The PTFE plates on the sliding bracket keep falling off – is there any solution?
Thread Content
The steam pipes are equipped with sliding supports, and polytetrafluoroethylene sheets are placed on these supports. Since the equipment starts and stops frequently, the pipes expand and contract regularly, which causes the polytetrafluoroethylene sheets to fall off easily. Is there any solution to this problem? The new types of sliding brackets are all made of mirror-polished stainless steel plates; it seems that PTFE plates can be fixed to the base plate with screws.
Those connected with bolts can be tried
There are various methods available. For tetrafluoro plates with a thickness of 5 MM or more, they can be fixed to the base plate using countersunk self-tapping screws; it is also possible to attach several small fixing blocks on both sides where movement occurs (these blocks must not protrude beyond the thickness of the plate). Wrapping a layer of solder around the area can also work. Some manufacturers use adhesive for fixation, and in this case, the quality of the adhesive must be good, as ordinary adhesives lose their effectiveness after some time has passed.
Yes, bolt holes can be drilled in the polytetrafluoroethylene plate. General diagram of UOP process package
Foreign designers use this approach for their designs. It involves adding a 2mm thick layer of red copper on top of the stainless steel disc. I think it makes sense. Relatively heat-resistant.
