Can there be multiple welds in the radial direction of a pressure pipeline? Ths
Is the poster referring to the weld of a grooved pipe? If this design specifies the use of such a material at low pressures, then the presence of such welds is permissible; the definition of pressure pipelines only specifies requirements regarding the medium and pipe diameter, without mentioning whether the pipes are welded or seamless.
Yes, as long as the inspection is successful, multiple welds are allowed~~
I am referring to the situation where several branch pipes are connected simultaneously along a main radial direction.
Yes, as long as the welding process is proper, multiple branch pipes are allowed. However, it is necessary to pay attention to the inherent physical and chemical properties of the pressure pipeline material in order to prevent the occurrence of stress. Special materials require proper heat treatment. For branch pipe welds made of ordinary carbon steel and common materials, it is sufficient that they meet the welding process requirements, which are generally specified by the design team.
There are no regulations, so it’s certainly allowed. Reinforcement needs to be considered. Additionally, the outer tube of the jacket must have two radial welds in certain areas.
Strength issues are the main concern; for main pipes with larger diameters, there are no major problems. Such pipes are generally used for connecting instruments or for draining contents, and it is not recommended to use this method to connect process pipelines.
