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 the connection methods for PVDF fittings?
1. Butt Fusion: Using a specialized butt fusion machine, the pipe ends are heated and melted at a specified temperature, then aligned and pressed together. After cooling, a seamless, leak-free connection is formed. This is the most common connection method for PVDF pipes and is suitable for high-pressure and clean systems.
2. Socket Fusion: The pipe is inserted into a preheated socket sleeve. After melting, it is quickly inserted and cooled, resulting in a strong connection that is easy to assemble quickly on-site.
3. Electrofusion: Using electrofusion fittings with built-in resistance wires, heat is generated by applying electricity to achieve fusion. This is suitable for situations where it is difficult to use a butt fusion machine on-site, especially common in long pipe sections or bends.
4. Flange Connection: A mechanical seal is achieved using flanges, bolts, and gaskets. This facilitates maintenance and replacement and is commonly used in large pipelines or systems requiring frequent maintenance. 5. Threaded/Compression Connections
Threaded connections allow for quick assembly via threaded engagement. Compression connections (such as ferrules) utilize the interlocking of a sleeve and pipe to form a seal, suitable for small-diameter or low-pressure systems.
What are the common specifications and dimensions of PVDF Fittings?
1. Pipe Diameter and Wall Thickness (Nominal Diameter DN)
Common outer diameter range: 20mm~110mm, wall thickness from 2.3mm to 12.3mm, meeting various industrial needs from small to medium diameters.
2. Standard Size Series
ISO10931 (SDR21S10): Applicable to Butt Fusion and Socket Fusion fittings, covering the entire range of DN20-110.
