Laser Welding Of Spiral Finned Tubes
Laser Welded Finned Tubes (stainless steel) imported from Germany are used in boiler reconstruction projects. Their volume is one fifth of that of traditional boilers. They cover an ultra small area. The stainless steel material is guaranteed for 15 years (compared with high-frequency welded finned tubes), and the energy saving is increased by 30%. The technology of laser welding fin tube is advanced, and the fin and tube are 100% welded, without the use of filler materials, and there are no impurities on the weld. It can be used in high-end condensing boilers, wall mounted boilers, petrochemical, power plants, nuclear power and other industries.
The use of laser welded finned tubes is one of the earliest and most successful discoveries in the process of improving tube heat exchange. This method is the most widely used method of all laser welded finned tubes to enhance heat transfer. When used, it is not only suitable for single finned tube heat exchangers, but also widely used in power, chemical, petrochemical, air conditioning engineering and refrigeration engineering.

Jin Chengju, general manager and party committee secretary of Zibo Qixiang Petrochemical Corporation, introduced that the project had a total investment of 498 million yuan. On November 18, 2007, the company laid a foundation for construction in the Qingdao Economic and Technological Development Zone, which overcomes the unfavorable delay of equipment arrival. After the situation, it took 9 months to officially start to drive on August 28 this year. Through the joint efforts of a large number of cadres and staff, it successfully opened up the whole process on September 9 to produce qualified products.
According to reports, methyl ethyl ketone is an excellent organic solvent, methyl ethyl ketone can be miscible with various hydrocarbon solvents, and has a wide range of industrial applications in tapes, synthetic leathers, coatings, adhesives and inks, perfumes, catalysts, antioxidants, and corrosion inhibitors. the use of. In addition, methyl ethyl ketone can also be used as a solvent for the dewaxing of refined lubricating oils and deoiling of paraffin waxes.
The largest production capacity of methyl ethyl ketone plant was put into operation in Shandong
The 80-thousand-ton methyl ethyl ketone plant with the largest domestic capacity for methyl ethyl ketone production, invested by Zibo Qixiang Petrochemicals Group Co., Ltd. in Qingdao, opened the process on the 9th to produce qualified products and achieved a successful drive.
