Which oil and gas demand is suitable for steam pipeline valves to drive pipeline market safety and environmental protection need to be protected by law

Suitable for steam pipeline valve temperature is less than 425℃ basically can choose: gate valve, cut-off valve. Choose alloy valve above 400℃. The gate valve is mainly used for the main steam valve in the steam pipeline, that is, the valve that is not often switched on and off. Globe valve is mainly used for users close to the valve equipment, because this valve has a good regulating effect on the flow.

Globe valve is mainly used for users close to the valve equipment, because this valve has a good regulating effect on the flow.
Steam pipeline selection valve is mainly to see the temperature, pressure, function and installation position.
Can butterfly valves be used on steam pipes?
If used for steam pipeline, it is not recommended to use butterfly valve, because the pressure in the butterfly valve is large, the switch is difficult to operate, easy to damage the sealing surface, so can not be frequently switched on and off, in performance as the gate valve;
However, if the pipeline pressure is not very high (below 6.4mpa), it can also be used, but because of the high temperature, it is recommended to use metal hard seal butterfly valve, can choose the eccentric butterfly valve of the body WCB, should pay attention to the flow direction when installing, the pipeline should be kept clean as far as possible, to prevent welding slag stuck in the sealing surface, easy to close loosely.
Oil and gas demand drive pipeline market safety environmental protection with law protection, as our demand for oil and gas is increasing, the construction of pipeline is always in the sustained growth period. Due to the characteristics of high pressure, inflammable and explosive medium and sensitive environment of oil and gas pipeline, the safety and reliability of pipeline transportation is of particular concern. Pipeline risk identification and control are facing urgent problems. It has become urgent to build a legal defense line to protect pipeline safety with the thinking of rule of law.
Oil and gas demand drives the pipeline market safety and environmental protection needs to be protected by law
Along with the sustained and stable development of Chinese economy and the continuous improvement of people’s living standard, the demand for oil and gas is also increasing, and the construction of Chinese pipeline has been in a sustained growth period. As a result, the risks of pipeline safety and environmental protection are also increasing.
Under the development strategy of one Belt and one Road in our country, the mileage of oil and gas pipelines operation will become more and more long, safety and environmental protection risk will also become greater. How to ** is a problem that managers must face.
The rapid development of oil and gas pipelines
According to the data disclosed so far, China had 106,000 kilometers of oil and gas pipelines by 2014, with more than 70 percent controlled by petrochina, Sinopec and CNOOC. It is expected that by the end of 2015, China’s oil and gas pipelines will reach 150,000 kilometers, and a complete domestic and foreign pipe network system will be formed.
In general, Chinese crude oil pipeline network began to take shape. The crude oil backbone pipe network has been basically formed, and regional pipe networks have been further optimized. China’s crude oil pipeline network layout to the northeast, northwest, North China, East China, southwest, coastal and coastal areas of the crude oil reserve facilities as a link, covering the country’s main refining and chemical enterprises and reserve bases, crude oil pipelines are concentrated in the border ports and coastal ports, northeast, northwest oil areas and southwest, North and East China.
In recent years, with the rapid development of Chinese economy, the demand of refined oil is high, and the networking trend of refined oil is also strengthening. A refined oil pipeline network with refineries, refined oil transfer depots and storage depots as the backbone for the consumer market has been formed throughout the country. It is expected that by the end of the 12th Five-Year Plan, the length of China’s refined oil pipelines is expected to exceed 30,000 kilometers.
Meanwhile, the construction of natural gas pipeline is also developing rapidly. At present, the backbone pipeline network of natural gas has been preliminarily formed.
In addition to onshore pipelines, China has built relatively large subsea oil and gas pipelines, including Jinzhou 20-2 condensate gas field to onshore submarine pipeline, Boxi gas field to Tianjin submarine pipeline, Bohai Suizhong 36-1 offshore oil field to onshore submarine pipeline, etc.
At the same time, China-Kazakhstan crude oil pipeline, Central Asia natural gas pipeline, China-Myanmar oil and gas pipeline, China-Russia crude oil pipeline and Southeast Sea passage, which are several major transnational energy pipelines, also connect domestic and foreign oil and gas resources more closely.
Pipeline safety and environmental protection presents new problems
Oil and gas pipelines are characterized by high pressure, inflammable and explosive transport medium, and sensitive environment. The random digging and construction along the pipeline and the third party damage seriously affect the safe operation of oil and gas pipelines, and bring serious threats to the safety of life and property of the owners of illegal buildings and illegal construction workers.
Therefore, with the rapid development of pipeline industry in China, the safety and reliability of pipeline transportation is of particular concern, and the risk identification and control of pipeline faces the urgent problem to be solved. From the current point of view, the overall situation of pipeline safety protection is getting better. But some problems cannot be ignored, there are mainly the following aspects.
