What is Series B Flange? Uses, Dimension and Properties

Series B flanges are a type of pipe connector commonly used in the oil and gas industry. They’re tough and durable, perfect for joining pipes in situations where there’s a lot of pressure. In this blog post, we’ll discuss how Series B flanges are used, what makes them strong, and the specific welding techniques needed for them.

What is Series B Flange?

Series B flange is a type of high-pressure flange used for pipe work in extreme environments. Often referred to as “reverse-angle” or “spacer” flanges, Series B allows the piping to be safely connected without the need for a gasket due to its angled sealing face. It is commonly used in oil and gas projects, cryogenic applications, and other industries requiring highly reliable connections in hazardous or extreme conditions. With its unmatched durability and leak-proof capabilities, the Series B flange provides peace of mind that no matter what environment a business may encounter its operations will never be disrupted.

Series B Flanges Uses

Series B flanges are primarily used in the oil and gas industry for connecting pipes. They can also attach valves or other equipment to a pipeline. Their strength makes them ideal for high-pressure applications, such as transporting natural gas or crude oil. Additionally, they can be used in applications involving chemical processing or water treatment.

Series B Flanges Properties

Series B flanges have several unique properties that make them well-suited for use in the oil and gas industry:

• They’re incredibly strong due to their construction; they’re made from forged steel which is highly resistant to corrosion and wear.
• Their design allows for easy installation and removal when necessary.
• Their pressure ratings render them suitable for the most demanding applications; certain Series B flanges are available in pressure classes ranging from 75 to 900.

Flange Thickness

The thickness of Series B flanges varies based on factors like size and pressure rating, typically specified in standards such as ASME B16.5 or EN 1092-1, ranging from 0.84 inches for smaller sizes to 2.38 inches for larger sizes.

Flange diameter

Series B flanges, following ASME B16.5 standards, have diameters that vary based on nominal pipe size (NPS), typically ranging from 1/2 inch to 24 inches.

Flange bolt circle

The bolt circle diameter for a Series B flange follows industry standards like ASME B16.5 and may vary depending on the flange’s size and pressure rating.

Flange bolt holes

Series B flange bolt holes follow ANSI B16.5 standards, with sizes ranging from 1/2 inch to 24 inches and patterns determined by pipe size, pressure class, and flange facing type.

Flange material

Series B flanges are typically made of cast iron, although other materials like carbon steel, stainless steel, and alloys may also be used.

Welding Techniques for Series B Flanges

When working with Series B flanges, it’s important to use the correct welding technique; if done incorrectly, it could result in poor welds or even damage to the welded material. Generally speaking, TIG welding is recommended for its high accuracy and versatility; it can be used on ferrous and non-ferrous metals. Additionally, it produces clean welds with minimal discolouration – perfect for projects involving aesthetics and function! It is also important to use quality filler material when welding your series b flange – this will ensure a strong, durable connection that will last!
