These are horizontal bullets installed for bulk storage of liquefied petroleum gas lpg.
Lpg mounded storage bullets.
Mounded storage is generally safer than other methods of storing the highly inflammable lpg.
Lpg may be liquefied by moderately increasing the pressure or reducing temperature refrigerated storage is used by suppliers to store large volume of lpg the main form of lpg storage is lpg bullets normally 85 of capacity is filled with liquid and the remaining space being taken up with vapor.
The mounded bullets are designed as per asme sec.
Mounded bullets allow storage of large quantities of lpg up to 2 000 mt.
Lpg mounded bullets volumes are from 500 m3 to 20000 m3 total storage as well as refrigerated mounded for propane storage.
Storage options include spherical lpg pressure vessels and both above ground and underground mounded cylindrical vessels also called bullet tanks.
In mounded storage facility a mound of earth or suitable inert material is provided to cover the bullet this is kept above ground.
The use of mounded bullets allows for narrower spacing between adjacent lpg bullets as well as less strict safety distances with regards to other properties in close proximity.

We have executed storage facility including mechanical civil piping instrumentation and electrical.
Mounded or buried bullets are a trade off between available storage and the necessity to allocated extra civil and mechanical work to accommodate the actual mounding.
Offering a safer method for storing highly inflammable lpg.
Mounded lpg bullets are large buried horizontal cylindrical steel tanks with dished ends of size ranging between 3 5 to 8 5 meters diameter and lengths of 35 to 90 meters.

Existing lpg storage at oil duliajan includes 3 aboveground bullets each 360 m 3 and 2 spheres each 2000 m.
Mounded lpg bullets are large buried horizontal cylindrical steel tanks with dished ends of size ranging between 3 5 to 8 5 diameter and lengths of 35 to 70 meters or more.
Mounded bullets are horizontal pressure vessels which are intended for the pressurized storage of liquefied petroleum gas lpg under ambient temperature.
Oil proposes to replace the above ground lpg storage facility with mounded storage facility.
In mounded storage facility a mound of earth or suitable inert material is provided to cover the bullet which is kept above ground completely except for nozzles manhole covers.
