船舶管路清洗工艺程序Flushing Technology Procedure of Piping

1、根据管路清洗图，将泵、循环药剂池和清洗管路连接好。

According to chemical flushing sketch, the pump、cycling medicament pool and chemical treatment piping must be

connected to heat coil pipes.

2、按照化学药品厂家要求，将中性除油粉、中性脱脂剂和淡水按照5%、5%、90%的比例配好，加入到临时水柜中。

According to chemical manufacturer’s requirement，dissolve the neutral deruster、neutral degrease medicament(as

attached) into clean freshwater in proportion with 5%、5%、90%.Then fill the liquid into the temporary water tank. 3、启动泵，进行循环清洗。清洗时间约为3小时。清洗时应使用木锤对清洗管路进行连续敲击，以提高清洗效率。

Start the pump, circulating cleaning water.The flushing treatment time is about 3 hours.During flushing the piping should be hammered with wooden hammer for improving the flushing effect.

4、目测检查是否有油污。如还有油污，应按照步骤3继续清洗，直到管道内壁无油污为止。

Check up with visualization if it already exits oil .If it has,repeat step3 until clean.

5、向管道内重洗加入淡水进行循环清洗（淡水中应加入一定比例的防锈剂对管道内部进行防锈处理）。原则上约为2小时，最

后将管道内的淡水全部泄放。

Refill the clean freshwater into piping and start

flushing.During flushing,dissolve the rust inhibitor(as attached) into freshwater.Normally the time is about 2 hours approximately.After rinsing,drain the piping completely.

6、使用通过压缩空气对管路吹除干燥，并向船东报检。

Blow and dry the flushing piping with compressed air.Then inspect to class and owner.
