Precautions for large-scale device removal

No.1 the preparation for the demolition 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 found out, and protection should be carried out if necessary.

(3) The commanding and operating personnel participating in hoisting should 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, if there are problems to be solved 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 transport to the best 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.3Large equipment removal needs attention:
(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 triggered at the height.

(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 handled, 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 lightly hoisted and put down, and it should not be brutally constructed, smash the equipment and the ground, and damage and scratch 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 the flange sealing surface.

(7) The equipment to be repaired should be placed in the location specified by the owner as required, and when replacing parts, the construction unit must provide the corresponding tools and special tools, and construction under the guidance of the equipment manufacturer.
