How does the pipeline bend
Thread Content
I am designing a pipeline to be run along a wall; the angle between the two walls is 140 degrees (not 135 degrees), and the required distance between the pipeline and the walls is only 1 meter. Both walls are quite long. May I ask how I should design it at the corner of the walls?
Use two 90-degree bends installed vertically to make the turn
Any questions? There are many methods: for pipes under high pressure, bent pipes can be used, 180-degree elbows can be cut from straight pipes, or custom 140-degree elbows can be fabricated; for pipes under low pressure, shrimp-shaped elbows or straight pipes cut at an angle can be used as substitutes for elbows; for pipes with a small diameter, cold bending can be employed, and so on
Using a 90-degree elbow will allow you to achieve a 140-degree angle; using a 45-degree elbow may make it difficult to achieve that angle. It’s sufficient to mark the turns on the drawings; the construction team knows how to proceed
Thank you :lol :lol :lol :lol
All the accessories should be shown on the drawings; wherever a bend is indicated, there must be the corresponding component, and nothing should be left for the construction party to decide on on their own...
Great idea for the second floor; I didn’t expect that ^_^
Why must a standard elbow be used? It can be directly cut using a 45-degree elbow; it’s best to design one’s own elbow with a bending radius of at least 3 times the pipe diameter, as this gives a better appearance. I don’t quite agree with the suggestion from the second floor, as it is not aesthetically pleasing; if liquid needs to be drained from a lower position, the location of the valves will need to be reconsidered. . .
It is also necessary to ensure that no liquid accumulates during antifreeze purging.
For small companies that install it themselves, you just need to draw a schematic diagram； If it is a legitimate design firm, the drawings must be prepared properly. There are actually two methods: 1. The heights of the two pipes running along the wall should be different, with the height difference corresponding to the size of two 90-degree elbows ； 2. Remove a portion of a 90-degree elbow radially to create a 140-degree elbow, which is a non-standard design. Of course, it’s even more convenient to order a custom 140-degree elbow! :lol :handshake
A bent pipe or the end face can be cut using a 45-degree elbow
The approach on the second floor is innovative, but the pipes are not in the same plane, with two 90° elbows at the turns. It’s simply not beautiful enough. Additionally, resistance has been increased. There are indeed many solutions; either welded elbows or modified standard elbows can be used to meet the requirements.
