Please ask an experienced person to explain this description of the pipe fitting

90-degree elbow, LR, SMLS, BW, GB/T8163 20, SH/T 3408; diameter .75”, SCH160. 90-degree elbow with long radius, seamless, weldable. I know the material standards and manufacturing standards as well as the wall thickness standards, but I can’t understand the dimensions
.75\" is the inch diameter, corresponding to DN20 (3/4 inch)
0.75”=3/4”=DN20, outer diameter of about 27mm, wall thickness of SCH160 of about 5.56mm
0.75’‘ corresponds to DN20; Schmitt’s website provides a correlation between pipe diameter and wall thickness – 160 corresponds to 5.5 mm, with a weight of 2.92 kg/m
.75\" means 0.75 inches, which is 3/4 inch, equivalent to DN20
All the answers above are correct; P. I guess the original poster didn’t notice that decimal point.
To be honest, it’s about improving one’s technical skills; everything else isn’t important. It is important to learn from others, but it is even more crucial to be in control of one’s own actions.
It’s uncommon to use butt welding for something this small. But there are still many design institutes in China that use this type of small-diameter, thick-wall butt welding.
At first glance, it seems to be 75 inches, but upon closer inspection, there’s a dot...
Why not add a 0? Why not do it? Beat up the design
