Product Introduction
The continuous fiberglass strip reinforced PE composite pipe is a new type of structural wall pipe composed of three layers: polyethylene-based resinas the innerand outer layers,and fiberglass composite strip pre-impregnated with polyethylene resinas the reinforcing layer through continuousspiral windingand fusion.
Compared with PE solid-wall pipes,it significantly improves pressure resistance and expands application fields.Italso enhances temperature resistance,impermeability,chemical corrosion resistance,andscratch resistance.

Product Advantage Analysis
Compared with steel wire mesh pipes of the same specification and pressure rating,the weight of continuous fiberglass strip reinforced PE composite pipes is reduced by approximately 1 5 \small { ~ } 3 0 % Compared with PE solid-wall pipes,theweight is reduced byabout 3 0 % ~ 4 0 % .Compared with steel skeleton PEcomposite pipes,theweight is reducedby over 3 5 % .The higher the pressureand diameter,the more significant the weight advantage.
Continuous fiberglass strip reinforced PE composite pipes of the same specification can achieve higher pressure ratings,up to 3.5Mpa currently.
