D J Metal Industries specialized in the manufacturing, supply, and export of Stainless Steel Spectacle Blind Flanges. SS Spectacle Blind Flange consists of two metal discs connected by a metal section, forming a ‘figure 8’ flange. The primary function of the Stainless Steel Spectacle Blind Flange is to prevent any leaks from the pipeline during maintenance. Stainless Steel Spectacle Blind Flanges serve as pressure-retaining plates in high-pressure piping networks. Our ANSI / DIN / BS Standard Spectacle Blind Flanges can be easily rotated to control the flow of pipes, making them suitable for applications operating at sub-zero temperatures and involving volatile or toxic substances.

Our range of Stainless Steel Spectacle Blind Plate Flanges meets the diverse needs of various industries and is well-suited for high-pressure environments and extreme cold or hot temperatures. D J Metal provides the latest technological advancements and maintains a well-stocked inventory, ensuring prompt delivery to any location.

Stainless Steel Spectacle Blinds are commonly used to isolate pipe systems or connect them. This type of flange involves a steel plate that is cut into two discs of specific thickness. These two discs are connected by a steel section, resembling the nose piece of a pair of glasses. One disc is a solid plate, while the other is a ring with an inside diameter matching that of a flange.

What are Stainless Steel Spectacle Blind Flanges?

Stainless Steel Spectacle Blind Flanges are specialized components designed for use in piping systems.

The key features of Stainless Steel Spectacle Blind Flanges include:

1. Dual Component Design: Comprising a solid circular plate and a ring, these flanges are configured in the shape of a pair of eyeglasses, providing distinct components for sealing or opening the pipeline.
2. Material: Typically constructed from Stainless Steel, chosen for its corrosion resistance, strength, and durability.
3. Versatility: Suitable for a wide range of applications due to their ability to withstand high-pressure environments and operate effectively in various temperature conditions.
4. Isolation Function: Primarily used for isolating or separating sections of a pipeline, preventing fluid flow when needed and allowing it when required.
5. Visual Indicator: The distinctive design serves as a visual indicator, making it easy to identify the position of the flange—whether the pipeline is open or closed.
6. Ease of Operation: The rotational nature of the flange allows for easy opening and closing, facilitating efficient control of fluid flow.
7. Applications in Maintenance: Commonly employed during maintenance or inspection activities to seal off specific sections of the pipeline and prevent leakages.
8. Industry Standards: Manufactured in adherence to industry standards such as ASME B16.5, ensuring uniformity and compatibility with other components in the piping system.
9. Leak Prevention: The solid plate component provides an effective seal, minimizing the risk of leaks during pipeline closure.
10. Resistance to Corrosion: Stainless Steel’s corrosion resistance properties enhance the longevity and reliability of these flanges, even in challenging environments.
11. Figure 8 Shape: Sometimes referred to as “figure 8” flanges due to their characteristic shape.

The key features of Stainless Steel Spectacle Blind Flanges include their dual-component design, material composition, versatility, isolation function, visual indicator, ease of operation, applications in maintenance, adherence to industry standards, leak prevention, resistance to corrosion, and their distinctive “figure 8” shape. These features collectively contribute to their effectiveness in managing fluid flow and ensuring the integrity of piping systems.
