Round cover high temperature resistant

This product has been designed to be used for flues with operation temperatures higher than 200°C and up to 700°-800°. It is to be installed on a T pipe union, so as to allow inspection.
The round plug is made of two elements, one, outside, covers the pipe and the other, inside, goes into the pipe itself.
Between the two elements there is a metal seal AISI 302/316 with a heat-insulating jacket of ceramic fibre to insulate heat of the external element.
This seal, under pressure by means of an handwheel, expands and gets on contact with the internal surface of the pipe, thus creating that sealing effect against smokes passing trough the flue.
If necessary, the seal pressure can be modified by means of a threaded journal integrated in the handwheel.

The product is made of the following materials:

– Metal parts: sp. 10/10 AISI 304 BA – AISI 316L 2B or copper: Cu DHP UNI 5649/1
– Handwheel: AISI 303

In both steel and copper versions, on request the internal plate is available in AISI 316L 2B
