Before filling the LNG storage tank with sand, the pearl sand is specially dehydrated and pretreated

Sixth, the pearl sand is specially dehydrated and pretreated before filling the sand, and the interlayer is heated and replaced with nitrogen, which greatly reduces the degassing source.

The inner and outer surfaces of the carbon steel shell of the LNG storage tank are sandblasted and rust-removed

The LNG storage tank uses negative pressure filling and positive pressure compaction technology
