The minimum internal diameter of the elbow shall be such that the flow area is equal to that of the pipe and shall not be less than 90% of the area of the pipe. The length of the straight section of the elbow shall be greater than the sum of the axial length of the end face groove and the size of the transition area. The angle deviation of elbow shall not be more than 0.5. , The roundness of the bent part should be less than 506. DN400 above the low pressure elbow roundness can be less than 7%.
