摘　　要：海洋石油工程开发海底管道的ERW钢管,通常从国外进口,进口ERW海管材料价格昂贵,交货期很长,手续繁琐。提升国产化ERW钢管制作工艺,解决高频焊缝的熔融技术,使其达到海管技术要求,满足海管的标准是关键环节。通过对钢板卷生产和ERW钢管生产厂家的生产能力和技术水平进行调研和评估,通过试制和小批量试生产,优化ERW钢管制造工艺和技术,使得ERW钢管技术指标符合海管要求,并首次应用国产ERW钢管作为海管。经过实际生产运转检验证明,国内ERW钢管可以应用于海底管道。ERW steel pipe used as submarine pipeline in offshore oil engineering usually imported from abroad. Import ERW sea pipe materials are expensive, long delivery time, cumbersome procedures. Improving production technology of national ERW steel pipes to solve the melting technology of high frequency welding, reach the sea pipe technical require ments and meet the sea pipe standard are the key links. Trial and small batch production was based on the investigation and evaluation of the steel strip plant and ERW pipe manufacturers capacity and technical level. The ERW steel pipe specifications meet the requirements of sea pipe by optimization of ERW steel pipe manufacturing process and technology, and for the first time the application of national ERW steel pipe as submarine pipeline. Practical have proved the national ERW pipe can be used in submarine pipeline.
