What is the difference between AWWA C207 and C228?
The AWWA standard only encompasses ring, hub and blind flanges. The ANSI standard includes all flange types as well as welded auxiliary connections and tapping. There are currently 180 standards covered by the AWWA, C207 for carbon steel flanges and C228 for stainless steel flanges.
AWWA C207 and AWWA C228 are both standards established by the American Water Works Association (AWWA) but focus on different aspects of waterworks equipment:
AWWA C207:
– Purpose: AWWA C207 specifies the dimensions, pressure ratings, materials, and methods of manufacture for steel pipe flanges for waterworks service in sizes 4 inches through 144 inches. It includes various types of flanges, such as slip-on, blind, threaded, and welding neck flanges.
– Application: This standard is specifically concerned with steel pipe flanges used in water supply service, including potable water, wastewater, and other water-related applications.
AWWA C228:
– Purpose: AWWA C228 addresses the stainless-steel pipe flanges used in water service. It covers the dimensions and tolerances for stainless-steel flanges in sizes 2 inches to 72 inches. This standard focuses specifically on stainless steel and its application in waterworks systems.
– Application: AWWA C228 is concerned with stainless-steel flanges specifically for water service, ensuring these components meet the necessary requirements for use in water supply systems.
Key Differences:
1. Scope: AWWA C207 covers a broader range of materials and sizes for steel pipe flanges used in waterworks service, while AWWA C228 specifically deals with stainless-steel flanges within a specific size range for water service applications.
2. Material Focus: AWWA C207 covers various materials used in flanges for waterworks applications, while AWWA C228 specifically focuses on stainless steel.
In summary, AWWA C207 is a more general standard that encompasses a wider range of materials and sizes for steel pipe flanges used in waterworks, whereas AWWA C228 is specifically focused on stainless-steel flanges within a defined size range for water service applications.
