PL Flange
SDFL
Flexible Structure：The flange ring is loosely connected to the pipeline, no need for integral welding with the pipeline, which can reduce stress deformation of the pipeline caused by welding and adapt to pipelines of different outer diameters;
2 .Easy Installation：Only need to sleeve the flat welding ring on the end of the pipeline and fasten it with flange bolts to complete sealing, which has low technical requirements for installers and shortens the construction time;
3 .Reliable Sealing：Matched with rubber, asbestos or metal gaskets, it can effectively block medium leakage and is suitable for non-corrosive normal-temperature media such as water, air and steam;
4. Economic Cost：Simple manufacturing process, high material utilization rate, cost 20%-30% lower than integral flanges, suitable for bulk procurement.
Building water supply and drainage pipelines: Cold and hot water transmission pipelines in residential communities and commercial buildings, which require frequent maintenance and non-corrosive media;
Compressed air pipelines: Air source transmission pipelines for pneumatic equipment in factory workshops, with working pressure ≤1.6MPa and normal temperature conditions;
Ordinary steam pipelines: Low-pressure steam transmission (temperature ≤180℃) in small heating systems and food processing workshops, no need for high temperature and high pressure resistance.
