Kromschroder Ceramic tube set 74918138

This ceramic tube set is a conical (tapered) burner pipe fitting for Kromschroder BIC and BICA burners of size 65. It has a length of 300 mm and an outlet diameter of 40 mm, with a distance from flange to front edge of 35 mm. The tube is made of silicon-infiltrated silicon carbide (SiSiC) and is rated for a maximum temperature of 1500 °C. The set includes seals and requires no additional burner block. It guides the flame and protects the surrounding metal parts from heat.

Ceramic tube sets are selected by inner and outer diameter, overall length, and wall thickness. The material grade determines maximum operating temperature and thermal shock resistance. To suit a specific burner, match the physical dimensions and fixing method to the burner head geometry. Because the tube profile and mating flange are tailored to the burner model, universal equivalents are rare.

Failures of this kind appear as cracks, chips, or glaze damage on the ceramic surface. After service, inspect the tube for these defects, and check that the sealing surfaces are clean and the tube sits without binding. Verify that any locating slots or markings match the original orientation to prevent flame misalignment or impingement on the burner head.
