Weld neck flanges are designed to integrate seamlessly with a piping system. While the production of these flanges can be more on the pricey side due to the design and the material used, they are the preferred choice when it comes to hostile environments. These flanges can also be made out of a variety of different metals such as copper, aluminium, stainless and galvanised steel which makes them versatile. 

Standard Vs Long

There are two different types of weld neck flanges – long and standard. The standard is used in conjunction with butt welds, while the long is used with vessel and nozzle equipment. To look at, the main difference between the two is that as the name suggests, the long neck weld flange has a longer neck than the standard weld flange

When using standard weld neck flanges, the join provided through with butt welding is a strong and durable connection. There is minimal chance of leakages and the piping systems have an unobstructed flow right through them. They are also used in piping systems that may encounter a large amount of bending.   

The Benefits Of Weld Neck Flanges

The design of weld neck flanges consists of a tapered hub that fits securely inside a pipe or fitting, creating a strong and durable join. This design also reduces friction and obstructions of flow through the systems.

Weld neck flanges are perfect for use under high-pressure environments up to around 5000 psi and in sub-zero as well as elevated temperatures. They are also suitable to be used with hazardous or volatile fluids. While they do require the skills of an experienced welder, there is an element of ease when it comes to the fitting and alignment due to the way they are designed.
