浅谈石油钢丝绳制造

Manufacturing oilfield wire ropes

油田作业的实际需要和厂内试验结果表明，制造石油钢丝绳应采用ＡＰＩＳｐｅｃ９Ａ规范。钢丝绳所用盘条质量应严格控制；钢丝拉拢采用８５．５％总压缩率、多道次小压缩比的变形方式；钢丝拉拢及捻股后应校直，捻纪时应有预变形器和后变形器，以消除或减小拉拔和捻制残余应力，提高其综合性能。应采用剑麻绳芯，捻股和检绳时都应淋油，钢丝绳表面脂应满足气温环境要求。

Oilfield wire ropes should be manufactured as stipulated by API Spec 9A.The quality of the wire rod should be strictly controlled; 85.5% total compression rate and small compressin ratio should be adopted in wiredrawing;both the drawn wire and the stranded wire should be straightened; the pre -deforming device and post-deforming device should be used in wire stranding to eliminate or reduce the residual stress; the sisal hemp shmp should be used as rope core, oiling should be carried out in wire stranding and twisting,and the surface grease for the wire rope should be adapted to environment temperature.
