ASTM B474 UNS N08020 EFW Nickel Alloy Pipe
ASTM B474 serves as a well-defined standard specification for Electric-Fusion-Welded (EFW) Nickel-Chromium-Iron Alloy (UNS N08020) pipe. Commonly known as Alloy 20, this material is renowned for its exceptional ability to resist acidic environments, particularly when dealing with sulfuric acid. Alloy 20 is composed primarily of nickel, chromium, and iron, with additional elements such as copper and molybdenum added to enhance its corrosion resistance.
Key features of ASTM B474 UNS N08020 EFW Nickel Alloy Pipe include:
- **Corrosion Resistance**: It exhibits outstanding resistance to pitting and crevice corrosion, especially in environments with chlorides and sulfuric acid.
- **Weldability**: This alloy is highly weldable, making it ideal for electric-fusion welding processes.
- **Mechanical Properties**: It boasts high strength and excellent ductility, ensuring durability and flexibility.
- **Applications**: It finds use across various industries, including chemical processing, petrochemicals, food and beverage, and pharmaceuticals.
The chemical composition of Alloy 20 (UNS N08020) typically includes:
- Nickel (Ni): 32-38%
- Chromium (Cr): 19-21%
- Iron (Fe): Balance
- Molybdenum (Mo): 2-3%
- Copper (Cu): 3-4%
- Other elements: Trace amounts of carbon, manganese, silicon, phosphorus, sulfur, and columbium.
Alloy 20 is commonly used in applications such as storage tanks, mixing tanks, heat exchangers, process piping, pickling equipment, and chemical/pharmaceutical equipment.
The manufacturing process for ASTM B474 UNS N08020 EFW Nickel Alloy Pipe involves electric fusion welding, which ensures a high-quality weld with consistent properties along the entire length of the pipe. This method guarantees reliability and performance in demanding industrial settings.
To maintain strict quality control, pipes manufactured under ASTM B474 must pass several rigorous tests, including tensile testing, hardness testing, chemical composition analysis, hydrostatic testing, and non-destructive examination. These tests ensure that the pipes meet the necessary mechanical and corrosion resistance standards for their intended applications.

Accessories Related to Background System – Classification Overview
Â
Accessories related to the fuel station background management system are essential for enabling centralized control, real-time monitoring, data synchronization, and intelligent fuel operations. These components work as communication bridges between dispensers, payment terminals, tank gauges, and the control center. They can be classified based on function, communication type, integration level, and application scenario.
Â
1. By Function:
• Communication Controllers (Protocol Converters):
Translate different device protocols (e.g., RS-485 to TCP/IP) to ensure smooth data exchange between dispensers and the background system.
• Station Control Units (SCU):
Serve as the central interface for all on-site devices, including dispensers, tank monitoring systems, and payment terminals. Enable real-time data collection and dispatch control.
• Data Acquisition Terminals:
Collect operational data (fuel volume, transaction info, alarms) and upload it to the cloud or local server.
• Network Switches & Routers:
Provide stable and secure data transmission between site devices and background servers.
• Uninterruptible Power Supplies (UPS):
Ensure continuous operation of the background system in the event of a power failure.
Â
2. By Communication Type:
• Wired Modules:
Support RS-232, RS-485, and Ethernet-based systems, offering stable, interference-resistant communication.
• Wireless Modules:
Use 4G, Wi-Fi, or Zigbee for remote areas or where cabling is limited.
Â
3. By Integration Level:
• Standalone Modules:
Operate independently and communicate with a specific part of the system, such as fuel dispensers or card readers.
• Integrated System Gateways:
Combine multiple functions such as protocol conversion, data storage, and remote diagnostics into a single device.
Â
4. By Application Scenario:
• Retail Fuel Stations:
Enable real-time transaction tracking, shift management, and price control via POS integration.
• Fleet & Enterprise Stations:
Offer advanced access control, fueling limits, and consumption reports for internal management.
• Cloud-Based Systems:
Allow remote monitoring, multi-station management, and data analytics through IoT-enabled devices.
Â
All background system accessories are designed to ensure data integrity, system stability, and security, supporting the digital transformation and automation of modern fueling networks.
