Can a DN25 pipe be directly drilled and welded with a DN25 drain pipe?
Thread Content
For DN25 pipes with a pressure rating of PN11.0, when installing drain vents, tees were not used; instead, holes were made and welded directly. Are there any specific regulations regarding this approach? Can the strength requirements be met? Could there be any safety hazards? ?
If it is a common medium, it can be welded. However, when dealing with substances that are prone to decomposition, such as hydrogen peroxide, welding is not advisable; instead, use a pre-made tee by cutting a section from the pipeline and then welding the tee onto it. To meet the requirements. Currently, the standard practice in factories is to weld Dowlene directly, but be sure to clean and polish the opening before welding to prevent slag from blocking the pipe.
PN11.0 pressure is not low; it’s better to avoid it, right? It’s not a big deal to use just a small tee instead
