Our Stainless Steel Plate Flange (PL Flange) is a premium disc-shaped connecting component engineered for secure, leak-proof joints in piping systems, valves, pumps, and equipment interfaces. Crafted from high-grade stainless steel, this flange is designed to deliver exceptional durability, corrosion resistance, and structural integrity, making it ideal for a wide range of industrial and commercial applications. Unlike forged flanges, our plate flanges are machined from flat stainless steel plates, offering a cost-effective solution without compromising on performance for low to medium pressure environments.
Available in standard and custom specifications, our Stainless Steel Plate Flanges comply with global standards including ANSI B16.5, EN 1092-1, JIS B 2220, and ASTM A182, ensuring seamless compatibility with international piping systems and equipment. Whether for routine pipeline connections or demanding industrial scenarios, our plate flanges provide reliable performance and long service life.
Key Features & Advantages
Superior Corrosion Resistance: Made from high-quality stainless steel grades (304, 304L, 316, 316L, etc.), our plate flanges exhibit excellent resistance to general corrosion, stress corrosion cracking, crevice corrosion, pitting, and oxidation. This makes them suitable for use in harsh environments involving water, chemicals, seawater, and high-humidity conditions.
Precision Machining: Utilizing advanced CNC machining technology, our flanges feature precise dimensions, uniform bolt holes, and smooth sealing surfaces (available in Flat Face/FF and Raised Face/RF configurations) to ensure a tight, leak-proof seal when paired with gaskets. Every flange undergoes strict dimensional checks to meet standard requirements.
Easy Installation & Cost-Effective: With a simple flat disc design without a hub or neck, our plate flanges are easy to weld and align, reducing installation time and labor costs. They are a more economical alternative to forged flanges, making them ideal for large-scale projects and standard pipeline connections.
Wide Pressure & Size Range: Suitable for low to medium pressure applications (Class 150-Class 2500 / PN6-PN100) with a size range from DN15 to DN3000 (1/2″ to 120″), covering most industrial piping needs. Custom sizes and thicknesses (6mm-120mm) are available to meet specific project requirements.
High Durability & Longevity: The rugged construction and superior material properties ensure our Stainless Steel Plate Flanges can withstand heavy loads, high temperatures, and repeated use, minimizing maintenance needs and extending service life in long-term operations.
Global Standard Compliance: Fully compliant with international standards such as ANSI B16.5, ASTM A182, EN 1092-1, JIS B 2220, and DIN, ensuring interchangeability and compatibility with global piping systems and equipment.
Applications
Our Stainless Steel Plate Flanges are widely used in various industries and piping systems, thanks to their corrosion resistance, durability, and versatility. Key application areas include:
Petrochemical, chemical, and oil & gas industries
Water supply, drainage, and wastewater treatment systems
HVAC, fire protection, and ventilation systems
Food processing, pharmaceutical, and medical equipment
Steel plants, fertilizers, and power generation facilities
Shipbuilding, marine installations, and offshore projects
General industrial piping and structural utility connections
