What material is used for automotive natural gas tanks?
2 Answers
Automotive natural gas tanks are made of stainless steel. The specific details about automotive natural gas tanks are as follows: 1. Automotive liquefied natural gas (LNG) storage tanks: These are high-vacuum insulated containers used to store liquefied natural gas in vehicles. They feature a double-layer (vacuum) structure. The inner tank is designed to store low-temperature liquid LNG, with multiple layers of insulation material wrapped around its outer wall, providing excellent thermal insulation. The jacket (the space between the two layers) is evacuated to a high vacuum, creating an effective insulation system. The outer shell and support system are designed to withstand the external forces generated during vehicle operation. 2. Purpose: Automotive compressed natural gas (CNG) cylinders are mainly used for long-term, fixed installation of compressed natural gas in vehicles. They offer advantages such as high pressure, large capacity, lightweight, and safety and reliability. They are primarily used in taxis, minibuses, buses, and other vehicles in major and medium-sized cities.
As an automotive enthusiast, I've researched the materials used for vehicle natural gas tanks. The most common type is steel tanks, known for their high strength, relatively low cost, and ability to withstand high-pressure gas without rupturing. Another option is carbon fiber composite tanks, which are lightweight and more durable but come at a higher price. Material selection depends on safety standards and vehicle requirements. Steel tanks have a long history of reliable performance, though their heavier weight can increase fuel consumption. Carbon fiber tanks help improve energy efficiency, making them particularly suitable for urban buses or taxis. During manufacturing, tanks undergo burst tests and anti-corrosion treatments to ensure driving safety. Regular inspections for scratches or rust are necessary during use, and prolonged parking in high-temperature environments should be avoided. If converting to a natural gas system, always have professional shops install tanks from reputable brands for peace of mind while driving.
