THREADED FLANGE
Threaded flange is a pipe flange connected by threads. The flange has internal threads that match the external threads of the pipe. This flange is connected to the pipe by screwing, without welding, and is a detachable connection method.
STRUCTURAL ADVANTAGES
Easy Installation, No Welding Required:
The Threaded Flange Is Directly Connected To The Pipe Through Threads, Eliminating The Welding Process And Greatly Reducing Installation Time And Labor Costs.
Detachable Connection For Easy Maintenance:
The Removal And Replacement Of Pipes Or Equipment Is Very Convenient, Suitable For Systems That Require Frequent Maintenance. The Flange Itself Can Be Reused To Reduce Maintenance Costs.
Less Impact of High Temperatures:
No Welding Is Required, And The Threaded Flange Avoids The Heat-Affected Zone Problem Caused By Welding.

REUSABLE CONNECTION
Threaded flanges can be easily unscrewed and reused, providing flexibility for pipe modifications, repairs, or temporary connections.
RELIABLE SEALING PERFORMANCE
Combined with sealing materials such as PTFE tape, gaskets, or sealants, threaded flanges ensure leak-free and secure connections even in demanding conditions.
IDEAL FOR SMALL-DIAMETER AND LOW-PRESSURE SYSTEMS
Designed for small-diameter pipes (DN15 to DN100) and moderate pressure applications, they offer an economical and efficient solution.
SAFE FOR HAZARDOUS ENVIRONMENTS
Perfect for environments where welding is prohibited or impractical, such as flammable or high-risk areas, ensuring safer operation.
WIDE COMPATIBILITY WITH GLOBAL STANDARDS
Available in NPT, BSP, and other international threading standards, threaded flanges are suitable for a variety of global applications across industries.
