1. Rapid Assembly: Socket Fusion Fittings utilize a hot-melt socket welding process. Welding is completed simply by inserting the pipe into the sleeve and heating for tens of seconds. The overall operation time is significantly shorter than the minutes or even hours required for traditional arc or gas welding. 2. Low O...
View More1. High Temperature Resistance Taking fluoroplastics (PTFE, FEP, PVDF, ETFE, PFA) as an example, their maximum operating temperature can reach 260℃, with a low temperature limit above -18℃. Conventional plastic piping (such as PPR and PVC) can be used stably for a long time below 90℃, but softening or even failure will...
View More1. Determine the Media Characteristics First, determine whether the medium being transported by the plastic pipe is water, oil, chemical solvents, or gas. Select materials based on its corrosiveness, viscosity, and temperature range. PPR is suitable for hot water, PVC for acid and alkali media, and PE-RT for low-temper...
View MoreWhat are Foot Valves PPN?
1. Basic Principle A foot valve is a check valve installed at the pump inlet or the end of a pipeline. It opens when the liquid flows in the forward direction using a spring or gravity, and automatically closes when the liquid stops or flows backward, preventing backflow.
2. Advantages of PPN Material
PPN (Polypropylene N) is a highly transparent, low-absorption, and chemically resistant engineering plastic. It possesses excellent pressure resistance, impact resistance, and high-temperature resistance, making it suitable for applications in water treatment, chemical, and food industries where high material purity and durability are required.
3. Characteristics of Foot Valves PPN
Reliable Backflow Prevention: The valve body uses a spring-loaded self-closing structure, ensuring rapid closure regardless of changes in external pressure.
Strong Material Compatibility: PPN is virtually unaffected by acids, alkalis, salt water, and oils, extending its service life.
Lightweight Design: Compared to metal valve bodies, PPN material is lighter, facilitating handling and installation.
