Threaded Flange
Product Details
Threaded Flanges
We manufacture a wide range of high-strength, corrosion-resistant flanges in materials such as Stainless Steel, Carbon Steel, and various alloys to ensure leak-proof performance even in high-pressure environments.
Description
A Threaded Flange, also known as a screwed flange, connects to a male threaded pipe to create a tight and secure mechanical connection. Its primary advantage is that it can be installed without the need for welding, making it the ideal choice for flammable, explosive, or hazardous environments where welding is not feasible. Manufactured from high-quality carbon steel, stainless steel, and alloy steels, these flanges provide excellent durability and corrosion resistance. They are typically used in low-pressure, non-cyclic applications such as plumbing, fire protection systems, oil & gas, and chemical processing. Available in multiple pressure ratings like Class 150, 300, and 600, and supporting thread standards such as NPT and BSP, their easy installation, reusability, and weld-free design make them perfect for temporary systems or maintenance applications requiring quick connections.

Key Features
01 No Welding Required
Threaded flanges are perfect for applications where welding is not practical or allowed, such as in flammable environments or maintenance-heavy systems.
02 Leak-Resistant Threads
Precision tapered threads like NPT or BSP ensure a secure and leak-resistant connection, especially in low to medium-pressure applications.
03 Corrosion Resistance
Available in materials like stainless steel, nickel alloys, and carbon steel with coatings, offering long-term resistance in corrosive environments.
04 Standards Compliant
Produced according to ASME B16.5, ANSI, and EN 1092-1 standards, ensuring dimensional precision and global interchangeability.
05 Quick Installation & Removal
Threaded connections allow for fast and easy assembly or disassembly, ideal for systems requiring frequent maintenance or temporary setups.
06 Broad Industrial Use
Used across oil & gas, water systems, chemical processing, HVAC, and fire protection lines, especially where low-pressure and vibration-resistant joints are needed.
