One-piece collar pipes
Ceramic collar pipes are best used to carry metal-pin connection ends through the furnace wall for furnace ducts and to insulate current-carrying pins from the metal wall of the furnace. Berghütten offers a selection of these in standard dimensions at grade C 530. Grades C 610 and C 799 can be produced on request. In addition, custom dimensions can be tailored to customer requirements. The length range for the furnace wall thickness varies from a selection of up to 290 mm. We cut the collar pipe to length according to your specifications. For detailed technical specifications (e.g. for C 530 ceramic), please refer to our page on ceramic tubes.
