Tesco Steel & Engineering is a leading manufacturer and exporter of Australia Standard AS2129 Table D Weld Neck Flanges, designed for high-performance and durable pipeline connections. Produced in our state-of-the-art Mumbai facility, these flanges are crafted using advanced machinery and strict quality control standards, ensuring precision, reliability, and long-lasting performance in critical industrial applications. Weld neck flanges are specifically designed to be butt-welded to pipelines, providing a seamless, leak-proof connection that is ideal for high-pressure and high-temperature systems.


These flanges are also commonly referred to as AS2129 Table D WNRF, AS2129 Table D WNFF, and AS2129 Table D WN Flanges. Installation involves welding the flange directly to the pipe, which ensures uniform stress distribution along the flange and the connected pipeline. This method prevents fatigue failures and provides superior structural integrity, making them suitable for applications where safety and reliability are paramount, including oil & gas, petrochemical, and power generation industries.


Tesco Steel & Engineering manufactures these flanges in a wide range of premium materials, including stainless steel, duplex steel, alloy steel, carbon steel, low temperature carbon steel (LTCS), copper nickel, nickel, monel, inconel, hastelloy, and titanium. These materials are carefully selected for their corrosion resistance, mechanical strength, and ability to withstand extreme operating conditions. By offering multiple material options, clients can choose the ideal flange for specific operational requirements, whether for offshore pipelines, chemical plants, or high-pressure process systems.


We export AS2129 Table D Weld Neck Flanges to multiple countries, including Australia, Germany, Italy, France, the United Kingdom, UAE, Saudi Arabia, and Qatar, serving diverse industries worldwide. These flanges are widely used in high-pressure pipelines, refineries, offshore platforms, chemical processing units, and water treatment systems. With superior manufacturing standards, advanced technology, and rigorous quality assurance, our weld neck flanges provide unmatched performance, durability, and reliability, ensuring that every pipeline installation meets international safety and efficiency standards.

Advantages of using Australian Standard AS 2129 Table D 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 D Weldneck Flange
