It is reported that the hydrogen container tube bundle developed and launched by Enrico in Shijiazhuang (multiple hydrogen cylinders to be designed to connect and fix together) is an innovative product in the field of high-pressure hydrogen transportation. This product is mainly equipped with large-volume steel liner circumferentially wound gas cylinders and wound bottle containers. Among them, the large-volume steel liner ring-wound gas cylinder is wound with high-strength glass fiber on the outside of the seamless steel cylinder, which reduces the overall equipment weight of the hydrogen cylinder and increases the transportation capacity under the same nominal working pressure, effectively improving the transportation efficiency and effective transportation weight of the long tube trailer are very popular among customers. According to the relevant technical person in charge of Enrike in Shijiazhuang, the wound bottle containers are all six-sided fully enclosed structures, which can effectively solve problems such as solar radiation, external impact, and fire; measures such as fixing and fastening are taken internally to prevent the cylinders from rotating and moving back and forth, integrating the entire box, increasing the rigidity of the box, and solving the problem of the impact of complex road conditions on the wound container during road transportation. "At present, in the domestic market, only our product has obtained the 'Type II Bottle (Wrapped Bottle) Type Test Certificate' and can be sold." "This cooperation is also a key measure for both parties to leverage their respective leading technological advantages to support the development blueprint of the hydrogen energy industry under the national" 13th Five-Year Plan "." The person in charge said.
