Stainless Steel Blind Flange

Stainless steel blind flanges offer excellent corrosion resistance, high strength, and durability. Their solid, no-opening design ensures a secure seal, making them ideal for use in chemical processing, oil and gas, and water treatment. They are easy to install, maintain, and come in various specifications and pressure ratings per standards like ASME, EN, and DIN.

High Quality Stainless steel blind flanges

SSM manufactures stainless steel blind flanges, which are solid disk-shaped components used to close off the ends of pipes, valves, or pressure vessel openings. Unlike other flanges, they lack a central opening, making them ideal for stopping the flow of fluids or gases within the pipeline.

We choose stainless steel for its excellent corrosion resistance, strength, and durability, making these blind flanges suitable for various applications, including chemical processing, water treatment, and the oil and gas industry.

Stainless Steel 304 Blind Flange

SSM produces Stainless Steel 304 blind flanges that offer excellent corrosion resistance, high strength, and good weldability. These flanges effectively seal the ends of pipes or vessels, preventing leaks and providing reliable sealing under various chemical and environmental conditions. The 304 stainless steel material ensures resistance to oxidation and high temperatures while also delivering an attractive appearance with its smooth surface. They are suitable for use in industries such as chemical, petrochemical, and food processing.

Stainless Steel 316 Blind Flange

Stainless Steel 316 Blind Flanges are used to seal the ends of pipes or vessels and are made from 316 stainless steel. This material provides superior corrosion resistance, particularly against chlorides and saltwater, making it suitable for harsher environmental conditions compared to 304 stainless steel. They are commonly used in chemical processing, marine engineering, and high-temperature applications, offering strong and reliable seals while delivering excellent high-temperature performance and oxidation resistance.

150# Stainless Steel Blind Flange

SSM produces 150# Stainless Steel Blind Flanges that, according to ASME B16.5 standards, are designed for a pressure rating of 150 pounds. These flanges are typically made from 304 or 316 stainless steel. The ASME B16.5 standard specifies the dimensions, pressure ratings, and material requirements to ensure reliability under standard temperature and pressure conditions. The 150# rating indicates that these flanges can withstand a maximum working pressure of 150 pounds per square inch (psi). Below are the dimensions of this flange, which we hope will assist you with your procurement.
