Product Information

Standards & Materials: ASTM A182 F5

ASTM A182 F5 flanges shall be manufactured by a forging process furnished in Class 75, 150, 300, 400, 600, 900, 1500, 2500 in accordance with ASME B16.5 and ASME B16.47 (Series A & Series B). Grade F5 of ASTM A182 is a typical Cr-Mo heat resistant alloy steel with nominal chemical composition of 5Cr-0.5Mo and UNS number of K41545.

Mechanical Properties of ASTM A182 F5 Alloy Flanges

Flange Type: Slip On (SO)

Slip on flange also simplified as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom. It is used to insert the pipe into the inner hole of flange, as the flange inner diameter is little bigger than the pipe’s outer diameter, pipe and flange could be connected by lap welding at the top and bottom of the flange.

The slip on flange is shorter in length than a weld neck flange, and is used in areas where short tie-ins are necessary or space limitations necessitate its use. Generally, the life span of a slip-on flange connection is about one-third that of the weld neck flange. Despite of additional welding involved during installation, its lower initial cost makes the SO flange preferred over WN flanges by many users. It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering.

Pressure-Temperature Ratings

Both ASME B16.5 and ASME B16.47 has stipulated pressure-temperature ratings for ASTM A182 F5 steel, which are maximum allowable working gauge pressures in psi units at the temperature in degrees Fahrenheit. The data sheet is divided by Classes: ASME B16.5 flanges are available in Class 150, 300, 400, 600, 900, 1500, 2500; ASME B16.47 Series A are available in Classes 150, 300, 400, 600, 900; and ASME B16.47 Series B are available in Classes 75, 150, 300, 400, 600, 900.
