Properties of Stainless Steel 347/ 347H Pipe Fittings:

Stainless Steel 347 is an alloy of chromium and nickel with the addition of niobium, which provides stabilization against intergranular corrosion. The high chromium and nickel content contribute to its corrosion resistance, making it suitable for applications in aggressive environments. Stainless Steel 347H is the high-carbon version of 347, offering improved high-temperature strength. The combined elements make these alloys resilient to oxidation and ideal for high-temperature service.

Applications of Stainless Steel 347/ 347H Pipe Fittings:

Stainless Steel 347/347H Pipe Fittings find applications in a variety of industries due to their unique properties. They are commonly used in the manufacturing of heat exchangers, boiler components, chemical processing equipment, and aircraft engine parts. The alloys' resistance to sensitization and corrosion makes them suitable for applications involving exposure to high temperatures and aggressive chemicals.

Types of Stainless Steel 347/ 347H Pipe Fittings:

Stainless Steel 347H Pipe Fittings are available in a variety of types to suit different applications within industries that demand corrosion resistance and high-temperature strength. Some key types of these fittings include:

Stainless Steel 347/347H Elbows: These fittings allow changes in the direction of the piping system and are available in different angles, such as 90 degrees and 45 degrees, to accommodate specific layout requirements.

Stainless Steel 347/347H Tees: Tees are used to create branches in the pipeline, facilitating the flow of fluids in multiple directions. They come in equal and unequal configurations to suit various system designs.

Stainless Steel 347/347H Reducers: Reducers are employed to connect pipes of different diameters, ensuring a smooth transition and maintaining the integrity of the piping system.

Stainless Steel 347/347H Couplings: Couplings are connectors that join two pipes together, providing a secure and leak-resistant connection. They are essential for the overall stability of the pipeline.

Key Features of Stainless Steel 347/347H Pipe Fittings:

Corrosion Resistance: The alloys exhibit excellent corrosion resistance in various corrosive environments, including acids and alkaline solutions.

High-Temperature Strength: Stainless Steel 347/347H Pipe Fittings retain their strength and mechanical properties at elevated temperatures, making them suitable for high-temperature applications.

Creep Resistance: The addition of niobium enhances creep resistance, making these alloys reliable in applications with prolonged exposure to high temperatures.

Weldability: Stainless Steel 347/347H Pipe Fittings offer good weldability, allowing for easy installation and fabrication of piping systems.

347H Stainless Steel Pipe Fittings Manufacturing Process

Hot forming or Extrusion Method

By forcing a heated billet through a molded die's opening, forged parts are produced by the process of hot extrusion. This article discusses lubricated versus non-lubricated hot extrusion.

Hydraulic Bulge method – Cold forming

Internal pressure and axial feeding are used in hydroforming tube to create the perfect sort of tube. The operation's results can be predicted using the finite-element method.

Deep Drawing Method for caps

Some of the most widely used techniques for creating caps involve cutting the plate into a circle and shaping it with a deep draw. The process of deep drawing sheet metal storage, also known as blanks, creates a circular or irregular shape that is longer than half of its diameter.

Flare Method for Stub ends

The flaring procedure is used to create lap joint flanges and stub ends. A flare or flange face with a cutout called the flow end. Welding is frequently used to generate stub ends after the forge block has been machined to the desired size.
