Long Neck Joint Flange
C-Way Engineering Exports is one of the most professional long-neck flanges manufacturers, suppliers, and exporters in India, we are featured in high-quality products and competitive prices. We produce international standards ASME/ANSI/IS/DIN/BS/JIS Long Neck flanges. Standard sizes of carbon steel and stainless steel long neck weld flanges are readily available in the stock to deliver immediately.
As the name suggests long neck weld flanges have a neck length that is two to three times longer than the standard weld neck flange, it is also known as Extended Weld Neck Flange. The extended neck offers additional reinforcement and support to the pipe, reducing stress concentrations and enhancing the structural integrity of the joint. The longer neck also provides a greater separation between the flange face and the weld area, which helps to minimize heat-affected zones and distortion during welding.
These flanges typically have a raised face or ring-type joint facing to provide a sealing surface for gaskets or other sealing materials. They are available in various sizes, pressure ratings, and material grades to suit different application requirements. Long neck weld flanges are commonly used in high-pressure and high-temperature piping systems, particularly in critical applications where structural integrity and reliability are most important.
All Flanges with standard sizes and materials are readily available in stock for immediate delivery. "Looking for large diameter Flanges ? Contact us today for Customized Flanges.
Power Generation: Used in steam piping systems, boiler feedwater lines, and turbine connections in power plants.
Oil and Gas Industry: Found in upstream, midstream, and downstream operations, including pipelines, refineries, petrochemical plants, and offshore platforms.
Chemical Processing: Utilized in chemical plants, processing facilities, and reactors where corrosive fluids and high pressures are present.
Water Treatment: Used in water supply networks, desalination plants, and wastewater treatment facilities where high-pressure pipelines are required.
Enhanced Strength: The longer neck provides additional reinforcement to the pipe joint, improving its strength and resistance to pressure and temperature fluctuations.
Reduced Welding Stress: The extended length of the neck reduces the proximity of the weld to the flange face, minimizing heat-affected zones and weld distortion during welding.
Improved Flow Characteristics: The smooth transition between the pipe and the flange neck reduces flow turbulence and pressure drop, improving overall system efficiency.
Versatility: Long neck weld flanges can accommodate a wide range of pipe sizes and pressure ratings, making them suitable for various industrial applications.
We conduct a series of testing procedures to ensure the quality, reliability, and performance of our Flanges.
These tests are conducted at various stages of manufacturing, from raw material inspection to the final product testing.
