【Help】Plastic pipe expansion jointing process
Thread Content
I’m asking if anyone here is familiar with the expansion jointing process for plastic pipes? I’ve heard that many fluoroplastic flue gas heat exchangers use the expansion jointing process, but I’ve never seen it. Anyone who is familiar with this could please provide some information? I’d be extremely grateful!
Take a close look at the drawings to confirm that there is no metal tube for reinforcement inside the fluoroplastic pipe? Or refer to HG/T 4172 and 4174 standards
I just haven’t seen it, so I don’t know if it exists or not! I just heard from others that such a process exists, and I wondered how plastics can be expansion-welded. But I asked someone who knows about this in the past couple of days, and it contains a stainless steel tube inside
From what I know so far, metal sheet tubes and plastic tubes are feasible; a stainless steel core is used in between, with a minimum tube diameter of 8 mm. What about plastic tube sheets and plastic tubes? Based on your experience, is that also what you do? It is said that it can achieve an inner diameter of 5mm; could it also be a metal tube added?
The capabilities of various manufacturers vary; it is advisable to consult them, but expanding full-plastic pipes against tube sheets is not reliable
