Composite Pressure Vessel

Product Overview

Composite pressure vessels are advanced containers designed to store compressed gases under high pressure with high strength and low weight. These vessels are widely used in hydrogen energy systems, CNG vehicles, industrial gas transport, medical oxygen supply, and safety equipment.

There are four main types of composite pressure vessels based on liner material and fiber reinforcement structure

Type I
All metal structure typically made of steel
Heaviest type with the lowest weight efficiency

Type II
Metal liner partially wrapped with glass fiber composite in the hoop area
Lighter than Type I with improved strength

Type III
Metal liner fully wrapped with continuous composite fibers
Excellent strength to weight ratio and long service life
This is the type we specialize in manufacturing

Type IV
Plastic liner with full composite fiber wrap
Lightest structure used in weight sensitive applications
Lower gas barrier performance compared to Type III

Among these types Type III composite pressure vessels offer the best balance of gas compatibility structural strength and long term reliability This type has become the preferred choice for demanding energy and industrial applications

Structural Advantage of Type III

Type III vessels use a high strength aluminum liner that provides a stable gas barrier and ensures compatibility with hydrogen oxygen and CNG gases The outer body is fully overwrapped with carbon fiber glass fiber or hybrid composite through advanced filament winding This results in reduced overall weight without sacrificing pressure resistance
