Product Description
Structural Design
- Overall Structure: This masterfully engineered assembly comprises dual flange plates, a resilient rubber sealing ring, a robust C-type clamp, and secure fasteners. The flange ends are equipped with precisely crafted grooves, ensuring the flanges are impeccably coupled through the clamp's sturdy hold. The centrally positioned rubber sealing ring plays an essential role, delivering an impeccable seal with unmatched precision.
- Dimension Specifications: Expertly crafted to accommodate pipeline diameters from DN15 to an impressive DN5000 mm, this design meets diverse connection requirements across a wide range of sizes. The thickness is meticulously tailored to factors such as pipe diameter and operational pressure, offering a spectrum from a slender 1.2 mm to a robust 2.5 mm, ensuring optimal performance.
Material Characteristics
- Strong Corrosion Resistance: Constructed using high-grade 304 and 316 stainless steel materials, this product is a paragon of corrosion resistance. It stands unwavering against rust and degradation even in acidic, alkaline, and saline environments, as well as in challenging humidity, ensuring long-lasting performance. This makes it the perfect fit for industries like chemical processing, petroleum, the food sector, and pharmaceuticals.
- High Strength: After undergoing specialized treatment, the stainless steel material reveals remarkable strength and hardness, capable of withstanding substantial pressure and tensile forces. This ensures steadfast connections within pipeline systems, maintaining stability without deformation or cracking even under demanding conditions.
- Hygienic and Environmentally Friendly: The non-toxic and harmless nature of stainless steel ensures that it won't contaminate transported media, complying with rigorous hygiene standards. It is especially well-suited for industries with stringent hygiene requirements, such as potable water and the food & beverage sectors.
Functional Features
- Convenient Installation: By embracing the grooved connection method, this innovative solution eliminates the need for welding. The installation process is quick and straightforward, enabling even non-specialized workers to execute it with minimal training. Connecting a single fitting takes mere minutes, significantly reducing construction time and enhancing efficiency, while also cutting down on labor and equipment costs.
- Reliable Sealing: The rubber sealing ring seamlessly complements the flange groove, while the clamp's secure fastening ensures no gas or liquid escapes, maintaining the connection's sealing integrity. It provides exceptional sealing performance even under high pressure or fluctuating temperatures in the pipeline.
- Good Detachability: This feature greatly simplifies pipeline maintenance, repair, and inspection. When disassembly, replacement, or repair is required, loosening the clamp allows for easy separation of flanges without causing any damage, thereby minimizing maintenance costs and complexity.
- Seismic and Noise Reduction: Effectively absorbs operational pipeline noise and vibration, thereby reducing system vibrations and noise. This enhances the stability and safety of the pipeline, contributing to an extended lifespan for both pipelines and equipment.
- Adapts to Thermal Expansion and Contraction: Expertly designed to accommodate the thermal expansion and contraction caused by temperature fluctuations, it prevents issues such as deformation, cracking, or seal failure due to thermal stress, ensuring the pipeline system operates smoothly and efficiently.
Application Fields
- Water Supply and Drainage Engineering: Extensively employed in municipal water pipeline projects, new community drinking water systems, and sewage treatment initiatives. It efficiently conveys various media, including potable water, sewage, and rainwater, within water supply and drainage systems.
- Fire Protection Systems: In the demanding environments of high-rise buildings, underground parking facilities, and industrial complexes, these grooved stainless steel flanges offer a dependable connection solution for fire protection pipelines, ensuring reliable water delivery during emergencies.
- Industrial Pipelines: Meticulously crafted to meet the demands of a wide array of pipeline systems, this exceptional flange is the preferred choice across key industrial sectors like chemical, petroleum, pharmaceutical, and food & beverage industries. Its design excels in managing diverse fluid media, whether corrosive or non-corrosive, such as acids, alkalis, salt solutions, oils, gases, and steam, guaranteeing a flawless and efficient transmission in every application.
- HVAC Systems: Within cutting-edge HVAC systems, including air conditioning and ventilation units, this flange serves as a vital link for connecting air conditioning and ventilation pipes. It not only ensures the uninterrupted flow of air and temperature-control media but also significantly boosts system efficiency with its outstanding shock absorption and noise reduction features, elevating overall system performance.
- Shipbuilding: Widely recognized for its application in the rigorous pipeline systems aboard ships, handling water supply, drainage, fuel oil, and lubricating oil lines with ease. The flange boasts superior corrosion resistance and reliable connection performance, making it ideally suited for the demanding marine environments faced by ships, delivering enduring reliability and operational efficiency.
