EN PL Flange with 3 waterlines refers to the European flat welding flange with 3 waterlines. The following is its introduction:
Material characteristics
The materials of European flat welding flange (EN PL Flange) usually have a variety of options, including carbon steel, stainless steel, etc. Carbon steel material has a low cost, has a certain strength and corrosion resistance, and is suitable for general industrial environments; stainless steel material has better corrosion resistance and oxidation resistance, and is often used in occasions with higher corrosion resistance requirements.
Structural features
Flat welding connection: PL is flat welding (Plate). When this flange is connected to the pipeline, the pipeline is inserted into the inner hole of the flange and then welded on the outside of the flange. This connection method is relatively simple to operate and low in cost. It is suitable for pipeline systems with relatively low pressure and not extremely strict sealing requirements.
Waterline design: with 3 waterlines, the waterline generally refers to the annular groove machined on the sealing surface of the flange. Its function is that when the gasket is pressed between the flange sealing surfaces during installation, the waterline can increase the friction between the gasket and the flange to prevent the gasket from sliding. It also helps to better accommodate and distribute the sealing medium, improve the sealing effect, and enhance the sealing and stability of the pipeline system.
Sealing surface form: generally flat surface (FF) or raised surface (RF). The flat sealing surface is relatively flat and is suitable for situations where the pressure is not high and the medium is relatively mild; the raised surface sealing surface has a raised ring on the flat surface, which can better cooperate with the gasket and improve the sealing performance. It is suitable for some occasions with slightly higher pressure.
Application field
Water supply and drainage system: In urban water supply and drainage pipelines and water supply and drainage systems inside buildings, EN PL Flange with 3 waterlines can be used to connect various water pipes to ensure the sealing of the pipeline system and prevent water leakage. The 3 waterlines can effectively enhance the sealing effect and ensure the normal operation of the system.
HVAC system: This flange is also widely used in the chilled water, cooling water pipes and hot water supply pipes of HVAC. It can reliably connect pipes and adapt to water flow media of different temperatures and pressures. 3 waterlines help maintain a good sealing state during system operation, reduce the risk of leakage, and ensure the stable operation of the HVAC system.
General industrial pipelines: In some general industrial production, such as water system pipelines in food and beverage processing, papermaking, textile and other industries, EN PL Flange with 3 waterlines can be used to connect pipelines that transport water, steam and other media to meet the strength and sealing requirements of pipeline connections. 3 waterlines can improve the reliability of sealing and ensure the smooth progress of the production process.
