How to calculate the height difference of 45 degree elbow of fire trench
Fire trench pipe fitting 45 elbow normal pipe mouth spacing
Is the outer diameter of the pipe (grooved pipe fitting), that is, from the lower plane to the center of the upper mouth. The outer diameter of the grooved pipe is between the CE center line ports in the figure
Do grooved fittings have 30 and 60 degree elbows
No! There are only 11.5, 22.5, 45, 90, and after these, they are sufficient for all kinds of situations. First, make a comprehensive arrangement and try to use only 45 and 90. If the site requirements cannot be met, set the pipeline arrangement according to 11.5 22.5. If not, use hydraulic pipe bender and press the pipeline into a small radian on site. Then with the above pipe fitting can be solved.
