LNG hoses—also called natural gas rubber hoses—have three main parts: a rubber hose, mesh sleeve, and joint. Their core component is a corrugated pipe, which is highly flexible. This bellows has low longitudinal and bending stiffness, making it easy to maneuver. What’s more, key parts of the hose are made from austenitic materials. This gives the hose excellent temperature and corrosion resistance. LNG hoses work across an extremely wide temperature range: from -196℃ to 600℃. When using one, match the hose to the medium’s corrosiveness to ensure safety. Also, never bend it beyond its minimum bend radius. Sticking to the rated bending radius keeps it working smoothly.
Let’s look at the reinforcement and connections of LNG hoses
Depending on the hose’s diameter and pressure requirements, it can have one, two, or three layers. The mesh sleeve is the main pressure-bearing part of the hose. More layers mean better pressure resistance. The braided mesh sleeve used in natural gas rubber hoses not only strengthens protection but also boosts the pipe’s pressure-bearing capacity. The two ends of the natural gas rubber hose connect via flanges, usually made of carbon steel. However, the flange material can vary based on where the hose is used.
Natural gas rubber hoses offer several advantages
They have flexible pitches and good elasticity. Their smooth inner walls let media flow without blockages. They work across a wide temperature range and stay flexible even in cold weather. Additionally, these hoses are lightweight, making them easy to coil and transport.
