الأسئلة الشائعة (FAQs)
Are slip-on flanges appropriate for underground sewage systems?
Slip-on flanges are not recommended for underground sewage systems. This is due to the required welding process in such a context. According to experts, it is better to use flange adapters. Looking for other more suitable flanges may also work.
Is any specific surface preparation needed before welding slip-on flanges?
For better results, you may thoroughly clean slip-on flange surfaces. This practice ensures that the flange is free of debris or contaminants before welding.
Are slip-on flanges suitable for steam systems?
You may use slip-on flanges for steam piping systems. However, remember that their suitability still depends on the specific pressure and temperature conditions. Before buying slip-on flanges for steam systems, first, verify the application requirements. Consulting relevant standards may also help.
Do slip-on flanges provide a leak-proof connection?
When properly installed and welded, slip-on flanges can provide a secure connection that minimizes the risk of leaks.
What standards govern the use of slip-on flanges?
The installation and testing of slip-on flanges are governed by standards such as ASME B16.5 and ASME B31.3, which specify requirements for dimensions, materials, and pressure ratings
