GENERAL NOTES

1. FOR INSTRUMENTATION SYMBOLS SEE DWG NO.0005B 仪表符号参阅图DWG NO.0005B

2. FLOW DIAGRAMS ARE DIAGRAMATIC ONLY 。 ROUTING OF PIPELINES MUST BE INVESTIGATED FOR VENTING OF HIGH POINTS OF PIPING AND DRAINING OF LOW POINTS OF PIPING AND EQUIPMENT . THESE POINTS ARE NOT NORMALLY SHOWN ON P&I FLOW DIAGRAM 3. THE CONTROL VALVE ASSEMBLY WILL HAVE A 3/4" DRAIN VALVE LOCATED ON THE UPSTREAM SIDE OF THE CONTROL VALVE

在调节阀的上游应有一个3/4英寸的就地排放阀。 .

4. VESSEL INTERNALS, FURNACE COILS , HEADERS, AND

MANIFOLDS ARE SHOWN TO THE EXTENT REQUIRED FOR CLARITY.

容器内部、炉管等在必要的地方标明。

5. ALLOWANCE IS TO BE MADE FOR TEMPORARY STRAINERS IN SUCTION LINES OF ALL PUMPS AND COMPRESSOR 1 1/2" AND LARGER . "Y"TYPE STRAINERS ARE TO BE PROVIDED IN SUCTION LINES 1 1/2" AND SMALLER..

在所有泵、压缩机的吸入管线上均装有1 1/2"或更大的临时过滤器,"Y"型过滤

器则被装在1 1/2"或更小的管线上。

6. 'TO ATM AT SAFE LOCATION'MEANS 3000mm ABOVE ANY PLATFORM OR STAIRWAY WITHIN AN 8000mm RADIUS.

7. 9mm WEEP HOLE SHALL BE PROVIDED IN LOW POINTS OF RELIEF VALVE DISCHARGES VENTING TO ATMOSPHERE.

在排大气阀的低点有一个9mm的孔来排出液体。

8. BATTERY LIMIT OR ROOT VALVES ARE NOT NECESSARILY SHOWN ON PROCESS P&IDS. THESE SHOWN BE SHOWN AS REQUIRED ON DISTRIBUTION AND/OR UTILITY P&IDS DURING DETAILED DESIGN.

界区阀和根部阀在工艺流程图中不一定有,但在公用工程的P&IDS图中会有详细资料。

9. PUMP SEAL FLUSHES AND COOLING DETAILS TO BE PROVIDED BY DETAILED ENGINEERING CONTRACTOR. FOR SPECIAL REQUIREMENTS, SEE PUMP DATA SHEETS OR SCHEDULES.

泵的密封和冷却系统由工程承包商提供,有特殊要求请查看泵的曲线和表。

10. ALL ELEVATIONS SHOWN ARE PRELIMINARY, ELEVATIONS ARE TO BE FINALIZED DURING DETAILED ENGINEERING, TOWER AND DRUM ELEVATIONS ARE BASED ON REBOILER HYDRAULICS OR PUMP NPSH REQUIRENENTS.

11. BLOCK VALVES FOR ALL INSTRUMENTS SUCH AS

PLPGLI AND LG ARE NOT INDICATED AND THESE BLOCK VALVES

ARE 3/4", IF NOT INDICATED.

12. RUNNING SIGNALS FOR ALL MOTOR ARE NOT INDICATED. 所有的马达运行信号不被显示。 LINE DESIGATIONS
