1. AWWA Flange Definition
An AWWA flange is a type of connector used in piping and plumbing systems. AWWA flanges are standardized and come in different classes. AWWA flanges are known for their durability and ease of use.
AWWA stands for the American Water Works Association. AWWA’s goal is to protect public health by providing safe drinking water worldwide.
AWWA created a standard for AWWA blind flanges, which ensures that each flange will fit with any other AWWA flange, regardless of the manufacturer. AWWA flanges are tested in AWWA testing facilities.
AWWA flange classes range from Class 150 to Class 300. AWWA flange classes are designated by a 3 digit number with the AWWA designation code in front of it. The AWWA blind flange designation code will have “W” for welded auxiliary connections body AWWA flanges, “C” is cast body AWWA flanges, or “S” for forged body AWWA flanges.
2. Different AWWA Class
AWWA flange class is an important designation when choosing AWWA flanges. AWWA flange classes indicate the type of material used for the body and face, the pressure limitations, and test requirements.
The different AWWA flange classes are:
The AWWA C100 standard specifies the AWWA flanges dimensions and tolerances for flanges made from cast iron, ductile iron, or steel. It also includes requirements for gaskets, bolts, and nuts. Flanges that meet the AWWA C100 standard are suitable for use in water and wastewater systems.
The AWWA S160 standard covers the manufacture of flanges and their use in waterworks service. This AWWA flange standard applies to forged steel flanges, malleable iron flanges, and ductile iron flanges.
It specifies the AWWA flange dimensions and tolerances for these flanges, as well as the test methods that should be used to verify their qualifications.
AWWA W350 is a flange material that is made of ductile iron. It is an AWWA class d flange often used in the water and wastewater industries, as well as in other industrial applications.
3. The Difference Between AWWA Flange and Other Flange Types
There are other types of flanges that are not AWWA flanges. AWWA flanges have a very specific definition that separates them from other plumbing flange types:
AWWA flanges are usually described as being made of cast alloy, forged steel, or welded steel.
With Different Class
AWWA c228 flange classes also vary compared to other types of pipe fittings, such as “J” (ASTM A105) or “F” (ASTM A350).
AWWA flanges are intended for use on potable water systems whereas other types of pipe fittings are not.
AWWA flange dimensions are different from other plumbing flange types, which have thickness requirements that vary based on the size. For example, AWWA S160 AWWA flanges must be no more than 1/2″ thick, AWWA W350 AWWA flanges are permitted up to 3/4″ thickness.
AWWA c207 class b flanges are intended for use with AWWA sanitary fittings. Other types of flanges, such as J-type flange, will not fit AWWA sanitary fittings.
4. AWWA Standards
AWWA flange standards are created by AWWA committees. AWWA standards focus on water quality, corrosion, pressure rating, and installation of AWWA flanges.
AWWA standards impact the design of AWWA flange manufacturing processes. For example, AWWA C700 has a 20 psi minimum yield strength requirement; this will impact the AWWA flange manufacturing process.
AWWA C700 flanges will be made of lower quality steel flanges than AWWA S160 flanges, which do not need to meet the 20 psi minimum yield strength requirement.
AWWA standards also impact the material specifications for AWWA flanges. For example, AWWA c207 class d standard flanges have a maximum carbon content of 0.25%. AWWA S160 AWWA flanges may be made of AISI 1045, whereas AWWA W350 AWWA flanges must be made of higher quality steel, AISI 1010 or better.
5. AWWA Flange Material
AWWA Flange Material is a commonly used material in the making of flanges. It is an alloy that is made up of steel and chromium. The alloy has a high resistance to corrosion and abrasion. AWWA flange material is also non-magnetic and has good machinability.
AWWA flange materials are mostly used in industries and mechanical workshops. AWWA Flanges typically consist of a resilient or soft material. AWWA Flange manufacturers mainly use two types of AWWA Flanges:
Alloy is a material that is made by combining two or more elements, at least one of which is a metal. The resulting material has different properties than the individual metals. There are many different types of alloys, each with its own advantages and disadvantages. Some alloys are stronger than steel, while others are more corrosion-resistant.
Chromium is the best material to use for AWWA flanges. However, when used properly it can provide a very strong and durable flange. Chromium is a chemical element with the symbol Cr and atomic number 24.
It is a hard, silvery metal that takes a high polish. It is found in several ores, including chromite, and is used to produce stainless steel and other alloys.
6. AWWA Flange Dimensions
When it comes to flanges, AWWA has a few different dimensions that they follow. There are three standard flange classes which are Class 150, Class 300, and Class 600. The dimensions for these classes are as follows:
The inside diameters of the flanges range from 2 1/2″ to 24″. The thickness of the flange ranges from 3/8″ to 2″. The bolts are 1 1/4″ to 6″.
The inside diameters of the ring flanges range from 2 1/2″ to 24″. The thickness of the flange ranges from 3/8″ to 2″. The bolts are 1 1/4″ to 8″.
The inside diameters of the flanges range from 2 1/2″ to 48″. The thickness of the flange ranges from 3/8″ to 4.5″. The bolts are 1 1/4″ to 12.”
The AWWA standard also states that these dimensions are not for imperial flanges, such as those found in the United Kingdom or Canada. AWWA flanges will either be marked AWWA or AWWA USA.
|Class 150||The inside diameters of the flanges range from 2 1/2″ to 24″. The thickness of the flange ranges from 3/8″ to 2″. The bolts are 1 1/4″ to 6″.|
