Lined with PTFE magnetic flap
Thread Content
For concentrated hydrochloric acid, the PTFE-lined magnetic flap – why does the lining layer deform? Used for 5 years, with insulation but no heat tracing. The equipment is a atmospheric pressure tank; I want to know what caused the deformation of the lining
What is the temperature? The use of tetrafluoride should preferably not exceed 100, as it is prone to creep and deformation.
It’s best to take a photo, as well as to note any abnormal production conditions that may occur on a daily basis, such as changes in temperature or the presence of negative pressure And how thick is the PTFE lining? It is necessary to examine the reasons from various aspects, as well as to determine whether it is PTFE Could it be other materials such as polyethylene?
Today, it was decided that the lining material will be rubber, not PTFE
It’s normal for there to be deformation after five years; it shouldn’t be too severe. That’s what rubber linings are like.
