Long Weld Neck Flanges

Heading section

We offer long weld neck flanges in alloy and non-alloy materials. These alloy long weld neck flanges are offered in various diameters and sizes. Long weld neck flanges are machined with the wall thickness of the flange having the same dimensions of the matching pipe.
The lighter is the pipe, the larger will be the bore and vice versa. These flanges are equally suitable for high-pressure, cold or hot temperature applications.
