ASTM A182 / ASME SA182 F60 UNS32205 Slip On Flanges Duplex Steel Flanges B16.5
ASTM A182 F60 Flanges Definition
ASTM A182 F60 Slip On Flange is a type of flange used in piping systems, particularly in high-pressure and high-temperature applications.
- Hubbed design provides strength and stability
- Welding on both sides creates a strong joint
- Suitable for moderate pressure applications
Used in petrochemical, chemical, power generation, and other industries requiring corrosion resistance. Suitable for steam, water, oil, and mild chemical services.
What is the difference between F60 and other alloy steel grades?
It has excellent corrosion resistance and strength characteristics, better local corrosion resistance, and is widely used as a material for chemical equipment. Compared with 316L and 317L austenitic stainless steel, 2205 alloy is superior in resistance to pitting corrosion and corrosion. It has high corrosion resistance. Compared with austenite, it has a lower thermal expansion coefficient and higher thermal conductivity.
What are the Uses of Alloy Steel A182 F60 Flanges?
Designed to slip onto the end of a pipe and be welded both inside and outside to hold it in place.
What is the temperature range of Alloy Steel A182 F60 Flanges?
UNS S31803/S32205 heat treatment process: The solution treatment temperature is 1020~1100℃, and rapid cooling is required after heat treatment. The cooling speed should be as fast as possible, and the time exposed to the brittle temperature range (475℃ brittle temperature range, 0 brittle temperature range) must be shortened.
