ASME B16.47 Flange
View ANSI B16.47 Slip On Flange, ASME B16.47 Blind Flange Dimensions.
ASME B16.47 Flange is made under the ASME B16.47 which covers larger diameter flanges ranging from 26 inches to 60 inches in diameter. R.C. Metal Corporation is a leading manufacturer and supplier of the ANSI B16.47 Slip On Flanges and other types of flanges in this standard. The slip on flanges are good to use with seamless pipes and precision measurements because they allow the pipes to slip onto them. The ASME B16.47 Blind Flanges is a special type of flanges because it does not extend the pipe line but closes it. It is used mostly in maintenance systems. There are different types of flanges such as the Lap joint flange ASME B16.47 and others.
ASME B16.47 Flange
The types vary in manufacturing such as the forged, screwed and threaded flanges. And the types vary in faces such as the flat face, raised face and the ring type joint flanges. The B16.47 slip on flanges is less common in applications. The rtj is also less common but it is used for maximum welding strength and tighter connection. The Welding neck flange ASME B16.47 has a neck form welded onto the flanges. This allows the pipes to be held together with the flange while and after welding. The ANSI B16.47 lap joint flanges has a lap joint on it which is mostly used along with stub ends.
The lap joint is then free to rotate around the stub. These are used mostly in applications which need frequent dismantling of the connection. The Weld neck flange b16.47 comes in different classes and pressure numbers. The classes range from 75 to 900 for this particular standard. There are different types such as the B16.47 Reducing flanges which reduces the pipe diameter at the connection. The functionality of each type differs and it is important for different connection type and application types. The ASME B16.47 RTJ flanges as well as other flanges are made by us with higher quality. Please feel free to contact us for a complete catalog of WN Flange ASME b16.47 and the price list.
