China Drying Network News recently held in Shandong Province Petrochemical industry equipment management experience exchange meeting, Shandong Petrochemical Equipment Management Association Wang Xinglai proposed at the meeting, with the rapid development of enterprises, the large-scale installations, corporate groups The new situation of the promotion and application of chemical, new process and new materials, and energy saving and emission reduction all put forward higher requirements for the management of special equipment. To this end, he and the participating experts made suggestions on strengthening the supervision of special chemical equipment. Experts called for the supervision of special equipment such as urea synthesis towers in the fertilizer industry, autoclaves in refineries, and important pressure pipelines to keep pace with the times, innovate continuously, and improve the overall management level.
The first is to grasp the quality and safety of equipment from the source. Equipment selection should be conducted according to design requirements for review, verification of operating parameters, and design of operating procedures and maintenance procedures in accordance with design requirements. Equipment design institutes should be designed in accordance with standards and consider that the equipment is easy to manufacture, easy to operate, and safe and reliable. The manufacturing unit must strictly follow the drawings and carry out the construction. In particular, the manufacture of pressure vessels must ensure quality and safety. Experts reminded that the AQSIQ intends to implement the container manufacturing quality recall system in the near future and should pay attention to it.
The second is to continue to focus on pressure pipeline management. With the commencement of the comprehensive registration and registration of pressure pipelines, the inspection and inspection of pressure pipelines has been put on the agenda. Chemical companies should step up efforts to do the appropriate work, speed up the implementation of inspection plans for important pipelines, and accelerate the implementation of the renewal plan for old pipelines with incomplete data and unclear materials. In view of the low rate of detection of individual pressure pipelines and the hidden dangers of accidents, the competent authorities at all levels should strengthen supervision and promptly supervise and urge them to carry out rectification so as not to cause losses that the company should not have.
The third is to do a good job in basic equipment management. The in-depth implementation of the work safety standardization construction is an effective measure to implement the safety licensing system and strengthen the management of the source. It is an important method for constructing the “one science and technology, system, and supervision†trinity protection system and is an effective way to establish a long-term safety production mechanism. Chemical companies should take the opportunity of compulsory safety production standards upgrading work, and comply with the requirements of the “Common Operational Safety Standards for Hazardous Chemicals Operatorsâ€, combined with the actual conditions of the units, adjust measures to local conditions, and perfect the equipment management systems and mechanisms, especially for special equipment and major hazards. The source management and accident emergency rescue system shall initiate standardization work in a creative manner and effectively improve the level of equipment safety operation and safety protection capabilities.
Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.
