Target Plate For Pipe Purging Aluminum Target Plate For Flushing Pipe
The operation of introducing pressurized gas or liquid to remove rust, welding slag, dirt and other impurities in the pipeline system is referred to as pipeline cleaning. ...The purging effect of the medium and high pressure steam pipes is checked with the aluminum target plate installed in the exhaust pipe. The impact marks on the target board visible to the naked eye are not more than 10 points, and each point is not more than 1mm as qualified. The purging effect of general steam pipes or other pipes...
Steam purge
1. Steam purging is suitable for conveying power steam pipelines or
thermal pipelines. Non-thermal pipelines are not suitable for steam
purging because heat expansion and other issues are not considered
in the design.
2. The steam purge should be purged with a large flow of steam, and
the flow rate should not be less than 30m/s.
3. Before steam purging, the pipes should be heated and drained in
time to check the thermal displacement of the pipes.
4. Steam purging should be carried out by steaming-slowly rising
warm tube-constant temperature for 1h-purging-stopping air to cool
down-reheating pipe heating, constant temperature, second purging,
such repetition is generally not less than 3 Second-rate.
5. Medium and high pressure steam pipes and steam turbine inlet
pipes should be inspected with flat and clean aluminum target
plates and wooden target plates for low pressure steam. The target
plate is placed at the steam outlet and the target plate is
qualified if there is no dirt.
| Aluminum target plates for scanning experiments, specifications and models are customized according to customer needs, Zexu company specializes in producing aluminum target plates, with favorable prices and good quality. |
| 1. After the strength test of the piping system, before the air pressure tightness test, purge and clean should be carried out in sections |
| 2. The method of purging should be determined according to the requirements for the use of the pipeline, the working medium and the degree of stolen goods on the inner surface of the pipeline. Liquid or gas pipelines with a nominal diameter greater than or equal to 600mm should be manually cleaned. Liquid pipelines with a nominal diameter less than 600mm should be cleaned manually. Use water to clean the gas pipeline with a nominal diameter of less than 600mm, which should be purged with air. Steam pipes should be purged with steam, and non-thermal pipes should not be purged with steam. The purge is generally carried out in sequence according to the main pipe, branch pipe, and drain pipe. |
| 3. Before the pipeline is purged, a detailed purging plan should be prepared and carried out in sections according to the system |
| 4. The equipment and pipes that are not allowed to be purged are separated from the purging system. |
| 5. After the pipeline is qualified for purging, in addition to the prescribed inspection and restoration work, no other work that affects the cleaning of the pipeline shall be carried out, and the "Pipe System Purging Record" shall be filled in |
