Product Description
Alloy Flanges
Alloy Flanges are available in a variety of steel alloys, which are listed below. The flanges come in a variety of sizes and shapes. Flanges are available in nominal diameter sizes ranging from 12 inches to 48 inches in diameter. NIKO STEEL AND ENGINEERING LLP is a major manufacturer of Steel flanges and a variety of other types of alloys and materials. The product specification provides flanges for use in high-pressure applications. The flanges are available in a variety of sizes and specifications. The chemical composition of the alloy steel flange material can influence its mechanical properties.
Superior Alloy ConstructionEach flange is crafted from robust alloy steel grades such as ASTM/ASME A182 F1, F5, F9, F11, F22, F91, incorporating elements for optimal strength, heat, and corrosion resistance. The forged and machined process ensures structural integrity for high-pressure and temperature applications.
Versatile Connection OptionsAlloy flanges are available in a wide range of connection types, including weld neck, slip on, blind, threaded, socket weld, and lap joint, catering to diverse piping system requirements. Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) end connections further broaden their suitability.
Comprehensive Testing & Quality AssuranceStringent quality measures like 100% radiography, ultrasonic testing (UT), Positive Material Identification (PMI), and hydrostatic tests can be performed on request. This ensures each flange adheres to international performance and safety standards before dispatch.
FAQs of Alloy Flanges:
Q: How are alloy flanges manufactured and tested for quality?
A: Alloy flanges are produced through forging and machining processes to achieve precise dimensions and superior mechanical properties. Each batch undergoes rigorous inspections including 100% radiography, ultrasonic testing, Positive Material Identification, and hydro testing, ensuring compliance with ASTM, DIN, ANSI, and other standards.
Q: What pressure ratings and temperature ranges do these flanges support?
A: These alloy flanges are available with pressure ratings from Class 150 up to Class 2500, supporting operational temperatures between -20C and 600C, depending on the alloy grade chosen. This versatility makes them suitable for a wide range of industrial applications.
Q: When should I choose a specific connection type, such as weld neck or slip on?
A: The choice depends on the application and required performance. Weld neck flanges offer high strength and are ideal for high-pressure and high-temperature service, while slip on flanges are easier to install and suitable for low to moderate pressure situations. Other types like blind, threaded, socket weld, and lap joint address unique system specifications.
Q: Where can these alloy flanges be used?
A: Alloy flanges are widely utilized in sectors like oil & gas, petrochemical, power plants, shipbuilding, and chemical processing, where reliable pipe connections are crucial for safe and efficient operations.
Q: What is the typical process for ordering and delivery of alloy flanges?
A: Customers can specify the required grade, size, connection type, and inspection standards when placing orders. Products are packaged in wooden boxes or pallets to prevent damage. Standard lead times range from 2 to 6 weeks, depending on order volume and specifications.
Q: How do these flanges benefit my piping systems?
A: Engineered for robust performance, alloy flanges offer excellent mechanical strength, resistance to corrosion and heat, and reliable sealing under challenging conditions. This contributes to the longevity and safety of complex piping networks.
