　　In order to meet the requirements of international standards and design and quality control requirements, high density polyethylene (HDPE) and glass fiber are used in the "Anyida" LPG composite cylinder.


 

　　The structure of the “Anyida” LPG composite cylinder is:

High density polyethylene liner           
Liner is a non-load bearing LPG container.            
It is required that the wall thickness of the inner liner be controlled uniformly, the impact toughness is good, and no creep failure or stress cracking occurs during the service period.            
It has good air tightness, corrosion resistance and high temperature resistance.
 
Glass fiber reinforced layer            
Based on the finite element analysis, according to the lay design technology, wound on the liner.          The cylinder has enough strength, stiffness and stability under the condition of force.
 
Protective shell for HDPE cylinders            
It has good corrosion resistance, impact resistance, high strength, high toughness, weatherability, high temperature resistance, flame retardant and so on.
