Wear off the company's production site there thermocouple for high abrasion solid particles or fluid, when the protective tube can be cut off the damaged thermocouple. By wear head spray Ni + Wc35, the hardness of the steel increased. Production site for the presence of high abrasion solid particles or fluid, is indispensable temperature refinery catalytic cracking unit.
