Is static bonding required for all pipes? Or is it only applicable to pipelines transporting flammable and explosive materials?
Static grounding is applied only to pipelines transporting flammable and explosive materials, as well as to positions and equipment that are prone to such hazards.
So, what are the main regulatory requirements based on?
These requirements are specified in standards such as SH3501-2002 and the \"GB 50235—97 Code for Construction and Acceptance of Industrial Metal Piping Projects\".
Standards such as the \"Regulations for Static Electricity Safety Inspections in Chemical Enterprises\" (HG/T23003－92) and the \"General Guidelines for Preventing Static Electricity Accidents\" (GB12158－2006) contain specific provisions on this matter. Additionally, the \"Safety Standards for Lightning Protection in Petroleum and Petroleum Facilities\" (GB15599-1995) and the \"Design and Construction Standards for Automobile Gasoline and CNG Stations (2006 Edition)\」(GB50156-2002) also have relevant regulations
The original poster, please take a look at this post: http://bbs.hcbbs.com/viewthread.php?tid=364823. What are the necessary conditions for adding an electrostatic bonding wire?
Pipelines for flammable and explosive materials are required only
There was a small private enterprise that was inspected by the Safety Supervision Bureau; one issue found was that the anti-static bonding for the kerosene pipelines was incomplete. The management instructed the company’s mechanical and electrical department to carry out the necessary corrections, specifying only that static electricity bonding was required; therefore, the mechanical and electrical department also performed bonding on the compressed air pipelines. Later, when the safety supervision department visited again, corrections and explanations were provided!
I earnestly ask all experts to help find the energy calculation formulas for low-temperature methanol washing and throttling flashing in cryogenic tanks. Thank you! ! ! ! ! ! ! ! !
Pipelines and equipment used for transporting flammable and explosive materials require static electricity bonding; this is not necessary for other types of piping equipment. However, pipelines used for transporting flammable and explosive gases must be grounded every 100 meters in order to discharge static electricity and prevent lightning strikes.
