Product Description
DESCRIPTION OF STEEL FLANGE
Flanges are key components in pipe connections, serving both sealing and pressure-bearing functions. They are widely used in numerous fields including petroleum, chemical, power, shipbuilding, pressure vessels, wastewater treatment, wind power generation, construction machinery, urban water supply and drainage, roads and bridges, boilers, and nuclear power.
The most commonly used manufacturing materials include carbon steel, stainless steel, alloy steel, and nickel-based alloy steel. Common standards include: ANSI/ASME, DIN, EN, JIS, GOST, and ISO.

FEATURES&ADVANTAGES
Why choose our flange?
Adaptability and Standardization:
1. Flanges adhere to a wide variety of connection standards (such as GB, ANSI, DIN, etc.), ensuring global interchangeability. Furthermore, the extensive range of available materials—including carbon steel, stainless steel, and alloy steel—enables them to withstand complex operating conditions, ranging from corrosive media to extreme temperatures.
1. Flanges adhere to a wide variety of connection standards (such as GB, ANSI, DIN, etc.), ensuring global interchangeability. Furthermore, the extensive range of available materials—including carbon steel, stainless steel, and alloy steel—enables them to withstand complex operating conditions, ranging from corrosive media to extreme temperatures.
2. High Sealing Integrity and Reliability
Flanges utilize bolted connections to generate powerful mechanical force, compressing the gasket to form a tight seal. This enables their reliable application in the conveyance of toxic, flammable, explosive, or high-value media—a performance that often surpasses that of many permanent joining methods. When paired with metal gaskets, they are even better equipped to handle high-temperature and high-pressure operating conditions.
