Nelson Metal Industries — Flanges Types Section (Weld Neck vs Slip On)
Types

Weld Neck vs. Slip On Flanges

Weld Neck Flange being welded to pipe

Weld Neck Flange

Identified by its long tapered hub that is butt-welded to the pipe, transferring stress smoothly from the flange to the pipe and reducing high-stress concentration at the base. Preferred for high-pressure, high-temperature, and sub-zero services where a strong, leak-free joint is critical.

Slip On Flange fitted on industrial pipe assembly

Slip On Flange

Slides directly over the pipe end and is fillet-welded both inside and outside for added strength. Easier to align and less expensive to install than weld neck flanges, making it a popular choice for low-pressure applications and general piping systems.
