Description

The Walraven 2S Unlined Clamp is a robust, high-quality pipe support solution designed for secure and reliable fixing of various pipe systems. Manufactured from zinc-plated steel, it offers excellent corrosion resistance and durability, making it ideal for both commercial and industrial installations. 

Unlike lined versions, this unlined model is particularly well-suited for use with insulated pipe supports, as it provides a firm, metal-to-metal connection without compressing or damaging insulation material. This makes it the perfect choice for systems where thermal insulation integrity must be maintained, such as in heating, cooling, or chilled water applications. Durable, easy to install, and designed with professional installers in mind, this product delivers both mechanical reliability and installation convenience.

What does Gapless mean?
  • Gapless clamps are engineered to close completely when tightened, leaving no visible gap between the clamp halves. This design ensures uniform compression and a secure hold around the pipe, reducing vibration, noise, and potential slippage. The even pressure distribution helps extend the lifespan of both the pipe and the support system.
What are Anti-Loss Washers?
  • Anti-loss washers are integrated components designed to keep the clamp screws securely attached, even when loosened. They prevent screws from falling out during installation or adjustment, allowing for faster, easier one-handed operation. This feature not only improves installation efficiency but also minimises the risk of losing parts on site.
What are Insulated Pipe Supports?
  • Insulated pipe supports are designed to maintain the thermal integrity of insulated pipework. They provide structural support while preventing heat loss (in hot systems) or condensation (in cold systems). When used with unlined clamps, they allow the insulation material to remain intact, ensuring energy efficiency and system performance are preserved throughout the pipe network. For example, the Walraven Phenblox Phenolic Insulation Blocks.

Key Features & Benefits

  • Gapless Design: Guarantees full contact around the pipe for optimal support and vibration control.
  • Anti-Loss Washers: Prevent screws from dropping out during installation for added safety and convenience.
  • Ideal for Insulated Pipes: Provides secure support without damaging insulation layers.
  • Corrosion Resistant: Zinc-plated finish ensures long-lasting protection in demanding environments.
  • Professional Quality: Built for quick, reliable, and consistent installation across varied applications.
