China Petrochemical News Network reported this year, Jinling Petrochemical gave full play to its professional advantages, through comprehensive inspection of hidden pipeline hazards, implementation of equipment technical transformation, and preventive maintenance measures, to grasp equipment safety management to ensure the stable operation of summer installations
.
"Drag the net" to eliminate the risk of pipeline inspection
Since the beginning of the year, the company’s Mobility Department has organized personnel to conduct a comprehensive investigation of all riverside pipeline corridors, system pipeline networks, and pipelines crossing communities in the region
.
At present, a total of 6,266 problems have been detected through investigation of pipe support displacement, pipeline buried soil flooding, pipe frame damage, corrosion thinning, weld defects, and insulation and corrosion protection failure.
Rectification
.
At the same time, professionals use pulse eddy current technology to scan the equipment and process pipelines
.
At present, the inspection of 254 pipelines of Ⅱ Atmospheric and Vacuum, Ⅲ Diesel Gas, Catalytic Slurry and other installations has been completed, and problems such as 46% thinning of the inlet elbow of the catalytic slurry raw material have been discovered in time, and the risk has been eliminated by immediate disposal
"Technical Transformation" Improves Equipment Reliability
This year, the company improved the reliability of equipment operation through technological transformation
.
Use the maintenance opportunity to upgrade the old central control DCS of boiler II and boiler VI to improve system reliability
Improve the machine-pump group monitoring system, introduce seal monitoring into DCS monitoring, configure remote shut-off valves for inlet and outlet valves, and try to solve the problem of “big horse-drawn carts” of machine-pumps to help the efficient and safe operation of power equipment
.
At the same time, the use of carbon steel tube bundles for more than 2 cycles (8 years), stainless steel tube bundles for more than 3 cycles (12 years), and more than 10% of the leaky tube bundles are uniformly reported for update, reducing the failure rate of cold exchange equipment
.
"Prevent" maintenance to prevent the effects of high temperature thunderstorms
The company promotes preventive maintenance work to eliminate potential hazards and risks in advance to ensure production safety
.
At present, the company cleans more than 550 heat exchangers in advance to ensure that it meets the summer process requirements and safe production
.
The grounding resistance and lightning protection device testing was completed, more than 15,480 grounding electrical points were tested, and all unqualified points were rectified
At the same time, strengthen the live monitoring of equipment in transit, carry out regular infrared inspections, and carry out ultraviolet inspections on 110/220kV terminal heads to observe the discharge size, position and form of power equipment more sensitively and intuitively, and provide reliable equipment for healthy operation and defect diagnosis.
