A403 WP347H Seamless Elbow Butt Weld Fitting For Oil and Gas Pipeline

Overwiew

A403 347H stainless steel covers the standard for austenitic stainless steel forgings for pressure piping applications. Materials for fittings shall include stainless steel forgings, stainless steel bar, stainless steel plate, or seamless or welded stainless steel pipe fitting products. Stainless steel forgings or forming operations shall be accomplished by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more operations.

All ASTM A403 WP347H stainless steel pipe fittings shall be heat treated. Chemical and product analysis shall be performed and shall conform to the chemical composition requirements for carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum and titanium.

WP347H is a type of stainless steel alloy, specifically designed for high-temperature applications. Here are some advantages of using WP347H material:

1. High-Temperature Resistance: It maintains strength and stability at elevated temperatures, making it ideal for applications like power generation and chemical processing.
2. Corrosion Resistance: WP347H offers excellent resistance to corrosion, particularly against intergranular attack, due to the addition of columbium (niobium).
3. Weldability: This alloy has good weldability, allowing for easier fabrication and repair, which is crucial in complex piping systems.
4. Mechanical Properties: It possesses good mechanical properties, including tensile strength and ductility, which enhance its performance under stress.
5. Durability: WP347H is durable and can withstand harsh environments, extending the lifespan of components made from it.
6. Versatility: It can be used in a variety of applications across industries, such as oil and gas, chemical processing, and power generation.
