Tapered connectors are form-fitted elements used to unite pipes of different sizes in drainage networks. Their role is to ensure a streamlined size reduction, which helps reduce the chance of flow restriction, backflow, or leakage. When drainage systems are modified, tapers provide a more stable solution than forcing mismatched pipes together.
Taper Bends: Redirection and Size Change in One
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 cut down on the number of individual components, helping to reduce joint fatigue in the system.
Typical Fitting Locations
These fittings are widely installed 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 regulatory standards 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 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
- 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 offer a longer and gentler size change, which is more effective for systems needing steady flow. Reducers often reduce quickly, which may create turbulence.
Can taper bends be used underground?
Yes, as long as they’re compliant with underground use requirements and follow relevant local guidelines.
Are tapers compatible with clay and plastic pipes?
Tapers are usually manufactured for one pipe type, but adaptors can bridge the gap between clay, plastic, and other pipe materials.
Do taper bends reduce flow performance?
If correctly selected and installed, taper bends maintain consistent flow and can even improve it by reducing pressure drops.
What size taper should I choose?
Measure both ends and factor in hydraulic design to select the correct taper size for the application.
