Product Introduction
Threaded flanges are common pipe connectors that achieve non-welded mechanical connections by directly screwing onto the pipeline system via internal or external threads, offering convenient and detachable installation.
Its core advantage lies in the convenience of installation and maintenance, making it particularly suitable for alloy steel pipeline systems where welding is prohibited, as well as special material connection scenarios with poor welding performance. It effectively avoids the additional stress caused by welding deformation.
We offer a full range of stainless steel, duplex, and flange in various sizes to meet different standards.

What is a threaded flange?
A threaded flange is a type of pipe flange with internal threads, which connects to an externally threaded pipe via threads, eliminating the need for welding.
What are the advantages of threaded flanges?
1. Efficient installation and maintenance: No welding is required. Connections are achieved through thread matching and bolt tightening, allowing for quick assembly and disassembly, and facilitating later maintenance.
2. Pipeline protection: Prevents damage to pipe materials caused by high welding temperatures, especially suitable for thin-walled pipes, special alloy pipes, or precision piping systems.
3. Strong sealing performance: The combination of precision thread structure and sealing gasket ensures reliable sealing and effectively prevents media leakage in medium and low pressure systems.
When should I use a threaded flange?
1. Medium and low pressure/temperature system: Ideal for pipelines conveying water, gas, oil or general chemicals, with operating pressure ≤ 10MPa and temperature ≤ 300℃.
2. Small diameter pipes: Typically used for pipes with a nominal diameter (DN) ≤ 50 (2 inches), where the threads are easy to machine and provide a reliable seal.
3. Non-weldable or sensitive pipes: Suitable for thin-walled pipes, special alloy pipes (e.g., titanium alloys, copper), or precision pipes that cannot withstand the high temperatures of welding.
When should I not use threaded flanges?
Threaded flanges are not suitable for high-pressure, high-temperature, or harsh media environments where tight sealing, structural integrity, and stability are crucial.
