A Threaded Flange provides a strong, leak-resistant joint for non-welded pipe connections, making it ideal for systems that cannot tolerate heat from welding.
It is widely used in oil and gas, petrochemical, plumbing, and utility applications across Saudi Arabia, especially in Dammam, Riyadh, Jubail, and Jeddah.
Engineered for easy assembly and maintenance, the Threaded Flange in Saudi ensures secure performance in both low and high-pressure systems.
A Threaded Flange (also known as a screwed flange) has an internal thread that matches the male thread on the pipe.
It allows a secure, weld-free connection, making it suitable for environments where welding is not practical—such as flammable gas or vapor systems.
Unlike slip-on or weld neck flanges, the threaded type requires no welding, which saves time and reduces installation cost while maintaining mechanical integrity.
In Saudi Arabia’s diverse industries—where pipelines transport gases, fluids, and steam under varying pressure levels—the Threaded Flange offers a flexible, safe, and maintenance-friendly solution.
Weld-Free Connection: No welding required, reducing risk in explosive or flammable areas.
Easy Installation: Threads directly onto the pipe; perfect for quick setup.
Cost-Effective: Low installation and maintenance costs.
Reusability: Can be easily removed and reused during maintenance.
High Durability: Designed to withstand both pressure and vibration.
Material Versatility: Available in carbon steel, stainless steel, alloy steel, and brass.
Standard Compliance: Manufactured per ASME, ANSI, ISO, and API standards.
Corrosion Resistance: Ideal for chemical, marine, and water service applications.
The Threaded Flange is a versatile solution used in industries requiring frequent assembly and disassembly of pipe sections.
Oil & Gas Pipelines
Chemical and Petrochemical Plants
Water Treatment and Plumbing Systems
Steam and Air Distribution Networks
Marine and Offshore Installations
Industrial Cooling Systems
Firefighting and HVAC Systems
Its weld-free installation and mechanical strength make it one of the most convenient flanges for general and critical services alike.
