- 摘要:
- PIG机械清洗技术已经在中原油田的污水管道、集输管道以及城市供水管网的清洗中得到应用，但其能否用于结垢严重的高压注水管道的清洗则尚未见诸报道，为此进行了以PIG清洗为主、化学软化清洗为辅的联合清洗现场试验，结果表明，除垢率达98%，可达到旧管道内衬修复的要求。
The PIG mechanical washing technology has been applicated in washing of drainage pipeline，gathering pipeline and city water supplying network. However it is not seen in public report thatthis technology can be used for washing of high pressure injection water pipeline with heavy scal-ing. Therefore a field washing test has been carried out by means of PIG mechanical washing withauxiliary chemical soft washing. The result shower that percentage of scaling disposal is up to98%which is satisfied for requirement of liner reparing of used pipeline.1997,3(3): 10-11 收稿日期：1996-10-14
