Flange

Pipe flanges are method of connecting pipes, valves, pumps and other equipment to form a piping system.

A figure-8 blank (also called a Spectacle Blind Flange) is+ a pressure-retaining plate with one solid end and one open end connected with a web or tie bar.

The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face.

Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used.

A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter.

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures.

The NW Long Weld Neck Flanges is normally referred to as the high hub flange.

The Slip-on flange has a low hub because the pipe slips into the flange prior to welding.

Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded.

The Welding neck flanges is normally referred to as the high hub flange.

ANSI Flange Standards

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors.

Flange materials acc. to ASTM

Dimensions from carbon steel and stainless steel flanges are defined in the ASME B16.5 standard. The material qualities for these flanges are defined in the ASTM standards.

At some point, with all the possibilities of thread form, diameter, and pitch, you need to send it off to SK Grimes or another machinist.

AWWA and Plate Steel Flanges General Information

American Water Works Association (AWWA) is an international non-profit, scientific and educational association founded to improve water quality and supply.

Flange types

As already described before, the most used flange types acc. to ASME B16.5 are: Welding Neck flange, Slip On flange, Socket Weld flange, Lap Joint flange, Threaded flange and Blind flange.

Understanding customers requirement and ensuring to supply as per these requirements is realised with the help of quality assurance at Sunny Steel one of the best Flange Manufacturers in China, our product range include all types of flanges such as MS Flange ( Mild Steel ) , Raised face flange , Weld neck flange, Bellow Flange , and Flanges according to custom requirement.

Flange Materials Specification

The usual materials of flanges include stainless steel, carbon steel, aluminum and plastic. The choice of the material largely depends on the purpose of the flange.
