Condition of the Equipment

When a problem develops on an extruder, it is important to have good information on the condition of the equipment. Extruders should be well maintained, and good maintenance records should be available so that the condition of the various components of the machine can be assessed. Maintenance recommendations from the extruder manufacturer should be followed to ensure good performance. 

Extruder screws and barrels will wear over time. The wear rate depends on many factors. Extruder screws can last for several years or only several weeks. It is impor-

Because any material may be characterized by some desirable and nondesirable properties with respect to a specific application, the selection of materials is reduced to a reasonable compromise. In so doing, one strives to select materials so that properties correspond to the basic demands determined by the function and operating conditions of the equipment, tolerating some of the undesirable properties. 

Simplified diagnostics Identification of specific failure modes of plant equipment requires manual analysis of data stored in the computer s memory. The software program should be able to display, modify and compare stored data in a manner that simplifies the analysis of the actual operating condition of the equipment. 

Monitoring the trends of a machine-train or process system will provide the ability to prevent most catastrophic failures. The trend is similar to the bathtub curve used to schedule preventive maintenance. The difference between the preventive and predictive bathtub curve is that the latter is based on the actual condition of the equipment, not a statistical average. 

A mechanical seal s performance depends on the operating condition of the equipment where it is installed. Therefore, inspection of the equipment before seal installation can potentially prevent seal failure and reduce overall maintenance expenses.

Check the onset of density wave instability in a heated channel by using a simplified model or a nondimensional plot, if the geometry and boundary conditions of the equipment agree with that of the nondimensional plot analysis (e.g., Boure, Zuber, etc.). 

Salvage value is the price that can be actually obtained or is imputed to be obtained from the sale of used property if, at the end of its usage, the equipment (property) still has some utility. Salvage value is influenced by the current cost of equivalent equipment, its commercial value, whether the equipment must be dismantled and relocated to have utility for others, and the (projected) physical condition of the equipment. Salvage value can be thought of as a cash flow that may occur several years in the future, but does not represent income for federal income tax purposes when received. 

During the dissolution test, the hydrodynamic aspects of the fluid flow in the vessel have a major influence on the dissolution rate (1). Therefore, the working condition of the equipment is of critical importance. In this chapter, the qualification and calibration of the equipment referred to in the two USP General Chapters related to dissolution, < 711 > Dissolution and < 724 > Drug Release (2), will be discussed. Sources of error when performing dissolution... 

The investigation team must realize that some of the data collected will not reflect the condition of the equipment immediately after the occurrence. Emergency response activities and post-event stabilization of the system may have altered much of the data. For example, the as-found position of every valve should be recorded. However, some valves will have been operated during emergency response or mitigation activities thus, their position at the time of the incident may not be able to be determined with complete certainty. 

Taking photographs as soon as possible after the occurrence helps to document the original condition of the equipment and site right after the incident, before post-event response activities such as site cleanup and demolition activities are performed. 

The protocol must include the proposed tentative manufacturing procedure that will be fixed at the end of the development stage. The tentative manufacturing procedure includes what kind of manufacturing equipment will be used, how the manufacturing equipment will be assembled, and how to operate the equipment. The operational condition of the equipment will be fixed at the end of the development stage. 

Inhibitor a substance, the presence of which, in small amounts, in a petroleum product prevents or retards undesirable chemical changes from taking place in the product, or in the condition of the equipment in which the product is used. 

The percentage of equipment overdue for inspection can be considered a leading metric as it can relate to the physical condition of the equipment as well as the robustness of the inspection program (and, by extension, indicate a gap in the safety culture). Of course, even if inspections are routinely conducted and recorded as a leading metric, a failure can still occur. This reinforces the need for multiple process safety metrics to address positive signs of systems working well or... 

Frequent liquor losses from the system, acting for all practical purposes as a frequently used purge stream, did not allow the examination of the full co-precipitation potential of the process. These liquor losses were the result of numerous piping and pump leaks and insufficient surge capacity. The poor condition of the equipment following three years of inactivity and a limited recommissioning were responsible for leaks and numerous other mechanical problems. Excessive inputs of seal water (needed to maintain worn out pumps in operation) combined with heavy rains and very limited surge capacity caused severe system volume balance problems. 

Both the pilot plant and the prototype tests have demonstrated the excellent SO2 control capability of the technology. SO2 removal efficiencies in excess of 95% have been consistently achieved. The use of finely ground limestone is necessary, but at the same time the limestone utilization is quite good—well in excess of 95%. Reasonable soda ash makeup rates were established in the pilot plant tests but could not be verified at Scholz due primarily to the poor mechanical condition of the equipment. 

For each method of sterilization it is important to initially define the different parameters which guarantee a biologically effective sterilization value, according to actual operating conditions of the equipment. 

The condition of the equipment to be used meets the specified requirements.

However, there are potential risks associated with using bamboo as a polymer source for rayon since there is currently a lack of transparency in the supply chain. It is not always clear which type of bamboo is used for fibre, where it is grown, how it is cultivated, how it is harvested, and so forth. To date, there is no known organic certification of bamboo. The process to make bamboo viscose rayon fibre is the same process that is used to produce viscose/rayon from any other plant source. The cellulose is extracted from the bamboo and then mixed with chemicals to convert the plant pulp into textile quality fibre. This process can be very polluting unless it is carefully controlled, and can be influenced by the age and condition of the equipment as well as by whether there is any by-product recycling or effluent treatment. Note that in most countries the fibre cannot be called bamboo, only rayon or viscose from bamboo (textileexchange.org). 

The risk of each equipment item should be projected at the end of life extension period. The assessment of the future condition of the equipment item should be done based on the current risk values, defined inspection, maintenance and mitigation plan, and predicted operating condition of the item within the life extension period. It should be noted that in order to project the risk value, we assume that all planned inspections and maintenances will be followed. 

Inspection or testing conducted on equipment to detect impending or minor failures and restoring the proper condition of the equipment. 

This can become possible by stody of the actual operating conditions of the equipments and comparing them with design/recommended conditions (temperature, pressure, flow rates, etc.). 

In case of continuous operation the load of the equipment is perpetual, uniform and frequently subnominal during the analysed period (Ta). In this case, the reliability analysis refers to Ta period and starts with the recalculation of X intensity of failure indicator for the specific operation conditions of the equipment/ i subsystem (Felea, I. 1996). 

The vertical relation of the top and bottom knives is also an important factor in producing a quality slit edge. The correct vertical position depends on the strip gauge, its tensile strength, and the condition of the equipment. The horizontal clearance is also important in setting the vertical position. If the horizontal clearance is too tight or too loose, more vertical overlap will be needed to separate the strip, which can lead to problems (Fig. 6). 

If the driver is not satisfied with the condition of the intermodal equipment, the driver is to notify the intermodal equipment provider of the condition of the equipment and not use the equipment until it has been repaired. 

External auditors pass through looking for the correct color tape, not the condition of the equipment. Amazing The whole process was developed to increase inspection of the equipment and the result is exactly the opposite. Now the correct color tape, not the condition of the equipment, is the pass/fail indicator.
