When your project calls for speciality steel alloy and aluminum pipe flanges and fittings, American Stainless delivers on your timeline so your project can finish on-time and under-budget.
Steel Alloys—The Industrial PVF Innovator
Specialty pipe fittings made from steel alloys offer unparalleled strength, corrosion resistance, and versatility in environments in which traditional industrial materials, such as stainless steel or carbon steel, fall short.
Keep your alloy pipe and tube systems together safely, reliably, and leak-free with American Stainless’s selections of special alloy steel pipe fittings and flanges.
Discover the Difference Specialty Pipe Fittings Make
Special alloy steel pipe fittings are built from alloyed metals that, when combined in specific proportions, provide far superior mechanical properties than either metal on its own, making specialty pipe fittings useful when a project calls for dialing in the exact strength, durability, and corrosion resistance of your PVF parts to ensure long-lasting, leak-free, structurally sound connections.

Exploring Types of Specialty Pipe Fittings
Steel alloys provide strength, durability, and resistance to harsh conditions to the types of pipe fittings used to control the flow of fluid throughout your system and connect your pipes without leaks or structural issues.
Stainless Steel
Stainless steel alloys such as 304, 316, 316, and Alloy 20 provide specialty pipe fittings and flanges with varying degrees of exceptional strength and corrosion resistance for a wide range of industries.
Duplex Steel
By combining austenitic and ferritic stainless steel, Duplex stainless steel, such as S31803 and S32205, are particularly useful for specialty pipe fittings in especially harsh environments.
Inconel®
These nickel-chromium superalloys enable specialty pipe fittings and flanges to maintain structural integrity under high stress, pressure, and heat and resist oxidation in extreme environments.
Hastelloy®
These nickel-molybdenum alloy steel pipe fittings boast outstanding resistance to severe chemical conditions in reducing environments and are highly resistant to pitting and stress-corrosion cracking.
Knowing the Right Alloys for Your Specialty Pipe Fittings
With so many varieties of special alloy pipe and tube fittings and flanges to choose from, all tuned to unique operational conditions, making the right choice of alloy is essential to ensuring that your flanges and fittings are optimized for your environment and operating conditions. When making your choice, assess how well the specialty pipe fittings and flanges available to you match your project’s requirements for:
Corrosion Resistance
Take care to evaluate the chemical composition of your fluids and the surrounding environment and select an annoy that offers the necessary resistance against acids, bases, salts, and other corrosive agents.
Temperature/Pressure
Determine the maximum and minimum temperature and pressure range your alloy pipe fittings and flanges will be subjected to and choose the alloy that maintains structural integrity and performance under these conditions.
Compatibility
Ensure that the specialty pipe fittings and flanges you choose are built from alloys compatible with the other materials used in your system to avoid galvanic corrosion and maintain integrity throughout your pipe system.

The Industrial Uses of Alloy Steel Pipe Fittings and Flanges
Specialty pipe fittings designed from stainless steel alloys, aluminum, and other materials are an exceptional choice for pipe systems in the extreme environmental conditions found in industries such as: oil and gas, petrochemical, water treatment, chemical processing, and power generation
Marine Applications
Many specialty fittings and flanges, including aluminum pipe flanges, find use in marine environments due to their resistance to salt water corrosion.
Chemical Processing
Special alloy steel pipe fittings resist the temperatures, pressures, and corrosive materials used in chemical and pharmaceutical manufacturing.
Power Generation
Systems such as steam turbines, boilers, and cooling towers require specialty pipe fittings capable of maintaining their structural integrity.
Oil and Gas
Special alloy pipe fittings and flanges offer exceptional strength and corrosion resistance in natural gas extraction and processing operations.
Petrochemical
Alloy steel pipe fittings can withstand the acidic and reactive chemicals used in the manufacturing of plastics, fertilizers, and other chemical products.
Water Treatment
Alloy pipe fittings and flanges can handle chlorinated water, brines, and other corrosive treatment chemicals, reducing maintenance needs.
Best Practices for Alloy Pipe Flanges and Fittings
When you select the right special alloys tuned to your project’s unique environmental and operational demands, getting the most out of them means following best practices to ensure optimal performance in keeping your pipe systems secure through the maximum service lifetime:
Installation
- Handle specialty pipe pipe fittings and flanges with care to avoid any damage that could impair their functionality and integrity.
- Prepare your surfaces prior to installation by ensuring they are clean and free from debris or contaminants before installation to achieve a good seal.
- Use gaskets that are compatible with the type of special alloy and the fluids in the system, since incompatible gaskets can degrade and cause leaks.
- Follow the manufacturer’s torque specifications closely when tightening bolts to avoid overstressing the material and ensure an even seal.
Operation
- Regularly check temperature, pressure, and chemical concentrations to ensure they are within the specified limits for the special alloy pipe fittings you are using. Exceeding these limits can cause failure.
- Prevent mechanical stress such as vibration, shock loads, or excessive thermal cycling, which can weaken your specialty pipe fittings and flanges over time.
- Continuously assess the chemical compatibility, especially if there is a change in the process or the cleaning agents used, which can impact the integrity of your alloy steel pipe fittings.
Maintenance and Troubleshooting
- Conduct regular inspections of your specialty pipe fittings to identify signs of wear, corrosion, or damage and prevent catastrophic failures.
- Keep your alloy pipe fittings and flanges clean from deposits, residues, and external contaminants that could induce corrosion.
- If inspection reveals pitting, cracking, or other forms of deterioration, replace the affected components promptly to maintain system integrity.
- Keep detailed records of all inspections, maintenance activities, and replacements to help in troubleshooting and in planning future maintenance schedules.
