Tube welding issues, please help
Thread Content
For the 700*400 tee, due to limited space, I want to weld the 400 mm diameter branch directly. Is that possible? The wall thickness is 8 mm in both cases, and it’s PN16; the fluid involved is… For the 350*100 tee, there is no standard version available, and again due to limited space, I want to weld the 100 mm diameter branch directly. Is that feasible? The wall thicknesses are 8 mm and 4 mm respectively, and it’s PN25; the fluid involved is…
In actual production, welding branch pipes at pipe openings is a common practice; as long as the welding quality is good, it does not affect performance, though it may look less attractive
The specifications allow for eye-type tees, but some of them require reinforcement. Given that the pressure in your case is quite high, it’s best to carry out reinforcement
For high-pressure or medium-pressure pipelines, welding cannot be carried out in this manner because there are regulations for both pressure vessels and pipelines.
Requiring reinforcement of the half-pipe fitting actually puts the burden on the user.
I work in design; how should I improve my skills? Is it something called a branch pipe stand?
You work in design, so you should know the various methods of reinforcing openings. . Calculate them one by one. Is it about using thicker pipes, adding reinforcement plates, or utilizing pipe supports? .
No..... I’ve never calculated it
No, it’s sufficient to cut a steel plate into an outer shield and place it over the weld seam before welding
In actual production, welding branch pipes at pipe openings is a common practice; as long as the welding quality is good, it does not affect performance
The focus is on why the space is limited in both places Is the piping layout that compact?
