Carbon Steel Blind Flange

As a leading manufacturer and supplier, we specialize in carbon steel blind flanges. These essential components secure piping systems, connecting pipes, valves, pumps, and other equipment. Our flanges ensure a leak-proof and reliable connection.

Carbon steel is chosen for its strength, durability, and cost-effectiveness. It's a staple in diverse industries, including oil and gas, chemical processing, and power generation.

Blind Flange Dimensions:

We adhere to ASME B16.5 for sizes NPS ½” to 24”. For larger diameters, NPS 26” to 60”, our flanges meet ASME B16.47 standards.

ASTM A105N (SA105N) Carbon Steel Blind Flanges:

Our flanges are crafted from ASTM A105 forged carbon steel. This mild carbon steel is ideal for both ambient and high-temperature pressure systems. It offers excellent durability and is highly resistant to breakage. For stainless steel piping, a lap joint end ring ensures perfect compatibility.

Relevant Standards: We comply with key industry standards:

* B16.5: Dimensional standards for steel pipe flanges.
* B16.34: Standards for flanged, threaded, and welded end valves.
* B16.47: Standards for large diameter steel flanges.
* SP44: Steel pipeline flange specifications.
* API 605: Standards for large diameter carbon steel flanges.

Coating Options:

To protect against rust and corrosion, we offer several coating types:
* Anti-rust painting
* Oil varnish
* Electric zinc coating (white or yellow)
* Alloy material coating (lined or clad)

Applications of Carbon Steel Blind Flanges:

Our flanges are widely used across various critical applications:
* **Piping Systems:** Essential for water, oil, and gas pipelines, connecting vital components.
* **Pressure Vessels:** Key in oil and gas, chemical, and power generation sectors.
* **Marine Engineering:** Built to withstand harsh marine environments.
* **Manufacturing Equipment:** Found in pump manufacturing, petrochemical, and nuclear power facilities.

Their robust nature and adaptability make our carbon steel flanges indispensable in numerous industrial settings.
