1.5 inch pvc pipe fittings introduction
1.5 inch (i.e. 1½ inch) PVC pipe fittings are common fittings in pipe systems, mainly used to connect, turn, divert or terminate pipes to ensure smooth fluid delivery and system stability. They are widely used in water supply and drainage systems, irrigation systems, industrial pipes and ventilation pipes, and are favored by engineers and home users for their light weight, durability, strong corrosion resistance and easy installation.
Common size specifications of 1.5 inch pvc pipe fittings
The size of 1.5 inch pvc pipe fittings usually matches the nominal diameter (Nominal Pipe Size, NPS), and the actual outer diameter and pipe opening are slightly larger than 1.5 inches to accommodate the plugging or bonding of PVC pipes. The following are the specifications of common pipe fittings:
1. Elbow
Elbows are used to change the direction of pipes, and common angles are 45° and 90°.
90° elbow: outer diameter is about 48.26mm, inner diameter is slightly larger than 1.5 inches, and the plug depth is usually 30-35mm.
45° elbow: used for smoother direction conversion, reducing water flow resistance, and the size is similar to 90° elbow.
2. Tee
Used to form branches in pipes, mainly equal-diameter tees and reducing-diameter tees.
Equal-diameter tees: All three interfaces are 1.5 inches, suitable for connecting pipes of the same diameter.
Reducing Tee: The main interface is 1.5 inches, and the branch pipe can be 1 inch, ½ inch, etc.
3. Direct Coupling
Used to connect two 1.5-inch PVC pipes to ensure the continuity of the pipe.
Standard direct coupling: The inner diameter is slightly larger than 1.5 inches, so that the pipe can be sleeved, and the length is about 50-70mm.
Repair Coupling: No stop design, convenient for pipe repair and replacement.
4. Reducer Coupling
Used to connect PVC pipes of different sizes. Common reducer specifications are:
1.5 inches to 1 inch
1.5 inches to ¾ inch
5. End Cap
Used to close the pipe port to prevent dust or foreign matter from entering, or for system testing.
Outer diameter is about 50mm, height is 30-40mm, with glue groove or thread structure on the inside.
6. Flange
Used for pipes that require detachable connections, commonly found in industrial pipes and high-pressure systems.
The outer diameter of a 1.5-inch flange is usually 95-120mm, with 4-6 bolt holes.
7. Wye
Provides a 45° angle diversion, suitable for drainage systems, reduces water flow resistance, and prevents blockage.
8. Drain Valve
Used for drainage systems or irrigation systems, usually with a threaded interface for easy disassembly and maintenance.
Main applications
1. Water supply and drainage system
Household water supply: used for hot and cold water transportation in kitchens, bathrooms, laundry rooms and other areas.
Sewage discharge: connected to the drainage network to ensure smooth sewage discharge.
Rainwater collection: used for roof drainage and rainwater storage system.
2. Agricultural irrigation
Drip irrigation and sprinkler irrigation system: connected to the irrigation main pipe to distribute water to the field.
Greenhouse planting: PVC pipe fittings are used to connect the spraying device to improve irrigation efficiency.
3. Industrial pipelines
Chemical fluid transportation: PVC material is corrosion-resistant and suitable for low-pressure transportation of chemicals and solutions.
Ventilation ducts: used in laboratories and industrial ventilation systems to transport non-high-temperature gases.
4. Swimming pools and aquariums
Filtration system: used for water circulation and purification systems.
Fountains and landscape pools: PVC pipe fittings are used for water flow control and landscaping systems.
5. Cable protection pipes
Underground cable protection: used to bury power and telecommunications cables to prevent damage.
Bridges and tunnels: used for wire casings to ensure safety and durability.
Installation and maintenance
1. Installation method
Glue bonding: Use PVC special glue to ensure sealing.
Threaded connection: Suitable for detachable systems, such as valves and maintenance ports.
Flange connection: Used for high-pressure fluids or pipe systems that require frequent disassembly and assembly.
2. Maintenance recommendations
Regularly check the joints for leakage, especially the bonding parts.
Avoid exposure to sunlight. It is recommended to use UV-resistant PVC pipe fittings or wrap them in a protective layer.
Clean the inner wall of the pipe to prevent dirt accumulation from affecting fluid flow.
1.5 inch pvc pipe fittings are widely used in water supply and drainage, agricultural irrigation, industry, swimming pool systems, cable protection and other fields due to their standardized size, convenient installation and strong corrosion resistance. Its common sizes include elbows, tees, direct joints, reducers, flanges, etc., which are suitable for various scenarios. Choosing the right 1.5-inch PVC pipe fittings can effectively improve the durability and reliability of the pipeline system while reducing maintenance costs.
If you are looking for 1.5-inch PVC pipe fittings, it is recommended to choose the appropriate type according to the specific usage scenario and ensure that it meets the relevant standards to ensure the safety and long-term use of the system.
