ASTM A182 F60 Duplex Stainless Steel Flange WNRF Forged Steel Flanges

Product Specification

ASTM A182 F60 Duplex Stainless Steel Flange WNRF Forged Steel Flanges

The material composition of ASTM A182 F60 flanges contains 3-3.5% molybdenum. This level has different pressure levels, ranging from CLASS 150 to 2500 LBS. YUHONG GROUP is the leading supplier and manufacturer of these f60 duplex stainless steel flanges in various sizes and shapes. Standards include ASME B16.47, B16.5 and B16.48, with diameters ranging from ½ inch to 48 inches. The pressure-bearing capacity of the flange is expressed in the JIS system from 5K to 63K, and in the EN and UNI system from 6Bar to 40Bar.

These can be forged, processed and heat treated. ASTM a182 F60 UNS S32205 BLRF flange is a blind raised face flange. Blind flanges are used to close the connection. The raised face supports additional connection space or accessory space. Flanges can be divided into flat type, raised surface type and ring type connection flange according to the surface type. The astm a182 gr f60 SORF flange is a sliding on the raised face flange, and the pipe can be slid to the correct connection point.

The melting point of the flange material is 1420 degrees Celsius. This allows the flange to operate at high temperatures. There is a welding neck on the A182 F60 welding neck flange, which can hold the pipe to the greatest extent during the welding process. The material has high fatigue strength and is easy to weld. Gaskets are used to fasten flanges and pipes together during welding. We can provide f60 duplex stainless steel sliding flanges and other products.

Manufacturing and Heat Treatment
ASTM A182 F60 flanges shall be manufactured by hot forging. The steel shall be forged as close as possible to the specified shape and dimensions of the flange. The optimum forging temperature should be controlled between 1100°C [2000°F] and 1150°C [2100°F]. If the forging temperature is higher than 1150°C [2100°F], the dimensional stability of the workpiece may be affected and the tendency to form scale increases above this temperature. If the forging temperature is much lower than 1100°C [2000°F], significant amounts of detrimental intermetallic phases may form, leading to cracking in the deformed area. After hot forging, ASTM A182 F60 flanges shall be solution treated at a temperature not lower than 1870°F [1020°C]. Flanges should be soaked at this temperature long enough to dissolve any intermetallic precipitates. After complete solution annealing, rapid quenching should be carried out.

Pitting resistance equivalent number
ASTM A182 F60 flanges have excellent resistance to pitting corrosion, especially in chloride containing solutions. The main elements that contribute to resistance to pitting corrosion are chromium (Cr), molybdenum (Mo) and nitrogen (N). Based on these elements, an index for comparing resistance to localized pitting corrosion was developed. This indicator is called Pitting Resistance Equivalent Number (PREN). PREN of ASTM A182 Gr. F60 is defined in weight percent using the following equation: PREN = Cr + 3.3Mo + 16N. The higher the PREN, the better the ASTM A182 F60 flange will perform in chloride environments.

The end face type of flange A182 F60 can also be different, such as flat, raised and ring joint flanges. Flat flanges have flat surfaces, which allows them to be used in narrow spaces, where raised flanges have many surfaces for bolting and welding connections. The ring flange is divided into two halves, which are welded to different pipe ends, and they are combined by welding to obtain the maximum seal.

Flanges are part of the piping system and are used inside or outside the pipeline. Many types of flanged pipes are commonly used in piping systems. Flanges are like bridges, connecting pipes or fittings, making the pipe a complete system. Flange is an indispensable part of connecting pipes.
Pipe fittings are parts used to install or repair pipelines or pipeline systems that transport liquid, gas, and solid materials. This work includes selecting and preparing pipes or pipes, connecting them together in various ways, and locating and fixing vulnerabilities.
