ASTM A182 F91 Flange
View A182 F91 Socket Weld Pipe Fittings, Alloy Steel F91 Threaded Union Chemical Composition.
ASTM A182 F91 Flange is made up of a material that can be cold worked to harden. The most uses of the material is in general corrosive applications and R.C. Metal Corporation is a leading manufacturer of the Alloy Steel F91 Threaded Union, coupling, tee, bend and crosses in various dimensions. The fittings and flanges belong to the ASTM A182 specification for pressure vessel applications. The A182 F91 Socket Weld Pipe Fittings are welded with a socket that can hold small size pipes in place. There are different types such as the weld neck fittings and threaded fittings. The dimensions of the Alloy Steel F91 Forged Fittings range from ½ inches to 48 inches of nominal diameter and various wall thicknesses.
ASTM A182 F91 Flange
The wall thicknesses and the diameters account for various pressure classes ranging from 150 to 2500. The fittings such as the Alloy Steel 11/4 Cr-1/2Mo Threaded Plug are also labeled by pressure numbers starting from PN6 through PN64. The material has 8% chromium, molybdenum, manganese, carbon, silicon, sulfur and phosphorus in the composition. The different types such as the A182 F91 Cl2 Lap Joint Flanges are used in different application set ups. They are used in oil and gas, petroleum, petrochemical and many other industries.

. The Alloy steel A182 F91 flanges can also be raised faced, flat faced or ring type joint flanges. There are functional differences in the shapes of the flanges as well. The F91 Chrome moly SORF Flange has a raised face and is a slip on flange. The seamless pipes are used in precise applications and they sometimes need to be slipped onto the flanges for precise location. The A182 F91 Steel Slip On Flanges provide this advantage. Please contact us for more product information and pricing of the flanges and fittings.
