Calculation of the workload for digging eye tees
Thread Content
Does anyone who is an expert know how the quantity of work for digging eye connections is calculated, and are there any standards for carrying out this task? What other conditions allow the use of an eye digging tee?
Has anyone answered? I want to know too how it’s handled
This seems to be included in the supplementary quotas of the standard quotas; the quota number is in the format of letters followed by numbers. . . I have done it before. . . It’s on the computer at home; I can look for it when I get back
Only when the path ratio is 0.5 or higher can it be considered as part of the work volume. For DN200 pipes, digging more than 100 units is required to count as a tee; otherwise, it is counted as one weld.
The problems we face often also involve eye gouging.
When the diameter of the branch pipe formed by cutting a hole in a process pipeline tee is less than 1/2 of that of the main pipe, the volume of work is calculated based on the diameter of the branch pipe； For the tee branch pipe in process pipelines, the quantity is calculated when the main pipe diameter is 1/2, based on the diameter of the branch pipe ； When it is greater than 1/2, calculate based on the diameter of the main pipe
