Frequently Asked Questions

 

 

What is a carbon steel flange?

A carbon steel flange is a forged or cast ring used to connect pipes, valves, pumps, or other equipment in a piping system, made from carbon steel for its strength and durability. These flanges provide a secure connection and can be bolted or welded to the pipe, ensuring a tight seal for high-pressure applications. Carbon steel flanges are commonly used in industries such as petrochemical, oil and gas, and power generation due to their ability to withstand high temperatures and pressures.

 

What are the grades of carbon steel flanges?

The grades of carbon steel flanges are typically classified based on their material composition and mechanical properties, with common grades including ASTM A105, ASTM A350 LF2, and ASTM A694. ASTM A105 is the most commonly used grade, suitable for high-temperature and pressure applications, while ASTM A350 LF2 is designed for low-temperature environments. ASTM A694 covers high-strength carbon steel flanges, often used in high-pressure transmission services like oil and gas pipelines.

 

What are carbon steel fittings used for?

Carbon steel fittings are used to connect and modify the flow in pipelines, ensuring a strong, durable, and reliable connection in systems that handle fluids or gases. These fittings, such as elbows, tees, and reducers, are commonly used in industries like oil and gas, petrochemical, and power generation, where high pressure and temperature resistance are essential. Their strength, versatility, and resistance to wear make them ideal for both industrial and high-performance applications.
