Production of alloy high pressure target plate device

The general requirements for pipeline purging are:

Equipment and piping that do not allow purging shall be isolated from the purging system.

Before piping purging, orifice plates, flanged regulating valves, main valves, throttle valves, safety valves, instruments, etc., shall not be installed. For the above valves and instruments connected by welding, protective measures such as passing through the bypass or removing seals shall be taken.

The purging shall be carried out in the order of main pipe, branch pipe and drain pipe, and the blown dirt shall not enter the pipeline qualified for purging.

The dirty things discharged by purging shall not pollute the environment, and it is strictly prohibited to discharge at will.

Restricted area should be set before purging.

No other operations affecting the cleaning shall be carried out after the pipeline is blown up to the standard.

Aluminum target plate for purge experiment, specifications and models customized according to customer demand, Longxu company specializing in the production of aluminum target plate, price concessions, good quality

1. After the strength test of the pipeline system, purge and cleaning shall be carried out in stages before the air pressure tightness test

2, purge method should be in accordance with the requirements of the use of pipeline, working medium and the pipe inner surface of stolen property, extent determine the nominal diameter greater than or equal to 600 mm of liquid or gas pipeline, appropriate USES artificial cleaning, liquid pipe nominal diameter less than 600 mm, appropriate USES water to clean, nominal diameter less than 600 mm of gas pipeline, appropriate USES air purge. Steam pipe should be used steam purge, non - thermal pipe shall not use steam purge. The purge gas is generally carried out in sequence according to the main pipe, branch pipe and drain pipe.

3. Before blowing and washing of pipelines, a detailed blowing and washing scheme shall be prepared and carried out in stages according to the system

4. The equipment and pipelines are not allowed to be separated from the blowing and washing system.

5. After pipeline blowing and washing is qualified, other work affecting internal cleaning shall not be carried out except the prescribed inspection and restoration work, and "Pipeline System Blowing and washing Record" shall be filled in.
