Threaded flanges are essential components in industrial piping systems, offering a reliable and efficient alternative to welding. Designed with internal threads, these flanges allow for secure connections without the need for high-temperature welding, making them ideal for sensitive environments or applications where frequent disassembly is required. This article provides an in-depth exploration of the **Threaded Flange**, including its features, technical specifications, applications, and the company behind its production.

What is a Threaded Flange?

A threaded flange is a type of pipe flange that features internal threads, enabling it to be screwed directly onto a pipe with matching external threads. This design eliminates the need for welding, making it a preferred choice in situations where welding is impractical or unsafe. Threaded flanges are commonly used in small-diameter pipes and high-pressure systems, offering a secure and leak-proof connection without compromising the integrity of the pipe.

Key Features of Threaded Flanges

Threaded flanges are engineered to meet the demands of diverse industrial applications. Below are some of their standout features:

• Welding-Free Installation: The threaded design allows for quick and easy installation without the need for welding equipment, reducing downtime and labor costs.
• Material Versatility: Available in carbon steel, stainless steel, and alloy steel, these flanges ensure durability and resistance to corrosion.
• High-Pressure Compatibility: Threaded flanges are suitable for high-pressure systems, providing a secure connection even under demanding conditions.
• Easy Maintenance: The ability to disassemble and reassemble without damaging the pipe makes these flanges ideal for frequent disassembly and reconfiguration of piping systems.
