Tapers are form-fitted elements used to connect pipes of varying diameters in drainage networks. Their role is to enable a streamlined size reduction, which helps prevent flow restriction, backflow, or leakage. When drainage systems are retrofitted, tapers offer a more reliable solution than forcing mismatched pipes together.
Taper Bends: Redirection and Size Change in One
Tapered elbow fittings 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 room is limited or multiple transitions are needed. They minimise the number of individual components, helping to lower failure points in the system.
Typical Fitting Locations
These fittings are frequently used across various drainage applications:
- In pump chambers, to join large outflow pipes 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 maintain consistent 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
- Blockages from sedimentation
- Accelerated joint degradation
Tapers and taper bends smooth these transitions out by evenly adjusting pipe size, improving flow performance and reducing long-term maintenance.
Why Choosing the Right Supplier Makes a Difference
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
- Industry-specific expertise
- Components meeting required standards
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 feature a longer and more gradual 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 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.
