Tapers are purpose-built elements used to connect pipes of varying diameters 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 offer a more stable solution than forcing mismatched pipes together.
Taper Bends: Redirection and Size Change in One
Tapered elbow fittings combine a directional change with a simultaneous reduction in diameter. 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 limit the number of individual components, helping to lower failure points 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
- Stress on seals and fittings
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:
- Comprehensive inventory options
- Products designed for field application
- 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 gentler size change, which is preferable for systems needing steady flow. Reducers often reduce quickly, which may impact flow stability.
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 material-specific, but adaptors can bridge the gap 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.
Making the Right Choice for Your System
Whether you're replacing a few here components or building a new network, fitting the correct tapers and taper bends is central to a low-maintenance and durable drainage setup.
