Enhance Your Piping Solutions: From Standard to Custom Flanges

As we navigate the evolving landscape of industrial infrastructure, the flange market has witnessed remarkable growth, valued at USD 6.07 Billion in 2023 and projected to double by 2036. This surge is driven by the persistent demand for energy and robust infrastructure development

These flanges are vital in piping systems, enabling safe and effective transfer of gasses and fluids. While standard flanges adhere to stringent national and international standards, ensuring consistency and reliability, the dynamic needs of modern industries often necessitate custom flanges. These bespoke solutions cater to non-standard specifications, offering unparalleled compatibility and performance in specialized settings.

What is a Custom Flange?

Custom flanges represent the pinnacle of tailored engineering. They are meticulously designed to meet unique industrial demands that standard flanges cannot accommodate. These bespoke components ensure seamless integration and optimal performance across specialized applications.

At Texas Flange, we believe in pushing the boundaries of engineering excellence. Our custom flanges are not just components; they are the epitome of innovation and precision, crafted to meet the unique demands of our dynamic industries.

Specially designed and customized flanges for specific projects can meet the same quality, inspection criteria, and performance standards as standard industry flanges. Providing a unique size, material, pressure ratings, and other fitting-specific purposes.

Need for Custom Flanges

Industrial production environments often have specific requirements that standard flanges cannot meet. Custom flanges address these needs by providing tailored solutions that ensure proper fit and function.

Some sectors, such as oil and gas, power generation, and chemical processing, may require flanges that are either bigger or smaller than the standard sizes commonly available. A specialized flange that links an unusual pipe size or supports a double bolt layout is an example.

Types of Flanges

Imagine a world where every industrial challenge is met with a precise, custom-engineered solution. At Texas Flange, we make this vision a reality with our diverse range of custom flanges, each designed to meet your specific needs.

1. Slip-on Flanges:

These are intended to slide onto the pipe’s end with a snug fit. They are commonly utilized in low-pressure scenarios. To avoid leaks, both internal and external welds are necessary. They are available in standard and reduced sizes, as well as ring and hub styles.

2. Lap Joint Flanges:

These flanges, also known as Backup flanges or Loose Ring Flanges, come in various sizes for connection and are designed to be used with stub end fittings. They are perfect for situations where regular disassembly is needed for examination or cleaning.

3. Weld Neck Flanges:

This is a flanges segment with one of the most significant opportunities for growth. These are recognized for their elongated, converging hub, which makes them suitable for high-pressure uses and offers additional support to the flange.

4. Blind Flanges:

These flanges are employed to end piping systems and are beneficial for checking and maintaining systems. They can also seal pipes and containers.

5. Threaded Flanges:

These flanges are designed to fit pipes with external threads. Utilized in situations where welding is not feasible, a threaded flange is best for high-pressure piping of small diameter.

6. Socket-Weld Flanges:

These are utilized for small high-pressure pipes and are created with a socket connection and upper weld. For optimum internal flow, the pipe must be inserted into the socket end before welding.

7. Specialized Custom Flanges:

Custom flanges can be further specialized based on specific needs:

a) Weldoflange:

A combination of a butt-weld flange and a branch-fitting connection made from a single piece of solid forged steel.

b) Nipoflange:

A branch pipe inclined at an angle of 90 degrees, combining a butt-weld flange and a forged Nipolet.

c) Elboflange and Latroflange:

Combinations of flanges with Elbolet and Latrolet are used to branch pipes at specific angles.

d) Swivel Ring Flange:

This flange facilitates the alignment of bolt holes between mating flanges, making it ideal for large-diameter pipelines and subsea applications.

e) Expansion Flange:

This is used to increase the aperture of a pipe at a specific point, connecting to mechanical equipment like pumps and valves.

f) Reducer Flange:

Opposite the expansion flanges, which are used to reduce the bore diameter of the pipe.

How We Make Custom Flanges?

Design Considerations

From customer needs, a unique flange is designed. The chosen metal is shaped by a machine or powerful press. Holes are drilled, surfaces are finished, and everything is checked for perfection. Finally, documented and shipped, the custom flange is ready to solve a specific piping challenge.

Designing a custom flange requires understanding several key factors:

1. Type of Flange:

The specific type needed for the application.

2. Size:

Accurate dimensions to ensure proper fit and function.

3. Pressure Rating:

The flange must withstand the operational pressure of the system.

4. Flange Face Type:

The surface configuration that will come into contact with the gasket and mating flange.

Manufacturing Process

The process of manufacturing custom flanges at Texas involves several steps:

1. Selection of material:

Pipe flanges can be custom-made using various materials and grades. Plates and forged materials, along with titanium and aluminum, are frequently used for lighter tasks. At Texas Flanges, we use a variety of materials to fulfill our project requirements, such as:

a) Aluminum Range:

A2011, A2024, A2017, A5052, A5056, A6061, A6063, A6463, A6082, A7075 are all types of aluminum alloys.

b) Copper Range:

3600, 3604, and 3771.

c) Plastic Series:

Delrin, POM, Lexan, Nylon 66, Nylon 6, PEEK, PP, PE, Acetal.

d) Rubber Series:

EPDM, neoprene, buna-n, and Viton are types of rubber materials.

e) Titanium Range:

Grade levels 1 through 28.

f) Steel Series:

a105, a36, a516–70, and A572–50, as well as other variants of carbon steel.

2. Forging:

Shaping the flange through the forging process using the chosen material creates a denser grain structure in the metal. This process improves strength, but it may be limited in design complexity.

3. Machining:

Achieving specific dimensions and surface finish through computer-controlled machines to cut and shape the flange from a solid block of material. It is highly recommended for complex shapes or tight tolerances.

4. Heat Treatment:

Applying stress relieving and additional heat treatments to improve the mechanical characteristics of the flange.

5. Finishing and Quality Control:

Once the flange is formed, holes are drilled, threads are tapped, and sealing surfaces are created if required. Later, rigorous testing ensures the flange complies with all defined standards and requirements.

Flange Face Types

The flange face type is crucial for ensuring a proper seal:

1. Flat Face (FF):

The gasket is in complete contact with the entire face, commonly found in applications with low pressure.

2. Raised Face (RF):

The gasket is positioned on an elevated flange section, enhancing the sealing pressure.

3. A Ring Joint (RTJ):

It utilizes a metal ring gasket, which is perfect for applications requiring high pressure and high temperature.

4. Tongue and Groove (T&G):

One flange features an elevated ring (tongue), while the other has a corresponding groove.

5. Male and Female (M&F):

This type is similar to the T&G Face type, but it has varying profiles to align with the gasket.

Flange Finishes

The surface finish of the flange face affects the sealing performance. Common finishes include:

1. Stock Finish:

A standard finish produced by a turning tool.

2. Concentric Serrations:

Fine grooves that enhance the grip of the gasket.

3. Spiral Serrations:

Continuous spiral grooves that provide a strong seal.

4. Smooth Finish:

A smooth surface finish used with soft gaskets.

Flange Pressure Ratings

Flanges are rated based on their ability to withstand pressure at different temperatures. Standard pressure ratings include:

1. Class 150:

Suitable for low-pressure systems.

2. Class 300:

Used in moderate-pressure systems.

3. Class 600:

Suitable for higher-pressure systems.

4. Class 900:

Used in high-pressure systems.

5. Class 1500:

For very high-pressure applications.

6. Class 2500:

The highest pressure rating for extreme conditions.
