Anticorrosive Thermal Resistance

WZP-230N Anticorrosive Thermal Resistance produced by SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD.，In some special occasions, such as chemical plants, smelters, thermal power plants and so on must use special materials and structure of the thermal resistance and thermocouple.

Introduction

Anticorrosion resistance of both anti-corrosion copper resistance and anti-corrosion platinum resistance two kinds of anti-corrosion platinum resistance is the most commonly used anti-corrosion thermal resistance. Is the most commonly used in a low temperature zone temperature detector. Its main feature is the measurement of high precision, stable performance. Which platinum thermal resistance measurement accuracy is the highest, it is not only widely used in industrial temperature measurement, and was made a standard benchmark.

Features

1, anti-corrosion thermal resistance  produced by SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD. using multi-layer corrosion (corrosion-resistant thermal resistance coating protection tube is usually thick-walled 316L or 304L steel pipe outside the overall sintered PTFE layer and wear-resistant coating) structure, corrosion effect and service life by many domestic enterprises Long-term use of factual verification.

2, anti-corrosion resistance of the polytetrafluoroethylene anti-corrosion layer Our company uses the most advanced sintering process of the original sintering, to solve the other manufacturing process can not avoid the seams easy to leak problems. The application of this technology to the company's anti-corrosion resistance and other anti-corrosion products, the average service life (in no larger wear environment) more than one year.

3, the use of the scene often exist at the same time there is a high flow rate of the media particles on the thermal resistance of the serious erosion of the coating, the company anti-corrosion resistance in addition to a layer of wear-resistant layer, Life of 8-10 times, different from other domestic anti-corrosion resistance of the same type.

4, all kinds of anti-corrosion resistance of the domestic first-class components, the entire product performance is stable, reliable, long life than the same type of domestic resistance to thermal resistance several times, long-term work in the temperature ≤ 220 ℃ temperature range.

Technical indicators

1, anti-corrosion resistance of the polytetrafluoroethylene coating thickness: 1.0mm (also available by the user).

2, the thermal response of thermal resistance of thermal resistance time: by the anti-corrosion treatment, thermal response time changes of about 20% (≤ 8S);

3, corrosion resistance of the thermal resistance of the coating quality inspection: the use of EDM microporous detection, voltage 12kV, frequency 1.6 × 106Hz without breakdown.

4, anti-corrosion thermal resistance of the working pressure: anti-corrosion thermal resistance fixed way for the installation of the flange when the maximum pressure 4.0MPa; anti-corrosion thermal resistance fixed F4 connection thread when the maximum pressure of 0.6MPa.

5, anti-corrosion resistance of the other technical indicators and general industrial thermal resistance of the same.

6, electrical exports: M20x1.5, NPTI1 / 2

7, protection class: IP65

8, explosion-proof grade: d‖BT4.d‖CT5

Precautions

Anticorrosive thermal resistance  produced by SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD. must be installed and transported to ensure that the coating can not be damaged or subjected to external impact, corrosion damage will lead to corrosion resistance of thermal resistance to life shortened or completely lost anti-corrosion effect.

Corrosion resistance

1, stainless steel (0Cr18Ni12Mo2Ti) protection tube: for industrial water, domestic water, sewage and other weakly corrosive media, suitable for petroleum, chemical, steel and other industrial sectors and municipal, environmental and other fields.

2, Hastelloy B protective tube: the boiling point of all the following concentrations of hydrochloric acid has good corrosion resistance, but also resistant to sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other non-chlorinated acid, alkali, non-oxidizing salt Of corrosion.

3, Hastelloy C protective tube: the ability to non-oxidizing acid, such as nitric acid, mixed acid, or chromic acid and sulfuric acid mixed medium corrosion, but also resistance to oxidation of salt Fe +++, Cu + + or other oxidants corrosion, such as high At room temperature hypochlorite solution, sea water corrosion.

4, titanium protection tube: the ability to seawater, all kinds of chloride and hypochlorite, oxidizing acid (including fuming sulfuric acid), organic acids, alkali corrosion. Intolerance of less pure reductive acids (such as quicksand, hydrochloric acid) corrosion, but if the acid contains oxidants (such as nitric acid, Fe +++, Cu ++), the corrosion is greatly reduced.

5, polytetrafluoroethylene protective tube: the chemical properties of the most stable of a plastic, boiling water, sulfuric acid, nitric acid and aqua regia, but also resistant to alkali and a variety of organic solvents. Intolerance to chlorine trifluoride, high temperature chlorination, high speed liquid fluoride, liquid oxygen, ozone corrosion.
