No.1：Preparation for the removal of large equipment
（1）The hoisting site shall be smooth and unimpeded.
（2）For the scope of the crane work and the road, the underground facilities and soil pressure resistance should be checked, and protection should be carried out if necessary.
（3）The commanding and operating personnel involved in hoisting shall be familiar with the performance and operating procedures of the crane
（4）It is necessary to check the rigging used in detail to confirm that its performance is safe and reliable, add sufficient lubrication grease, and solve any problems in advance.
No.2：Large equipment removal process
Reinforcement of structures, removal of electrical instrumentation cables and Bridges (to prevent re-burning of cables when cutting pipelines, At the same time, it also prevents the short circuit of the exposed copper wire, etc.), the removal of the equipment and pipeline insulation layer (because the thermal insulation layer can produce a large number of harmful gases after combustion), the removal of the pipeline, the removal of the vehicle, the removal of the equipment (there is a large equipment lifting but also the preparation of the lifting plan), and the transportation to a safe place and properly placed.
Before the fully usable equipment is dismantled, protective measures should be taken for the equipment, such as setting up protective guardrail and wrapping it with parcels. After the pipe is dismantled, all interfaces of the equipment should be wrapped with plastic sheets in a timely manner.
NO.3 Precautions for dismantling large equipment：
(1) Due to the burning of the plant, the performance of the metal may change, so that the support, equipment lifting lugs, etc., may not be able to withstand the load previously designed, so the construction personnel try not to step on the pipeline and equipment and use a ladder or operating platform for construction, lifting, try not to use the lifting lugs on the original equipment
(2) Each fire point should be equipped with fire extinguishing equipment, and the ground must be covered with fire blankets and monitoring personnel when the fire is hot.
(3)Due to the burning of the plant, the stress of the pipeline may be greatly changed, so when cutting the pipeline, loosening the pipe clamp and loosening the bolt, protective measures should be taken to avoid being hurt by the pipeline.
(4)When the equipment is removed, it is necessary to avoid scratching and knocking the equipment body, to be lightly hung, to avoid direct contact between the equipment body and other metals or the ground, and the middle should be padded with wood.
(5)When the pipeline is dismantled, it should be carried out lightly, and should not be carried out barbarously, smashing the equipment and the ground, or damaging and scratching the flange sealing surface of the interface with the equipment.
(6)In the transportation of equipment that needs to be repaired, it is necessary to avoid the phenomenon of small diameter pipe mouth distortion, the damage of auxiliary instruments, and the scratch of flange sealing surface.
(7)The equipment to be repaired shall be placed in the location specified by the owner as required. When replacing parts, the construction unit must provide corresponding tools and special tools, and construction shall be carried out under the guidance of the equipment manufacturer.
