PIPING CLEANING PROCEDURE 管路清洗工艺

1. General :总则 总则
This specification describes the cleaning procedures for various types of piping material & systems SO17020 SBM CALM BUOY for SCARABEO 9-H189 Project. 本规格书描述了 SCARABEO 9-H189 项目中各种管材&系统的清洗工艺。

2. Procedures:工艺 工艺
The cleaning procedures are for: 本清洗工艺适用于: Carbon steel pipes ASTM A106 Gr.B or equal. 碳钢管 ASTM A106 Gr.B 或同等级管材。 Stainless steel pipes, stainless tubing and carbon steel tubing. 不锈钢管,高精密不锈钢管
和高精密碳钢管。

Notes: The basic and detailed steps which are applied refer to Table 4.1 “Cleaning Requirem ent”. 管子串油清洗详细步骤参考表 4.1“清洗要求” a) Air Purge 空气清洗 Pipes shall be blown with dry filtered air until no traces of debris or liquid. 用干燥过滤过的空气吹洗管子至无残渣及液体。 b) Chemical Flushing 化学冲洗 Degreasing: Circulate a degreaser to remove oil and grease. Then flush out the system with fresh water until no trace of degreaser is detectable. 去油:用去油剂循环冲洗除去油脂。然后清水冲洗至没有去油剂。 Descaling: Circulate at ambient temperature with a solution containing 6 to 8 % Inhibited Hydrochloric Acid or other equivalent compound to remove all iron oxides and mill scales from the surface of pipes. 除锈:常温下,用 6-8%盐酸溶液或等同化合物除去管子表面 的铁锈及氧化皮。 Then flush out the system thoroughly with fresh water until neutral pH is achieved (pH6 to 7). 用淡水彻底冲洗至 PH 值达到中性(PH6 到 7) 。 c) Oil Flushing 串油 By mean of gear pump and filter (5 micron), the pipes are to be flushed with flushing oil (Shell, BP, Chevron or equivalent) for about 4hours. 用齿轮泵和滤器(5 微米)对管子进 行串油约 4 小时(Shell, BP, Chevron 或等同品牌) 。 The filters are to be cleaned or changed hourly or less as required. 滤器应至少每小时清洗 或更换一次。 All joints shall be hammered to assist the cleaning of these places. 敲打所有的接头以帮助 清洗。 d) Hot Oil Flushing 热油串洗 Lines shall be hot oil flushed with same type of oil or similar as the system to be operated. 用与系统用油相同的油进行热油冲洗。 During the flushing operation, oil samples will be taken every 4 hours or as required. 100ml of hydraulic oil shall be running through out oil sample filter. 串油时, 4 小时 每 或按照要求进行取样。100ml 液压油流过取样滤器。 The sample filter shall be compared with the master slide. When the sample is similar or better than the master slide, hot oil flushing shall be stopped.

PIPING CLEANING PROCEDURE 管路清洗工艺

取样滤器和标准样例进行对比。如果取样结果近似或优于标准样例,则停止串油。 Minimum hot oil flushing time is 6 to 8 hours. 串油最少要进行 6 到 8 小时。 Hot oil temperature shall be approximately 40 to 70 degree C. 热油温度大约为 。 SO17020 SBM CALM BUOY 40-70 C Lowest flow of hot oil is calculated for actual pipe as follows: 最小流量按下式计算 KxQ Re = ------------Vxd Where: Re K Q V D = = = = = Reynold number. 雷诺系数 Constant, 21220 to be used. 常量 Flowrate (litre/min.). 流量 Viscosity (Centistoke). 黏度 internal diameter of pipe (mm). 管子内径

Reynolds number shall be minimum 4000 to guarantee turbulence flow to all places in pipe. 雷诺系数最小取 4000,以保证管内所有区域都为紊流。 Note: For systems which NAS Class requirement is worse than NAS1638 Class 8 and pipe material is SS, connection type is Butt-weld, no need hot oil flushing. 对于要求低于 NAS1638 8 级、管材为不锈钢且连接形式为对焊的系统,不需要串油。

3. Inspection & Records 检查 记录 检查&记录
Site inspection shall be carried-out progressively.现场检验应逐步进行。 Final acceptance to be signed by Owner representative. 最终验收结果需要经过船东代表签 字。 Hydraulic pipes flushing cleanliness shall be recorded by calibrated test recorder and included to the final report to owner. 校准试验记录员记录液压管串洗清洁度,和最终报告一起交给船 东。
