High Temperature & Anticorrosive Thermocouple
The operating temperature of the sulfur recovery unit is generally 1100~1400℃ , the peak temperature can reach about 1600 ℃, the corrosiveness is strong, and the H2S penetrates and corrodes at high temperature.
Our company combines the structure and use of domestic sulfur plants At present, after years of research and development, design, testing and improvement, the existing technical obstacles have been gradually solved, the import has been replaced, and the national patent has been obtained (utility model name: high temperature anti-corrosion thermocouple for sulfur recovery, patent number: ZL201220124993.X). Using direct temperature measurement (without gas protection), the service life is more than two years. It has been successfully used by more than 20 companies such as Sinopec, PetroChina, CNOOC, and Sinochem.
The company's main products include a series of instruments such as thermocouples, thermal resistances, integrated temperature transmitters, bimetal thermometers, and various pressure instruments. Sole agent of the Netherlands Thermo-electra (thermoelectric) temperature instrument, Italy ITEC pressure instrument.
By introducing and learning from foreign advanced technology and craftsmanship, the high-voltage thermocouples (CL900, CL1500, CL2500) independently developed and produced have been localized and used in national key projects: Sinopec Hainan 8 million tons/year refining project (CL1500, CL2500), Sinopec Qingdao 10 million tons/year refining project (CL900, CL1500, CL2500), Sinopec Puguang gas field purification plant (CL900, CL1500), CNOOC Huizhou 12 million tons Refining projects per year (CL1500, CL2500), CNOOC (Taizhou) Petrochemical Co., Ltd. integration projects (CL1500, CL2500); the high-temperature anti-corrosion thermocouple developed and produced in the desulfurization unit (sulfur recovery) has a service life of more than 2 years, which is a The service life of the products of similar manufacturers is 3~5 times; the service life of the wear-resistant thermocouple produced at the lifting port of the key part of the catalytic cracking unit is more than 3 years.
