Vehicle refueling (gas) station, light fuel oil and liquefied petroleum gas
Technical specification for the blocking explosion-proof oil tank truck
This standard is applicable to the blocking explosion-proof technology vehicle refueling (gas) station of tank and motor transport for light fuel oil and liquefied petroleum gas blocking explosion-proof oil tank technical requirements make provisions, application design, manufacture, installation and acceptance requirements. The blocking explosion-proof technology in automotive fuel (gas) used for light fuel oil and liquefied petroleum gas storage tank and motor transport station, can prevent the fire, because the electrostatic, welding, shooting and collision accidents caused the explosion, to improve vehicle refueling (gas) station tank body and transportation tank safety, ensure the great the One, the standard uses the following definitions
1, the explosion barrier material
Made of special alloy mesh or other shape material, this material is filled in the flammable liquid and flammable gas storage tank can obstruct the flame propagation, thereby preventing the explosion.
2, the blocking explosion-proof device
Device is composed of the explosion barrier material and supporting components, the device is installed in the storage and transportation of flammable liquid and flammable gas tank explosion, can prevent the internal electrostatic, fire, welding, shooting and collision accident.
3, the blocking explosion-proof oil (gas) tank installed the barrier explosion proof device in the interior of the light fuel oil and liquefied petroleum gas storage tank.
Two basic requirements, technology
1, the blocking explosion-proof device should be compatible with the containing medium properties;
2, install the barrier explosion proof device should not change and affect the performance of the tanks;
Install and use the process of 3, the blocking explosion-proof device, at the bottom of the tank should not have debris;
4, the normal use of blocking explosion-proof device installation does not affect the storage tank.
Three, the explosion barrier material requirements
1, the quality of the appearance of:
The explosion barrier material should mesh size uniform, not uniformity is less than or equal to 25;
The explosion barrier material grid per square meter of damage does not allow more than 5, and each at the damaged area is less than or equal to 60mm; the explosion barrier material finished surface roughness of less than or equal to 60mm;
2, material and structure size
The barrier structure of explosion-proof material size, length tolerances to 0.5mm.
Four, tank cleaning requirements
1, the implementation of barrier protection technology before cleaning;
2, the implementation of the blocking explosion-proof technology tank cleaning of tank in tank and different scheme;
3, the new tank cleaning: Inspection and test to determine the tank leak test, selection of cleaning agent for cleaning the appropriate;
4, the cleaning tank explosion proof barrier after technical transformation: in order to ensure the quality of storage medium tank should be reformed, tank cleaning cycle of regular cleaning, and surface of the tank wall and the explosion barrier material free of dirt cleaning first when the inner shaft in taking out, and then use the shaft and cleaning channel space to clean the tank; before washing, shall check and determine the tank leakage, leakage, should repair welding for no leakage.
5, to ensure the construction safety of storage tank explosion barrier technology transformation process, deal with the storage tank for cleaning before transformation.
Five, technical documents
1, inspection certificate:
The blocking explosion-proof technology tank should have certificate of inspection, certificate of inspection should install the unit name and type, test date and inspector code etc.;
2, the use of manual:
The blocking explosion-proof technology of tanks should be instructions for use and includes the explosion barrier material shelf-life, cleaning and maintenance requirements.
3, the blocking explosion-proof tank marker technique:
Nameplates shall be provided on the product front significant position;
The nameplate shall include the following contents:
The blocking explosion-proof type storage tank; the number; the model; the testing unit; the construction unit; the date; the use of units.
In six, the qualification documents requirements:
1, the installation unit qualification certificate: business license, petrochemical equipment installation engineering contractor level three (or above) qualification certificate, construction safety production license and construction of special operations personnel qualification certificate; (has)
2, the state work safety supervision departments for the record: the explosion barrier material must obtain the work safety supervision bureau achieved record card. (for)
