摘　　要：目前超大直径弯管的防腐作业主要采用手工操作,不仅效率低,生产成本高,而且生产过程对环境污染大。开发了一条超大直径钢制弯管自动化防腐生产线,把喷涂及自动缠带设计成一条生产线,将防腐带缠绕系统和环氧系统联动、合一,充分利用弯制余热,进行聚乙烯带缠带作业。检测结果表明,新设计的自动化防腐技术满足GB/T 23257—2017标准中超大直径弯管防腐层的要求,在防腐工艺上减少了原有预热工序,节约了能源,提高了效率,且生产过程绿色环保。At present,the anti-corrosion operation of super large diameter elbow mainly adopts manual operation,which not only has low efficiency,high production cost,but also has great environmental pollution in the production process.An automatic anti-corrosion production line for super large diameter steel bend pipe is developed.The spraying and automatic tape winding are designed as a production line.The anti-corrosion tape winding system and epoxy system are linked and integrated into a fully automatic production line.The bended waste hea is fully utilized for polyethylene tape winding.The test results show that the newly designed automatic anti-corrosion technology meets the requirements of GB/T 23257—2017 standard for the anti-corrosion coating of super large diameter bend pipe,reduces the original preheating process in the anti-corrosion process,saves energy,improves the efficiency,and the production process is green and environment-protective.
