Natural gas storage tank adopts foreign-advanced multi-layer wrapping technology and is designed, manufactured, inspected and accepted in strict accordance with national standards. It has the following features:

1.High safety: the tank material is of good plasticity and toughness, even stress and rational stress distribution; the tank body is provided with safety signal hole to ensure safety.

2.Good corrosion resistance: the tank body uses 16MnR low alloy steel as major material; the carbon equivalent and hardness is controlled so as to effectively resist H₂S stress corrosion.

3.Excellent fatigue resistance: finite element is used for fatigue analysis design so as to ensure fatigue resistance of equipment.

4.Long service life: the equipment is designed to have cyclic fatigue times of 80000 times and service life of 30 years.
