1. Summary
This apparatus works under a certain pressure and at temperature of 37.870ºC, to test the pressure of liquefied petroleum gas. It is conform to GB/T6602 and ASTM D1267 standard. The apparatus is suitable for those liquefied petroleum gas whose boiling point is higher than 0ºC, and hydrocarbon content is lower than 5% and steam pressure is lower than 1550Kpa.
2. Apparatus characteristics
valves are made by 1Cr18Ni9Ti,can hold pressure of 4Mpa.
Cylinder is made by Plexiglas; two ends are sealed by metal plate and rubber.
water bath is made by 1Cr18Ni9Ti with heating and motor-stirring device,temperature auto adjust to meet test condition 15±0.2℃ or 20±0.2℃.
Digital display temperature control device, react sensitively, high temperature control precision.
Stirring device is composed of motor, stirring stick and vanes, low noise and high effect.
