Imported valves and electrical (pneumatic) components should be protected and covered with hard materials. 3. 13 All installed constant-force hangers and spring hangers must be maintained regularly, and locating pins and stop pads shall not be taken out before water pressure test and flushing to prevent overload. 3. 14 small-diameter pipelines (including instrument pipelines, sampling pipelines and adjacent heating furnace pipelines) should be marked and protected during installation to prevent damage caused by human trampling. 3. 15 All unconnected nozzles and instrument joints shall have reliable temporary plugging measures. 3. 16 If all operating mechanisms, lighting boxes, terminal boards, panic button and travel switches are turned on. When arranging in the open air, rain cover should be installed in time. 3. 17 installed instrument sockets, thermocouples and other instruments should be clearly marked to prevent collision and trampling. Especially the thermocouple on the boiler wall, measures should be taken to prevent it from being damaged by electric and fire welding. 3. 18 When pressure gauges, thermometers and pressure transmitters are installed in rows, measures such as anti-collision, fire prevention, moisture prevention and dust prevention should be taken and labeled. 3. 19 After all thermal and electrical panels and cabinets are installed in place, warning signs must be hung. When arranged in the open air, good rainproof measures should be taken, and appropriate covering and isolation measures should be taken at the intersection with civil works. Lock the screen and the door behind the cabinet in time after work. 3.20 Maintenance and lifting facilities arranged in the open air (such as electric hoists for blowers and induced draft fans) must have good rainproof measures, and operating handles should be properly stored. 3.2 1 After the complete sets of factory-supplied equipment in chemical dosing sampling room, condensate polishing room and hydrogen production station are installed in place, anti-theft should be strengthened. 3.22 In the process of thermal insulation and metal external protection construction, the construction contractor should strengthen on-site inspection, and the installed parts should be hung with warning signs in time or take corresponding protection or isolation measures. 3.23 Pollution prevention measures must be taken for installed metal external protection. It is strictly forbidden to dismantle, hang wire rope, walk and trample, sit and lie down or rely on other materials without authorization to ensure the metal external protection is in good condition. 3.24 The equipment delivered to the site but not installed in time must also be maintained, and its requirements are consistent with those of the installed equipment. 3.25 Underground ditches, pipes, cables, etc. It should be conspicuously marked on the ground along the trunk line. 3.26 After the cable laying, it should be covered with asbestos and other fireproof materials before the cover plate is formally installed. 3.27 After the installation of the on-site oil station is completed, an isolation shed shall be set up. 4. Scope of responsibilities 4. 1 The civil construction contractor shall be responsible for the protection and maintenance of the civil foundation before handing over the site; After handover or on-site handover, the receiving unit shall be responsible for the protection of civil finished products. 4.2 The installation contractor shall be responsible for the protection and maintenance of the equipment being installed or being installed before entering the next process. 4.3 When the installed equipment enters the debugging stage, the debugging unit shall be responsible for the damage of the finished equipment caused by debugging. 4.4 The custody and maintenance of the equipment after the trial operation of the Division shall be handed over to the power plant for custody, and shall be implemented in accordance with the relevant provisions of the Equipment Custody Agreement.
