Advantages Of Using Stainless Steel Flange Fittings

Did you know the first-ever hydrocarbon type pipeline was believed to be bamboo, used in China around 500 BC? After that, technology evolved gradually and then rapidly, and the U.S. built the first wooden oil pipeline in 1862 in Oil Creek Valley, Pennsylvania. Utilizing modern steels and alloys, around 2.6 million miles of oil and gas pipelines are across the country today.


Manufacturers use a wide variety of materials for oil and gas pipelines than you can determine from just viewing operations in the field. Most steel alloys look stainless or are painted for field service. The selection of the correct material grade depends entirely on the application types, uses, size, and environmental requirements.

Pipeline materials include, plastics/polymers, cast and forged carbon, low and medium chrome, nickel alloys, and various grades of stainless steel. Aside from carbon, stainless steel flanges are the most common and offer numerous benefits for oil rigs and piping systems.

Let’s dive in!

Benefits of Using Stainless Steel Flange Fittings

1. Corrosion Resistance 

Liquid and gas flow through the oil pipelines continuously, which causes corrosion in the piping system. Corrosion is the primary concern in the oil and gas industry. It is estimated to cost the U.S. economy around $9 billion annually.

Stainless steel selection helps rescue energy industry pipelines from immediate corrosion when transferring critical or hazardous gases and fluids. It is considered corrosion-resistant if we compare it to other common materials such as cast iron or carbon steel. This property of stainless steel makes it the perfect choice for pipe flanges and fittings.

2. Sustainable

Stainless steel is sustainable. It is commercially recyclable, and recycling often can require less energy than producing new stainless steel. It is not just environmentally friendly, but also known for its durability and longevity.

Did you know around 50% of all stainless steel constructed in the country comes from recycled scrap metal? Therefore, these flange fittings can help you reduce your overall carbon footprint for a project. Approximately 50% of all stainless steel produced nationally comes from recycled scrap. Therefore, these flange fittings can assist you in lowering your overall carbon footprint for a project and putting previously sourced material back into circulation.

3. Versatility

This material is highly versatile. Manufacturers add other materials like nickel, molybdenum, or nitrogen to enhance stainless steel’s properties. You can ask the manufacturer to construct flanges with different standard dimensions and specifications of stainless steel material, depending on what is commercially available. It enables flanges to fit in a comprehensive range of industrial applications.

4. Aesthetic Appeal

Beyond their functional advantages, stainless steel flange fittings have an appealing aesthetic. The smooth, polished finish of stainless steel gives a clean and professional look. You can use these stainless steel flanges where appearance plays an essential role, and you would even see them in retail and residential applications in your own personal life.

5. Strength

The oil and gas industry requires installation and maintenance of robust material grades. Weld fittings and joints are not much stronger for liquid and gas flow equipment. Adding materials like titanium and molybdenum increases tensile strength and decreases the possibility of warping or deformation. The material alternatives like aluminum are not always suitable to work under extreme conditions like high temperatures or pressure.

6. Temperature and pressure tolerance

Stainless steel flanges have high tolerance power; depending on the metal grade, they can easily endure high pressure and temperatures. For instance, ASTM A182 flanges are suitable for temperatures of about 500 to 800 degrees Celsius. Flanges manufacturers follow the ASTM, API, or ANSI classification guidelines or the right pressure class for your application.

7. Value

Stainless steel fittings last for a long time. They support the flow of liquid and gases within the piping system. This material is reliable and easy to maintain without extra effort. The corrosion resistance property means you may not have to replace it, and you can find its usage for a prolonged period.

8. Easy to inspect

Pipe flanges, joining valves, and other equipment facilitate convenient cleaning and repair access. Properties like rust and corrosion-resistant stainless steel flanges enable effortless access for inspection, modification, or cleaning. It saves time and money overall.

Industrial Applications Where Stainless Steel Flanges is an Ideal Choice

Stainless steel flanges are useful in different applications, including residential, commercial, and industrial piping systems. Their strength, endurance, power, and corrosion resistance make them the right fit for transporting basic gases or liquids, hazardous chemical processing, maritime applications, and where corrosion resistance is a must.

Common Available Stainless Steel Flange Types:

Stainless steel flanges meet AWWA, DIN metric, and ANSI-class standards.

The typical stainless steel flange types include:

  • Slip-On or Ring
  • Socket Weld
  • Blind
  • Lap Joint
  • Weld-Neck
  • Threaded or Companion

In addition, other components like threaded couplings, braided pump connectors, nipples, and elbows are also available in this material.


You must consider the material choice while purchasing the flanges for your industrial application. From corrosion resistance, to withstanding extreme conditions, stainless steel flanges are the ideal choice for your application.

Q.1 Are stainless steel flange fittings easy to maintain?

Yes, they are relatively low-maintenance due to their corrosion resistance and robustness, requiring less frequent replacement and upkeep.

Q.2 Do stainless steel flange fittings require special installation procedures?

While they don’t need highly specialized installation, it’s crucial to follow proper procedures and use appropriate gaskets and bolts to ensure a leak-free connection.

Q.3 Are there any limitations to using stainless steel flange fittings?

Stainless steel is not suitable for extremely high-pressure applications or environments with high levels of chloride exposure, as it may still corrode under certain extreme conditions.

Q.4 Are there different types of stainless steel used for flange fittings?

Yes, stainless steel comes in various grades, with 304 and 316 being the most common for flange fittings.

Q.5 What are the seven advantages of using stainless steel flange fittings?

The seven main advantages include corrosion resistance, durability, high-temperature resistance, versatility, ease of maintenance, longevity, and cost-effectiveness.
