EN 10220, EN 1127 Pipe Size Charts

The EN 10220 and EN 1127 specifications cover the dimensions and tolerances of European pipes, carbon/alloy steel, and stainless steel respectively. While EN 10220 and 1127 are used in Europe, ASME B36.10 and ASME B36.19 cover the dimensions and tolerances of American standard pipes.

EN 10220 PIPE SPECIFICATION

The BS EN 10220 specification covers the dimensions and the tolerances of carbon and low-alloy pipes manufactured in Europe.
OD = Pipe outside diameter in mm
WT = Pipe wall thickness in mm
