Discover the exceptional quality and durability of our stainless steel grooved flanges, expertly crafted by Wenzhou Safety Stainless Steel Co., Ltd. These heavy-duty components are designed to meet the most demanding industrial applications, featuring an innovative RF sealing surface design to ensure a reliable and leak-proof connection. Perfect for various engineering and construction needs, our flanges offer unmatched performance and longevity.
Product Description
Structural Design
- Overall Structure: Crafted with precision, our Heavy-Duty Steel Grooved Flange is ingeniously constructed from two robust flange plates, a durable rubber sealing ring, a resilient C-type clamp, and fortified fasteners. The grooved connecting ends of the flanges are engineered to ensure a tight and seamless connection, secured by the clamp with the rubber seal efficiently positioned in the middle, guaranteeing optimal sealing capabilities.
- Dimension Specifications: Designed with versatility, the pipeline diameter elegantly spans from DN15 to DN5000 mm, adeptly accommodating the diverse connection needs of varying pipeline sizes. The thickness, a testament to its robust quality, varies in accordance with the pipe diameter and operational pressure, typically ranging between a solid 1.2-2.5 mm.
Material Characteristics
- Strong Corrosion Resistance: Meticulously crafted from premium stainless steel grades such as 304 and 316, this product boasts superior anti-corrosion features. Resistant to rust and deterioration in a wide array of acidic, alkaline, and saline solutions, as well as in demanding environments, it assures unwavering performance for extended periods. Perfectly suited for application across industries like chemical, petroleum, food, and pharmaceutical, where durability and reliability are paramount.
- High Strength: Through advanced treatment processes, the stainless steel's inherent strength and hardness are significantly enhanced, ready to endure immense pressure and tensile forces. This ensures the steadfastness of pipeline connections, maintaining stability without deformation or cracking, even under the most challenging working conditions.
- Hygienic and Environmentally Friendly: The non-toxic and harmless nature of stainless steel guarantees that it does not contaminate the substances it conveys. Compliant with stringent hygiene standards, it is ideal for applications demanding the highest hygiene levels, including drinking water supply and the food & beverage industry.
Functional Features
- Convenient Installation: Embracing the grooved connection technique, this product negates the need for welding, streamlining the installation process to be both swift and straightforward. Even personnel with basic training can efficiently handle the setup, as connecting a single fitting requires mere minutes, effectively reducing construction time, boosting productivity, and cutting down on both labor and machinery expenses.
- Reliable Sealing: The meticulously designed rubber sealing ring seamlessly integrates with the flange groove. When combined with the clamp's fastening prowess, it offers a formidable defense against gas and liquid leaks, ensuring exceptional sealing performance. This reliability is maintained even under fluctuating pipeline pressures and temperatures.
- Good Detachability: This feature greatly simplifies pipeline maintenance, repair, and inspection processes. When disassembly, replacement, or repair of the pipeline is necessary, simply loosening the clamp allows for the flanges to be separated with ease, without any damage to either the pipeline or the flanges, thus reducing both maintenance costs and complexity.
- Seismic and Noise Reduction: Designed to absorb operational noise and mitigate the vibrations within the pipeline, this feature significantly reduces the noise and vibration of the system, enhancing the stability and safety of the pipeline. This contributes to an extended lifespan for both the pipelines and associated equipment.
- Adapts to Thermal Expansion and Contraction: Expertly crafted to accommodate the natural thermal expansion and contraction of pipelines due to temperature variations. This adaptation prevents issues such as deformation, cracking, or sealing failures caused by thermal stress, ensuring the seamless operation of the pipeline system.
Application Fields
- Water Supply and Drainage Engineering: This versatile product finds extensive application in municipal tap water pipeline projects, new community direct drinking water initiatives, sewage treatment systems, and more. It's engineered to transport a variety of water supply and drainage media, including drinking water, sewage, and rainwater, with unmatched efficiency.
- Fire Protection Systems: In the critical fire protection systems of towering high-rise buildings, subterranean parking facilities, sprawling industrial parks, and beyond, our grooved stainless steel flanges offer an efficient and steadfast connection solution. They ensure the reliable delivery of fire protection water during emergencies, safeguarding lives and properties.
- Industrial Pipelines: Perfectly engineered for pipeline systems across diverse industrial sectors such as chemical, petroleum, pharmaceutical, and food & beverage industries. These robust flanges adeptly transport a wide array of fluid media, whether corrosive or non-corrosive, including acids, alkalis, salt solutions, oils, gases, steam, and more.
- HVAC Systems: In HVAC systems, such as air conditioning and ventilation setups, this flange is indispensable for connecting air conditioning pipes, ventilation ducts, and more. It guarantees the seamless delivery of air and thermal media while also offering superior shock absorption and noise attenuation.
- Shipbuilding: Extensively utilized in shipboard pipeline systems for water supply, drainage, fuel oil, and lubricating oil management. Its exceptional corrosion resistance and reliable connectivity ensure it meets the challenging demands of maritime environments, providing durability and robust performance.
