DN20 elbow
Thread Content
Are there 90-degree short-radius elbows in DN20? After checking relevant information, for this specification, 90-degree elbows are only available with a long radius; there are no ones with a short radius. The drawings from Germany show that 3/4 size elbows are used with a center distance of 28.5, but this standard cannot be found
3/4", why such a small radius? Can’t let go? Elbows can be used in all cases.
His request is very strange; even using a bent pipe seems not to work. The minimum for elbow pipes should be 3D; it’s better to use 1.5D elbows instead. I’m not sure about that German standard; I’ve never come into contact with it.
Then simply use threads and opt for a tubing elbow.
What elbow? Is it a bent pipe fitting?
It is an elbow welded at the pump’s drain point; the elbow is too large, leaving insufficient space below it. Because increasing the pump height is not worth it. Therefore, it must be solved using a small-sized elbow. The key point is that we have the original German designs available, so during the design process, the management required that the designs be made according to German dimensions. It’s so frustrating
Then can we use tubing connectors? For example, Parker, Swagelok, Hylok. . .