One is the serious situation of drilling and stealing oil. Some cases of oil theft show the new characteristics of intellectualization and specialization. Shandong Province, Hebei and Liaoning are still high incidence areas.
The second is the importance of optical cable protection. Pipelining communication cable is the cornerstone of remote control and digital management of oil and gas pipeline network. With the production of newly built pipelines in recent years, the influence of cable breaking on the production and operation of pipeline enterprises is more and more prominent.
Third, the urgency of cleaning up the pipeline load.
Fourth, the complexity of third-party construction monitoring management. With the rapid development of national economic construction, engineering construction along the pipeline is increasingly frequent, and the number of all kinds of cross construction *** rise.
The pipeline company the personage inside course of study thinks, from the perspective of the pipeline safety and environmental safety pipeline safety mainly face several risks: urban planning and construction, manufacturing and construction defects, pipeline corrosion, aging, process run wrong operation, punching bunkering, the third party damage, third party construction, pipe tie up, natural disasters, etc.
According to these, pipeline managers must be prepared to risk identification and control, sets up the accident can be prevented, the concept of risk can be precontrol, using scientific tube body test, environment test, risk evaluation, risk identification methods, such as through scientific and reasonable method of pipe repair, maintenance, and improve the emergency management, and other means, item by item, control risk, The pipeline risk can be controlled within an acceptable range.
Establish the legal thinking of oil and gas pipeline
Applying legal thinking and legal way to protect pipelines and constructing pipeline protection mechanism under the legal framework are the essential meanings of the rule of law. In particular, it has become urgent to build a legal defense line with the rule of law thinking.
The Special Equipment Safety Law, which came into effect on January 1, 2014, has included long-distance transportation pipelines into the management scope of special equipment, and set higher requirements for pipeline installation, testing, registration, use, inspection, supervision and management and emergency rescue. The Work Safety Law, which came into effect on December 1, 2014, includes the implementation of the work safety responsibility system in the scope of supervision and assessment, establishes a system for identifying and dealing with hidden dangers, and increases penalties for violations. The Environmental Protection Law, which came into effect on January 1, 2015, has improved 10 environmental protection systems for enterprises and public institutions, and put forward higher requirements for accident prevention and emergency disposal of pipelines.
It is rare in the history of China to enact and implement relevant laws against enterprises at such high density. The time has come for China to govern enterprises according to law. However, there is still a lot of work to be done before relevant laws can be put into practice, and the legal pipeline still has some way to go.
Under the legal background, pipeline safety production should adhere to the principle of safety, prevention first and comprehensive management. To improve rules and regulations, rely on scientific and technological progress, strengthen policy research as the first step, to law enforcement supervision, special rectification as means, comprehensive use of laws and regulations, economic policies and other ways, to promote the relevant units in accordance with the law, scientific, ahead of the safety management, accelerate the formation of pipeline facilities protection work responsibility system.
To strengthen the construction of the legal system, efforts should be made from the source of the legal system to supervise and manage according to law.
The staff of pipeline enterprises should first be familiar with the regulations and do things according to law; Cooperate with local authorities to carry out mass publicity and education activities to improve the legal awareness and consciousness of pipeline facility safety. Compile oil and gas pipeline safety education books and distribute them to grassroots units. Compile a well-illustrated and easy to understand Pipeline Protection Publicity Manual, ** distribute it to the local people, and cooperate with local authorities in publicity work.
Oil and gas pipeline enterprises should coordinate, cooperate and communicate with all departments of the government and relevant links of the society. Give full play to the role of special rectification activities of public security and order in oil and gas fields and oil and gas pipeline production, include the administrative departments of urban construction and land planning, and clarify their respective responsibilities. Gradually explore the establishment of oil and gas pipeline safety supervision long-term mechanism.
Pipeline enterprises should focus on improving the organization, system, responsibility, supervision, system and fund guarantee, improve the post responsibility system, and implement the main responsibility of enterprise safety production; Perfect the emergency plan, strengthen the organic combination with the emergency plan; Strengthen the monitoring and control of major hazard sources; To set up signs and warning marks for oil and natural gas pipelines; Improve HSE(health, safety, environment) management system; Strengthen the safety skills training of managers and staff at all levels; Research and development of data technology and management technology; Increase investment in science and technology, improve the level of technical equipment and pipeline and laying quality.
To govern enterprises according to law, we should have legal consciousness and improve the ability to handle affairs according to law. Strengthen the construction of legal system, improve the level of operation and management, and achieve legal and compliant operation; Strengthen legal education and publicity to create a good management environment; Equipped with professional legal personnel to protect the rights and interests of enterprises according to law; Strengthen the enterprise culture construction, set up the enterprise honor and disgrace concept, truly form the public opinion environment governing the enterprise according to law.
