1000× 500× l1.165 formula for changing straight pipe into right-angle elbow

Elbows are often used to connect water pipes, mainly for turning and changing the direction of pipes. It accounts for a large proportion, and elbows with different pipes or wall thicknesses are different. So how to calculate the formula of elbow length? What problems should be paid attention to during construction? Let's take a look at the relevant knowledge right away.

First, how to calculate the length formula of elbow?

Take 90 and 45 elbows as examples, the length of 90 elbow (㎜)=R* 1.57 (bending half du diameter unit ㎜) 2); Material required for 90 elbow (M)= diameter *2.5* required quantity+radius; 45 elbow length (㎜) bending radius multiplied by * tan 22.5 (half of elbow degree). When buying an elbow, it will be more suitable according to the elbow material, outer diameter size and thickness.
