User Anxy asked: The State Administration of Work Safety recently announced that the five departments of the State Administration of Work Safety and the Development and Reform Commission jointly issued a notice requesting the strengthening of urban and rural planning and construction and pipeline engineering design safety management. Now, in urban and rural planning and pipeline engineering design. What are the common problems? How to set up safety protection and measures in oil pipeline design?
Expert Q & A: Chen Jianmin, expert of oil and gas storage and transportation of Sinopec Xuzhou Pipeline Company
1. It is understood that the general urban and rural planning and design does not consider the reserved long-distance oil and gas pipeline channel (pipe corridor), which has not been found in the literature. How to avoid oil and gas pipelines in urban and rural construction, there is no standard to rely on, and randomness.
2. The oil and gas pipeline engineering design follows the “Petroleum and Natural Gas Pipeline Protection Lawâ€, and the pipeline generally bypasses the town. At present, the old pipeline is under the pressure of the town, and the town is built afterwards. Many building (construction) buildings violate the law in accordance with the provisions of the "Pipeline Protection Law", but it is unclear who will correct it and who will punish it. The regulatory authorities can't manage it. Enterprises have no law enforcement power and can only let this serious situation happen.
3. In the process of safety protection design of pipeline engineering, in addition to complying with the “Pipeline Protection Lawâ€, according to the requirements of the “Pipeline Protection Lawâ€, set ground marking, set overpressure protection system, set various leakage monitoring systems, SCADA automatic control system. Industrial TV monitoring, cut-off valve room, full-time patrol line team, professional rushing maintenance team and so on.
4. The corresponding pipeline design specifications are:
