Overview

WRNM-331 high-temperature wear-resistant thermocouple

Product Details

Wear resistant thermocouples are generally used for temperature measurement in high-temperature and wear-resistant fields such as circulating fluidized bed boilers, boiling furnaces, coal mills, gas furnaces, cement rotary kilns, and metallurgy in power plants.

In addition, according to different industries, they can also be divided into wear-resistant cutting thermocouples and wear-resistant leak resistant thermocouples.

According to the different wear-resistant thermocouple protection tubes, they can be divided into the following applications:

type	code name	Performance Characteristics	Measurement range ℃	Outer diameter d (mm)	Suitable occasions
Stainless steel spray coating	NP	wear-resistant	0~800	Φ16，Φ22	Cement, Coal powder, Fluidized bed, Boiling furnace, cement rotary kiln
Stainless steel reinforcement	Q	life extension	0~800 Limit 0~1050	Φ22~Φ30
cemented carbide	NH10	耐磨、耐高温	0~1100	Φ16~Φ34
superalloy	NH12	Wear resistant, corrosion-resistant, high temperature resistant, good strength	0~1200	Φ20~Φ25
superalloy	NH13	Wear resistance, corrosion resistance, high temperature resistance, and good performance	0~1300	Φ22
High chromium cast iron	G	耐磨、耐腐、外径大	0~1050	Φ32~Φ38
