Piping Projects Middle East is a leading Long Weld Neck Flange Manufacturer. An long welded neck flange is a self-reinforcing connection used in ASME pressure vessel applications. It replaces a Long Weld Neck Flange and pipe for a more accessible bolt up to the vessel, reducing stress on the neck. The reinforcement of the Carbon Steel Long Weld Neck Flange plays a crucial role in preventing hazards in high-pressure systems and various industrial and domestic applications. We are the top Long Weld Neck Flange Suppliers in Middle East.
The long weld neck flange is the best and most recommended type. It has a weld bevel and a neck extension at the end. It is designed to supply a natural connection form. The specific needs of each application determine the lengths of the flanges, so there is no universal standard length for these industrial long-neck flanges. We are also a leading Blind Flange Manufacturer in Middle East.
As a leading Long Weld Neck Flange manufacturer in the Middle East, we are dedicated to providing reliable and top-notch long-welded neck flanges. Here are the specifications for the Long Weld Neck Flange.

What is a Long Weld Neck Flange?
Long weld neck flanges have a longer neck than standard weld neck flanges, acting as a boring extension. They are recognizable by their long tapered hub that decreases in size from the pipe to the fitting. These flanges are commonly used in high-pressure and high-temperature industrial settings. We stand for on-time deliveries as we are the top Long Weld Neck Flange Supplier in UAE.
Long Weld Neck Flanges are frequently used in the oil, gas, and petrochemical sectors to substitute pipes. Unlike regular weld neck flanges, long weld neck flanges have a square cut on the end instead of a weld prep at the neck and do not feature a schedule bore. They are offered in different lengths, the most common being 9 inches, 12 inches, and 16 inches. We are also a top Long Weld Neck Flange Manufacturer in Middle East.
