If you’re in the business of manufacturing or supplying piping systems, then you’re likely familiar with ASTM flanges. But what are they? And more importantly, how can they help your business?

ASTM flanges are a specific type of flange that is used in a variety of industries. They can be made from different materials, and come in a variety of sizes.

In this post, we’ll answer all those questions and more. So, if you’re curious about ASTM flanges, read on!

1. ASTM Flange Specifications

ASTM flange specifications define the dimensional requirements for flanges made from different stainless steel materials. They also include requirements for gaskets, bolts, and nuts.

There are a variety of ASTM flange material specifications, each tailored to a specific material or application. Some of the most common ASTM flange specifications include:

ASTM A105	For carbon steel flange material
A350	For alloy steel flange materials
B16.5	For pipe flanges up to 24″ diameter
B16.47	For large diameter pipe flanges
M SS SP44	For stainless steel flanges
ASTM A350 LF2	For low-pressure and high-temperature applications
ASTM A694 F42	For high-pressure and high-temperature applications

When selecting an ASTM flange specification, it’s important to consider the material and dimensions of the flange. You also need to make sure the specification is compliant with any applicable codes and standards.

2. ASTM Flange Standards

ASTM flange standards are important for ensuring that flanges manufactured to these specifications meet the required tolerances and dimensions. This facilitates the interchangeability of parts and minimizes the need for re-design and re-manufacturing of parts.

There are several different ASTM flange standards, each covering a range of flange sizes and ratings. Some of the more commonly used standards include:

ASTM A105

ASTM flange material A105 covers carbon steel flanges up to 900 psi.

ASTM A350

Covers carbon, nickel alloy grades, and stainless steel flanges for high-pressure and high-temperature applications.

ASTM A182

Covers alloy steel forged flanges for high-pressure and high-temperature applications.

ASTM A694

Covers carbon and alloy forged steel flanges for high-pressure pipeline components.

ASTM F1136

Covers low-temperature carbon steel, and extremely corrosion-resistant alloy ASTM flange standards up to 2500 lb nominal pressure.

Therefore, it is important to select the appropriate ASTM flange standard when specifying a flange. This will ensure that the parts are manufactured to the correct specifications and that they meet the required performance criteria.

4. Types of ASTM Flanges

ASTM flanges are one of the most popular types of flanges. They come in a variety of sizes and shapes and can be used in a variety of applications. Some of the most common types of ASTM flanges include:

Blind Flanges

Blind flanges are used to seal off a pipe or opening. They have a hole in the center that allows fluid to flow through, and they are typically used in conjunction with a gasket to create a seal.

Lap Joint Flanges

Lap joint flanges are used to connect two pipes. They have a groove on the face of the flange that allows them to be attached to two pipes, and they are typically used with a gasket to create a seal.

Socket Weld Flanges

Socket weld flanges are used to connect two pipes. They have a socket on the face of the flange that allows them to be attached to two pipes, and they are typically used with a gasket to create a seal.

Slip-on Flanges

Slip-on flanges are used to connect two pipes. They have a groove on the face of the flange that allows them to be attached to two pipes, and they are typically used without a gasket.

Threaded Flanges

Threaded flanges are used to connect two pipes. They have threads on the face of the flange that allow them to be attached to two pipes, and they are typically used with a gasket to create a seal.

Weld Neck Flanges

Weld neck flanges are a type of ASTM flange that is used to connect two pipes. They have a weld neck joint that allows them to be attached to two pipes, and they are typically used with a gasket to create a seal.

Reducing Flanges

Reducing flanges are a type of ASTM flange that is used to connect two pipes. They have a reducing joint that allows them to be attached to two pipes, and they are typically used with a gasket to create a seal.

Each type of ASTM flange serves a different purpose, but they all have one thing in common they are used to connect pipes and other mechanical components. For more information contact us at Oflange.

5. Benefits of Using an ASTM Flange

An ASTM flange is a machined part that is used to connect two or more pieces of pipe or tubing. Flanges are available in a variety of sizes and materials, including high yield carbon steel, stainless steel, and aluminum.

There are several benefits to using an ASTM flange:

Strong and Durable

Astm flanges are designed to withstand high pressure and stress, making them ideal for use in heavy-duty applications.

Easy To Install

It’s easy to install ASTM flanges because they can be bolted together without welding. This saves time and money when installing new equipment or repairing existing systems.

Cost-Effective

An ASTM flange is a low-cost, durable option for industrial applications. The parts come in various sizes so you don’t have to worry about having the perfect fit.

Leak-Proof

Flanges are designed for a tight seal, making them leak-proof and ideal for use in critical applications.

Corrosion-Resistant

Astm flanges are made from corrosion-resistant materials, making them ideal for use in harsh environments.

For these reasons, ASTM flanges are a popular choice for many industrial applications. If you need a strong, durable, and leak-proof connection, an ASTM flange is a perfect solution.
