connector: suitable for detachable connection between pipes and valves or other equipment.
Reducer: used for connection between pipes of different sizes.
End cap: used to close the end of the pipe.
Features of HDPE pipe fittings
1. Excellent material properties
Junrui pipe fittings are made of high-density polyethylene raw materials and have the following characteristics:
2. Strong corrosion resistance: acid and alkali resistance, chemical medium corrosion resistance, suitable for harsh environments.
UV resistance: UV stabilizers are added to the material, which can be used outdoors for a long time without aging.
High toughness: Good impact resistance can be maintained even in low temperature environments.
3. High connection reliability
The hot-melt butt and electric fusion connection methods of Junrui pipe fittings ensure the firmness of the connection, which can achieve the same strength as the pipe body and avoid the risk of leakage or rupture.
4. Lightweight and easy to install
HDPE pipe fittings are light in weight, easy to transport and install, and do not require complex construction equipment, reducing labor costs.
5. Environmental protection and recyclability
HDPE materials are non-toxic and odorless, have no pollution to the environment, can be recycled after disposal, and meet modern environmental protection requirements.
6. Long service life
Junrui’s pipe fittings can have a service life of more than 50 years under normal conditions, greatly reducing long-term maintenance costs.
Main application areas of Junrui 4 inch HDPE pipe fittings
1. Water supply and drainage system
Junrui pipe fittings are commonly used in water supply and drainage pipelines in urban buildings, residential communities and industrial sites. Its corrosion resistance and non-leakage characteristics are particularly suitable for conveying domestic water and sewage.
2. Gas transmission
The pressure resistance and chemical corrosion resistance of HDPE pipe fittings make it an ideal choice in gas transmission systems.
3. Agricultural irrigation
In agriculture, 4-inch HDPE pipe fittings are widely used in field irrigation, drip irrigation and sprinkler irrigation systems. Its weather resistance and flexibility help improve irrigation efficiency.
4. Industrial pipelines
Junrui HDPE pipe fittings can withstand certain pressure and chemical erosion, and are suitable for conveying industrial wastewater, chemical liquids, etc.
5. Cable protection
4-inch HDPE pipe fittings can be used as cable protection sleeves to prevent cables from external mechanical damage.
Installation method of HDPE pipe fittings
1. Butt fusion welding
Scope of application: commonly used for connecting straight pipes and pipe fittings.
Steps:
Use HDPE Buttfusion Welding Machine to heat the connecting end faces of pipe fittings and pipes.
When heating is completed, quickly butt the two ends and maintain a certain pressure until cooling.
Features: Firm connection and high sealing.
2. Electrofusion connection
Scope of application: complex pipeline systems or scenes requiring high-precision connection.
Steps:
Insert pipe fittings and pipes into electrofusion pipe fittings.
Use HDPE ElectroFusion Welding Machine to provide heating current to melt the inner wall of the pipe fittings and connect them firmly.
Features: Easy operation and suitable for on-site construction.
3. Flange connection
Scope of application: Pipes that need to be connected to valves or other equipment.
Steps:
Connect the pipe fittings to the flange and install a sealing gasket between the flanges.
Tighten the flange with bolts to ensure a stable connection.
Features: Easy to disassemble and assemble, suitable for maintenance and repair.
