PTFE plate

Dear Hussein,

Slight deviation from the topic. Have you checked the thermal movement at the aforesaid point? See, my point is often at such high temperature (500°C) the pipe tends to move a lot in hot condition resulting in the pipe shoe being dislodged from the supporting steel or concrete. I would recommend you use a rigid hanger in place of a pipe shoe if you don't have any other constraint. If you really need a shoe with reduced frictional resistance use graphite plate in place of a PTFE pad.

With best regards,
Pankaj Mandal.

		 Dear Group Members

		 I will appreciate if you answer following question :
		 If temperature of pipe be ~500 C(930 F),can I use PTFE plate

		 under 4" shoe support ?
		 If no, what do you recommend?
		 Is there any general rule for PTFE plate or another material
selection to reduce friction factor ?
		 Best regards
		 Hosein
