The reform of heating valve drip pipe solves the hidden trouble of oil and gas pipeline in China and the rectification difficulty

“The main valve of the heating pipe in our building is in the wall of my house. It has been leaking for two years, and it has all dripped onto my bed!” 28, live in Beijing Huairou District Xinghuai Street, Ms. Tang complained.
Ms. Tang said the large heating valve in the family’s cabin began dripping water onto the bed when the heating was tested in the winter of 2002. Since the house is only 6 square meters, she could not move the bed, so she spread old clothes on the bed to catch the water. “I went to the maintenance staff of Tianlian Heating station, which is responsible for heating the area, and they said they could not fix it, so they could only put a plastic bag on the valve to collect water.” Ms. Tang said helplessly.
For the next two years, Ms. Tang suffered from headaches every winter heating. “Before the heating test this year, my big valve dripped more seriously, sometimes even dripping scale, the heating station maintenance workers still can’t do anything about the big dripping valve.” “Ms. Tang said.
On the afternoon of 28th, Zhang, director of Tianlian heating station, said that after stopping heating next year, the heating pipeline of Ms. Tang’s home will be transformed, and the big valve will be moved out. To the question that the valve has been dripping for two years, Zhang did not answer directly, but simply said: “The pipe was designed this way.”
Oil and gas pipeline is hailed as a lifeline of the national economy. It is also a transportation way of safety of oil and gas resource, economy and environmental protection. It is estimated that about 70 percent of the world’s oil and 99 percent of its natural gas are transported by pipeline. At PRESENT, OUR COUNTRY HAS BUILT THE NORTHWEST, NORTHEAST, southwest, SEA FOUR OIL AND gas STRATEGY channel, three longitudinal and four horizontal pipeline corridor and the national backbone pipe network, with oil and gas pipeline total mileage has REACHED 120,000 KILOMETERS.
Rectification is difficult and hidden danger of oil and gas pipeline in China
It is difficult to rectify problems
In the wake of recent pipeline safety accidents in Qingdao, Shandong Province and Dalian, Liaoning Province, more than 30,000 oil and gas pipeline hazards have been identified. However, due to the influence of technical standards and capital investment, many pipeline risks are still in the situation of integration without change.
According to data released by the State Administration of Work Safety, a total of more than 30,000 oil and gas pipelines have been investigated nationwide this year, with an average of 1 hidden danger every 4 kilometers. As a traditional petrochemical province, Liaoning identified 2,773 pipeline safety risks, including 2,397 major risks, ranking first in China.
Relative to the existing security risks rectification difficulties, emerging new risks more worrying. Many interviewed people introduced that oil and gas pipeline hidden dangers repeatedly appear, including drilling, crude construction and other objective factors, but the pipeline safety planning implementation is poor, is an important reason for the safety hidden dangers repeatedly appear.
Experts said that the investigation and rectification of oil and gas pipeline safety risks is related to people’s lives and property and the security of the national energy system. No matter how high the cost and difficulty, great efforts should be made to promote the solution of hidden problems as soon as possible, while preventing and reducing the emergence of new hidden dangers.
Oil and gas pipeline network construction picked up
Oil and gas pipeline business has a distinct natural monopoly in China. It is generally believed that the construction of oil and gas pipeline network and the competition of more than one pipeline network project in a certain area are easy to cause the waste of repeated construction resources, so it is better to be operated by one enterprise. Therefore, it is reasonable for the government to impose entry and price controls on the oil and gas pipeline network industry.
However, in June this year, the company will be faithful to the fair and open implementation method of the oil and gas pipeline network facilities, and the scheme of attracting private capital to the oil and gas pipeline network issued by the Energy Administration will formally enter the substantive operation stage. Private companies are expected to get more pipeline orders after CNPC opened up fairly to private capital.
With the promotion of the construction of major energy channels in China, the demand for oil and gas pipelines is gradually increasing, and the construction of domestic oil and gas pipeline networks is entering a period of recovery. According to the 12th Five-Year Plan for Natural Gas Development, 44,000 kilometers of new natural gas pipelines will be built during the 12th Five-Year Plan, including 36,000 kilometers of trunk lines. Compared with the current 40,000 tons of pipeline network, the annual length of new pipelines will be nearly 90 million kilometers. It is estimated that during the 12th Five-Year Plan period, the construction of * main natural gas pipelines will bring the demand for oil and gas transmission pipelines to 10.8 million tons, resulting in a natural gas pipeline construction scale of more than 50 billion yuan.
We will promote the implementation of oil and gas pipeline networks
Oil and gas pipeline hidden danger or can be regarded as one of the influence of the monopoly of oil and gas pipeline network construction. Perhaps in the competitive environment without pressure, the oil and gas pipeline network construction company has relaxed the investigation and rectification of pipelines and hidden dangers, or it is unable to carry out the investigation and maintenance of 120,000 kilometers of oil and gas pipelines in the country efficiently and rapidly.
The experience of oil and gas pipeline network construction in the United States also shows that the economic rationality of each enterprise should not be underestimated. Competitors must weigh the costs and benefits when building pipelines. Only when the benefits outweigh the costs can pipelines be built. Moreover, competition may lead to some excess in the short run, but it is efficient in the long run and from a dynamic point of view.
When entering the competition stage, different oil and gas pipeline network construction enterprises undertake the construction of oil and gas pipelines respectively. The attention surface of construction units decreases and the attention increases. The division of responsibilities should be clarified, and legal and economic responsibilities should be divided according to the principle of who fails in duty and who bears responsibility, so as to curb the high incidence of hidden dangers of oil and gas pipelines from the source.
