中石化第十建设公司承建的齐鲁30万吨/年乙烯装置,1991年5月被中国工程建设焊接协会评为优秀焊接工程。齐鲁乙烯工程30万吨/年乙烯装置由日本引进。焊接工程量主要有工艺配管和管道278929米;金属结构61 00吨;工艺设备800台,其中球罐16台,裂解炉8台,超高压蒸汽锅炉2台。装置总投资为39098.77Y元。由于装置工艺设计复杂,进口材料牌号,规格繁多,焊接工程量浩大,特别是低温钢和高温合金的焊接难度较大。该公司在独家承建乙烯装置的情况下,明显
Sinopec Tenth Construction Company contracted Qilu 300,000 tons / year ethylene plant, in May 1991 by the China Construction Welding Society as outstanding welding works. Qilu ethylene project 300,000 tons / year ethylene plant imported from Japan. There are 278929 meters of process piping and pipes; 6100 tons of metal structure; 800 sets of process equipment, including 16 spherical tanks, 8 cracking furnaces and 2 sets of EHV steam boilers. The total investment for the device is 39,098.77Y yuan. Due to the complicated process design of the device, the imported material grades, specifications are numerous, the welding works are huge, especially the welding of the low-temperature steel and the high-temperature alloy is difficult. The company is clearly in the case of exclusive construction of ethylene plant
