A problem during the unloading of tank trucks
Thread Content
Requirement 3.2.11 h of Q/SY 1431-2011 states that —— the grounding terminal dedicated for static electricity must be more than 1.5 m away from the oil loading and unloading ports. What are the reasons given? Please have the experts conduct an in-depth analysis; thank you~
It is probably because safety distances during loading and unloading need to be considered, so too close is not advisable
Q/SY1431-2011 3.2.11 h specifies that the distance between the connection point of the static grounding wire and the tank truck and the filling port should be greater than 1.5 meters； Currently, the static grounding of tank trucks is accomplished using static clamps ； The gripping point of the clip is the connection point ； Given that the clamps used by most manufacturers are not explosion-proof, and there is a risk of them loosening during the unloading process, resulting in unstable connections that could lead to sparks, this 1.5-meter distance is provided to ensure that the connection points remain in explosion-proof zones 0 and 1 ； You may consider the clamps with explosion-proof certificates offered by Shijiazhuang Beian Technology ；
It’s probably to prevent oil and gas from splashing onto the terminals and causing a fire
Prevent discharge from igniting the volatile vapors around the discharge port.
Prevent discharge from igniting the volatile vapors around the discharge port.
Oil and gas evaporate from the pipe outlet; the area within 1.5 meters is a zone prone to explosions, and static discharge during terminal connection can easily generate sparks
Regarding the safety distance issue, consider that static electricity clamps may generate sparks
