Although loose flanges have strong adaptability, for working conditions with small caliber of DN50 and below, low pressure and fixed installation, more economical quick-connect joints and threaded flanges can be selected, specifically:
Small caliber of DN25-DN50 and working pressure ≤0.4MPa: Prioritize stainless steel quick-connect joints for faster installation, suitable for UV disinfectors in small pump rooms for secondary water supply and small water purification equipment;
Pipelines without deviation and no need for disassembly: Fixed slip-on welding flanges can be selected with lower cost and stronger sealing stability.
