Introduction
In piping systems, every component plays a crucial role in ensuring safe and efficient operation. One such essential component is the carbon steel blind flange. Unlike other flanges, a blind flange does not have an opening for fluids to pass through. Instead, it acts as a solid barrier to close the end of a pipe or nozzle. This makes it vital in applications where isolation, testing, or maintenance is required.
Fortis Forge, a trusted supplier of high-quality industrial fittings, provides durable carbon steel blind flanges that meet global standards. Choosing the right blind flange ensures operational safety, cost-efficiency, and compliance with industry requirements.
What is a carbon steel blind flange?
A carbon steel blind flange is a type of flange designed without a bore. It is used to seal the end of a pipe, valve, or vessel opening. Its strong build ensures that no fluid or gas passes through, making it essential for shutting down sections of piping or testing pressure levels.
Carbon steel is preferred for blind flanges due to its strength, durability, and resistance to high pressure. It also offers affordability compared to stainless steel or alloy alternatives
