Advantages of the Composite CNG Tube
1. Advanced Technique, High Safety and Reliable Quality
Top-notch wrapping technology and fatigue strength design can realize stable and uniform fiber tension. It also effectively overcomes the problem of fatigue failure when in use of large-diameter long pipes.
The rotational speed of the composite tube is controlled by a microprocessor in a curing oven, which can prevent the liquid resin from flowing and also realize a highly uniform curing process. By doing so, we can obtain a high-quality resin matrix to ensure high safety and reliability of CNG pipes.
Before a hydrostatic test is started, the metal liner and composite layer must be very tightly connected together so as to extend the fatigue life of the composite CNG tube.
Built to meet ISO 11515:2013 standard, the composite jumbo tube will withstand the following tests.
Hydrostatic test and volumetric expansion test
Liner burst test
Jumbo tube burst test
Cyclic pressure testing at normal temperature and extreme temperature
Blunt impact test
Fire test
Coating test
Salt spray test
By simulating the working conditions of our composite CNG tube, the above-mentioned tests effectively guarantee high safety and stability of the trailer tube.
