Specification requirements for connecting branch pipes from the main pipe
Thread Content
For a branch pipe extending from the main pipe, what size of pipe should be used so that it can be connected directly to the main pipe by digging? In what situations is it necessary to use an eccentric tee? Which national standard or design specification mentions this requirement in this regard?
You should consider a level that is one tier lower than half of the main pipe size; for example, for a 100-pipe system, the maximum value that can be used is 40. Then, no holes are made if the main pipe is smaller than 50
It is best to refer to the opening requirements specified in the pipeline grade table provided by the design institute. When making openings in pipes, factors such as pressure and the type of reinforcement needed for those openings must be taken into account
The pipeline grade table specifies the methods of using pipe fittings, indicating whether they are finished products or open-ended; it also shows whether reinforcement is required for the open ends. For each project, we prepare a \"Pipeline Grade Table\" so that materials can be ordered uniformly, and it also facilitates the calculation of any necessary reinforcement
