Notes:1. E is for international pipes. If used on metric pipe, E will be changed, but L is constant.2. There are three grades for weldolets - STD, XS, XXS. In order to choose which is
needed, please specify DN, OD and thickness of the pipe.4. Also please specify the dimensions of the main pipe and branch pipe and the pipes
grade and their material.
