Zavareni plastični cjevovod gotovo nikada ne kvari na zavarivanju; zakaže tamo gdje je nešto bilo uvučeno u njega. Taj se uzorak ponavlja u kemijskim postrojenjima, klizačima za obradu vode i mokrim stolovima za poluvodiče: β-PPH ili PVDF linija radi tiho godinama, a zatim spoj na priključku pumpe, manometru ...
Prikaži višeInženjer linije za oblaganje uredno je opisao problem: glavni razvodni kolektor ide duž zida, a četiri kapi spreja trebaju se puniti s istog mjesta, dvije s lijeve i dvije s desne strane, na identičnoj visini. Taj čvor možete izgraditi od dva T-kraka i spojnice, udvostručavajući zavare i mjesta curenja, ili to mo...
Prikaži višeSpojka s ženskim navojem crijeva od 3/4 inča može izgledati kao običan cijevni navoj, ali nije. Kad nam je inženjer za održavanje u stanici za doziranje kemikalija rekao da njegova PPH cijev neprestano plače na spoju crijeva, uzrok je brzo identificiran: netko je navukao FHT zakretni dio na NPT spojnicu. Teren ni...

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)
