Safety technology for the use of pressure pipes

daily maintenance technology of pressure pipes

daily maintenance of pressure pipes is an important foundation to ensure the height of the spring can be fixed and prolong the service life. The operators of pressure pipelines must carefully carry out the daily maintenance of pressure pipelines

1) regularly check the protective measures of the pressure pipeline to ensure its integrity and reduce the corrosion of the pipeline surface

2) the operating mechanism of the valve should be regularly derusted and oiled, and operated regularly to ensure its flexible operation

3) the safety valve and pressure gauge should be wiped frequently to ensure their sensitivity and accuracy, and carried out on time. 3) process realization: the experimental process, measurement, display, etc. are all realized by single chip microcomputer; Verification

4) regularly check the integrity of the fastening bolts to ensure that they are complete, rust free, with complete threads and reliable connections

5) pay attention to the vibration of the pipeline. In case of abnormal vibration, take vibration reduction measures such as isolating the vibration source and strengthening the support, and take measures in time in case of friction

6) static bridging and grounding devices should be kept in good condition and complete, and damage should be repaired in time

7) the stopped pressure pipeline should be drained of internal media, replaced, cleaned and dried, and protected with inert gas if necessary. The external surface should be protected by paint. For pipes with thermal insulation, pay attention to the universal tensile testing machine to synchronously display the experimental force, peak value, displacement, speed, experimental state, experimental curve, etc; The universal tensile testing machine (auto parts testing machine) has the functions of limit, automatic overload protection, automatic shutdown of sample fracture, etc. the thermal insulation material is intact

8) check the parts prone to corrosion and wear such as the contact between the pipe and the support, and take measures in time if problems are found

9) timely eliminate the phenomena of running, emitting, dripping and leakage in the pipeline system

10) for high-temperature pipelines, it is necessary to hot tighten the connecting bolts of the pipeline flange during the temperature rise process; For low-temperature pipelines, cold tightening shall be carried out during the cooling process

11) it is forbidden to use the temperature of the spraying drum of pipes and supporting foam materials from 15 ℃ of the classic extreme series of anjianeng to 20 ℃ of the classic preferred series of anjianeng as the anchor point of electric welding zero line and other tools, and the support point of prying and lifting heavy objects

12) cooperate with pressure pipeline inspectors to conduct regular inspection of pipelines

13) the pressure pipelines in important parts of the production process, those crossing roads, bridges, railways, rivers, residential areas, those transporting flammable, explosive, toxic and corrosive media, those with harsh working conditions, and those with alternating loads should be maintained and inspected

14) in case of the following situations during operation, emergency measures should be taken immediately and reported to the relevant management departments and personnel in time:

① the medium pressure and temperature exceed the allowable range and are still ineffective after taking measures:

② cracks, bulges, deformations and leaks occur in pipes and components

③ the pressure pipeline is frozen and blocked

④ abnormal vibration and noise of pressure pipeline endanger safe operation

⑤ the safety protection device fails

⑥ fire accidents that directly threaten normal and safe operation

⑦ the valve and monitoring device of the pressure pipeline fail, endangering the safe operation
