Are there any standards available to guide the use of tees or socket weld connections for connecting main pipes to branch pipes? National standards would be preferred In what other situations is it necessary to use a reinforced nozzle, and in what situations can it be led out directly?
The standard specification in Chinese standards does not clearly specify whether to use tees or socket welds for connecting the main pipeline to the branch pipelines; this depends on the pressure of the medium involved, and stress calculations are also necessary. If the strength meets the requirements of the material, then it is not necessary to use reinforcement nozzles. For example, I was involved in the design of a delayed coking unit with an annual capacity of 1.2 million tons. In that project, the client requested that ready-made connectors not be used. Apart from the alloy pipes, the unit has been in operation for 5 years now without any problems.
Every time we do it, the materials department provides us with a \"branch pipe connection sheet\". It will specify the connection methods for different pipe diameters at each grade.
Reply to 3# zhuli2853: The materials department needs a copy of the “branch pipe connection table”. Where can this table be found?
This requires a branch table specific to the materials field. Generally, if a tee is available, it should be used; otherwise, a branch fitting platform must be employed
