Applications & Selection Guide

Carbon steel threaded (screwed) flanges to EN 1092-1 / ASME B16.5 with an internal pipe thread — flanged connections without any welding.

Threaded flanges suit galvanized piping (where welding would destroy the coating), low-pressure utility lines, compressed-air systems, and hazardous areas where hot work is restricted. Thread engagement carries the load, so they are limited to smaller diameters and non-cyclic, moderate-pressure service. Sizes and PN classes are listed above.

Quoted and sold per piece. Include thread size, PN, quantity, and delivery country in your quote request and we will confirm availability and pricing.

This page lists PN16 threaded flanges from DN15 to DN150. The thread follows the nominal size: DN15 takes a ½" pipe thread, DN25 1", DN50 2" and DN100 4". The bolt pattern is that of any PN16 flange of the same DN, so a DN50 threaded flange has a 165 mm outside diameter, a 125 mm bolt circle and 4 × M16 bolts and bolts straight to a DN50 PN16 weld-neck or blind flange.
