What is slip on flange?
Slip on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the back side of the flange.
What is class 125 flange?
1 Class 125 flange is rated for 125 psi at 353ºF (178ºC), which is the boiling temperature for water at that pressure. As temperature increases, the pressure rating of the flange decreases.
What is the difference between AWWA C110 and C153?
Description: Today, standard compact fittings C153 are commonly used in place of full Body fittings C110. They are designed to be to be more lightweight and more economical to use while providing better flow characteristics.
What is AWWA fitting?
AWWA size fittings are supplied with rigid radius grooves in accordance with ANSI/AWWA C-606. Fittings conform to ANSI 21.10/AWWA C-110 for center-to-end dimensions and AWWA C-153 or ANSI 21.10/AWWA C-110 for wall thicknesses. Available with a wide variety of coatings and linings.
What is the difference between RF and FF flange?
Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat. That means that the gasket used with the FF flange has full contact with the whole surface where two flanges are mated.
What is RF in flange?
The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.
What is the difference between class 125 and class 150 flange?
1 Class 125 flanges are made from cast iron, ANSI/ASME B16. 5 Class 150 can be made from steel or stainless and ANSI/ASME B16. 42 Class 150 is made from ductile iron. However, the bolting pattern is the same for both Class 125 and 150 so, regardless of material, they will bolt together.
