Tapers are purpose-built elements used to connect pipes of different sizes in drainage networks. Their role is to enable a gradual size reduction, which helps avoid flow restriction, backflow, or leakage. When drainage systems are expanded, tapers provide a more secure solution than forcing mismatched pipes together.
Taper Bends: Redirection and Size Change in One
Tapered elbow fittings combine a directional change with a simultaneous pipe size transition. These fittings are typically available in angles such as 11°, 22.5°, 45°, or 90°, and they’re particularly valuable in installations where space is restricted or multiple transitions are needed. They minimise the number of individual components, helping to reduce joint fatigue in the system.
Where Tapers and Bends Are Commonly Used
These fittings are frequently used across various drainage applications:
- In pump chambers, to join outlets to smaller distribution lines
- Throughout retrofit projects with updated or non-standardised pipework
- Across field drainage systems where flow rates and gradients must be kept steady
- Inside wastewater facilities where components need to be space-saving and multi-functional
Correctly applied, these fittings optimise flow, reduce energy loss from turbulence, and help meet regulatory standards for water management.
Why Size Precision Matters
Incorrectly sized joints can cause:
- Disturbances in hydraulic pressure
- Build-up of debris
- Stress on seals and fittings
Tapers and taper bends create an even flow path by offering a controlled reduction, improving flow performance and reducing long-term maintenance.
Benefits of Using a Specialist Supplier
Choosing a general merchant might offer convenience, but a specialist drainage supplier brings:
- Greater range of product sizes and angles
- Products designed for field application
- Product advice from experience
- Proven quality assurance
A dedicated supplier will have fittings that are not only dimensionally correct but also proven in field conditions—ensuring long-term system integrity.
FAQs
Is a taper the same as a reducer?
No. Tapers offer a longer and gentler size change, which is more effective for systems needing steady flow. Reducers often transition over a short length, which may create turbulence.
Can taper bends be used underground?
Yes, provided they are made from suitable materials and follow relevant local guidelines.
Are tapers compatible with clay and plastic pipes?
Tapers are usually manufactured for one pipe type, but adaptors can allow connection between clay, plastic, and other pipe materials.
Do taper bends reduce flow performance?
If properly integrated into the system, taper bends maintain consistent flow and can even improve it by reducing pressure drops.
What size taper should I choose?
Base your choice on pipe diameter and system flow requirements to select the correct taper size for the application.
