ASTM A182 Gr F91

A182 F91 Alloy Steel Flanges has high tensile strength, anti-corrosive, corrosive corrosion resistance and stress corrosion cracking.
F91 Alloy Steel Pipe Flanges are well suited for high-pressure and high temperature applications as it tends to offer improved resistance to corrosion as to compare to other standard carbon grade steel flanges.

A182 F91 Class 2 Flange is strong, tough and extremely ductile, which makes it durable and long lasting. It provides good oxidation resistance and good resistance to scaling in aqueous medium.
Chrome Moly Alloy A182 F91 Flanges is ideal for environments with an elevated temperature level. So it is useful in any industries or applications which operate equipment under high temperatures.

F91 A182 Blind Flanges are placed in between two open flanges, which stop the flow through a pipe. Many times this type of blockade is used when a new valve is being added or while adding another line onto an existing pipeline.

A182 F91 Cl2 Lap Joint Flanges are available in common dimensions like other types of flange which makes it easy to use alongside other piping components or to integrate them into existing piping systems.
ASTM A182 Gr F91 Flange is often used in combination or is mostly matched with the ASTM A335 alloy steel pipes.

ASTM A182 Grade F91 Flange is provided in customized and conventional flanges complying with various international products quality standard for services at severe temperature.

1cr-1/2mo AS A182 F91 Flanges are used for the closure of a line. It has a combination of carbon, silicon, manganese, chromium, phosphorus, and molybdenum in the composition.

A182 Gr F91 Threaded Flanges are often used for small diameter, high pressure requirements. It is with a hub which has published specifications that range from 1/2″ thru 24″. It is ideal for small diameter piping applications.

SA 182 Gr F91 Socket Weld Flanges are typically provided with a flat face, raised face, or RTJ facing. When a raised face is necessary for SA 182 Gr F91 socket weld pipe flanges, the standard height is 1/16" for it is under 400#.
ASME SA 182 Gr F91 Slip On Flanges are mainly used for fluids at low pressure or with little risk of leakage. It is very common to find these flanges today in firefighting water lines, cooling water lines, low-pressure compressed air lines, and process lines for substances such as oil, gas, steam, condenser etc.
