Riddhi Siddhi Metal Impex provides Hastelloy B3 Flanges designed for extreme chemical environments with excellent resistance to hydrochloric acid, sulfuric acid, and other aggressive agents. These flanges are composed of a nickel-molybdenum alloy that enhances their structural strength and reduces brittleness in various thermal conditions. Commonly used in chemical processing, pharmaceutical production, and pollution control equipment, they are available in different pressure classes and face types to suit demanding operational systems.
We are the top hastelloy b3 flanges manufacturers committed to international standards like ASTM B564 and ASME B16.5 for superior durability and fitment. Each flange undergoes precise machining, ultrasonic testing, and dimensional inspection to ensure flawless performance. Customizations in size, thickness, and pressure ratings are available based on specific project requirements. With streamlined inventory management and prompt logistics, we guarantee efficient fulfillment across industries that demand corrosion-resistant materials.
Easy-to-install flanges suitable for low-pressure and low-temperature systems.
Ideal for small diameter pipes requiring high leakage integrity.
What are Hastelloy B3 Flanges?
Hastelloy B-3 alloys are designed to withstand high stress and high temperatures. One of the main advantages of Hastelloy B-3 is its exceptional resistance to hydrochloric acid, regardless of temperature or concentration. Additionally, this alloy is highly resistant to other corrosive substances.
What is the difference between Hastelloy B2 and B3?
The main difference is their composition; Hastelloy B3 has slightly lower oxidation resistance than the more corrosion-resistant Hastelloy B2. Both can be formed into round bars for heat exchangers, pressure vessels, chemical reactor pumps, and valve components, among other uses.
What are the critical features of Hastelloy B3 flanges?
1. Hastelloy B3 flanges provide exceptional resistance to many corrosive chemicals, such as hydrochloric acid, sulfuric acid, phosphoric acid, and organic acids. They also exhibit resistance to pitting, crevice corrosion, and stress-corrosion cracking. 2. Hastelloy B3 maintains its mechanical properties and erosion resistance even at high temperatures, making it suitable for applications that require elevated temperatures. 3. Hastelloy B3 flanges are versatile and find applications in different industries, including chemical processing, petrochemical, pharmaceutical, and waste treatment. 4. Hastelloy B3 can be easily fabricated into flanges using standard manufacturing processes like forging, machining, and welding.
