Inspection and Preventive Maintenance

By performing weight loss tests, technical personnel can estimate the corrosiveness of an environment over a period of time. If the corrosion rate is determined to be high, preventive measures can be taken to prolong the remaining life of the equipment. The preventive measures can include the addition of a corrosion inhibitor, a change in the process, an application of anticorrosion coatings, or the addition of a CP system. 

An additional and simplest and obvious method to monitor the corrosion rate is through visual inspection of all parts of the equipment that are exposed to corrosive 

Regular periodic inspection is performed as part of maintenance program in plants. The results of the inspections are used to plan equipment repairs during scheduled shutdowns and to take action to maintain optimum production quality and quantity.

As with any power equipment, gas turbines require a program of planned inspections with repair or replacement of damaged components. A properly designed and conducted inspection and preventive maintenance program can do much to increase the availability of gas turbines and reduce unscheduled maintenance. Inspections and preventive maintenance can be expensive, but not as costly as forced shutdowns. Nearly all manufacturers emphasize and describe preventive maintenance procedures to ensure the reliability of their machinery, and any maintenance program should be based on manufacturer s recommendations. Inspection and preventive maintenance procedures can be tailored to individual equipment application with references such as the manufacturer s instruction book, the operator s manual, and the preventive maintenance checklist.

Inspection and Preventive Maintenance T/F Inspection and preventive maintenance were in accordance with applicable procedures, manufacturer s or experience-based recommendations and governing standards, and were adequate for the service conditions. 

Inspection and Preventive Maintenance As with all water-based extinguishing systems, particularly those installed outside, inspection and preventive maintenance are critical to reliable operation. Detection devices are typically inspected, tested, and maintained quarterly or at a frequency deemed more appropriate for a particular location. The water-spray system itself is typically flow-tested at least annually (NFPA 25, 1995). Because of the nozzles small orifice size, scale and corrosion buildup can compromise flow and spray patterns. The use of strainers and the conduct of flow tests will help minimize this potential problem. As stated earlier, preventive maintenance of the overall water supply and distribution systems is an integral part of a reliable system. 

Inspection and Preventive Maintenance When a steam curtain is to be used to mitigate the consequences of a flammable material release, it must be treated as if it were part of the site s firefighting system. This means that a managerial system must be in place to ensure that the steam curtain system is inspected periodically. Deficiencies should be reported and repaired promptly. Follow-up investigations must be made to ensure that the inspections, deficiency reporting, and repairs occur in a timely manner. If the system must be shut down for the repairs, the same procedures that would be followed for a sprinkler or deluge system shutdown should be utilized. 

Indicators may be used to provide an objective, accurate measurement of the different services provided in the department. These can measure specific individual, team, and departmental performance parameters. Typical indicators might include simple tallies of the quantity or level of effort for each activity, productivity (quantity/effort), percentage of time spent performing each activity, percentage of scheduled IPMs (inspection and preventive maintenance procedures) completed within the scheduled period, mean time per job by activity, repair jobs not completed within 30 days, parts order for greater than 60 days, etc. 

In test case C2 corrective maintenance, inspections and preventive maintenance are performed on a two-unit system in a cold standby configuration. Each unit is affected by two degradation mechanisms and can fail due to two different failure modes. 

The Maintenance Department is responsible for keeping all vehicles and equipment safe and functioning properly through a systematic and proactive schedule of inspection and preventive maintenance, service, and repair. 

Equipment inspections and preventive maintenance conducted as scheduled. 

In order to achieve effective, safe, and reliable operation of all equipment in the inventory, the hospital uses interval-based inspections and preventive maintenance, corrective maintenance, or metered maintenance strategies. Model-specific strategies and preventive maintenance procedures developed for this equipment based on the risk stratification, the AHA Manual for Medical Equipment, manufacturer guidelines, and NFPA or ANSI standards. 

Clinical engineering defines the time intervals based on manufacturer s recommendations, risk levels, and current hospital experience. Clinical engineering uses the AIMS database to define and maintain the preventive maintenance and inspection intervals on appropriate equipment in the inventory, automatically generating interval-based inspection and preventive maintenance work orders monthly. 

Make sure that piping and equipment inspections and preventive maintenance tasks are completed as required to ensure mechanical integrify of process equipment. Containment of fuel is the best way to prevent vapor cloud explosions. Ignition sources forflammable vapor clouds for example, heaters, vehicles, unclassified electrical areas, hot work, static discharge — are difficult to control.

A formal record is desirable for every inspection and preventive maintenance job. If the work is at all detailed, a checklist should be used. The completed checklist should be returned to the maintenance office on completion of the work. Any open preventive maintenance work orders should be kept on report until the supervisor has checked the results for quality assurance and signed off approval. Modem computer technology with handheld computers and pen-based electronic assistants permits paperless checklists and verification. In many situations, a paper work order form is still the most practical media for the field technician. The collected data should then be entered into a computer system for tracking. 

Reactor maintainability. The reactor plant operating experience has demonstrated quite acceptable maintainability of the integral LMFR. There have been no additional difficulties in repairing primary system components on BN-600 compared with BN-350. Repairs of the reactor equipment items and sodium systems, including such complicated operations as replacement of the reactor coolant pumps and SG modules, re-arrangement and jacketing of primary sodium systems, extraction of distorted items from the reactor core, etc. had virtually no influence on the duration of planned outages, which were defined, as a rule, by inspections and preventive maintenance of the steam-water system components. 

Optimizing the inventory level of spare parts is an important stage in order to reduce downtime, especially for parts that have very long lead or turnaround time. After the inspections and preventive maintenance have been optimized, the requirement for spares is modified and should be also optimized. For that purpose, we use the spares optimization module of the ApmOptimizer. The optimization algorithm objective is to minimize the total costs and damage. The program provides the optimal initial spares quantity as well as the required spares that must be ordered during lifetime in order to replenish stocks of condemned parts.
