LNG hoses, also known as natural gas rubber hoses, have a distinct structure, consisting of three main components: a rubber hose, a mesh sleeve, and a joint. The core of the LNG hose is a corrugated pipe. This corrugated design gives the hose exceptional flexibility. Specifically, the corrugated pipe has low longitudinal and bending stiffness. Moreover, since the primary parts of the hose are crafted from austenite, it boasts outstanding temperature and corrosion resistance. The LNG hose can operate across an impressively wide temperature range, from -196℃ to 600℃. When using it, you must select the appropriate hose according to the corrosiveness of the medium. This ensures the hose’s safety during operation. Additionally, avoid bending the hose beyond its minimum bend radius. Therefore, it can function smoothly within the rated bending radius.
Reinforcement and Connection of LNG Hoses
The construction of LNG hoses varies based on their diameter and the pressure they need to withstand. They can have one, two, or three layers. The mesh sleeve plays a crucial role as it’s the main pressure – bearing component of the rubber hose. In fact, the number of layers in an LNG hose directly determines its pressure resistance. The braided mesh sleeve used in natural gas rubber hoses not only enhances protection but also boosts the rubber pipe’s pressure – bearing capacity. As for the connection, the two ends of the natural gas rubber hose utilize flanges. Typically, flanges are made of carbon steel. However, the specific material can vary depending on the hose’s installation location.
Advantages of Natural Gas Rubber Hoses
LNG hoses offer several notable benefits. First, their pitch design provides flexibility, and the hoses themselves have excellent elasticity. Additionally, their smooth inner walls ensure that the medium flows through without any obstruction. Thanks to their wide working temperature range, these hoses remain flexible even in extremely cold weather. Moreover, gas rubber hoses are lightweight, which makes them easy to coil up and transport.
