Connecting pipe extension
Connecting pipe flange adopts raised plate type welding flange, nominal pressure PN=0.6M Pa, flange standard is \HGJ45-91 (except instrument interface). Foam fire fighting and water sprinkler system use raised plate type flat welded steel pipe flange: nominal pressure PNIMPa, flange standard is GB9119.7-882.7
This standard storage tank is equipped with two sets of liquid level indication devices, one is a float type steel belt liquid gauge, and the other is a differential pressure level gauge.
Ladder, platform
This standard stipulates that 100m~300m storage tanks use straight ladders, 40/m The tanks from 10m to 30000m are equipped with spiral ladders, with a spiral rise angle of 45. Shenzhen Fire Brigade
Semi-standard tanks use foam fire fighting, and different numbers of air bubble generators are set according to the volume size.
2.S.# Fire sprinkler installation pipe
R. Storage tanks that need to be equipped with water sprinkler devices, this standard stipulates that 10m to 800m storage tanks are only equipped with top water sprinkler devices: 10j0m~~30000m storage tanks, storage tanks, and tanks are all equipped with water sprinkler devices. Detailed table 2. 8. 2-1 Table 2. 9. 2-20 Heater type This standard specifies the use of coil or door heaters according to the tank diameter and the size of the heating area. For tanks that need to be equipped with heaters, the heating area of ​​the heater can be selected according to Table 2.10 and indicated in the selection table.
Tank wall reinforcement ring
This standard stipulates that tanks with a nominal volume of less than 1000m3 do not need to be equipped with reinforcement rings, and tanks with a nominal volume equal to and greater than 1000m3 are equipped with reinforcement rings. Tank heater data Installation
