Stainless Steel Plate Flanges

What are Plate flanges?

Plate flanges, often known as flat flanges, plain flanges, or slip-on flanges, are fundamental components in many piping systems, offering a practical and cost-effective solution for joining pipes. These flat, circular discs are designed for secure attachment to the end of a pipe, facilitating a robust, bolted connection to another pipe or fitting.

Common Material Options:

1. Carbon Steel:

Standards: Conforming to ASTM/ASME A/SA 105, A516 Gr.70, and A36.
Applications: An excellent balance of economy and durability, carbon steel flanges are well-suited for applications involving moderate pressure and temperature ranges.

2. Stainless Steel:

Standards: Manufactured to ASTM A182 and A240 (available in grades 304, 316, 321).
Applications: Offering superior corrosion resistance, stainless steel is the ideal choice for demanding environments such as chemical processing plants and marine installations where resistance to aggressive media is critical.

3. Specialty Alloys:

Materials: Including Duplex and Super Duplex Steel (ASTM A182 F51, F53), and high-performance Nickel Alloys (like Inconel 625, Monel 400).
Applications: These advanced alloys are specifically engineered for the most extreme conditions, providing unparalleled performance in high-pressure, high-temperature, or exceptionally corrosive industrial settings.

Steel Plate Flanges Key Features:

Exceptional Sealing Capability: Engineered to create tight, leak-proof joints, crucial for maintaining system integrity in various applications.
Robust Structural Support: Beyond just sealing, these flanges add significant mechanical strength to piping connections, enhancing overall system stability.
Versatile Connection Methods: Designed for compatibility with multiple attachment techniques, including welding for a permanent fixture, bolting for secure assembly, or screwing for specific applications.
Cost-Efficient Solution: Benefiting from a simpler manufacturing process compared to more complex flange types, plate flanges offer an economical advantage without compromising on quality or performance.

Material Selection for Industry Steel Plate Flanges

The choice of material is paramount for the longevity and performance of steel plate flanges. It must align perfectly with the operational environment, taking into account factors like system pressure, operating temperature, and exposure to corrosive substances.

Steel Plate Flanges Advantages?

At their core, plate flanges are about straightforward, reliable connections. They are typically welded onto the end of a pipe, creating a surface that can then be bolted to another flanged component with a gasket sandwiched in between. This simple yet effective design is widely employed in essential infrastructure like fuel and water pipelines.
One significant advantage of plate flanges lies in their adaptability during construction. When precise pipe lengths are unknown or minor misalignments occur in a pipeline run, plate flanges can be welded with a slight offset, allowing for flexible adjustments and ensuring that two pipes, even if not perfectly aligned, can still be joined securely.
Our plate flanges feature a distinctive serrated finish on the inner mating surface. This crucial detail ensures an excellent grip, allowing the flange to effectively embed within the gasket material for a superior, leak-proof seal. Furthermore, the design of plate flanges adheres to standardized dimensions, guaranteeing interchangeability and consistent performance, regardless of the specific material used in their manufacture.
