Product Description

Long weld neck flange is a type of flange with a higher neck height, which improves the stiffness and load-bearing capacity of the flange. Compared with butt welding flanges, long neck flanges require a larger welding workload, higher electrode consumption, and cannot withstand high temperature, high pressure, repeated bending, and temperature fluctuations. However, its on-site installation is relatively convenient and can omit the process of welding and rubbing, making it popular in practice.

 

The main characteristics of long weld neck flanges are as follows:

1.Strong corrosion resistance

2.Sturdy structure

3.Easy to install

4.Size standard

5.Wide applicability
