Dip tubes
The dip tube stops raw meal short-cutting the cyclone. When segments distort or drop, separation falls and more meal circulates to the upper stages. Fuel and fan power rise with it.
- Works in
- Segmented dip tubes, also called vortex finders or thimbles, in preheater cyclones.

How it fails and what we do about it
- 01Distortion and creepSection and hanger design that carries the segment at temperature.
- 02Scaling and oxidationHK type in the lowest, hottest cyclones.
- 03Segments dropping outHanger lugs and interlocks cast to drawing and checked on a fit-up set.
02
Choosing the grade
Typical values from the governing standards. A metallurgist confirms the grade for your duty with every quotation.
03
What we control
- Chemistry firstChromium and nickel verified on the spectrometer for every heat and recorded against the casting.
- Designed to stay straightRibs and sections arranged so the part can expand without warping.
- Fit-up checkedSegments, hangers and interlocks checked so sets assemble on site without rework.
- Traceable to the heatEvery casting carries its heat number, with the chemistry report to match.
04
