Blowing with aluminum target, Hebei dragon Asahi company specializing in the production, processing, aluminum target plate, used in blowing experiments
After the installation of the piping system, the air purge or steam sweep can be used according to the working conditions of the working medium and the degree of fouling on the inner surface of the pipe. The general requirements for pipe blowing are:
Equipment and piping that are not allowed to be purged shall be isolated from the purge system.
Pipe blowing before, should not install hole plate, flange valve, main valve, throttle valve, safety valve, instrumentation, valves and instruments for the welding connection, should be taken to remove or bypass through seals and other protective measures.
The sequence of blowing shall be carried out according to the order of the supervisor, branch pipe and drain pipe, and the blown dirt shall not enter the qualified pipeline.
Sweeping waste materials shall not pollute the environment and shall not be allowed to discharge at will.
Purge should be set before the penalty area.
No other work affecting cleaning shall be carried out after the qualified pipe blowing.
Scanning experiments with aluminum target plate, specifications and models customized according to customer demand, Liuzhou Asahi company specializing in the production of aluminum target plate, the price concessions, good quality,
1, after the strength test of the pipeline system, the purging and cleaning shall be carried out before the pressure tightness test
2, wash method should be according to the requirements of use of the pipeline, stolen degree working medium and the inner surface of the pipeline to determine the nominal diameter greater than or equal to 600mm of the liquid or gas pipeline, should adopt the artificial cleaning liquid pipe nominal diameter is less than 600mm, should be cleaned by water, gas pipeline nominal diameter less than 600mm, should be by air purge. Steam piping should be steam blown, non thermal pipes shall not be steam swept. The gas purge according to the general director, branch pipe, drainage pipe.
3, the pipeline before blowing, should prepare detailed cleaning scheme, and according to the system segments
4 do not allow purge equipment and piping to be separated from the purge system.
5, after the pipeline blowing qualified, in addition to the provisions of the inspection and restoration work, shall not be carried out in the pipe cleaning of other work, and should fill in the "pipe system flushing records."
