The method of prevent the accumulation of static electricity
Prevent the accumulation of static electricity
the flow rate and flow rate. Strictly implement the initial flow rate lm/s and
the maximum flow rate and flow rate of the operation.
The flow rate requirements of the inlet and outlet of the receiving cargo
For horizontal inlets, the liquid level of the cargo must be 0.6m below the top
of the inlet (no liquid disturbance and turbulence) before the speed can be
The downward-curved inlet should meet the requirement that the distance from
the lower port of the pipe side to the surface of the cargo has exceeded twice
the distance of the inlet pipe diameter before the speed can be increased.
For the upward-curved inlet, the nozzle must meet the distance of 1.2m or more
from the nozzle to the liquid level of the cargo in order to increase the
Floating-top cargo tanks should maintain a flow rate of lm/s until the top of
the tank starts to float (including internal floating cargo tanks with fixed
tank tops) in order to increase the speed to prevent rapid turbulent static
When sampling hazardous chemicals, ensure that the flow rate does not exceed
lm/s, and prevent the liquid from splashing and accumulating static
When a dangerous liquefied product ship arrives at the port or has just
finished loading and unloading the cargo, the container should stand for 30
minutes before sampling, temperature measurement, and rule measurement
operations can be carried out.
During the sampling, measurement and temperature measurement of liquid
hazardous chemicals, the speed of action shall be controlled, and the speed of
lifting and lowering the instrument shall not be greater than 0.5m/s
It is recommended to use Personal Electrostatic Eliminating Alarm.
