Types of SWR pipes

When it comes to plumbing applications, SWR (Soil, Waste, and Rainwater) pipes play a crucial role in ensuring efficient and reliable drainage systems. Among the various types available, Type A and Type B SWR pipes & fittings are widely used for specific purposes. This article aims to shed light on the characteristics, applications, and advantages of these two types of SWR pipes.

  1. Type A SWR Pipes: Type A SWR pipes are primarily designed for rainwater and venting applications. They feature a smooth inner surface and are distinguished by their vibrant blue color. These pipes have a wall thickness of 1.6 mm, providing adequate strength and durability for their intended use. Key features of Type A SWR pipes include:
  • Smooth inner surface for enhanced flow rates.
  • Lightweight construction for easy installation.
  • Resistance to corrosion, ensuring a longer lifespan.
  • UV stabilization allows outdoor usage without degradation.
  • Ideal for residential and commercial rainwater and venting applications.
  1. Type B SWR Pipes: Type B SWR pipes, on the other hand, are specifically engineered for soil and waste discharge applications. These pipes also possess a smooth inner surface, facilitating efficient drainage. Type B SWR pipes are easily recognizable by their clean white color and have a slightly thicker wall thickness of 2.2 mm. The key features of Type B SWR pipes include:
  • Adequate wall thickness for increased durability and strength.
  • Smooth inner surface promoting optimal flow and preventing clogs.
  • Lightweight nature making installation hassle-free.
  • Excellent resistance to corrosion, ensuring a longer lifespan.
  • Suitable for soil and waste discharge applications in various settings.

Benefits of Using SWR Pipes:

Regardless of the type, SWR pipes offer several advantages over alternative plumbing materials. Here are some benefits of using SWR pipes:

  1. Lightweight and Easy Installation: SWR pipes are lightweight, making them easy to handle and install. This characteristic saves time and effort during the installation process, reducing labor costs.
  2. Durability and Corrosion Resistance: Both Type A and Type B SWR pipes are crafted from UPVC (unplasticized polyvinyl chloride), which imparts exceptional durability and resistance to corrosion. This longevity ensures that the pipes can withstand harsh conditions and provide long-term functionality.
  1. UV Stabilization for Outdoor Use: The UV-stabilized composition of SWR pipes allows them to be used outdoors without degrading or deteriorating. This feature makes them suitable for applications such as rainwater harvesting and external drainage systems.
  1. Smooth Inner Surface for High Flow Rates: The smooth inner surface of SWR pipes facilitates excellent flow rates, minimizing the chances of clogs or blockages. This attribute ensures efficient drainage and reduces the risk of system failures.
  1. Leak-Proof Joints: SWR pipes can be joined using solvent cement or push-fit connectors, ensuring leak-proof connections. This feature enhances the overall integrity and reliability of the plumbing system, preventing leakage-related issues.

SWR pipes, specifically Type A and Type B, offer reliable solutions for various plumbing applications. Their lightweight construction, durability, resistance to corrosion, UV stabilization, smooth inner surface, and leak-proof joints make them an excellent choice for both residential and commercial plumbing needs. By understanding the characteristics and benefits of SWR pipes, plumbing professionals and homeowners can make informed decisions when selecting the appropriate pipe type for their specific requirements.
