SS 316 ASME B16.48 150# 30″ Spade Blind Flange
A Spade Blind Flange is mainly used for temporarily closing a pipeline, ensuring that the medium inside the pipeline does not leak during maintenance, inspection, or replacement. It is typically used together with a Spacer, allowing the flange to be inserted or removed during pipeline operations.
High Quality SS 316 ASME B16.48 150# 30" Spade Blind Flange
SSM provides the SS 316 ASME B16.48 150# 30″ Spade Blind Flange, made of 316 stainless steel and compliant with ASME B16.48 standards. It suits pipeline systems with a pressure rating of 150 pounds (150#) and a diameter of 30 inches.
- Standard: ASME B16.48
- Diameter: 30″ (30 inches)
- Pressure Rating: 150# (150 pounds per square inch)
- Material: SS 316 stainless steel
- Thickness: Varies according to pipeline and application standards
- Facing: Typically comes with Flat Face (FF) or Raised Face (RF) designs
Features
Blind Flange Design: Designed for temporary closure or isolation of pipelines, making it ideal for use during system inspections or maintenance.
Easy to Install/Remove: The spade design allows for easy installation and removal without the need to fully dismantle the pipeline.
Applications
- Oil and Gas Industry: Temporarily shutting off pipeline systems during maintenance, cleaning, or inspection.
- Chemical Processing: Used to isolate sections of pipelines carrying corrosive liquids or gases, preventing leaks.
- Power and Energy Industry: Used as a safety isolation device in high-temperature and high-pressure pipeline systems.
- Marine Engineering: Provides excellent corrosion resistance in saline environments, suitable for pipeline isolation on offshore platforms and ships.
Advantages and Disadvantages
The SS 316 ASME B16.48 150# 30″ Spade Blind Flange offers excellent corrosion resistance and high strength, making it ideal for chemical and marine environments. It is easy to operate and maintain, with a standardized design, widely used in industries like oil, chemical, and energy.
However, due to the higher cost of 316 stainless steel, the large size (30 inches) of the flange can make it heavier and more challenging to install. Additionally, the 150# pressure rating limits its use in extremely high-pressure applications, and regular maintenance is required to ensure its performance.

FAQ
A Spade Blind Flange is a device used to temporarily block the flow of fluids in a pipeline, primarily used during maintenance or inspection to isolate the medium inside the pipeline.
Due to its corrosion resistance, 316 stainless steel is particularly suitable for marine, chemical processing, and food processing environments, where high temperatures and resistance to corrosion are required.
150# refers to the pressure rating of the flange, meaning the maximum working pressure it can withstand is 150 pounds per square inch (psi).
A Spade is used to close the pipeline, while a Spacer is used to keep the pipeline open. They are usually used together, allowing easy switching between different operating states of the pipeline.
Regular inspections of the flange’s sealing are required, especially in corrosive environments. If any damage or corrosion is found, the flange should be replaced or repaired promptly.
