The No. 4 cracking furnace of Sinopec's million-ton ethylene plant used a new type of anti-coking aluminum-containing superalloy furnace tube for the first time, and successfully completed the first 130-day operating cycle, which was twice as long as the original furnace tube scorching cycle. Judging from the inspection of the first operating cycle after the application of the new furnace tube in the No. 4 cracking furnace, the effect of the application of the new furnace tube is remarkable.
In order to ensure that the replaced furnace tube meets the target requirements of good anti-coking performance and long-term operation, the project team of Sinopec Corporation finally decided to adopt the research and development of QDXL Industrial Tube Technology Corporation. and obtained the national invention patent authorization and anti-coking performance. The advanced new type aluminum-containing high-temperature alloy furnace tube, which contains higher aluminum content than the old furnace tube, has a smaller catalytic coking effect on the surface of the furnace tube, a more uniform heat flux distribution, and a higher heat transfer coefficient. It is completely resistant to oxidation at a high temperature of 1200°C, which can effectively extend the operating cycle of the cracking furnace.
The aluminum-containing superalloy furnace tube is the first of its kind in China. The product has been successfully applied to important first (set) sets of equipment, which will help transform scientific and technological achievements into productivity and promote the development of furnace tube material application in China's ethylene cracking industry.
About QDXL
QDXL Industrial Tube Technology Corporation is a leading manufacturer specializing in centrifugally cast high-temperature alloy tube and static castings.
The products include ethylene cracking furnace tubes, reformer furnace tubes, CAL(continuous annealing lines) &CGL(continuous galvanizing lines) furnace rollers and radiant tubes, glass lehr rollers and heat/wear resistant castings. The annual capacity is 9000 tons centrifugal castings and 3500 tons static castings (500 tons precision castings). The cast products have been widely used by many international petrochemical, engineering and metallurgy companies.
In 2011, in order to increase manufacturing capacity, a new plant was built based on the experience from the previous two plants using the latest technology and new equipment designs.
Most of them have been in the heat resistant furnace roller and tube industry for over 30 years and have contributed to the development of materials for ethylene cracking furnace, hydrogen reformer furnace, steel strip continuous annealing lines and continuous galvanizing lines and float glass lines in China Most of the management and technicians have more than 30 years experience of manufacturing heat resistant alloy centrifugal and static castings. The accumulated rich experience and valuable technological knowledge have resulted in the development of our own patented technology and knowhow.
