Know all about Long Weld Neck Flanges

Long weld neck flanges are the type of flange that is more like weld neck flange but with lengthened boring extension functions. The long welded neck joins the pipe to the flange. The major aim of this sort of flange is to allow for simple installation and removal. This makes it suitable for a wide range of applications, including those involving pipe systems. These flanges can be used at pressures with high temperatures in industrial or construction sectors. Oil and gas also petrochemical industries generally use these flanges.

These flanges are used to connect pressure-rated pipes. Long weld neck flanges are different from other flanges as it has long neck diameter which helps them to bear more pressure.

Here are some of the characteristics of a long weld neck flange:

• It is composed of steel and has a polished look, making it simple to maintain.
• It is made to stand against pressure and is corrosion resistant.
• It is also easily set up and needs no help with it.

Applications of long weld neck flanges:

The long weld neck flange’s main application is to connect the pipes. So these flanges are available in a variety of materials like Inconel, stainless steel, and carbon steel.

In the oil and gas industry, particularly in fluid transfer, long flanged weld necks play a key role. Several sectors like steel mills and refineries use long weld neck flanges. As well as joining pipes and vessels, flanges are commonly used to support pipes, as structural elements, and for other purposes.

Applications that need high-pressure temperature use long weld neck flanges as it provides amazing features. Air conditioners and water sprinklers used these flanges and in many other applications as well.

Length and barrel varieties of long weld neck flange:

So the sizes of these flanges are available in popular lengths of 9″, 12″, and 16″, which makes it greater to customer needs. If the nominal size and pressure class of the flange are large, the overall length will be large as well.

Barrel types are thicker and more resilient than length types because their internal diameter is greater than their exterior diameter. Due to their thinness, length variations have an exterior diameter that is as large as or larger than barrel types. As a result, they are also less expensive than barrel variants due to the fewer resources and manpower required to produce them.
