Fire-Fighting Silicone Clamp Gasket

Core Product Features

1. Fire-Grade Material Performance

   Made of high-temperature resistant and flame-retardant silicone (ordinary silicone rubber/fluorosilicone rubber for regular use), it has a temperature resistance range of -60℃~200℃, adapting to the normal temperature water supply of fire pipelines in daily use and high-temperature environments in case of fire, and has certain flame retardancy with no toxic thick smoke generated when exposed to fire. The material is odorless and anti-aging, without swelling or hardening when in long-term contact with tap water and fire water. It can also resist aging and erosion from ultraviolet rays and humid environments when used in outdoor/underground pipelines, with a much longer service life than ordinary rubber gaskets.

2. High Elasticity & Strong Sealing, Adapted to Fire-Fighting Pressure Requirements

   Silicone material has excellent resilience and low permanent compression set (≤20%). After the clamp is locked, it can closely fit the sealing surface of pipeline joints and fill micro gaps. The regular model can withstand a nominal pressure of 1.6MPa~2.5MPa for fire pipelines, meeting the pressure test and daily water supply pressure requirements of fire pipe networks, and eliminating water leakage and seepage under high pressure.

3. Precise Adaptation to Clamps & Pipelines, Easy Installation

   Molded integrally according to the national standard dimensions of fire pipelines, the inner ring fits the outer wall of pipelines and the outer ring matches the sealing groove of fire grooved clamps with precise dimensions and no loosening. It is adapted to mainstream fire pipeline specifications such as DN50, DN80, DN100, DN150 and DN200. It realizes quick-install sealing with grooved clamps without glue or Teflon tape, and the sealing can be completed only by locking the clamps, which greatly improves the installation efficiency of fire pipelines and meets the requirements of rapid construction in engineering.

4. Excellent Medium Resistance, Adapted to Fire-Fighting Water Environment

   It is resistant to weak acids and weak alkalis, and can withstand trace disinfectants and minerals in fire tap water without corrosion or leachate, and will not block fire sprinkler heads, fire hydrants and other accessories. Meanwhile, it is resistant to water immersion, without degumming or deformation when in a full-water pipeline for a long time, ensuring the long-term stable sealing performance.

5. Structural Design Adapted to Fire-Fighting Grooved Joints

   Mostly of annular solid/hollow structure, some with a lip design that can enhance the fit with the sealing surface and improve the high-pressure sealing effect. The edges are rounded to avoid hand scratches during installation and prevent being cut when the clamp is locked, adapting to the quick installation operation at fire engineering sites.

Regular Specifications & Adaptation Standards

• Common specifications: DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250

• Adapted clamps: Fire grooved clamps, rigid clamps, flexible clamps (flexible gaskets can adapt to slight displacement of pipelines and reduce seal failure caused by vibration)

• Sealing surface adaptation: Standard grooved sealing surfaces of fire pipelines, applicable to all pipeline joints without burrs or damage

Application Scenarios

1. Indoor fire sprinkler pipe networks and fire hydrant pipelines of residential quarters, office buildings, shopping malls and other buildings;

2. Inlet and outlet pipeline connection of fire pump rooms and fire water tanks;

3. Outdoor fire pipe networks of municipal roads and industrial parks;

4. Fire water supply and drainage pipelines of industrial buildings such as warehouses and factories.

Key Points for Purchase & Use

1. Recognize fire-fighting adaptation standards: Prioritize products produced in accordance with national standards to ensure precise matching of dimensions with fire pipelines and clamps, avoiding poor sealing caused by non-standard dimensions;

2. Select materials on demand: Ordinary silicone rubber is sufficient for ordinary indoor fire pipelines; fluorosilicone rubber is recommended for high-temperature environments (such as boiler rooms, kitchen fire pipelines) and strong corrosive environments (such as fire pipelines in chemical parks) to improve high-temperature and corrosion resistance;

3. Inspection before installation: Clean dust, rust and burrs on the surface of pipeline joints and gaskets to avoid impurities affecting the sealing effect; the gasket must be completely embedded in the clamp sealing groove without displacement or distortion;

4. Strictly control installation force: Clamp bolts must be locked evenly to avoid uneven stress on the gasket caused by one-sided force and water leakage from local gaps;

5. Regular inspection and replacement: During the pressure test and daily patrol of fire pipe networks, if the gasket is found to be aged, hardened, cracked or the pipeline is leaking, it must be replaced in a timely manner to ensure the sealing performance of the fire system.
