产品概述

  In order to prevent the electrical connection and junction box cover and the box body thread connection by the environment harmful atmosphere erosion, uses the stainless steel flameproof junction box, the protection casing internal uses special card sets to clamp the armor temperature measurement element, forms the absolute seal structure, In order to prevent the outside after catheter is wear cause oil spill or leakage  Wear-resistant pipe has two structures and different materials for choice. A wear-resistant pipe is using a variety of different materials alloy pipe as needed, spray Ni60WC40 wear layer (code N) to the external .The other is the use of the overall drilling corrosion-resistant, heat-resistant alloy material as a wear-resistant head (code Z).


  This series of products for the production process there is a certain flow rate of solid particles or liquid, gas temperature measurement, is circulating fluidized bed (CFB), incinerator and oil refineries indispensable temperature measurement products.
