Nothing here is a shelf item. Insertion length, tube diameter, thread or flange, cable length, termination and accuracy class are specified for your installation.
Five protection-tube designs for the furnace chamber, each matched to a specific failure mechanism. Full engineering detail is on the dedicated page.
| Model | Protection tube | Range | Best for |
|---|---|---|---|
| JY-101 | Modified wear-resistant alloy | 0–1250 °C (K) | Fly-ash and slag erosion; impact and creep-bending resistance |
| JY-102 | Anti-chlorine alloy (6× corrosion resistance) | 0–1250 °C (K) | High-chlorine waste feed; chemically aggressive flue gas |
| JY-103 | High-temperature alloy | 0–1250 °C (K) 0–1400 °C (S) | Hottest zones; replaces brittle alumina tubes in Type S service |
| JY-104 | Overlay-welded (hardfaced) alloy | 0–1250 °C (K) | Combined corrosion + erosion duty |
| JY-105 | Composite ceramic | tube rated to 1600 °C | Extreme temperature; thermal cycling that shatters ordinary ceramics |
Developed for the specific wear and temperature mechanisms of each industry, based on continuous field testing of protection-tube alloys. All types use imported Type K thermocouple wire.
| Series | Application | Protection tube | Temperature | Typical service life |
|---|---|---|---|---|
| JY-201 | CFB boilers, coal-fired power plants | Ø16–Ø50 mm, length to order | 0–1300 °C | 6–24 months (by tube diameter) |
| JY-202 | Hot blast stoves, steel mills | Ø16–Ø38 mm; vibration-resistant construction | ≤ 1250 °C continuous | 3–12 months (by tube diameter) |
| JY-203 | Cement kiln inlet / outlet | Ø16–Ø38 mm; alloy selected for the working conditions | 0–1350 °C | 1 month and above |
| JY-204 | Carbon baking furnaces | Ø16 / 20 / 22 / 25 mm; special high-temperature corrosion-resistant alloy | 0–1300 °C continuous 1350 °C peak |
≥ 3 months; 6–12 months under well-controlled conditions |
Used by metrology institutes and calibration laboratories for calibrating environmental test chambers, muffle furnaces and heat-treatment furnaces — where stability and repeatability matter more than ruggedness.
