Designed with a long tapered hub for high pressure applications, this flange type is welded to the pipe, providing stress distribution and strength in pipelines handling steam, gas, or chemicals.
This type slides over the pipe and is welded both inside and outside for leak proof performance. It is used in low pressure fluid systems, especially in chemical and water treatment industries.
What are alloy steel flanges typically made of?
Alloy steel flanges are primarily composed of chromium, molybdenum, and other alloying elements that enhance mechanical properties, corrosion resistance, and performance in high-pressure applications.
Are alloy steel flanges suitable for high-temperature applications?
Yes, alloy steel flanges offer excellent heat resistance and are ideal for high-temperature environments, such as in refineries, boilers, and power plants.
What makes alloy steel flanges durable in harsh environments?
The presence of elements like chromium and molybdenum improves resistance to oxidation, corrosion, and thermal stress, making them long-lasting in chemically aggressive and high-stress conditions.
