Furnace Tubes
We offer a range of large furnace tubes. All our furnace tubes are a special creep-resistant grade suitable for use over 1700°C. The standard length is 1000 mm. All of these tubes are gas tight. We can supply furnace tubes with the ends accurately ground to suit O-ring seals for a small additional charge.
Our standard sizes (outside diameter x inside diameter) are:
- 89x80
- 84x75
- 80x70
- 74x63
- 70x60
- 60x50
- 60x53
- 50x40
- 46x40
Please also enquire for custom sizes.
Sample Application
Controlled Bluntness
The tips of the multiple blades of a highly specialised cutting shear had to be just fine enough to follow a soft, irregular surface, but blunt enough to be sure that they would not cut or puncture it. We came up with a precision extruded section having two concave grooves along it with controlled root radii of 0.18 and 0.16 mm.
