Why Choose Us
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.

Types of Asme B16.47 Ser,A Welding Neck Flanges
Long Weld Neck Flanges
Long WN flanges are also termed ‘standard weld neck flanges.’ It comes in various dimensions. For instance, as per ASME B16.5, a ½ long WN flange’s OD is 3.5, thickness is 0.44, barrel OD HB diameter is 1.5, bolting is 4 nos of holes, and RF length is 21/4. This falls in Class 150 Standard Connections WN Flange.
Reducing WN Flanges
A reducing WN flange is crucial in the industrial system in which smooth transitions between different pipe sizes are necessary. The associated tapered connection ensures smooth fluid and gas flow while minimizing turbulence.
NW Long Weld Neck Flanges
NW long weld neck flanges, also known as ISO-KF long neck flanges, are prominently used for experimental purposes. This WN flange type provides leak-tight sealing under vacuum conditions.
Applications of Asme B16.47 Ser,A Welding Neck Flanges
Oil and Gas Industries
Establishing long pipelines to transfer crude oil, natural gas, etc. from point A to point B.
In the processing plants’ systems of refineries, high pressure and high temperatures are active.WN flanges are used in the drilling systems of offshore plants.
Power Generation
WN flanges are used in steam and gas turbines, boilers, etc.
Due to their higher resistiveness and strength, WN flanges are used in nuclear power plants.
Chemical Industry
In the chemical industry’s piping system, WN flanges are used widely due to the associated corrosion resistance facilities.
Weld neck flanges are used in pharmaceutical manufacturing processes where the piping systems encounter sterile environments.
Marine Industry
WN flanges are used in sea vessels’ fuel distribution systems, hydraulic systems, and other critical systems.
In offshore LNG refineries, this flange type is usually used in LNG transportation systems.
