Metal tank mine security seal labels

1, the sealing metal tanks. Tank wall thickness greater than or equal to 4mm, generally do not install a lightning rod for anti-lightning only grounded, grounding resistance should not exceed 30 ohms can be. 2, respiratory cutting with flame arrester, and hydraulic valve Fixed Length plastic seal airtight metal storage tanks, tank wall thickness and greater than or equal to 4mm thick cover, you can take to protect themselves, as long as its connecting piping and other metal parts, etc. a good electrical connection, and is linked with the grounding of at least two points, do not install a lightning rod. 7 F; D +} 6 X # D3 X 'X 

3, for external floating roof tanks, due to the oil tank with the liquid level of the roof lifting and floating storage tanks inside the small air gap can form an explosive mixture, and is Fixed Length plastic seals between the floating roof and the tank wall The. Paranoia can not install lightning rods, grounding can generally only. But floating roof storage tanks of metal, use a jumper can be scrambling to get connected with the metal tank body, and through the tank body grounding, grounding resistance should not exceed 10 ohms. For internal floating roof storage tanks, although the floating part and bottom of the tank, tank top to make good electrical connections and grounding reliable, but because the space floating roof tanks and tank top floating disc between explosive mixtures may be gathered, it is also need to set up lightning protection measures. 3 J "h # w9 [6 G -? R (^ * _ z, H / K 

4, for other storage tanks should be located lightning, lightning best set individually, but also allows welding tank top or at the edge of the circle plate. For the dome roof tanks need to be welded a 40mm, a thickness of 4mm steel plate, then loaded needle. 

5, seal testing and analysis before replacing via text summary, a seal floating roof tank using more advanced soft fixed length plastic strap seal and seal well testing and maintenance. Especially for elastic sealing filling (soft seal), adhesive bonding between the sealing tape has a certain warranty period, you must use in order to ensure the quality of the seal in the warranty period. For elastic padding seals (soft seal), should be checked once every six months sealing effect, during the thunderstorm season, should be checked once a month during the overhaul of the tank to replace the plastic truck seals. 

6, floating roof tank after tank fire for fire fighting personnel on whether to allow the tank to fight the proposed reference standard "Flammable and combustible liquids storage tanks at atmospheric pressure inside and outside the fire", according to the people-oriented concept, according to the actual conduct of fire reasonable risk analysis by the field commanders to determine the appropriate fire-fighting strategy, the decision on whether to send personnel to fight the tank. 

7, the application of aluminum dome aluminum tank dome designed by a professional installation company in the application of the design pressure of the oil tank battle diameter Φ60m look, install aluminum dome on the running battle tank is feasible.
