Classification:Industry PublishTime:2020-05-04 16:51:31

Conventional design of LNG atmospheric pressure tank process pipeline


The supply scope of the pipeline connected with the storage tank is from the bottom of the storage tank to the back of the first elbow connected with the pipe gallery. The liquid inlet pipe is the first fixed frame before the automatic cut-off valve, and the liquid outlet pipe is the first fixed frame after the automatic cut-off valve (both including the automatic cut-off valve and the fixed frame). The Seller shall provide the calculation data of pipeline stress (including axial and radial loads) on the tank side of the fixed frame, The Seller shall be responsible for the internal stress compensation within the scope of supply. The Seller shall provide the civil engineering conditions of the pipe support within the scope of supply and the calculation data of the pipe stress on the tank side of the fixed frame (including axial and radial loads). The Seller shall be responsible for the pipeline stress compensation within the scope of supply; The interface with the design is in front of the inlet emergency shut-off valve and behind the outlet emergency shut-off valve.


The pipeline stress in its range is considered; The inlet and outlet of the storage tank shall be equipped with safety valves, the self pressurizing gasifier (the Seller shall provide the civil engineering conditions for equipment installation) shall also be equipped with safety valves, and the cold insulation of all supply pipelines shall be ensured.
