How to calculate bend pipe dimensions
Thread Content
I hope an expert can reply: how to calculate the dimensions of bends at any angle for the outer pipeline of natural gas pipelines?
Calculate length based on the arc length of the center line
Could you explain how to calculate it specifically?
First, determine the bending radius – whether it is a long-radius elbow or a short-radius one. Then draw a circle based on that radius, and apply offsets corresponding to the pipe’s radius; by making an offset upwards and another downwards, the shape can be drawn. In a coordinate system centered on the circle, measure the desired angle, and that will give you the necessary value. What is drawn here represents a stamped elbow; to draw a welded elbow, it’s necessary to determine how many plates will be used for the elbow.
