ASTM A403 WP347H-S 90 DEG. LR Elbow SS ButtWeld Fittings for Chemical Processing Plants
Description
ASTM A403 WP347 is a non-heat treatable, austenitic, electric furnace processed grade of stainless steel very similar in composition to Type 321. The major difference between Type 321 and Type 347 is that rather than having an addition of titanium, Type 347 has columbium added to it. Tantalum occurs in nature in conjunction with columbium and therefore it may be said that both are additives to this alloy. Type 347 can withstand more severely elevated temperatures than Type 321, as the resulting columbium carbide is more stable and insoluble than the titanium carbide. The only drawback in the use of Type 347 as opposed to Type 321 is that it is not recommended for use in radioactive services as radioactive tantalum has a much longer half-life than columbium. It is non-magnetic in the annealed state.
Advantages
A403 WP347H-S is a specific grade of stainless steel that is commonly used in piping applications, and a 90-degree long radius (LR) elbow is a type of pipe fitting. Here are some advantages of using A403 WP347H-S 90 DEG. LR Elbow:
Corrosion Resistance: A403 WP347H-S is a high-temperature and corrosion-resistant stainless steel grade. It contains chromium and nickel, which provide excellent resistance to corrosion in various environments. This makes it suitable for applications where corrosion is a concern.
High-Temperature Resistance: A403 WP347H-S is designed to withstand high temperatures, making it suitable for applications involving elevated temperatures such as in the petrochemical, chemical, and power generation industries. The 90-degree LR elbow made from this material can handle high-temperature fluids and gases.
Durable and Long-lasting: Stainless steel, including A403 WP347H-S, is known for its durability and longevity. It can withstand harsh conditions and is less prone to degradation over time compared to other materials. This ensures a longer service life for the 90-degree LR elbow.
Ease of Fabrication: Stainless steel, in general, is known for its ease of fabrication. It can be easily welded, formed, and machined into various shapes, including the 90-degree LR elbow. This ease of fabrication can simplify the manufacturing and installation processes.
Low Maintenance: Stainless steel requires minimal maintenance. It is resistant to rust, stains, and corrosion, reducing the need for frequent inspections and maintenance. This can be advantageous in applications where access for maintenance is challenging.
Hygienic Properties: Stainless steel is inherently hygienic and non-reactive, making it suitable for applications in industries such as food and pharmaceuticals. The smooth surface of the material discourages the growth of bacteria and other contaminants.
Versatility: The 90-degree LR elbow made from A403 WP347H-S can be used in various piping systems and applications, providing versatility in design and installation.
