What does the overall objective management of pressure pipeline include?

The so-called management by objectives emphasizes the establishment and realization of objectives and requires the whole management process to serve the objectives of the organization. After determining the organizational goals, MBO decomposes the whole process of achieving organizational goals into a series of sub-goals, and ensures the realization of the overall organizational goals by ensuring the implementation of each sub-goal. The overall goal of pressure pipeline safety management is to realize the safe and economical operation of pressure pipeline. Therefore, the overall objective management of pressure pipeline can be understood as: in the design, manufacture, installation, inspection, use and maintenance of pressure pipeline and the specific working procedures of each link, determine their respective safety management objectives, and take measures to implement their respective objectives, and finally realize the overall goal of safe and economic operation of pressure pipeline.

safe

First, the safety features of pressure pipelines are low operation risk and high safety factor, and generally major accidents will not occur due to pipeline failure; Secondly, the operation is stable, and there is no or little phenomenon of running, running, dripping and leaking, which will not lead to the shutdown of pressure pipeline or frequent shutdown during the production cycle.

There are many factors that affect the safety of pressure pipeline. From the scope, it involves pipeline design, manufacturing, procurement, construction, operation, inspection and other links. In terms of time, it involves the whole time span from the initial construction period to the end of life after several years of operation.

The design equipment, design environment, design management level, design quality control level, design means of the design department and the sense of responsibility, technical level and design experience of the designers will all have an impact on the safety of the pressure pipeline. The technical level, personnel quality, production means, production equipment, production management and production quality control of the manufacturing department will also affect the quality of pressure pipelines and their components, and then affect the safety of pressure pipelines. The technical level, personnel quality, construction means, construction equipment, construction management and construction quality control of the construction department will also affect the safety of the pressure pipeline. The operation level, production management and process inspection of the operation department will also affect the safety of the pressure pipeline. Correct operation, stable operation, strengthening on-line monitoring during operation, timely protection when stopping, and strengthening detection and evaluation will all be beneficial to the safe operation of pressure pipelines.

In short, the factors affecting the safety of pressure pipeline are multi-link and multi-directional, and problems in each link and process will endanger its safety. Therefore, to ensure the safety of pressure pipeline, it must be carried out in all directions.

economy

Economy is an index to measure the one-time investment cost and operation and maintenance cost of pressure pipeline. By analyzing the composition of equipment life cycle cost, we can know that in the composition of equipment life cycle cost, although one-time investment accounts for a large proportion in the early stage of equipment life cycle, the biggest cost of equipment lies in the daily maintenance, repair and maintenance costs of the whole life cycle. Therefore, generally speaking, if the one-time investment of fully demonstrated equipment is higher, the reliability of the equipment is better, and the operation and maintenance cost in the corresponding life cycle is lower, that is, the whole life cycle cost of the equipment is lower. or vice versa, Dallas to the auditorium With the help of computer analysis, the best combination can be obtained.

The strength design of components in the whole system of pressure pipeline is an important link to reduce the one-time investment cost of the device. Piping system usually consists of many different components, which are selected according to different principles or standards. In the design, efforts should be made to ensure that all components in the pipeline system have the same strength and service life, which will greatly reduce the maintenance cost in the operation process and thus obtain better investment results.

Reducing the floor space of the device is also an effective means to reduce investment, which is contradictory to the space needed for operation, maintenance, fire fighting and pipeline thermal expansion compensation. Good design should be the best combination of the two.

While emphasizing the safety and economy of pressure pipeline, we can't abandon its basic requirements. In addition to meeting the safety and economic requirements, a good pressure pipeline should also meet the following basic requirements in design:

(1) meets the process requirements. This is the most basic requirement of pressure pipeline design;

(2) Standardized and serialized design. This will effectively reduce the manpower and material resources invested in design, production and installation, and bring convenience to maintenance, overhaul and replacement. It is worth noting that with more and more foreign exchanges, the requirements of connecting with foreign countries in design, manufacture, installation and production are getting higher and higher. Therefore, the design of pressure pipeline and the application of its standards should adopt or borrow international standards or advanced foreign standards as equivalently as possible;

(3) The design of pressure pipeline should be beautiful. Entering the petrochemical production plant, the most intuitive feeling is the layout of pressure pipes and the plane layout of equipment. A clear, beautiful and durable pressure pipeline layout is a very important index reflecting the design level.

(4) easy to manufacture and construct. This is reflected in the choice of materials should pay attention to adequate supply, and have good processability and welding performance. The structural form of pressure pipeline and its components should be feasible, and the installation environment and space should be convenient.

Working procedure of in-service pressure pipeline management

The management of in-service pressure pipeline can be divided into regular management, daily management and accident management, and each aspect has a relatively fixed working procedure. In order to achieve the overall goal of safe operation of pressure pipelines, it is necessary to formulate control procedures, grasp all aspects of safety management of pressure pipelines, and scientifically manage procedures in combination with the characteristics and requirements of specific processes.
