AWWA c207 international standard and slip on hubbed flange under this standard

The AWWA C207 standard was developed by the American Water Works Association (AWWA) and is mainly aimed at standard specifications for flange connection components in municipal water supply and sewerage systems. The full name of this standard is “AWWA C207 – Steel Pipe Flanges for Waterworks Service – Sizes 4 In. Through 144 In. (100 mm Through 3,600 mm)”.

Under AWWA C207 standard, Slip-On  Flange is a common flange type used to connect pipes, valves, pumps and other piping equipment. Here is some information about necked flat weld flanges per AWWA C207 standard:

Slip-On hubbed flange is a flange that usually has a flat flange face and is used for flat welding connections with pipes. It also has a threaded neck section for connecting to a threaded flange. The neck length of necked flanges often varies as needed to meet specific pipe connection requirements.

Size Range:

The AWWA C207 standard specifies necked flat weld flanges in sizes ranging from 4 in. (100 mm) to 144 in. (3,600 mm) for a variety of pipe diameters.

Pressure Class:

According to AWWA C207 standard, necked flat weld flanges are usually divided into different pressure classes to accommodate different working pressure requirements. Different pressure levels are suitable for different applications and engineering projects.

Material:

Slip-On hubbed Flange is usually made of carbon steel, stainless steel or other suitable metal materials to adapt to different working environments and media. Material selection will be based on specific project requirements and application conditions of the piping system.

Design requirements:

AWWA C207 standard includes design requirements for slip on hubbed flanges such as dimensions, tolerances, threads, and tapped holes. These requirements help ensure flange performance and reliability during installation and use.

Application areas:

Slip-On hubbed Flanges are commonly used in municipal water supply and sewerage pipeline systems, including municipal water supply, industrial water supply, water treatment and wastewater treatment and other applications. They are used to connect pipes, valves, pumps and other piping equipment to ensure the reliability and safety of the piping system.

In summary, necked flat weld flanges are a common flange type that conforms to AWWA C207 standards and are widely used in municipal water and wastewater projects. This flange connects pipes through flat welding and has a neck for threaded connection, which can be applied to various pipe diameters and working pressure levels. The selection of necked flat weld flanges should be considered based on specific project needs and piping system design requirements.
