Filament winding

Filament winding is a precision technique for crafting Type IV pressure vessels, wrapping carbon fiber strands around a cylindrical mandrel for strong yet lightweight structures. Ideal for high-strength applications, this method ensures durability and efficiency.

Type IV pressure vessels utilize filament winding, combining carbon fibers with  epoxy resin for enhanced strength and durability. This advanced construction ensures high mechanical properties, including tensile strength and corrosion resistance. Resulting in lightweight vessels with superior gas containment capabilities, ideal for various industries.

Filament winding technology delivers precise fiber placement and uniform distribution, creating strong, lightweight Type IV pressure vessels. The use of carbon fibers and epoxy resin ensures corrosion resistance and durability. Ideal for storing and transporting gases like compressed natural gas (CNG) and hydrogen (H2), these vessels offer exceptional mechanical properties.

Burst test facility

The burst test facility is crucial for ensuring the quality of Type IV pressure vessels for CNG and hydrogen. By subjecting these vessels to extreme conditions, it verifies compliance with safety standards, reducing risks in storage and transportation.

A burst test facility evaluates pressure vessel integrity and safety:


1. Test Chamber: Reinforced chamber with safety measures.
2. Pressure Control: Precise pressure control system.
3. Data Monitoring: Instruments record parameters.
4. Test Procedure: Gradual pressurization of vessel.
5. Burst Test: Pressure increases until failure.
6. Data Analysis: Examination of vessel behavior.
7. Compliance: Results compared to standards for certification.
