Overview
A 130 flange is a type of pipe flange commonly used in industrial piping systems. It serves as a connecting point for pipes, valves, pumps, and other equipment, ensuring a secure and leak-proof joint. The '130' designation typically refers to a specific size or pressure rating, though exact specifications may vary by standard (e.g., ANSI, DIN, or JIS). Flanges like the 130 model are essential in industries such as oil and gas, chemical processing, and water treatment, where reliable piping connections are critical. They are manufactured from durable materials like carbon steel, stainless steel, or alloy steel to withstand high pressures and corrosive environments.
Structure and Working Principle
The 130 flange consists of a flat, circular disk with evenly spaced bolt holes around its perimeter. It connects to another flange or equipment using bolts and a gasket, which ensures a tight seal. The flange face may feature a raised surface (RF), flat face (FF), or other configurations depending on the application. When installed, the flange aligns with a matching component, and bolts are tightened to compress the gasket, creating a pressure-resistant seal. The design ensures easy assembly and disassembly for maintenance or system modifications, making it a versatile solution for piping networks.
Key Features
The 130 flange is known for its durability and adaptability. Its standardized dimensions allow for compatibility with a wide range of piping systems, reducing the need for custom fittings. The flange's material selection (e.g., stainless steel for corrosion resistance or carbon steel for strength) ensures performance in diverse environments. Another key feature is its pressure rating, which determines its suitability for high-pressure applications. Proper gasket selection (e.g., rubber, PTFE, or metal) further enhances its sealing capability, preventing leaks even under extreme conditions.
Application Areas
130 flanges are widely used in industries requiring robust piping systems. In oil and gas, they connect pipelines, pumps, and storage tanks. Chemical plants rely on them for handling corrosive fluids, while water treatment facilities use them for large-diameter piping. They are also common in power generation, HVAC systems, and shipbuilding. The flange's versatility makes it suitable for both high-temperature and cryogenic applications, provided the material and gasket are chosen appropriately.
Maintenance and Precautions
Regular inspection of 130 flanges is essential to prevent leaks or failures. Check for signs of corrosion, bolt loosening, or gasket degradation. Re-torquing bolts after initial installation may be necessary to maintain a proper seal. Avoid mismatching flange standards (e.g., pairing ANSI with DIN), as this can lead to alignment issues. Always use compatible gaskets and follow manufacturer guidelines for pressure and temperature limits to ensure long-term reliability.
B2B Procurement Guide
When sourcing 130 flanges, prioritize suppliers with certifications like ISO 9001 or API Q1 to ensure quality. Specify material grade (e.g., ASTM A105 for carbon steel) and pressure class (e.g., 150#, 300#) to match your application. Bulk purchases may offer cost savings, but verify lead times and MOQs. Consider suppliers who provide testing reports (e.g., PMI, hydrostatic tests) for critical applications. For reference, prices range from $10-$100 per unit, depending on size and material.
