Tesco Steel & Engineering is a trusted manufacturer and exporter of Australia Standard AS2129 Table E Weld Neck Flanges, engineered with precision to meet the requirements of global industries. Manufactured in our state-of-the-art Mumbai facility, these flanges are designed for superior durability, accuracy, and strength. Weld neck flanges are installed by welding the flange’s long tapered hub to the pipe, creating a smooth transition that reduces turbulence, minimizes stress concentration, and ensures a leak-proof, high-integrity connection, even in high-pressure and high-temperature applications.


Also recognized as AS2129 Table E WNRF, AS2129 Table E WNFF, and AS2129 Table E WN Flanges, these products are widely preferred for their reliability and long service life. Their design makes them suitable for critical operations where safety and performance cannot be compromised, such as in power plants, refineries, offshore platforms, and petrochemical facilities. By providing a robust joint that maintains alignment and prevents leakage, these flanges are a first choice in industries requiring precision-engineered connections.


At Tesco Steel & Engineering, we manufacture these flanges in a wide range of materials including stainless steel, duplex steel, alloy steel, carbon steel, low temperature carbon steel (LTCS), copper nickel, nickel, monel, inconel, hastelloy, and titanium. Each material is carefully chosen for its ability to withstand corrosion, temperature fluctuations, and harsh operating environments. With this broad selection, we cater to industries as diverse as oil & gas, chemical processing, water treatment, marine engineering, and power generation, offering clients maximum flexibility and reliability.


We proudly export our AS2129 Table E Weld Neck Flanges to multiple countries such as Australia, Germany, Italy, France, the United Kingdom, Saudi Arabia, Qatar, and the UAE, serving both Western and Middle Eastern markets with superior products. Known for our uncompromising quality, advanced manufacturing technology, and rigorous testing standards, we ensure that every flange leaving our facility upholds the highest levels of performance and reliability. These flanges are widely used in pipeline systems, high-pressure equipment, offshore structures, and industrial process plants, making them a vital component for critical applications worldwide.

Advantages of using Australian Standard AS 2129 Table E Weldneck Flanges

Weldneck flanges offer several advantages over other types of flanges, such as slip-on flanges. Here are some of the benefits of using weldneck flanges:

Superior Strength
Weldneck flanges have a long tapered hub that provides additional strength to the connection between the pipe and the flange. The welding process creates a permanent and durable bond that can withstand high pressure and extreme temperatures.

Versatility in Accommodating Different Pipe Sizes
Weldneck flanges are available in various sizes, making them suitable for use with pipes of different diameters. The flanges can also be used with pipes of different materials, such as stainless steel, carbon steel, and alloy steel.

Secure and Leak-Free Connection
The welding process creates a strong and leak-free connection between the pipe and the flange. This ensures that the piping system is safe and efficient, reducing the risk of leaks and other safety hazards.

Easy to Install and Maintain
Weldneck flanges are relatively easy to install, and the welding process can be completed quickly. The flanges are also easy to maintain, requiring only periodic inspection and maintenance to ensure that they are in good working condition.



Applications of Australian Standard AS 2129 Table E Weldneck Flange
