What to Know About Tapers and Taper Bends in Drainage: Usage, Fitting Accuracy, and Supply

Tapers are specifically designed elements used to unite pipes of varying diameters in drainage networks. Their role is to facilitate a streamlined size reduction, which helps reduce the chance of flow restriction, backflow, or leakage. When drainage systems are expanded, tapers offer a more secure solution than forcing mismatched pipes together.



Why Taper Bends Make Multi-Tasking Simple



Taper bends combine a directional change with a simultaneous pipe size transition. These fittings are typically available in angles such as 11°, 22.5°, 45°, or 90°, and they’re particularly effective 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.



Where Tapers and Bends Are Commonly Used



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.



Why Size Precision Matters



Incorrectly sized joints can cause:




  • Disturbances in hydraulic pressure

  • Build-up of debris

  • Accelerated joint degradation



Tapers and taper bends create an even flow path 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 gentler size change, which is preferable for systems needing steady flow. Reducers often transition over a short length, 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 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 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.



Choose Smart, Fit Once



Whether you're replacing a website few components or building get more info a new network, fitting the correct tapers and taper bends is central to a low-maintenance and durable drainage setup.
