LPG hose is to transfer gas or liquid LPG, natural gas and methane within 25 bar. Besides, it's also suitable for stove and industrial machines. At home, it always serves as the connection between gas tank and cookers such as gas stove.
Compared with other plastic hoses, LPG gas hose can work in a wider temperature range. While the work temp could be -32°C - 80°C. Thus it's more suitable for both low and high temp use.
Standard tolerance of the hose within DN20 should be within ±0.75mm; ±1.25mm for DN25-DN31.5; and ±1.5mm for DN40-DN63.
Tensile strength of inner tube is 7Mpa (10Mpa for cover). Elongation should be 200% for inner tube and 250% for cover.
Must bear 2.0Mpa without leaks or bubbles for over 1 minute. Length change rate at pressure should be within 7%.
Stored at -40°C for 24 hours without cracks. Passing the pressure test after returning to normal temperature without leakage.
Tested in 50pphm ozone content at 40°C for 72 hours, showing no cracks on the surface.
