Winter anticorrosion of Daqing petrochemical tank
1. The winter temperature in Daqing area is basically between -10 degrees and -30 degrees, and the ice and snow fog weather is frequent. Generally, epoxy coatings have stopped the curing reaction at this temperature and cannot meet the construction requirements.
2. The oil tank has stored oil for many years, and there is more oil accumulation on the tank wall, which makes it difficult to remove completely, the adhesion of the paint film will be greatly reduced, and the anti-corrosive life will be shortened accordingly.
3. Sand blasting and derusting in winter, the humidity in the tank is large, the diffusion is not easy, and the rust is serious.
Harsh construction conditions are in front of many coatings companies. Beijing Yinfan Company, with its strong technical strength, stable product quality, and rich construction guidance experience, stands out and wins the bid; it provides high-tech anticorrosive coatings that can meet the above conditions. Product and developed a practical construction plan.
The main measures are:
1. Yinfan's winter anticorrosive series industrial coatings can meet the low temperature conditions of Daqing, have strong weather resistance, fast low temperature curing reaction, and low cost, and have achieved good results in previous use in several areas in the north.
2. Aiming at the problems of ice, snow, and fog weather, measures such as cable-stayed cloth at the top of the tank, closed construction, and heating coils at the bottom of the tank were taken to avoid ice and snow on the tank wall and ensure smooth construction.
3. Due to the large oil content in the tank wall, the sand blasting and degreasing are not thorough and the tank wall is not clean. The technicians of Yinfan can remove moisture and rust by adjusting quartz sand and river sand and covering with fine sand. The oils all achieved the desired effect.
4. With the joint efforts of Yinfan Company and related units, we have overcome many unfavorable factors and completed the anti-corrosion work of Daqing Petrochemical Company. Daqing Company was very satisfied and praised: Beijing Yinfan Company had fought another beautiful battle in Daqing anticorrosion work. (In 2007, the main workshop of Daqing Petrochemical Compound Fertilizer Plant had high acidity, complex acid-base media, severe chemical corrosion, electrochemical corrosion, and heavy rust accumulation. It was anticorrosive once a year and wasted a lot of manpower and material resources. Yinfan Co., Ltd. faced the difficulties and developed heavy anticorrosive coatings resistant to various acid and alkali media. The coating device has been running for more than three years, and the paint film is still intact. Then it was used in the winter anticorrosion of oil tanks of Daqing Refinery. Submitted a satisfactory answer.)
Daqing people said with emotion: "The technical level is different. The anti-corrosion work of petrochemical equipment is entrusted to Beijing Yinfan Company. We are assured!
