What to Know About Tapers and Taper Bends in Drainage: Usage, Connection Fit, and Supply
Tapered connectors are form-fitted elements used to link pipes of different sizes in drainage networks. Their role is to facilitate a streamlined size reduction, which helps prevent flow restriction, backflow, or leakage. When drainage systems are modified, tapers provide a more stable solution than forcing mismatched pipes together.
Why Taper Bends Make Multi-Tasking Simple
Taper bends combine a shift in pipe direction with a simultaneous reduction in diameter. These fittings are most common 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 limit the number of individual components, helping to reduce joint fatigue in the system.
Typical Fitting Locations
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 compliance benchmarks for water management.
Importance of Correct Fitting Size
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
- Better material suitability
- Industry-specific expertise
- Proven quality assurance
A dedicated supplier will have fittings that are not only dimensionally correct but also engineered for actual site demands—ensuring long-term system integrity.
FAQs
Is a taper the same as a reducer?
No. Tapers feature a longer and more gradual size change, which is preferable for systems needing steady flow. Reducers often transition over a short length, which may impact flow stability.
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 material-specific, 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 avoiding abrupt transitions.
What size taper should I choose?
Measure both ends and factor in hydraulic design to select the correct taper size for the application.
