DIN ANSI Carbon Steel Forged Blind Flange

DIN / ANSI Carbon Steel Forged Blind Flange – High-Quality Flanges by SSM

SSM supplies premium-quality DIN / ANSI Carbon Steel Forged Blind Flanges designed for high-performance sealing and isolation in pressure piping systems. Manufactured in compliance with international standards, these blind flanges are ideal for applications requiring strong, durable, and leak-proof terminations.

What is a Forged Blind Flange?

A Blind Flange is a solid disk used to seal the end of a pipeline, valve, or pressure vessel. Unlike other flanges, it has no bore (no center hole), allowing it to stop the flow in a piping system.
When manufactured by forging, the material's grain structure becomes more compact, improving the strength, toughness, and resistance to pressure compared to cast or machined alternatives.

Standards and Pressure Ratings

SSM provides Blind Flanges according to both DIN (European) and ANSI / ASME B16.5 (American) standards.
Available pressure classes include:

ANSI Class 150, 300, 600, 900, 1500, 2500

DIN PN10, PN16, PN25, PN40

Material Grades

Our Carbon Steel Forged Blind Flanges are manufactured using top-quality materials such as:

ASTM A105 / A105N – For general service at ambient and higher temperatures

ASTM A350 LF2 – For low-temperature service applications

ASTM A694 F42–F70 – For high-yield strength pipeline systems

Each flange undergoes heat treatment, ultrasonic testing, and dimensional inspection to ensure quality and compliance with customer specifications.
