LNG Low Temperature Butterfly Valve
Introduction:
Low temperature butterfly valve refers to a butterfly valve that can be used in low temperature conditions. Usually, a butterfly valve with a working temperature below -40 °C is called a low temperature butterfly valve. Cryogenic butterfly valve is one of the indispensable equipment in petrochemical, air separation, natural gas and other industries. Its quality determines whether it can be produced safely, economically and continuously.
Applications:
Mainly used in ethylene, liquefied natural gas and other chemical plants, the output liquid low temperature medium such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., is not only flammable and explosive, but also needs to be gasified and gasified when heating up. , the volume expands hundreds of times.
Features:
1. According to the requirements of the working conditions, the low-temperature butterfly valve has connection methods such as flange, wafer, butt welding and lugs.
2. Based on the flammable and explosive characteristics of low-temperature media such as LPG and LNG, the low-temperature butterfly valve has designed fire prevention measures.
3. For the temperature higher than -50℃, the long-neck structure is generally not used. For the butterfly valve whose temperature is lower than -50℃, the long-neck structure is adopted.
4. The low-temperature butterfly valve is suitable for the management system of low-temperature liquid storage and transportation equipment. It has the characteristics of flexible switching and reliable sealing. It can also be used in other low-temperature and cryogenic media management systems.
