Plate Flanges
Riyaarth Overseas is a leading manufacturer and exporter of premium ASME/ANSI/DIN standard plate slip-on flanges in India. We specialize in rapid delivery of standard carbon steel and stainless steel plate flanges, with the ability to manufacture custom sizes as per client requirements. Our plate flanges are widely used in various industries and offer a reliable, cost-effective solution for low-pressure applications.
Plate flanges, also known as slip-on flanges, are commonly used in low-pressure piping systems. They are highly valued for their simplicity, ease of installation, and cost-effectiveness. These flanges are produced by machining flat plate materials, which makes them a perfect alternative to cast or forged flanges in less demanding applications.
Advantages of Plate Flanges:
- Defect-Free: Plate flanges are free from casting or forging defects, providing superior reliability.
- Improved Grain Structure: Compared to cast or forged flanges, the grain structure of plate flanges is enhanced, offering extended service life.
- Reduced Maintenance Costs: The design and material characteristics of plate flanges help lower maintenance expenses over time.
