Product Description
304/316L Stainless Steel Plate Flat Flange
Corrosion-resistant ANSI/DIN standard flange for industrial low-pressure applications
Product Overview
Stainless Steel Plate Flat Flange is a cost-effective, reliable component designed for low-pressure industrial piping systems. Manufactured from premium 304/316L stainless steel, this flange features a flat face and compact structure, providing excellent corrosion resistance and straightforward installation for pipe and equipment connections.
Key Features & Benefits
- Flat face design ensures tight gasket sealing for low-pressure media
- Direct welding to pipes/equipment simplifies installation and reduces costs
- Compact structure ideal for simple pipelines and light industrial applications
- Available in 304 grade for general use and 316L for enhanced corrosion resistance
- Compliant with ANSI/ASME B16.5, DIN 2627, EN 1092-1 standards
- Comprehensive quality checks ensure dimensional accuracy and surface integrity
Applications
Widely used in municipal water systems, HVAC applications, light manufacturing facilities, and auxiliary pipelines. 304 variants suit general low-pressure environments, while 316L variants provide superior performance in mild chemical processing, coastal installations, and marine auxiliary systems.
