I would like to ask how to connect the inlet and outlet flanges of a fluorine pump?
Thread Content
Is it connected directly using plastic pipes and pump inlets/outlets, or is it connected through mating flanges and pipes like ordinary metal pumps? Since the pipe is made of plastic, welding is definitely not an option
There are now flanges lined with fluoropolymer, which can be used for connection; the flanges can then be welded to the pipes
I don’t understand, senior. In the case of flange connections, if it’s flanges designed for fluorine-containing fluids, then the owner will surely use pipes suitable for fluorine-containing fluids as well； Assuming the owner uses all-plastic pipes, are there specialized plastic mating flanges? How do I connect this? Bolt connection?
Then, may I ask, how are the inlet and outlet of fluorine pumps in general chemical plants connected?
Import and export expansion joints, and then flange connection?
Haven’t come across it before... so I’m here to ask for advice···
A flange connection will suffice; it’s best if the gasket is flexible. ABS engineering plastic can be joined by applying acetone. There are specialized fittings available on the market that can be purchased and used to make connections by oneself.
Both PP and PVC pipes can have flanges welded to them; fluorinated lining pipes have their flanges pre-fabricated
