After the piping system is installed, it can be blown by air or steam according to the working conditions of the working medium and the degree of dirt on the inner surface of the pipe. The general requirements for pipe purge are:
Equipment and pipes that are not allowed to be purged should be isolated from the purging system.
Before the pipeline is purged, orifice plates, flange-connected regulating valves, main valves, throttle valves, safety valves, instruments, etc. should not be installed. For the above-mentioned valves and instruments connected by welding, the bypass should be used or the seal should be removed. Protective measures such as pieces.
The order of purging should be carried out in the order of main pipe, branch pipe, and drain pipe. The blown out dirt must not enter the pipes that have been purged.
The dirt discharged by purging shall not pollute the environment, and random discharge is strictly prohibited.
A restricted area should be set before purging.
After the pipeline has passed the purging, other operations that affect the cleaning shall not be carried out.
The aluminum target plate for scanning experiment, the specifications and models are customized according to customer needs, Longxu company specializes in producing aluminum target plates, the price is favorable, and the quality is good.
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 required inspection and restoration work, no other work that affects the cleaning of the pipeline shall be carried out, and the "Pipeline System Purging Record" shall be filled in.
| 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 according to steam-slowly rising warm tube-constant temperature 1h-purge-stop air to cool down-reheat the pipe heating, constant temperature, first purge, such repetition is generally not less than 3 times. |
| 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. |
