Types and Applications of Carbon Steel Flanges - United Forge

When purchasing Carbon Steel Flanges, it is important to consider factors to ensure you are getting the right product for your specific application. Some key things to keep in mind include the material used in the flanges and any additional features or specifications that may be important for your needs. Understanding these factors enables you to make an informed decision when buying ASTM A105 Carbon Steel Flanges.

Following are the Types of Carbon Steel Flanges

Slip-on Flanges

Slip-on flanges are flat or raised face flanges with a 1/16&#; lip. These flanges are good for pipe systems with low pressures and moderate temperatures. They can be easily welded into place and offer good corrosion resistance.

Slip On (SO) is the most basic and easiest flange type. This flange is welded into place after the installation, and its bore is slightly larger than the outside diameter of the connecting pipe. Its notable feature is that it has a recessed inside weld, which prevents damage to the flange&#;s face during the welding process.

A Slip-On flange isn&#;t just a good-looking piece of steel but also possesses a slew of valuable functions. For instance, the Socket Weld contraction ring is a clever device that resists corrosion. The ring is certified stainless steel and is designed to provide a pre-measured 1/16&#; gap, which is more than enough to meet most hydro-testing requirements.

Socket Weld Flanges

Socket weld flanges are a type of flange that connects two pipes. Their simple design makes them easy to install. In addition, they are very affordable. These flanges are easier to work with and great for welds under pressure.

There are many factors to consider when welding a flange. First, you must ensure that the flange will fit your piping. Next, you must decide which welding is best for your flange. For example, you should try TIG welding if it is a thin steel sheet. MIG welding might be a better option if it is a thicker material. These flanges have a tapered hub and a long tapered throat, allowing for a smooth transition from the flange to the pipe. They are typically used in high-pressure and high-temperature applications.

Threaded Flanges

These flanges have threads on the inside of the flange, allowing them to be screwed onto the pipe. They are typically used in low-pressure applications and are easy to install and remove.

A well-chosen flange is an invaluable asset if handled with care. A properly fitted and maintained flange is a veritable oasis for your most precious cargo.

Lap Joint Flanges

The lap joint flange is a two-component design commonly used for larger-diameter piping configurations. It can be made from different types of steel, including carbon steel. It is often used to help simplify the assembly and dismantling of large-diameter and stiff piping systems.

A lap joint flange is similar to a weld neck flange but features a stub end. The stub end has a weld bevel. Butt welding is used to attach the stub end to the pipe.

Lap joint flanges can be a great way to save money. However, they need to be better suited for high-pressure applications. They are often used for low alloy steel piping systems and applications requiring frequent disassembly.

Applications of Carbon Steel Flanges

ASTM A105 is a standard specification for carbon steel forgings, including flanges, fittings, valves, and other piping components for use in pressure systems at ambient and high-temperature service. ASTM A105 Carbon Steel Flanges are made from a type of carbon steel known as &#;killed steel&#; which means that the steel is fully deoxidized during the manufacturing process to prevent the formation of any gas holes during solidification.

ASTM A105 flanges are commonly used in high-temperature and high-pressure applications such as oil and gas, power generation, and chemical processing. They are also used in heavy-duty industrial applications such as in the construction of pipelines, power plants, and oil refineries.

Before purchasing, it is important to check the material&#;s chemical composition and mechanical properties. It should meet the requirement of ASTM A105 specifications and be inspected and tested by a third-party inspection agency.
