In order to ensure the normal use of the steam pipeline, flushing and flushing is required before the pipeline is put into work. The following is a professional steam pipe manufacturer to introduce the precautions in the purge process.
Ready to work:
Install the same temporary exhaust pipe for flushing pipe as the steam nozzle, lead it to the outdoor, and tilt it up to the air (can also be set according to the site) A white marker band surrounds the flushing tube area, is equipped with communication equipment, and arranges lighting facilities. Check the firmness of the entire pipe support and properly strengthen it. The personnel participating in the flushing tube clearly define the division of responsibilities and do the job. Special person responsible and under the instruction of the rushing pipe command.
Purge process:
1 Warm pipe: Slowly open the air intake valve and open all the traps at the same time. When steam appears at the trap, adjust it to the slightly open state. When the discharge port of the flushing pipe emits steam, it is stable for a certain time.
2 Constant temperature: The purpose is to make the pipe fully expand and stretch, and at the same time can reflect the stress conditions such as thermal expansion displacement.
3 purge: no abnormal phenomenon in the constant temperature stage, you can slowly increase the gas volume, boost the flushing tube
4 times: according to the steps of temperature reduction → warming pipe → constant temperature → boosting flushing tube, the larger the temperature difference, the better the quality of the flushing tube, and the number of flushing tubes is determined by the cleanliness of the airflow of the flushing tube.
Check perfect:
1 When the flushing tube is over, open the drain valve and release the pressure and exhaust steam.
2Remove the exhaust pipe, install heat and connect the household outlet, perfect the entire pipeline installation
