A Guide to Tapers and Taper Bends in Drainage Systems: Function, Compatibility, and Supply
Reducer fittings in drainage systems are purpose-made adaptors that enable a smooth transition between pipes of differing diameters. Rather than forcing incompatible pipes together—which can cause leaks—these fittings ensure a secure connection, especially during system upgrades where pipe sizes may vary.
Taper Bends: Combining Direction and Diameter Change
Taper bends perform two tasks at once. They redirect flow—commonly at angles like 11°, 22.5°, 45°, or 90°—while also adapting the pipe diameter. This dual-purpose design is particularly valuable in compact drainage systems, where reducing the number of joints also reduces leak risks.
Where Are Tapers and Taper Bends Used?
These fittings are commonly seen in both agricultural and commercial drainage systems. Examples include:
- Pump chambers where a large outlet connects to smaller downstream pipes
- Modernised systems where pipe dimensions have changed over time
- Subsurface water management systems requiring efficient flow with minimal disruption
- Wastewater treatment plants where space is limited and fittings must perform multiple functions
In all cases, correct installation ensures steady flow, reduced turbulence, and compliance with regional environmental regulations.
The Importance of Fit: Avoiding Flow Disruption
Improperly sized connections can negatively impact fluid dynamics within the system. This may lead to:
- Unwanted pressure variations
- Accumulated debris
- Premature wear on joints and seals
Tapers and taper bends address these issues by providing controlled diameter transitions, which support optimal flow and help preserve the longevity of the system.
The Value of Choosing a Dedicated Supplier
While general stockists may offer convenience, drainage-specific suppliers deliver more in terms of:
- Access to a broader range of dimensions
- Angle variations
- Expert guidance
- Reliable product performance
- Compliance with standards
Choosing a supplier specialising in drainage ensures your components are installation-ready, reducing risk and improving system resilience.
FAQs
What’s the difference between a taper and a reducer?
A taper offers a longer, smoother change in diameter, while reducers have a more abrupt shift in size. Tapers are often preferred where minimising turbulence is important.
Are taper bends suitable for underground use?
Yes, as long as they comply with underground fitting standards and are made from approved materials.
Can tapers connect clay and plastic pipes?
While most tapers are designed for one pipe type, adaptors are available for transitions between clay and plastic systems.
Do taper bends impact flow compared to straight pipe?
When appropriately specified, taper bends do not restrict flow and may even reduce turbulence when compared to sudden directional or size changes.
How do I determine the correct taper size?
Check the inlet and outlet dimensions of the pipes to be connected. System specifications should also be considered to ensure compatibility and performance.
Choosing the Right Fitting Matters
Whether your project is a small-scale job or a complete upgrade, check here choosing the appropriate tapers and taper bends is vital. They support the structural and hydraulic integrity of the drainage system, keeping it efficient over time.
